Machado de Assis o crítico : seduções e desencantos
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão.Estudo do discurso crítico de Machado de Assis, ativado a partir da segunda metade do século XIX, cuja discussão sobre a produção literária suscita uma reflexão acerca da natureza da arte e da sua relação com o cultural. Trata-se de uma pesquisa sobre as condições e constrições de possibilidade da prática crítica, passando pela noção de valor (como estratégia significante), pela questão do cânone e pelos processos de hibridação, modus operandi por excelência do discurso crítico machadiano
Salão de poses: retrato, fotografia e moda em Machado de Assis
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2015.De que maneira a ficção de Machado de Assis teoriza sobre a ideia de pose? Por outro lado, quais teorias sobre a pose sua ficção solicita? Ao procurar responder estas perguntas, e por entender que a pose é uma noção central para analisar a literatura machadiana, estou sugerindo a tese de que Machado entende a própria ficção como pura exterioridade e aparência, e assim fantasmagoria, captando então, ainda no século XIX, o que Guy Debord chamou, décadas mais tarde, de  sociedade do espetáculo . Em outras palavras, a literatura de Machado deve sugerir, solicitar ou mesmo oferecer, anacronicamente, uma teoria contemporânea para refletir sobre a imagem. Isso porque, em sua ficção, a pose mobiliza uma verdadeira constelação de conceitos; ela pode ser refletida no retrato, na fotografia e também na moda, exigindo portanto posições analíticas variadas. Em suma, Machado parece nos dizer que a passagem pela noção de pose é não apenas indispensável para refletir sobre sua ficção; mais do que isso, tal passagem apresenta consequências determinantes para repensar o lugar de sua ficção na sociedade contemporânea e, dessa maneira, relativizar grande parte das conclusões feitas a respeito de sua obra nos últimos anos.Abstract : How does Machado de Assis' fiction theorizes about the idea of pose? On the other hand, which theories his fiction requests in relation to a concept of pose? In seeking to answer these questions, and assuming that the pose is a central notion to analyze Machado's literature, I am suggesting the thesis that Machado understands his own fiction as both pure externality and appearance, and so phantasmagoria, then capturing in the nineteenth century what Guy Debord would call the "society of the spectacle" decades later. In other words, Machado's literature could suggest, ask or even offer, anachronistically, a contemporary theory to reflect about the concept of image. This is because, in his fiction, the pose mobilizes a real constellation of concepts; it may be reflected in picture, photography and also in fashion and costumes, therefore requiring different analytical positions. In short, Machado seems to tell us that the passage through the notion of pose is not only indispensable to reflect about his fiction: more than that, such a passage has major implications for rethinking the place of his fiction in contemporary society and, thus, for a large relativization of many conclusions made about his work in recent years
A composição do estilo do contista Machado de Assis
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2007Esta tese discute a percepção, ainda vigente em parte da crítica literária, de que a obra de Machado de Assis é cindida em duas partes, como se fosse possível a um autor ter dois estilos distintos. Amparada na revisão da fortuna crítica machadiana e com o método da estatística textual mediante a utilização do programa Hyperbase, compara bases de dados formadas pelo conjunto de contos de Machado, cotejando-os com os romances do autor e a base Portext. A análise exploratória dos dados permite descrever a anatomia do material que compõe o conto machadiano, enquanto as funções estatísticas viabilizam a busca de padrões e transformações no léxico e na distribuição do texto. Os resultados da análise qualitativa, ao indicarem que há poucas variações de classe gramatical e de vocabulário no material, contrapõem-se à ideia de ruptura estilística e reforçam a hipótese de que a transformação do estilo de Machado de Assis no conto é gradual e encontra-se fundamentalmente não no material linguístico, mas na composição
La Poetica della traduzione di Machado de Assis in italiano: o Anjo Rafael
