RESUMO

We described herein a new Hemigrammus from the río Madre de Dios and rio Mamoré basins in southeastern Peru and Bolivia. The new species possess a color pattern similar to those belonging to the Hemigrammus lunatus species-group, i.e., a broad longitudinal dark stripe across the eye and a conspicuous, narrow dark stripe along the anal-fin basis. It can be easily diagnosed from the species belonging to this group by presenting the combination of the following characters: an oval, horizontally elongated humeral blotch, 6-7 upper branch and 10-12 lower branch gill-rakers, up to five cusps on broader maxillary teeth, and by lacking a midlateral dark stripe. Comments on its putative relationships are provided. Additionally, we updated the geographical distribution of Hemigrammus lunatus and H. machadoi based on an exhaustive survey of material deposited in collections.

RESUMO

Two new monotypic genera of Gyponini from South America are proposed, described and illustrated. Caetana gen. nov., from Brazil and Ecuador, differs from other genera of the tribe by the scutellum strongly inflated; forewing expanded apically and hind wing with long r-m and m-cu. Insolitana gen. nov., from Peru, differs from other genera by the presence of a pair of longitudinal carinae on crown; crown, noto, and clavus punctuated; male sternite VIII (= pregenital sternite) fully covering the subgenital plates; and pygofer with internal dorsoapical process.

RESUMO

The fossorial snake genus Anomalepis Jan 1860 currently comprises four species with distribution restricted to the Neotropics, occurring from Nicaragua to trans-Andean Peru. Species of Anomalepis occur on the mainland from sea level to about 2,700 m elevation in habitats that range from xerophyte vegetation to tropical wet forests (Kofron 1988; McDiarmid et al. 1999; Uetz et al. 2019; Wallach et al. 2014). Kofron (1988) performed a taxonomic review of the genus Anomalepis, recognizing two phenotypic clusters of species: the A. mexicanus Jan 1860 composed exclusively by its nominal form, and the A. aspinosus Taylor 1939 group consisting of the former species, A. colombia Marx 1953 (Fig. 1) and A. flavapices Peters 1957. While Anomalepis aspinosus occurs in xerophytic formation from 500-2700 above sea level (asl hereafter) along the Peruvian Andes (Kofron 1988; McDiarmid et al. 1999; Wallach et al. 2014), and Anomalepis flavapices is found in the coastal rainforest plains of northwestern Ecuador (Kofron 1988; Wallach et al. 2014), Anomalepis mexicanus presents the most widespread distribution amongst its congeners, occurring in northeastern Honduras, Nicaragua, Costa Rica and Panama from sea level to 725 m altitude. Even though this species has previously been recorded for Peru (Kofron, 1988), it seems unlikely that this specimen belongs to A. mexicanus due to its distinct meristic features (see Kofron 1988) and its outlandish record (see Fig. 2). Marx (1953) described Anomalepis colombia based on a single specimen collected in 1946 by Kjell von Sneidern at La Selva (05º25'23N, 74º57'44W; 1700 m asl), municipality of Pueblo Rico, department of Caldas, Colombia. As far as we know, since its original description, no additional specimen of A. colombia has been reported in literature (cf. Kofron 1988; McDiarmid et al. 1999; Wallach et al. 2014).

RESUMO

Larva, subimago, imago and eggs of Guajirolus ektrapeloglossa Flowers 1985 are described based on reared males and females from the type locality in Panama and a reared female from Peru. Structure and development of male genitals testify that the Neotropical taxon Guajirolus/g1 (incl. Chane) does not belong to Labiobaetini Kluge Novikova 2016 and, therefore, is not related to the Afrotropical genus Pseudopannota Waltz McCafferty 1987. At the same time, larvae of Guajirolus have striking similarity with that of Pseudopannota. The existent descriptions of Guajirolus nanus Lugo-Ortiz McCafferty 1995, G. queremba Nieto 2003 and G. flowersi Thomas Dominique (in Thomas, Dominique Orth) 2005 do not contain characters allowing to distinguish them from G. ektrapeloglossa. Thus, new synonymy is proposed: G. ektrapeloglossa (= G. nanus syn. n.; G. queremba syn. n.; G. flowersi syn. n.). Among the characters described as species-specific for Guajirolus rondoni Salles 2007, only the shape of labial palps allows to distinguish it from G. ektrapeloglossa.

