No full textCyclocephala berti Delgado, 1992 Material Examined. Two males and five females labeled: " MÉXICO: Veracruz, Zongolica, La Quinta, Amatitla. 29-30-V-2011. Luz mercurial. Bosque mesófilo de montaña. Alt. 1250 m, E. Mora, L. Delgado y L. Lara cols". One female with same data, except 31-VI-2011. One male with same data, except 31-VII-2011. The specimens are deposited in the following collections: University of Nebraska State Museum (Nebraska, USA) 1 ♂ 1♀; Instituto de Ecología, A. C. (Xalapa, México) 2♀; L. Delgado Collection (Mexico City) 1 ♂ 1♀; and E. Mora-Aguilar Collection (Xalapa, México) 1 ♂ 2♀. This species was described based on only one male specimen from the H. & A. Howden collection (now in Canadian Museum of Nature, Ottawa, Canada). The specimen was collected in the Los Tuxtlas region on the southeastern slope of the Volcán de San Martín, Veracruz, Mexico. Recently, nine specimens were collected at the Sierra de Zongolica, Veracruz. Male specimens agree with the description of C. berti, except for their larger size (length 13.7–16.8 mm, width across the humeri 6.5–7.3 mm), head completely covered with long and erect setae, and each elytron with 3 or 4 diffuse spots. Female specimens collected are similar to males except in the dimorphic characters, and are different from other species of Cyclocephala. Description of the previously unknown female of C. berti is as follows: Total length 13.1–14.8 mm, width across the humeri 6.2–6.7 mm. Similar to male except in the following respects: Head and pronotum glabrous. Each elytron with 3–4 small, fuscous spots. Elytra and scutellum glabrous, except for the apex and posterior lateral third of elytra with small, sparse setae. Epipleuron expanded at level of metacoxa to abdominal sternites 2–3, with small, rounded, obtuse tooth between abdominal sternites 2–3. Pygidium almost flat, glabrous, except with small, erect setae on the base. Protibiae with basal tooth normal, teeth equidistant. Protarsus not enlarged, claws simple. Metatarsi slightly longer than metatibia.Published as part of Mora-Aguilar, Eder F. & Delgado, Leonardo, 2012, A New Species of Cyclocephala Dejean (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) from the Cloud Forests of Southeastern Mexico and Description of the Female of Cyclocephala berti Delgado, pp. 139-142 in The Coleopterists Bulletin 66 (2) on page 142, DOI: 10.1649/072.066.0209, http://zenodo.org/record/489314

Description. Length 5.0–6.0 mm (Fig. 1), mean length slightly longer in females (5.3 mm) than in males (5.2 mm). Brachypterous. Blackish brown body with faintly shiny discal areas on the pronotum and elytra. Margins of pronotum and elytra paler, appendages testaceous. Integument in general microreticulated. Head: Wider (0.98 mm) than long (0.88 mm). Microsculpture well-developed around eyes and at base, usually very weakened or absent elsehwere on head. Antennae and labium without special peculiarities within the genus. Cephalic setae composed of 3 labral pairs, 1 clypeal pair and 1 ocular pair. Cephalic appendages testaceous, with antennae darkened from the distal end of 3 rd antennomere to last antennomere. Pronotum: Transverse, wider (1.8 mm) than long (1.1 mm), anterior margin wider than basal margin and reaching maximum width in anterior half of pronotum. Lateral edge regularly arched and posterior angles rounded. Well-defined basal pits, oval shaped, with variable depth and visible reticulation inside. Elytra: Wide (2.2 mm), maximum width in posterior half. Striae well-marked, relatively wide. Third elytral interval with a discal pore in posterior half on medial side. Umbilicate series variable, between 11 and 14 punctures (4–5, 1, 6–8). Elytral disc usually with a weak greenish reflection and suture zone and lateral margins often reddish. Legs: Similar to other species of the genus. Male pro- and mesotarsi moderately dilated, ventral side densely covered in vestiture. Male genitalia: As in Fig. 2. Aedeagus relatively short, slightly raised at end and apex slightly thickened. Inner sac of aedeagus with 5 welldifferentiated pieces: a very