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2010This thesis is based on a research project on the translations of Machado de Assis published in Italy. It aims to verify how and in what way the Brazilian author is positioned in Italian literary culture, and based on this it moves on to describe the importance of translational and critical activities in the reception of a writer from a peripheral literary system by another literary system. Peeter Torop#s concept of total translation is the main theoretical reference adopted for the individuation of the translational strategies for Machado de Assis# works in general, based on the stylistic description of his criticism, and of O Anjo Rafael [The Angel Raphael] in particular. This little known short story by Machado de Assis is presented, analysed and translated for the first time into Italian. In conclusion observations and commentaries on the translational process will show the poetics of translation adopted in this particular translation of Machado de Assis short story.Esta tese parte de um trabalho de pesquisa sobre as traduções de Machado de Assis publicadas na Itália para verificar em que medida e com quais características o autor brasileiro esteja inserido na cultura literária italiana, e da qual se parte para delinear a importância das atividades tradutória e crítica na recepção de um escritor pertencente a um sistema literário periférico em outro sistema literário. O conceito de tradução total de Peeter Torop é a principal referência teórica adotada para a individuação das estratégias tradutórias da obra em geral de Machado de Assis, com base na descrição estilística de seus críticos, e de O Anjo Rafael especialmente. Trata-se de um conto pouco conhecido de Machado de Assis que vem aqui apresentado, analisado e traduzido pela primeira vez para o italiano. As observações e os comentários sobre o processo tradutório concluem este trabalho, evidenciando a poética da tradução adotada na tradução específica deste conto de Machado de Assis
Experiências pioneiras de Machado de Assis sobre o jornal
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.A autora se propõe trazer à tona um instante pioneiro de experimentação do corpo móvel e público do jornal através da perspectiva de Machado de Assis na virada do século XIX para o XX. Tal perspectiva se dá, num primeiro momento, quando o autor carioca faz a travessia do livro ao jornal por intermédio da crônica, e, num segundo momento, quando faz a travessia ao revés: do jornal ao livro através de Memórias póstumas de Brás Cubas
Traducción comentada de "O espelho", de Machado de Assis, al espanhol
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2011Este trabalho discute aspectos da tradução do conto "O espelho" de Machado de Assis para o espanhol, a partir da tradução efetuada por mim com esse fim e da já realizada e publicada por Santiago Kovadloff. O componente fantástico do conto é explicitado e defendido no sentido de sua relevância para a tradução. Os comentários partem de exemplos concretos do texto retirados da tradução e do texto original e a discussão teórica está focada na presença do estrangeiro na tradução, na tradução da letra do conto - com atenção especial para o perfil colocacional do texto e para a imbricação forma-conteúdo - e no caráter literário da tradução - principalmente através do exemplo de uma Nota do Tradutor.This work discusses aspects of the translation into Spanish of the short story "O espelho" ["The mirror"] by Machado de Assis, having my own translation, carried out for this purpose, and a previous one by antiago Kovadloff as the objects of this discussion. The fantastic component within the short story is made explicit and defended as an important element to the translation. The commentaries start from examples of concrete text taken from the translation and the original text. The theoretical discussion is focused on the presence of the "foreignness" in the translation, on the translation of the "letter" of the short story - with special reference to its collocational profile and the intimate connection between form and content - and on the literary character of the translation - specially by means of an example based on a Translator's Note-
Laparocerus inermis Machado, 2007, n. sp.
