DHMECN 14416, adult gravid female, collected in the Machay Reserve of Fundacion EcoMinga, Cerro Mayordomo (1.370204 S, 78.267943 W, 2,970 m), Rio Verde parish, Baños township, Tungurahua province, Republic of Ecuador, on 17 March 2018, by Darwin Recalde, Fausto Recalde, Santiago Recalde, and Jordy Salazar. Paratypes (Figs. 5–8). DHMECN 14549, juvenile, sex undetermined, without differentiation of external and internal sexual characters, collected at the type locality on 19 October 2018, by Fausto Recalde, Santiago Recalde, Darwin Recalde and Jordy Salazar; DHMECN 17554, juvenile sex undetermined, no differentiation of external and internal sexual characters, collected at the type locality on 30 May 2022, by Fausto Recalde, Luis Recalde, and Santiago Recalde. Generic placement. We assign the new species to the genus Hyloscirtus Peters, 1882, defined according to Faivovich et al. (2005) and Rojas-Runjaic et al. (2018), and to the H. larinopygion group (sensu Duellman & Hillis, 1990; Faivovich et al., 2005), according to its phylogenetic position (Fig. 1) and morphological traits such as wide dermal fringes on fingers and toes, hands and legs with large terminal discs and a reduced membrane, adults characterized by a snout vent length>60 mm, and dark overall skin color contrasting with bright color patterns. Diagnosis. Hyloscirtus sethmacfarlanei sp. nov. is a member of the Hyloscirtus larinopygion group as diagnosed by Duellman & Hillis (1990), Faivovich et al. (2005) and Weiens et al. (2005), and differs from other members of the group by the following combination of characters: discs of digits narrow; fleshy calcar present cloacal ornamentation with two thick well-defined parallel paracloacal grooves; a well-defined supracloacal fold reaching the vent; skin surrounding cloaca strongly areolate and granular; anterior border of sphenethmoid not in contact with nasal; nasal not in contact with maxilla; frontoparietals rugose; vomers not in medial contact, and with 12‒13 tooth loci; 54‒56 maxillary tooth loci; 10‒11 premaxillary tooth loci; zygomatic ramus of squamosal slightly longer than otic ramus, and otic ramus not in contact with prootic. The adult female, in its reproductive stage with internal sexual characters defined, is further characterized by black ground color covered with large bright red spots on both the dorsal and ventral surfaces, and red tips on all digits.

Measurements of the paratypes. See Table 2. Osteology of the preserved holotype (Figs. 12–15). Coloma et al. (2012) provide a detailed description of the osteology of the H. larinopygion group. In order to avoid redundancy, in the following we describe only those osteological features of the holotype of H. sethmacfarlanei sp. nov. where we found differences from the other species. Skull (Figs. 11, 12). The anterior border of the sphenethmoid is not in contact with the nasal; the nasal is not in contact with the maxilla; the frontoparietals are rugose; the paired vomers bear 12‒13 tooth loci and are not in contact medially; there are 54‒56 tooth loci on each maxilla and 10‒11 tooth loci on each premaxilla; the zygomatic ramus of the squamosal is slightly longer than the otic ramus, and the latter is not in contact with the prootic. Posteromedial processes of the hyobranchium (Fig. 15). The posteromedial processes of the hyobranchium are paired ossified structures, longer than broad, the anterior portion with triangular “head-like” shape, and a posterior elongated stem. Tadpole. Not known. Advertising call. Not known. Variation (Figs. 5, 6, 10 and 11). Standard measurements from the three collected individuals are shown in Table 2. The three known juveniles (DHMECN 14549, DHMECN 17554, and the uncollected individual) share the distinctive cloacal ornamentation and skin texture of the holotype, but differ from the female holotype as follows: sexual characters not clearly evident (based on the observation of internal anatomy); in life the dorsal surface with irregular marks mustard yellow heavily stippled with black, especially on flanks and lower back (DHMENC 14549), or a variagated yellow-orange pattern (DHMECN 17554); nictitating membrane