long spine distally, 2 triangular pieces of more moderate size, and 2 squamous pieces arranged symmetrically. The morphology of the male genitalia presents a set of characters that are clearly different from other known species of the genus. Taxonomic Considerations. Starting from the groups established by Moret (2000, 2005) (Table 1), P. amicorum matches the characteristics of the variipes species-group. It is a brachypterous species of medium size and with weak or no metallic reflection. The pronotum of P. amicorum is transverse, with arched sides and rounded posterior angles. Finally, the male mesotarsi are moderately dilated, and the presence of setae in the third elytral interval is compatible with the characteristics of the variipes species-group. Within the variipes species-group, P. amicorum presents a closer affinity with Pelmatellus caerulescens Moret, 2005, Pelmatellus variipes Bates, 1891, and Pelmatellus obesus Moret, 2000, due to the presence of punctures in the third elytral interval. However, the different external morphology of the aedeagus and the different configuration of the internal parts distinguish P. amicorum from them (Moret 2000, 2005). Ecology. Pelmatellus is characterized by great ecological plasticity, which allows its species to occur in various ecosystems. Pelmatellus amicorum is commonly encountered between 3,815 and 4,280 m elevation. It inhabits xerophytic scrublands of the Peruvian Altiplano, although it has also been collected in hygrophilic conditions on the shores of lakes and streams or even in cultivated quinoa (Chenopodium quinoa Willd., Amaranthaceae) and potato (Solanum tuberosum L., Solanaceae). Etymology. This species is dedicated to our friends (amicorum) Julio Sosa, Edwin Velásquez, and Luis Luque, to thank them for their sampling work during many expeditions. Distribution. Pelmatellus amicorum occurs in southern Peru (Map 1). Very little is known about the distribution of Pelmatellus in Peru. Only the general presence of Pelmatellus columbianus (Reiche, 1842) in Peru (Moret 2000, 2005; Perrault 1993), as well as the possible presence of Pelmatellus gracilis Moret, 2000, in the north (Moret 2000, 2005), Pelmatellus cycnus Moret, 2000 (Moret 2000), and Pelmatellus lojanus Moret, 2000 (Moret 2000), are known or speculated. Moreover, some authors, e.g., Erwin et al. (2015), have pointed out the existence of up to 12 new taxa not yet described. In any case, although P. amicorum is tentatively assigned to the variipes species-group, it should not be forgotten that the knowledge of the subgenus at the continental level is still little known. Undoubtedly, additional sampling together with the description of new taxa could affect the a subgeneric or species-group classification of Pelmatellus.Published as part of Delgado, Pedro & Ruiz-Tapiador, Ildefonso, 2020, Pelmatellus Amicorum Delgado And Ruiz-Tapiador (Coleoptera: Carabidae), A New Species From The Andean Altiplano Of Peru, pp. 71-75 in The Coleopterists Bulletin 74 (1) on pages 72-74, DOI: 10.1649/0010-065X-74.1.71, http://zenodo.org/record/374692

Allotype female labeled: ‘‘ GUATEMALA, Guatemala, Ciudad Capital, Zona 18, Alameda 1, 13-V-1989, alumbrado público 9: 30 p. m. E. Cano col’ ’. Paratypes labeled: Same data as allotype (2 OiOi); ‘‘ GUATEMALA: Guatemala, Ciudad de Guatemala. 17-IX-1985, M. Zepeda col.’’ (1♀); same data except: ‘‘ V-1986, L. Rodriguez col.’’ (1 Oi); same data except: ‘‘ 15-Jun-1983, R. Pérez col.’’ (1♀); ‘‘ GUATEMALA, Sacatepéquez, San Lucas, 12-IX-1985, C. Granados col.’’ (1 Oi, 1♀). The holotype and allotype are deposited in the entomological collection of the Universidad del Valle de Guatemala. Paratypes are deposited in the following collections: University of Nebraska State Museum (Lincoln, Nebraska, U.S.A.), M. A. Morón (Xalapa, Veracruz, Mexico), L. Delgado (Mexico City), and A. Bitar (Mexico City). 