No full textLaparocerus inermis n. sp. (Figs. 6 B, 12 C–D, G, 16 A, 18 M) Dimensions, holotype ( ɗ ). Length: total (without rostrum) 8.85 mm, head 1.85 mm, rostrum 0.95 mm, eyes 0.62 mm, scape 2.05 mm, funicle 2.10 mm, segments (1 st / 2 nd) 0.50 / 0.45 mm, club 0.68 mm, pronotum 2.15 mm, elytra 6.20 mm, and tibiae (pro- /meso- /meta-) 2.35 / 2.15 / 2.50 mm. Width: head (with eyes) 1.40 mm, head (between eyes) 0.80 mm, rostrum (with pterygia) 0.92 mm, rostrum (minimum dorsal /ventral) 0.66 / 0.80 mm, eyes 0.44 mm, scape (apicad) 0.20 mm, club 0.24 mm, pronotum (anterior /maximum /posterior) 1.70 / 2.60 / 2.30 mm, elytra (maximum) 3.90 mm. Height: abdomen 3.10 mm. Specimen slightly teneral. Differential diagnosis. Similar in appearance and structural details to L. hupalupa but slightly more oblong, rostrum a little shorter and broader (L/W ratio 1.4 instead of 1.6); eyes less evenly convex (more depressed in front); legs stouter (protibia not much longer than pronotum), male metatibia more robust without trace of terminal spur; internal rim of tibial face flat and bordered by 4–5 flat, thickened, blunt setae or spines, leaving a small open middle space. Aedeagus (fig. 12 C–D) relatively long and characteristic, ending in broad ly tapering, slightly bisinuate apical plate with a well developed median keel at blunt apex, anvil-like in profile; internal sac shorter but with equivalent fields of sclerotized denticles and teeth. Hemisternites with short subapical styli, not widely distant (compare figs. 12 F, G); plate of sternite VIII larger (fig. 16 A). Etymology. The subspecific epithet (unarmed) refers to the absence of an apical lobe on the male metatibia. Remarks. Females of L. inermis and L. hupalupa are difficult to distinguish from each other unless the ovipositor is examined. Only the males of the latter species bear the characteristic apical metatibial lobe, which is absent in L. inermis. However, if this lobe is broken or abraded, also the males can only be distinguished by their genitalia, the apex of the median lobe being narrowly attenuated in L. hupalupa but broad, narrowing apicad and always with a well developed median keel in L. inermis (fig. 16 A). Both species can be easily distinguished from other similar species by the conspicuous, narrow pronotal constriction or collar and by the absence of hairs or scales on the elytra. Material examined. Holotype: Tagamiche-S, 930 m (UTM = 28 R 0 2785788 3109002), 3 - 1-2005, leg. A. Machado, 1 ɗ (TFMC, reg. CO- 15518). Paratypes: s ame data, 6 exx. (AMC); same locality, 7-12 - 2002, leg. R.

A. Machado, 3 exx. (AMC). Other specimens: El Cedro, 850 m (under stone), 5 - 5-1981, leg. A. Machado, 1 ex. (AMC). Distribution and ecology. This species seems to be restricted to high altitudes in the south-eastern part of La Gomera. It was collected at night, feeding on Cistus monspeliensis mixed in bush vegetation with Kleinia, Echium and Euphorbia or, on cliffs, with Pericalis or Argyranthemum. One specimen was found beneath stones in the forest area of El Cedro, but the exact habitat is not recorded.Published as part of Machado, Antonio, 2007, New species of Laparocerus Schönherr, 1834 from La Gomera, Canary Islands (Coleoptera, Curculionidae, Entiminae), pp. 1-38 in Zootaxa 1643 on pages 18-19, DOI: 10.5281/zenodo.17969

Antennal appendage with a short, undivided, distally smooth lateral branch; dorsal clypeal process as a non-sclerotized small tubercle, hardly exceeding level of fused basal part of antennal appendages; frontal clypeal process as a well developed dorsoventrally flattened plate; ventral clypeal process as typical of the genus; distal segment of antenna with a short prominent ventrolateral crest at a level very close to the point of maximum curvature; basal part of penis ending into 2 mucronated, divergent “lips”. Female. 10 th and 11 th thoracic somites widened, with the 11 th somite having one pair of dorsolateral swellings. Cyst. Spherical, with moderate high crests delimiting irregular polygonal cells, without superficial hairs. Description. Adult Male. General. Body of living specimens unpigmented, ivory or milky white coloured, sclerotized parts golden brown. Head with nuchal organ widely elliptic, sometimes almost subrectangular, main axis transversal. Antennule more than twice as long as the compound eye plus peduncle, longer than the basal segment of antenna (Figs 2 A, C; 7 B), with 3 long subdistal setae and 6 distal aesthetascs (as in Fig. 10 A). Antennae sclerotized, elliptic (sometimes almost circular) in outline (Figs 1 A, B; 2 A; 7 C), slightly longer than wide, extending up to the posterior limit of 3 rd thoracic somite (Fig. 7 B). Basal segment longer than distal segment of antenna (ratio: 1.1–1.3); proximal 50–60 % of basal segment fused, forming the clypeus. Clypeus with 3 pairs of processes (Fig. 1 A, B): dorsal (dp), frontal (fp) and ventral (vp). Dorsal processes, located at base of frontal processes as small non-sclerotized rounded tubercles pointing to the front, provided dorsally with a cluster of small setae; they laterally border the incompletely fused proximal part of the antennal appendages, hardly