RESUMO

The crocodylomorph fauna of the Cenozoic of South America is one of the richest and most diverse in the world. The most diverse group within that fauna is Alligatoroidea, with nearly all of its species belonging to the Caimaninae clade. Many of the fossil alligatoroid species from the Cenozoic of South America were proposed based on very incomplete remains, and as a result their validity requires revision. Two such species are Balanerodus logimus Langston, 1965, from the middle Miocene of Colombia and Peru, and Caiman venezuelensis Fortier Rincón, 2012, from the Pliocene-Pleistocene of Venezuela. This study has performed a thorough review of the taxonomic status of these two alligatoroid species, concluding that B. logimus is a nomen dubium and that Ca. venezuelensis is a junior synonym of the extant species Ca. crocodilus. This review offers a significantly more accurate scenario for alligatoroid diversity in the Cenozoic of South America in different epochs such as the Miocene and Pleistocene. Additionally, the record of Ca. crocodilus from the Pleistocene of Venezuela is the first fossil record that can be assigned to this species.

RESUMO

Two new species of butterflies of the genus Argyrophorus Blanchard (Nymphalidae, Satyrinae)-A. idealis n. sp. and A. rubrostriata n. sp.-are described from the Cordillera Negra in north-central Peru. Both, as indicated by colour patterns, male and female genitalia, are related to Argyrophorus lamna (Thieme) which occurs further east and southwards. The new species occur in open puna grassland at approximately 4000 m. One of them is exceptional because both fore and hindwings are uniform shining silvery, in this respect similar only to the Chilean A. argenteus Blanchard.

RESUMO

We describe a new species of montane pitviper of the genus Bothrops from the Cordillera Oriental of the Central Andes, distributed from southern Peru to central Bolivia. The new species can be distinguished from its congeners by the characteristic combination of a dorsal body color pattern consisting of triangular or subtriangular dark brown dorsal blotches, paired dark brown parallel occipital stripes, a conspicuous dark brown postocular stripe, the presence of canthorostrals in some specimens, prelacunal fused or partially fused with second supralabial, one scale usually separating internasals, rostral trapezoidal, two canthals oval to rounded, similar size or slightly larger than internasals, three or four medial intercanthals, eight to twelve intersupraoculars, intercanthals and intersupraoculars keeled and frequently slightly keeled, supraoculars oval, one to three suboculars, two to three postoculars, loreal subtriangular, two to six prefoveals, subfoveals absent, two or none postfoveals, one or two scales between suboculars and fourth supralabial, seven or eight supralabials, nine or eleven infralabials, 23-25 middorsal scales, 189-195 ventrals in females and 182-190 in males, 48-58 subcaudals in females and 54-63 in males, exceptionally undivided. The new species is apparently restricted to areas within Andean montane forests that are less humid and devoid of large trees.

RESUMO

Walkeriella miraculosa gen. n. et sp. n. (Lepidoptera: Hepialoidea: Hepialidae) is based on two specimens collected from rainforest southwest of Puerto Maldonado, Tambopata, Madre de Dios department, southeastern Peru. The distinct genitalia and wing venation separate this taxon from other genera of Hepialidae although four derived characters states are shared in common with the cibyrine clade. The holotype male is deposited in the collection of the Museo de Historia Natural, Lima, Peru.