213 Description. Holotype male. Total body length: 25.8 mm; maximum elytral width 13.8 mm. Head and pronotum shiny black; elytra, legs and ventral region reddish black. Head: Apex of clypeus bilobed and reflexed, lateral margins slightly concave, frons with a short, vertical, upright horn, horn flattened anteroposteriorly. Pronotum: Pronotal declivity vertical, not excavated, occupying apical third; pronotal process absent (Fig. 1); pronotum completely margined, anterior corners at right angles, lateral margins almost equally curved; pronotal cavity densely punctate, punctures becoming sparser towards posterior half, disc of pronotum with micropunctures. Elytra: Sutural stria impressed for entire length; surface smooth, with only some small, scarcely punctuate furrows. Venter: Prosternal process moderately short and with dense setae, projected backward. Pygidium: Surface regularly convex, basal region and sides finely rugose, remaining surface with small, sparse punctures. Legs: Apex of metatibia with three rounded teeth, without incisions between them. Genitalia: Parameres moderately large, apex slightly widened, with large and dense setae along sides and at apex (Figs. 3–4). Allotype female. Total body length 24.6 mm; maximum elytral width 13.4 mm. Similar to holotype except for the following characters: Head with small tubercule between eyes. Pronotum regularly convex, disc with micropunctures, anterior angles rugopunctate. Elytra with furrows more pronounced. Pygidium wider, convex, with small punctures; last visible sternite not emarginate at apex. Protibial teeth acute. Metatibia with teeth smaller, shorter spur preapically widened. Variation (4 males, 3 females). Male paratypes with lengths of 23.0– 24.3 mm; females with lengths of 22.1–23.1 mm. Males with maximum elytral widths of 13.6–13.7 mm; maximum female elytral widths 12.2–13.9 mm. The variation in male punctation is minimal, and in the smallest female specimen (from the region of Guatemala City) the elytral striae and punctation are more marked. Type Locality. San José Pinula, Guatemala, Guatemala. Etymology. Named for Guatemala, the country where this species was discovered, combined with the suffix ‘‘-ensis’’, indicating ‘‘belonging to’’. Taxonomic Remarks. Xyloryctes guatemalensis can be distinguished from other species of the genus by the following combination of characters: elytra with distinct sutural striae; apex of metatibiae with three rounded teeth, without incisions between them; males with cephalic horn flattened anteroposteriorly; pronotal declivity vertical, not excavated, occupying apical third of pronotum; pronotal process absent (Fig. 1); and shape of the parameres distinctive (Figs. 3– 4). Females have the pygidium almost glabrous and convex, and the shorter spur of the metatibia is preapically widened. Males of X. guatemalensis are similar to those of Xyloryctes howdenorum Delgado and Nájera, but they can be distinguished by the following differences: cephalic horn flattened anteroposteriorly in X. guatemalensis (cylindrical in X. howdenorum); pronotal declivity vertical in X. guatemalensis (oblique in X. howdenorum) (Figs. 1–2); and parameres without a lateral tooth in X. guatemalensis (with a lateral tooth in X. howdenorum) (Figs. 3–6). Females of X. guatemalensis are similar to those of Xyloryctes teuthras Bates, except for the following characters: body length is generally less than 24.0 mm in X. guatemalensis (longer than 24.0 mm in X. teuthras); pygidium convex, base almost glabrous in X. guatemalensis (slightly convex to flattened and with distinct setae at the base in X. teuthras). Distribution. Xyloryctes guatemalensis is known from three localities situated in the southern region of Guatemala. The Guatemala City (1,520 m) and the San José Pinula (1,750 m) localities are located in the Department of Guatemala, and the San Lucas locality (2,090 m) is located in the Department of Sacatepéquez. This new species inhabits regions with premontane and montane wet forests (such as oak and pine-oak forests) (sensu Campbell and Lamar 1989).Published as part of Bitar, Alberto & Delgado, Leonardo, 2009, A New Species of Xyloryctes Hope (Scarabaeidae: Dynastinae) from Guatemala, with a Key to the Species, pp. 213-217 in The Coleopterists Bulletin 63 (2) on pages 213-215, DOI: 10.1649/1144.