projecting beyond it (Figs 1 A; 2 A, C; 7 C, D, G). Frontal processes partly hidden under the antennal appendages (Figs 2 A; 7 A); each as a subquadrangular plate originating from middle of dorsal extension of clypeus and protruding approximately the same length beyond its frontal end; flattened dorsoventrally, triangular in lateral view and arched dorsally to lateral, mucronated distal angle; medial distal angle a roundish right or somewhat obtuse angle, very close to that of its pair; frontal border with a triangular incision, closer to its lateral side; lateral part of frontal border can extend beyond medial one (Figs 1 A; 2 A; 7 A, C, D, G). Ventral processes arising close to the medial part of frontal border of clypeus, each as a dorsoventrally flattened, subtrapezoidal plate, distal margin longer, medial distal angle right to somewhat acute, widened dorsally into a more or less prominent conical or roundish outgrowth; lateral distal angle prolonged into a digitiform outgrowth extending to or surpassing the medial distal end of the basal segment of antenna; a subconical apophysis on its dorsal side, near its frontal oblique border, approximately midway to distal angles; convex proximal surface of apophysis squamous; frontal flat smooth surface of apophysis approximately transverse, oblique in relation to frontal edge of the plate (Figs 1 A, B; 2 A, B; 7 C, D, E, F). Distal segments of antennae outlining a semicircle, each with the maximum point of curvature at 25– 33 % from its proximal end, approximately cylindrical in cross-section diminishing in diameter to the distal end, which is ventrally scooped, spoon-shaped (Figs 1 A, B; 2 A, B, C; 7 C, D, F). Distal segment of antenna with 3 ridges: the most proximal ridge (pr), short and prominent, developing ventrolaterally, at the point of maximum curvature or, more commonly, immediately distal to that point; shaped like a deformed semicircle, flattened (higher) proximally or, less commonly, subtriangular with proximal rounded angle and rounded distal side; concave ventrally and convex dorsally (Figs 1 A, B; 2 A, B, C; 7 A, C, D, F); an intermediate ventral ridge (ir) developing slightly to medial side from the proximal end of distal ventral “spoon” to the base of the most proximal ridge to which it is connected; shaped as an asymmetrical arc of a circle, highest proximally, distal edge somewhat sinuous and flattened (Figs 1 B; 2 B, C; 7 A, B, F); a subdistal ridge (sr) arising ventromedially and developing to dorsomedial side, typically higher distally, subtrapezoidal or subtriangular with roundish free angle and sides or shaped as an asymmetrical arc of a circle, forming a bifurcated extremity with the distal tip of antenna (Figs 1 A, B; 2 A, B; 7 A, C, D). Base of distal segment of antenna with a medial small, unapparent, hyaline lamella (hl), subrectangular, transverse, sometimes prolonged laterally to form a pointed or rounded beak (Figs 1 A; 2 A; 7 C, D). Antennal appendages—also called appendix verticalis in Daday (1910) and Gauthier (1928 b), processus serriformis in Brtek (1972) and Thiéry (1986 b) or antennal serrated laminar outgrowths in Thiéry & Brtek (1984) —up to twice the length of antennae, arising from the middle of the base of clypeus as an incompletely fused pair of sclerotized cylindroid branches, partially hiding the frontal processes (Fig. 2 A, C); approximately at the level of half length of these processes, the incomplete fusion of the two antennal appendages ends, and continue squeezed against each other before getting separated like the teeth of a fork closer to the distal edge of frontal processes (Figs 2 A; 7 A, G); from this separation point, each antennal appendage, sclerotized and cylindroid proximally, become progressively wider, flatter and softer, losing the sclerotized appearance before dividing into a very short lateral branch and a long medial branch at 20–33 % of the extension of its free portion (Fig. 2 A, C, D). Antennal appendages, when in resting position, stay wrapped under themselves, enclosed by the antennae (Fig. 7 A, B); lateral branch digitiform, 14–20 % as long as medial branch; medial branch ribbon-like, dorsoventrally flattened, gradually tapering toward a distal, rounded triangular end. Undivided basal part of the free portion of antennal appendage with a longitudinal ventral row of long sclerotized spines standing perpendicular to the appendage surface, rarely bent to medial side; spines getting shorter and softer distally to the base of lateral branch or even until the middle of its length, still forming a single row, or a wider band of