dotted with mustard yellow on a gray background (DHMENC 14549) or orange on a black background (DHMECN 17554); extremities orange banded (DHMENC 14549) or spotted (DHMECN 17554), on a grayish black to black ground; flanks black with orange reticulations and irregular spots; throat marbled with irregular orange or yellowish patches with orange tones on a grayish black or black ground; belly and ventral surfaces of the extremities grayish black with irregular sparse diffuse light orange or whitish-yellow patches (DHMENC 14549) or solid orange (DHMENC 17554); palms of hands and feet black with diffuse light orange spots. The uncollected juvenile had a mainly yellow dorsal coloration, with diffuse blackish spots scattered on the flanks and hidden surfaces of the arms and between the fingers, whose tips were yellow. The belly is light cream with diffuse blackish spots. We noted rapid temporal chromatic changes in the juvenile individuals, from dull yellow to orange tones. As observed in other members of the Hyloscirtus larinopygion species group, changes in color pattern may be characteristic of different stages of development and related to ontogenic changes (Coloma et al., 2012). The juveniles all shared the same distinctive cloacal ornamentation as the adult (Fig. 10). Comparison with similar species (Figs. 8, 9, Table 3). The black and red pattern of the female of the new species is most similar to the patterns of Hyloscirtus pantostictus (Duellman & Berger, 1982), from extreme northeastern Ecuador, and H. princecharlesi Coloma et al. (2012), from the Pacific slopes of the Andes of northwestern Ecuador. The new species differs from these in having both the dorsal and ventral surfaces spotted with red (vs ventral surface without red spots in H. pantostictus and H. princecharlesi, Fig. 8), the cloacal ornamentation (Fig. 9) consisting of a well-defined supracloacal fold reaching next to the vent and the presence of a paracloacal fold (vs reduced supracloacal fold, without paracloacal fold, not contacting the side of the vent, in H. pantostictus, and supracloacal fold defined, reaching the border of the vent, with paracloacal fold thick, in H. princecharlesi), and strongly areolate skin texture (vs smooth in H. pacha, H. staufferorum , and H. larinopygion). The female of the new species also differs from these two species in having red discs on the tips of all digits (vs yellow discs in H. pantostictus and grayish discs in H. princecharlesi). The new species’ red discs are shared with H. lindae (Duellman & Altig, 1978) from the eastern Andes, but H. lindae does not have red spots on its dorsal surface and does not have a thick supracloacal fold close to the side of the vent (Fig. 9). Juveniles assigned to H. sethmacfarlanei sp. nov. have a pattern similar to those of H. princecharlesi and H. larinopygion (Duellman, 1973) from northwestern slopes of the Andes. They differ from juveniles of both species in having the dorsum mottled and stippled mustard-yellow and black (vs dorsum densely spotted orange-red in H. princecharlesi, and yellowish-brown with distinctive cream bars with black interspaces in H. larinopygion). The supracloacal fold is well-defined and reaches to the vent in H. sethmacfarlanei sp. nov. (vs faintly defined and distant from the side of the vent in H. larinopygion). Hyloscirtus sarampiona (Ruiz-Carranza & Lynch, 1982) from the western slopes of the Colombian Andes has dorsal surfaces orange spotted with pale olive, and further differs from the new species by having hidden areas of the limbs, flanks, palmar, plantar surfaces and discs black. The skull of H. sethmacfarlanei sp. nov. (Figs. 12, 13) is generally consistent with those of the other species of the H. larinopygion group (Coloma et al., 2012). However, there were a few differences between the new species and the species of the group studied by us or by Coloma et al. (2012). In H. sethmacfarlanei sp. nov. and H. ptychodactylus, the sphenethmoid is not in contact with the nasal, whereas these two bones are in contact in H. criptico and in H. staufferorum, they are anteriorly in contact in H. lindae and H. larinopygion, they are in contact