Recent Results From the EU POF-PLUS Project: Multi-Gigabit Transmission Over 1 mm Core Diameter Plastic Optical Fibers
No full textRecent activity to achieve multi-gigabit transmission over 1 mm core diameter graded-index and step-index plastic optical fibers for distances up to 50 meters is reported in this paper. By employing a simple intensity-modulated direct-detection system with pulse amplitude or digital multi-tone modulation techniques, low-cost transceivers and easy to install large-core POFs, it is demonstrated that multi-gigabit transmission up to 10 Gbit/s over 1-mm core diameter POF infrastructure is feasible. The results presented in this paper were obtained in the EU FP7 POF-PLUS project, which focused on applications in different scenarios, such as in next-generation in-building residential networks and in datacom applications
Memory, Silence, and Democracy in Spain: Federico García Lorca, the Spanish Civil War, and the Law of Historical Memory
No full textWhat does it mean to unearth the dead? What is contemporary society’s responsibility to the disappeared? How do we live with the ghosts of history? In the midst of the search for the body of Federico García Lorca in 2009, Emilio Silva, cofounder and president of Spain’s Association for the Recovery of Historical Memory (ARMH)—a national organization assisting in the location and exhumation of the graves of Spain’s desaparecidos, or disappeared, during the Civil War and its aftermath—wrote of “the silent bones of Federico García Lorca and the skeleton of our democracy.” This essay traces the ways in which the remains of one of Europe’s most resonant twentieth-century dramatists haunt contemporary Spain. In mapping the wider ideological framework in which his work has been produced in Spain, it engages with the politics of a statesanctioned “official” history that has shaped his appropriation by the nation-state. Using the search for Lorca’s corpse in 2009 as a central focus, it examines how the exhumation of mass graves undertaken in twenty-first-century Spain can be viewed as a move toward a more nuanced understanding both of the events of the past and the fissures of the present in a country where issues of justice have been compromised for too long by a culture of silence

Lateral margins slightly arched through their length, subrectilinear posteriorly, gently sinuate before the posterior angles, which are obtuse and prominent; anterior angles are not projected forwards; basal peduncle prominent; median sulcus and basal impressions softly marked. Two lateral setae at each side, the anterior one just before the widest point, the posterior one before the posterior angle. Microsculpture more noticeable near the lateral margins and progressively less marked toward the disc region. Elytra ovoidal and convex (EW / EL = 0.70-0.76), fully covered by microreticulation; lateral groove wide and flattened. Shoulder region evident marked. Internal striae of elytra weakly marked, absent in the apical region; external striae not visible; without trace of basal striola. Apex of elytra softly curved, almost substraight. Scutellar pore clearly marked. Two discal pores present, the first one located in the basal fifth of the total length and the second, just behind the half of the elytra. The umbilicate series is regular and corresponds to the usual model for the genus. External pore of the apical group absent. Legs short and slim; light testaceous, with femora slightly darker proximally. Protibial sulcus complete but superficial, straight metatibiae. First two protarsomeres asymmetrically dilated in males. Aedeagus (fig 4) strongly arched, with an oblique bulb base, lacking sagittal carina. Apex of median lobe slightly arched downwards, obtuse, progressively attenuated and with a bottleneck before the extreme, which is ovoid. Internal sac without copulatory pieces, only with small internal scales in distal position. Parameres with four setae at their distal ends. MAP 1. Geographical setting of genus Oxytrechus in Peru 1) O. cyathiderus, 2) O. gitzeni, 3) O. paredesi, 4) O. juani n. sp., 5) O. alexei n.sp. Differential diagnosis. The structure of aedeagus in O. alexei n. sp. shows clear differences with the aedeagi of the other Peruvian species. It is distinguishable from O. paredesi, O. gitzeni and O. juani n. sp. by the shape of the apex of aedeagus, clearly different. Moreover, O. paredesi, O. gitzeni and O. juani n. sp. show copulatory