RESUMO

The presence in Chile of scarab beetles (Coleoptera: Scarabaeoidea) described originally from Peru and Argentina have been reported previously, as a result of the distributional corridors through passes in the Andes Mountains (Gutiérrez 1947, 1950; Roig-Juñent et al. 2005; Ruiz-Manzanos 2006; Mondaca 2011). The purpose of this paper is to report the presence of Parochodaeus bituberculatus (Erichson, 1847) (Coleoptera: Ochodaeidae: Ochodaeinae: Ochodaeini) and Faargia gentilii (Martínez, 1975) (Coleoptera: Scarabaeidae: Melolonthinae: Tanyproctini) in Chile, expanding the distribution of the second species to the west of the Andes Mountain range. The presence of both species in Chile is not surprising, due to the similarity of habitats in the collection areas with neighboring localities in Peru and Argentina.

RESUMO

Marinoni Martins (1978) proposed Anasillus for a single species, A. crinitus Marinoni Martins, 1978, based on a single male specimen from Peru, and until now, the female remained unknown. Herein, the female of this species is described and illustrated for the first time, and its geographical distribution is expanded to Colombia. Additionally, the geographical distribution of seven species of Cerambycidae is expanded to Colombia: Coleoxestia vittata (Thomson, 1861); Sphallenopsis pilosovittata (Bates, 1872); Aneflus (Protaneflus) minutivestis Chemsak Linsley, 1963; Mallocera amazonica Bates, 1870; Compsibidion charile (Bates, 1870); Alcidion sulphurifer (White, 1855); and Acanthoderes (Acanthoderes) ariasi Chemsak Hovore, 2002.

RESUMO

The Hydroscaphidae ("skiff beetles") is a family of minute aquatic beetles within the suborder Myxophaga comprising four genera: Hydroscapha Le Conte, 1874; Scaphydra Reichardt, 1973; Yara Reichardt Hinton, 1976 and Confossa Short et al., 2015. All genera are found within the Neotropical region, with the exception of Hydroscapha, which is widespread. Representatives of this family have been reported for Venezuela, Brazil, Panama (Short et al. 2015) and Nicaragua (Raudez et al. 2019).

RESUMO

This is the first report of the family Tischeriidae in Colombia. We describe two new species recently discovered in the department of Valle del Cauca in southwestern Colombia: Astrotischeria ochrimaculosa Diskus, Stonis Vargas, sp. nov., and A. colombiana Stonis Vargas, sp. nov. The latter is a leaf miner of Asteraceae, while A. ochrimaculosa is trophically associated with Malvaceae. Astrotischeria colombiana is known only from Colombia, but A. ochrimaculosa is more widely distributed from Colombia to Peru. The new species are illustrated with photographs of their habitats, adults, male and female genitalia, and leaf mines. We comment on the rarity of tischeriids in collections and their current known distribution in the Neotropics.

RESUMO

The spider genus Macrophyes O. Pickard-Cambridge, 1893 includes five species from the Neotropical region (World Spider Catalog 2019). Two species were described from Central America, M. attenuata, the type species, by Pickard-Cambridge (1893), known until now only by the male, and M. elongata by Chickering (1937) know by both sexes. Three other species were described from South America, M. silvae Brescovit, 1992 and M. manati Brescovit, 1993 from Peru, and M. jundiai Brescovit, 1993 from Brazil (Brescovit 1992, 1993). Brescovit (1997) diagnosed this genus from other Anyphaeninae by the cylindrical abdomen, retrolateral margin of the chelicera with prominent distal tooth, close to the claw and by the tibia of the male palp almost twice longer than the cymbium. The females could be confused with Mesilla Simon by the long and cylindrical abdomen, but are distinguished by the epigynum with narrow, sinuous lateral borders and, internally, by the long copulatory ducts (see Brescovit, 1997: figs 146, 150-151).

RESUMO

A new species of trichostrongyloid nematode, Acanthostrongylus secundus is described. It differs from the other species of the genus in the structure of the caudal bursa. Squamasnema amazonica is redescribed correcting the synlophe structure and moving the genus from Heligmonellinae to Pudicinae. Both species were collected in Proechimys simonsi from Peru.