along most of their length in H. psarolaimus, they are in contact along their entire length but with still a visible suture in H. pacha, and they are completely fused without a visible suture in H. tapichalaca. In H. sethmacfarlanei sp. nov., H. lindae, H. pacha, and H. larinopygion the nasal is not in contact with the maxilla, whereas it is in contact with the maxilla in H. criptico, H. pantostictus, H. ptychodactylus, H. staufferorum, and H. tapichalaca. The frontoparietals of H. sethmacfarlanei sp. nov. are comparatively more rugose than in other species of the group (Fig. 12). In contrast to H. pantostictus and H. staufferorum, in H. sethmacfarlanei sp. nov., H. criptico, H. lindae, H. pacha, H. psarolaimus, H. ptychodactylus, H. larinopygion, and H. tapichalaca the otic ramus of the squamosal is not in contact with the prootic. In H. sethmacfarlanei sp. nov. the zygomatic ramus of the squamosal is only slightly longer than otic ramus, whereas it is moderately longer than the otic ramus in H. pacha and H. staufferorum, and distinctly longer than the otic ramus in H. criptico, H. lindae, H. pantostictus, H. ptychodactylus, H. larinopygion, and H. tapichalaca. In contrast to H. criptico, H. larinopygion, and H. tapichalaca, in H. sethmacfarlanei sp. nov., H. lindae, H. pantostictus, H. ptychodactylus, and H. staufferorum the vomers are not in medial contact. Hyloscirtus sethmacfarlanei sp. nov. has 12‒13 vomerine tooth loci, 54‒56 tooth loci on each maxilla, and 10‒11 tooth loci on each premaxilla, whereas we counted 14 vomerian tooth loci, 59‒60 maxillary tooth loci, and 11‒12 premaxillary tooth loci in H. lindae, 14 vomerine tooth loci, 52‒59 maxillary tooth loci, and 9 premaxillary tooth loci in H. pacha, 13‒14 vomerine tooth loci, 52‒53 maxillary tooth loci, and 9 premaxillary tooth loci in H. psarolaimus, 11‒12 vomerine tooth loci, 56 maxillary tooth loci, and 12 premaxillary tooth loci in H. larinopygion, and only 5‒6 vomerine tooth loci, 31‒33 maxillary tooth loci, and 5‒6 premaxillary tooth loci in H. tapichalaca. In the new species the posteromedial processes of the hyobranchium possess a triangular shaped anterior portion, and a shorter posterior portion compared with the other species shown in Fig. 14, which have an external round border and an internal spine-like border. In H. lindae, H. psarolaimus and H. pacha, the anterior portions have rounded external and internal borders. In H. tapichalaca it is broad and “shell-like” in its anterior border. There are no relevant differences between the forelimb bones of the new species and those of the other species in the group, with the exception of male specimens of H. tapichalaca, which have a greatly enlarged prepollex (Kizirian, Coloma & Paredes-Recalde, 2003; this study) compared to the other species of the H. larinopygion group. Distribution (Fig. 16). Hyloscirtus sethmacfarlanei sp. nov. is known at the moment only from the type locality in Fundación EcoMinga’ s Machay Reserve, Cerro Mayordomo, 2,970 m altitude, in the eastern cordillera of the central Ecuadorian Andes, in the northern side of the upper Rio Pastaza watershed near the southern border of Llanganates National Park in the province of Tungurahua. Natural history. The type locality consists of dwarf open mossy forest, covered with bryophytes and epiphytes, and saturated with humidity. All four known individuals of this species were found on a single narrow mountain ridge, in bromeliads of the genus Guzmania growing within 60–90 cm above the ground (Fig. 17). The holotype is an adult gravid female with a mass of eggs in early stage of development in March 2018. Adult male, tadpole and advertisement call remain unknown. There is some evidence that the striking coloration of the adult female of H. sethmacfarlanei sp. nov. could be aposematic. The frog’ s discoverer (Darwin Recalde), after briefly handling the frog, noticed an unpleasant tingling sensation down his arm, not restricted to the area which had contacted the frog; the sensation lasted several hours. Fausto Recalde, who had shorter contact with the frog, developed similar but shorter-lasting symptoms; these reactions were