pieces in the internal sac, not observed in O. alexei n. sp. In the case of O. cyathiderus the general structure of aedeagus is more akin to that of O. alexei n. sp. but in the former, aedeagus is long and barely curved ventrally, while in O. alexei n. sp. the ventral curve is much more pronounced and, overall, the aedeagus is shorter. Within the other species of the genus, only the species described from Colombia, O. silvanus Mateu, 1991, shows an aedeagus with a general morphology similar to O. alexei n sp. However, in the case of O. silvanus, the narrowing of the distal extreme of the median lobe is much more marked than in O. alexei n. sp., and O. silvanus has a sagittal carina in the base of the bulb, absent in O. alexei n. sp. Etymology. This species is named after Alex Delgado Sosa as a sign of gratitude for his effort and perseverance. Ecology. Currently, O. juani n. sp. and O. alexei n. sp. are only known from their type localities. They seem to be highly adapted to the conditions of the agroecological area of humid Puna that occur in Carabaya mountain range, characterized by high elevation, very low temperatures, annual rainfall between 800–1000 mm and scarce vegetation, mainly represented by Stipa ichu along other grasses (Poaceae) such as Aciachme pulvinata and Antochloa lepidula.Published as part of Delgado, Pedro & Ruiz-Tapiador, Ildefonso, 2019, Two new species of Oxytrechus Jeannel, 1927 (Coleoptera, Carabidae, Trechini) from Peru in Zootaxa 4565 (1), DOI: 10.11646/zootaxa.4565.1.6, http://zenodo.org/record/258966

A. QuirozRocha col." Three male paratypes deposited at CZUG and IEXA. Two paratypes labeled: " MÉXICO: Jalisco, Mascota, Cerro La Mona, 5 VI 2004, Alt. 1,433 m, bosque de encinopino, 20 º 27 ' 44.8 '' N 104 º 45 ' 2.2 '' W, bajo musgo, G. A. QuirozRocha col.” (CZUG, IEXA). One paratype labeled: " MÉXICO: Jalisco, Mascota, El Atajo, carr. a San Sebastián del Oeste, BMM, 20 º 38 ' 1.1 ''N, 104 º 51 ' 45 ''W, Alt. 1,413 m, NTP calamar, 5.VI 3.VII. 2004, J.L. NavarreteHeredia and V.H. Gómez" (CZUG). Description. Male, total length 13.7 mm, maximum width (at middle of elytra) 5.8 mm. Body ovalelongate; color dull black on frons, pronotum, most of abdomen and thorax; dull reddishbrown on elytra and middle of abdomen; red on clypeus and legs; surface with small, lanceolate, whitish scales. Clypeus trapezoidal, sides straight, apex bilobed, sides and apex perpendicularly reflexed, surface flat; clypeus and frons densely and coarsely punctate with dense, recumbent scales; vertex sparsely punctate with sparse scales; antennae 9 segmented, club slightly shorter than segments 2–6 combined. Pronotum swollen, semihexagonal, somewhat wider than long, anterior angles acute and posterior angles obtuse; base as wide as base of elytra, base anterior to scutellum fitting in scutellar base; pronotal surface with appressed scales in a pattern more or less longitudinal, forming glabrous areas as follows: along midline, 2 anterolaterad and 2 posterolaterad to midline and at lateral foveae. Scutellum heartshaped with moderately dense, recumbent scales. Elytra longer than wide, elytral surface distinctly shagreened with costae scarcely elevated; elytral intervals with scarce, appressed scales smaller than those of pronotum, scales of first and second intervals coalescing at apical region; humeral umbones obtuse and prominent. Venter covered with scales (at sides), scalelike setae and slender and long setae (at midline). Prosternal process slightly curved, extending almost to apex of procoxae. Abdomen in lateral view strongly concave, first visible abdominal sternite broadly concave at middle; sternites 2–5 distinctly longer at sides than at middle; last abdominal sternite with longitudinal central 1 / 4 produced at apex, with moderately dense, long, yellowish setae, apical margin finely denticulate with narrow membranous border. Pygidium longer than wide, convex in lateral view, surface shagreened, with appressed scales except at basal 2 / 3 of midline, apex with dense, yellowish setae. Femora and tibiae with sparse, short, yellowish setae; tarsi with dense, long, golden setae. Protibiae tridentate with basal tooth small, without internal spur, with ventral keel serrate; meso and metatibiae with 2 short, apical spurs. Pro and metatarsi (minus claws) short and thickened, shorter than respective tibiae; first protarsomere with stout, spinose process on ventrolateral face, second protarsomere with