short, soft, rounded conical papillae; distal ventromedial edge of undivided basal part of the free portion of antennal appendage and ventromedial edge of medial branch with a row of short, soft, rounded conical papillae becoming small sclerotized spines toward the distal end; ventral side of medial branch ornamented with short, soft, rounded conical or spine-like papillae, distal end normally with one sclerotized spine; ventrolateral edge of medial branch with more or less sclerotized spines, normally getting shorter toward its distal end; marginal spines of distal part of medial branch (ventromedial, distal and ventrolateral) approximately of same size (Figs 2 A, C, D; 7 H). Labrum very similar to that of Branchipus cortesi Alonso & Jaume; distal lamella widest subdistally, ending in a rounded acute angle (Figs 2 E, F; 8 A). Mandibles as in Fig. 9, similar to those described for the genus (Mura, 1996). First maxillae, each with 22–24 setae and a posterior ventral spine (Fig. 2 G); basal part of setae half length the distal part, or a little less; posterior side of the basal part of setae completely covered with spines arranged in two rows; transitional area between basal and distal part of setae also completely covered by spines (Fig. 2 I); anterior side of distal part of setae ornamented with two rows of fine setulae (Fig. 2 I), incorporating in the distal half more spaced spines (Fig. 2 J); posterior ventral spine small (around 0.1 times the shortest setae), devoid of setulae, divided into two subequal parts, and ending in a fine point; a field of fine setulae appear near the base of the posterior ventral spine (Fig. 2 G, H). Second maxillae ventrally directed, swollen, truncated distally; proximal part widely covered with fine setulae, with a small spine and 2–3 anterior setulose setae; distal part covered with scattered small setulae, and a ventral distal long plumose seta with basal crown of pectinate scales (Fig. 2 K). Thorax fusiform, wider at 6 th or 7 th somite level. Eleventh thoracic somite with lateral lobes at the posterior 20– 25 % of its length. Dorsally, each thoracic somite carries one pair of warty outgrowths with a central sensilla, similarly to other anostracan species (Linder, 1941). Thoracopods are homonomous, though T 4 –T 7 —less commonly T 8 —are the biggest ones (Fig. 3 A). Praepipodite undivided, ear-shaped in the first ten thoracopods, about twice as long as high, with 2 spaced denticles on lateral edge and denticulate distal edge (Fig. 1 C; 3 A, C, F); praepipodite of T 11 as a basally truncated ellipsis, oblique, directed to the distal part of thoracopod, about 1.5 times as long as high, edge almost smooth except for 2 denticles on lateral margin (Fig. 4 A). Epipodite tending to be longer in relation to width (from about 2: 1 to about 3: 1) from anterior to posterior thoracic appendages, digitiform in the first ten thoracopods, margin smooth (Fig. 3 A, C, F); epipodite of T 11 of similar shape but usually narrowing towards distal tip, with a denticle on it (Figs 3 A; 4 A, C); the distal part of its medial edge (much more rarely of lateral edge) may present a few naked or plumose setae (Fig. 4 C): 36.4 % of the examined males (n= 151) have one or both epipodites of T 11 with those setae; this percentage differs from a population to another, ranging from 12.5 % (n= 32) in VF, to 57.1 % (n = 28) in AZ. Exopodite like an asymmetrical truncate orange segment, wider near the base, straighter side lateral, tending to be longer from anterior to posterior thoracic limbs (length of exopodite in relation to length of endopodite, from about 0.8 times at T 1 to about 1.8 times at T 11; length of exopodite in relation to length of the remaining of thoracopod, from about 0.8 times at T 1 to approximately equal at T 11; length of exopodite in relation to length of the whole thoracopod, from about 0.4 times at T 1 to 0.9 times at T 11) (Figs 3 A, C, F; 4 A); provided with a few (5–7) proximal spine-like setae on lateral margin, gradually longer distally; rest of exopodite with marginal plumose setae. Endopodite of T 1 semi-oval (Fig. 3 A, C); endopodite of T 2 elongated semi-oval with a small distomedial subtriangular projection (Figs 3 A; 4 D); endopodite of T 3 –T 4 elongated semi-oval with a pronounced narrow distomedial subtriangular projection (Figs 3 A; 4 E, F; 7 A); endopodite of T 5 –T 10 expanded semi-oval, medial edge straightened with an angulation closer to the 6 th endite, apex provided with a notch (Figs 3 A, F; 4 H); endopodite of T 5 sometimes also with a small narrow distomedial subtriangular projection (Fig. 4 