not observed after handling the juveniles. During handling of the holotype specimen in the museum, it emitted a white exudation on dorsal surfaces with a distinctive odor similar to diluted contact cement. Additionally, when tissue was taken from the liver, dark blackish-colored blood was observed. The bright yellow uncollected juvenile slept during the day, and when disturbed, it adopted a defensive ball-like position, as observed in other species of the H. larinopygion group (Kizirian, Coloma & Paredes-Recalde, 2003; Bejarano-Muñoz, Perez Lara & Brito Molina, 2015). Thus the juvenile coloration may also advertise distastefulness. Nocturnal surveys done by our team in the habitat of Hyloscirtus sethmacfarlanei sp. nov. revealed three sympatric anuran species: two undescribed Pristimantis species and one species of the Pristimantis buckleyi complex. Conservation Status. All four known individuals are known only from the same few square meters of ridgeline, but the area is poorly studied and inaccessible because of steep topography. We suggest the IUCN category Data Deficient (DD) for this species. Etymology. The specific epithet sethmacfarlanei is a patronym in honor of Seth MacFarlane, American writer, director, producer, actor, artist, musician and conservationist, with an outstanding passion for science, biodiversity and the natural world.Published as part of Reyes-Puig, Juan P., Recalde, Darwin, Recalde, Fausto, Koch, Claudia, Guayasamin, Juan M., Cisneros-Heredia, Diego F., Jost, Lou & Yánez-Muñoz, Mario H., 2022, A spectacular new species of Hyloscirtus (Anura: Hylidae) from the Cordillera de Los Llanganates in the eastern Andes of Ecuador, pp. 1-34 in PeerJ 10 on pages 7-25, DOI: 10.7717/peerj.14066, http://zenodo.org/record/759585
Uma cena de Fausto
No full textO assunto fáustico atravessa a obra de Púchkin. Ainda que o autor não tenha tido contato com a segunda parte da tragédia de Goethe, é possível enxergar inúmeros paralelismos do “fomentador” Fausto, nas palavras de Marshall Berman, em O Cavaleiro de Bronze. Em “Uma cena de Fausto”, Púchkin recorre a alguns motivos da história do homem que vendeu a alma ao diabo, os principais são: o esquecimento e o tédio do homem sem limites. Este que é ampliado na composição de Púchkin, para representar, como é típico do autor, temas estrangeiros tendo em vista necessidades históricas do seu país. Na presente tradução, optou-se por uma versão prosaica da “Cena de Fausto”.The faustian subject runs through Pushkin\u27s work. Even though the author has not had contact with the second part of Goethe\u27s tragedy, it is possible to see countless parallels of “The Developer” Faust, in the words of Marshall Berman, in The Bronze Horseman. In “A scene from Faust”, Pushkin resorts to some motifs from the story of the man who sold his soul to the devil, the main ones being: forgetfulness and the boredom of the man without limits. This one is expanded in Pushkin\u27s composition, to represent, as is typical of the author, foreign themes in view of the historical needs of his country. In the present translation, a prosaic version of the “Scene from Faust” was chosen

Fausto Sozzini, la mortalità d’Adamo e la teologia moderna
No full textFausto Sozzini, Adam's Mortality and Early Modern Theology. In his dispute with Francesco Pucci, Fausto Sozzini argues that man was not created immortal but, being by nature subject to death, he could be made perpetually immune only through divine grace, which was a gift not included in his creation. It has thus been suggested that the Pucci-Sozzini querelle should be read as an expression of the broader debate that opposed the two 'souls' of modern theology, that is the Thomistic and the Augustinian. By reconstructing the late medieval theological debate on the mortality of Adam in the condition of innocence, the Author tries to show that Sozzini's theses are greatly indebted to Duns Scotus' criticisms of Thomas Aquinas
Quality Education and "quality papers"