same process but smaller; metatarsi (minus claws) slightly longer than metatibiae, less thickened than pro and mesotarsi, metatarsomeres 3–4 as long as wide. All claws simple; unguitractor plate distinctly produced beyond base of claws. Male genitalia with parameres asymmetrical, short, broadly separated, curved at sides and produced at base (Figs. 1–2). Female. Unknown. Variation in paratypes. Three males, total length 11.2–12.2 mm, maximum width (at middle of elytra) 4.9–5.1 mm. The color on frons and pronotum is slightly shining black and density of setae and scales slightly varies. In other respects the paratypes do not differ significantly from the holotype. Remarks. Ceraspis jaliscoensis is included in the Frey's group 3 based on the presence of scales on the dorsum and venter. C. jaliscoensis is most similar to C. oaxacaensis, C. jaliscoensis is distinguished from other species of this group (except C. oaxacaensis), by the following combination of characters: pronotum not rounded, scales of pronotum and elytra arranged in a longitudinal pattern, claws simple and color of pronotum and elytra black or reddish brown. C. jaliscoensis is separated from C. oaxacaensis by the dorsum that is distinctly shagreened and dull or slightly shining (dorsum with scarce shagreened and shining or slightly dull in C. oaxacaensis); by the color of elytra wholly reddish brown (wholly black or only with the elytral margins reddish brown in C. oaxacaensis); and by the shape of male genitalia with the parameres shorter and produced at the base (Figs. 1–2) (parameres longer and not produced at the base in C. oaxacaensis [Figs. 3–4]). The key of the Mexican species of Ceraspis (Delgado 2001) should be modified as follows to include C. jaliscoensis: 1 Dorsum with vestiture of setae or scalelike setae (acicular shape and longer than wide)....................................................................................................................................... 2 Dorsum with vestiture of scales (spearshaped and broader)........................................ 3 2 Clypeus bilobed; pronotum almost evenly convex ......................... C. centralis (Sharp) Clypeus straight or broadly emarginate; pronotum distinctly elevated........................... ........................................................................................................ C. mexicana Harold 3 Pronotum almost entirely covered with recumbent scales (reclining on the surface), not forming a longitudinal pattern ..................................................... C. velutina (Bates) Pronotum with appressed scales (closely applied to the surface), forming a longitudi nal pattern...................................................................................................................... 4 4 Pronotum and elytra red..................................................................... C. pilatei Harold Pronotum and elytra black or reddish brown................................................................ 5 5 Elytra almost wholly shining black.......................................... C. oaxacaensis Delgado Elytra wholly dull reddish brown ........ C. jaliscoensis Delgado and NavarreteHeredia Distribution. The discovery of C. jaliscoensis extends the distribution of the genus Ceraspis from 18 º 45 ' N to 20 º 27 ' N (Figs. 5–7). The new species is found at the highest altitude of any species of this genus (1,433 m). In México, others species are found below 1,000 m (Delgado et al. 1987). Additionally, the distribution of C. jaliscoensis extends the range more than 670 km west in México (104 º 45 ' W). Three species of Ceraspis are now endemic to México: C. oaxacaensis (Oaxaca), C. velutina (Guerrero), and C. jaliscoensis (Jalisco) (Fig. 5). The remaining nonendemic species occur in southern Mexican states south to Panamá (Figs. 6–7). Bionomics. The adults were collected on grass (1 specimen), under moss (2) and, in a carrion trap baited with squid (1). The carrionbaited trap was probably an accidental capture, since the adults of this genus feed on flowers (Capistrán and Aquino 1992). Etymology. The specific epithet, jaliscoensis, refers to Jalisco, the state where was collected this species.Published as part of Delgado, Leonardo & Navarrete-Heredia, José Luis, 2004, Ceraspis jaliscoensis, a new species from México (Coleoptera: Scarabaeidae: Melolonthinae), pp. 1-7 in Zootaxa 787 on pages 2-5, DOI: 10.5281/zenodo.15824