G), intermediate shapes rare but possible; endopodite of T 11 as that of T 5 –T 10, but apex without a notch (Fig. 4 A); endopodite, excluding the subtriangular projection on T 2 –T 4 or T 5, about half length of the whole thoracopod; endopodite of T 1 provided with spine-like setae on medial or distomedial margin and plumose setae on lower margin; endopodites of T 2 –T 4 (also, that of T 5 when it presents a distomedial subtriangular projection) with spine-like setae on medial margin and on distal part of lower margin, plumose setae on proximal part of lower margin and some short, naked spines (3–4) on the subtriangular projection; endopodites of T 5 –T 10 with spine-like setae on distomedial margin and on distal part of lower margin and plumose setae on proximal part of lower margin; endopodite of T 11 with spine-like setae on distomedial margin and plumose setae on lower margin. Endite 1 + 2 elongated with roundish edge bordered by a comb of long filtering setae lacking basal crown of pectinate scales except at T 11, and with the typical anostracan number and location of anterior setae (Linder, 1941). The distal anterior seta, strong, pectinate, with basal crown of pectinate scales. The intermediate anterior seta at T 1–10, very close to the distal one, is very short, bubble-like and naked; at T 11, it is not so close to the distal one, almost half length of it, conical, ending in a stiletto. The most proximal anterior seta at T 1 –T 10, approximately twice as long as the most distal anterior seta, fragile and provided with sparse, short and very fine setulae at both sides; at T 11 it is similar in shape to the intermediate seta, about half length of the most distal anterior seta (Figs 3 D, G; 4 B). Third endite normally 25–33 % as long as endite 1 + 2, with roundish edge bordered by a comb of long filtering setae at T 1 –T 10, with the typical anostracan number and location of anterior setae (Linder, 1941). The more distal anterior seta similar to the more distal anterior seta of endite 1 + 2, about twice its length, and the more proximal one of the same type as the intermediate seta of T 11 endite 1 + 2 (Fig. 3 D, G). T 11 with 3 rd endite globular just a little longer than the 4 th– 6 th endites; filtering comb reduced to 2–4 long setae; anterior setae similar to the corresponding setae at the other thoracopods, the more distal one located near the middle of the endite margin and about 1.5 times as long as the more distal anterior seta of endite 1 + 2; the more proximal one close to endite 1 + 2, a little shorter or as long as the more distal one (Fig. 4 B). Fourth endite conical (rounded conical at T 1; rounded conical to globular at T 11) with 2 spine-like anterior setae and typically 3 (2–3) long plumose posterior setae located distally at the first ten thoracic limbs, and 2–3 located centrally at T 11 (Figs 3 E, H; 4 B). Fifth endite conical or rounded conical, with 2 spine-like anterior setae and typically 2 (1–3) long plumose posterior setae located distally at the first ten thoracic limbs, and normally in the middle of the endite at T 11 (Figs 3 E, H; 4 B). Sixth endite typically conical (sometimes rounded conical) at T 1 –T 10, and rounded conical (sometimes conical or globular) at T 11, with 1 spine-like anterior setae and typically 2 (1–2) long plumose posterior setae located distally (sometimes closer to a central position) at the first 10 thoracic limbs and 1–2 posterior setae located centrally at T 11 (Figs 3 E, H; 4 B). Genital somites. First genital somite usually longer than 11 th thoracic somite and wider than the 2 nd genital somite, both with posterodorsolateral pair of warty outgrowths with a central sensilla (Fig. 5 C). Penes with a pair of symmetrical, ventral basal, dorsoventrally flattened, triangular sclerotized processes typical of the genus (Brendonck, 1995), with lateral margin regularly curved or, when forming an angle, more obtuse than the one described for T. brteki (Thiéry, 1986 b) (Figs 5 A, D; 8 B, C). Basal part of each penis cylindroid, extending posteriorly hardly up to the end of 1 st postgenital somite, about twice as long as the ventral basal triangular process, and with the medial spur typical of the genus at a level just proximal to the distal end of the triangular process; distal end with 2 mucronated “lips”, the lateral “lip” longer than the medial, mucrons divergent (Figs 5 A, D; 8 B). Apical eversible part of penis (Figs 5 E, F; 8 D, E, F) about twice as long as its basal part, extending as far as the end of the 3 th postgenital somite; cylindroid with the distal part wider, lobed, with a