No full textAttending seminars, Conferences, looking at "television lessons" the author saw many times many people (often Professors) that did not know the matter they were talking about. Nevertheless they write papers, suggest books to students, provide lessons, make consultancy. Visiting Companies the author saw many times many Companies lacking Quality of Management, a huge problem against Quality achievement. To overcome this paramount drawback there is a MUST: Quality Education on Quality for Managers (particularly future Managers, now Students in Higher Education). For Higher Education Institutions, this means that professors MUST teach, in a correct and scientific way, Quality ideas on Quality. To be real Managers, Management need to grow-up their knowledge because experience alone, without theory, teaches nothing what to do to make Quality. For Higher Education Institutions, this means that professors MUST learn Quality ideas on Quality Management, in a correct and scientific way. In the paper, as already done several times, we present some new cases (out of the hundreds known to the author) where professors were acting with disquality. Would that be useful
Does "Peer Review" assure Quality of papers and Education?

Visiting Companies the author saw many times many Companies lacking Quality of Management, a huge problem against Quality achievement. Many people (often Professors) think that Quality in written documents is assured by the "Peer Review Process" carried out by members of "international scientific community", "distinguished colleagues, whose achievements and academic standing is well above …", and that "Quality of teaching" is assured by their "academic standing well above …". To be real Managers, Management need to grow-up their knowledge because experience alone, without theory, teaches nothing what to do to make Quality. For Higher Education Institutions, this means that professors MUST learn Quality ideas on Quality Management, in a correct and scientific way. In the paper, as already done several times, we present some other cases (out of the hundreds known to the author) where professors (and referees, as well) were acting with disquality. Would that be useful? Only God knows it
Ritorno al Pireo. Alcune riflessioni sull'organizzazione urbana e sulla cronologia dell'impianto
No full textIn this paper the author discusses the town plan of Piraeus to shed further light on some aspects he already examined in a previous article (Longo 2008). Starting from the most recent archaeological data that were overlooked in some recent studies, and the literary and epigraphic documentation, the author attempts to capture the essential elements informing the development plan of Hippodamus of Miletus, viz., functionality and the likely pre-existence of the main street axes; the characteristics of the urban grid; a clear demarcation of public and private spaces; and the issue of the location of the two agorai mentioned in literary sources.
In questo contributo l’Autore riprende la discussione sull’urbanistica del Pireo chiarendo e precisando aspetti in parte già affrontati in un precedente articolo (Longo 2008). Partendo dai dati archeologici più recenti, poco valorizzati in alcune sintesi di questi ultimi anni, e dalla documentazione letteraria ed epigrafica, l’Autore cerca di cogliere gli elementi essenziali che sono alla base del progetto urbanistico di Ippodamo di Mileto: funzionalità e probabile preesistenza degli assi viari principali; caratteristiche della griglia urbana; netta delimitazione degli spazi pubblici e privati; cronologia dell’impianto; problema della localizzazione delle due agorai menzionate nelle fonti letterarie
Terpandrean Hypotexts in Aristophanes
No full textStarting from the contest of Aeschylus and Euripides in "Frogs", where the author exploits the divergence between the traditional citharodic code and the innovative poetic-musical trends of his time, in order to set forth his critique of tragic drama by throwing the chosen opposing models into high relief (vv. 1248 ff.), the analysis of Aristophanic songs modelled on Terpander’s nomoi and specially on the orthios (Nu. 595; fr. 62 [= 590?] Kassel-Austin; and possibly three times in fr. 591 Kassel-Austin) consolidates the idea that the playwright developed a definite semantics of the lyrical hypotexts