transversal proximal constriction (a) at 20–25 % of its length and a conspicuous ridge (carina: b) along most of the non-distal lobed part of the medial side, disrupting the transversal constriction; conspicuous longitudinal medial carina provided with a normally single row of big spines (7–14; n= 48) typically directed to the base of the penis, the more distal the shortest; also medially, one medium or long apical spine (c) in the wider distal part of everted penis; ventral side with one big spine approximately at level of the transversal constriction (d), normally with one (0–2) subdistal spine of variable size (e) and with one long, more distal spine closer to the medial margin (f), proximal in relation to spine c; ventrolateral side typically with one medium or long spine distal to transversal constriction (g) and one or more small spines (usually 2–5) proximal to the wider lobed part of protruded penis, in discrete groups or longitudina

All tibiae unarmed; metatibia at apex normal, without terminal lobe. Last ventrite apically rounded. Sternite VIII as in fig. 17 C, spermatheca as in fig. 18 J, with short and straight gland lobe. Etymology. The specific epithet is a noun in apposition and the Guanche name of one of the four aboriginal districts of La Gomera (Hermigua – Agulo), where the species was discovered. Remarks. Laparocerus mulagua is easy to distinguish from other Laparocerus species on La Gomera due to its moderate size, protruding rounded eyes, hairy elytra and the male protibia not curved or emarginate. Long, thin, protruding hairs over the entire elytra are present also in L. lepidopterus Wollaston, 1864 and L. inflatus Wollaston, 1865, but these species are much larger (> 8 mm) and show quite flattened eyes or exceedingly prominent shoulders, respectively. More similar in appearance is Laparocerus bacalladoi Machado, 2005, from Tenerife, of similar size and with hairy elytra but with femora fringed with very long hairs, an almost clavate (not clearly capitate) more robust scape and no protruding lobe in the inner angle of the male metatibial apex, as is characteristic of L. mulagua. According to unpublished molecular data, it belongs to the group of L. lepidopterus. Material examined. Holotype: La Gomera: Playa de Hermigua, 10 m (UTM = 28 R 0 28660 311880), 7- 12 - 2002, leg. A.

L. mulagua is endemic to La Gomera, where it occurs at low altitude at least in the north-east windward sector of the island but is presumably more widely distributed (one locality confirmed on the leeside). It has been collected at night in coastal and Euphorbia- dominated vegetation, feeding on several scrubby plant species: Shizogyne sericea, Rumex lunaria, Artemisia thuscula, Launaea arborescens, Argyranthemum frutescens, Kleinia neerifolia, Astydamia latifolia, Beta maritima and the rare endemic Convolvulus subauriculatus, which was heavily attacked. Apparently it is a polyphagous species active in winter and spring.Published as part of Machado, Antonio, 2007, New species of Laparocerus Schönherr, 1834 from La Gomera, Canary Islands (Coleoptera, Curculionidae, Entiminae), pp. 1-38 in Zootaxa 1643 on pages 25-29, DOI: 10.5281/zenodo.17969

This species is dedicated to Adrien Roudier (1913–2000), French specialist in Curculionidae who contributed much to the knowledge of Laparocerus of the Canary Islands and Madeira. Remarks. Laparocerus roudieri is easily distinguished from the other Laparocerus species of La Gomera by its small size (<5 mm), fairly rounded appearance (especially in the females), shiny, dark integument with less distinct vestiture of scales and devoid of additional setae and, particularly, by the small, prominent, almost hemispherical eyes. Specimens from coastal vegetation at Tamargada and Playa de Hermigua have rounded shoulders in both sexes but show no other consistent differences. Material examined.

Laparocerus roudieri is endemic to La Gomera, where it occurs in the northern part of the island at low altitudes (10-400 m) in natural scrub vegetation as well as on weeds in agricultural land or along roadsides. The type series was collected on Rubia fruticosa and Ferula linkii and the other specimens on Argyranthemum fruticosum, Shizogyne sericea, Mercurialis annua, Bidens pilosa, Artemisia thuscula, Rubus ulmifolius and Sonchus sp. It is apparently a fairly polyphagous, nocturnal species active in winter.Published as part of Machado, Antonio, 2007, New species of Laparocerus Schönherr, 1834 from La Gomera, Canary Islands (Coleoptera, Curculionidae, Entiminae), pp. 1-38 in Zootaxa 1643 on pages 22-23, DOI: 10.5281/zenodo.17969
