Recent DNA-based studies have found that the genus Thraupis, as traditionally defined, is polyphyletic, with the Blue-and-yellow Tanager (historically treated as Thraupis bonariensis) being sister to the Fawn-breasted Tanager (Pipraeidea melanonota). As a result, most subsequent classifications lumped both species under a single genus, Pipraeidea. Here I show that both species differ markedly in plumage, morphology, voice, and behavior, each of them being more similar to a distantly related species than to each other...

The genus Caenis Stephens, 1835 is well represented in South America with 24 recorded species (14 in Brazil). Based on additional material from Brazil, we describe for the first time the nymphal and egg stages of C. reissi, and re-describe the eggs of C. cuniana. New distributional records for these species and Caenis elidioi are given, and C. teipunensis (previously described from Venezuela) is reported for the first time from Brazil.

In recent years, a considerable number of pierid butterflies of the genus Delias have been found from Jinmen Islands, where no available hostplants grow, rendering a proof of cross sea water migration of these butterflies. It is suggested here that these butterflies come from nearby continent of eastern China, visiting the islands for nectar acquisition in seasons when nectar is in short supply because they mostly show up in autumn months. Samples obtained during the survey contained two species, namely Delias pasithoe (Linnaeus, 1767) and Delias acalis (Godart, 1819)...

The number of species of Microlepidogaster recently increased considerably, the genus presently comprises six species distributed in the Paraná, São Francisco, and Jequitinhonha river basins. A new species of Microlepidogaster is herein described from the upper Rio São Francisco basin, which can be distinguished from all congeners by having two exclusive features within the genus: skin over swimbladder opening with two to five reduced unperforated platelets, and ventral laminar expansion of coracoid enclosing completely or almost completely the arrector fossa of the pectoral girdle...

We describe a new species of Pseudocalotes from montane forests of the central, western coast of Sumatra. The combination of 3 or 4 interoculabials, slightly enlarged and heavily keeled scales on the lower flanks, a white scapular spot, a relatively long fifth toe, bicarinate lamellae at the base of Toe III, absence of a postrictal modified scale, and three rows of paravertebrals directed dorsally and posteriorly distinguishes the new species from its congeners on Sumatra and Java. Among the new characters defined in this study, counts of subdigital lamellae within the "span of Toe V" proved particularly useful for diagnosing species of Pseudocalotes...

Rhinobatos austini sp. n. is described from the southwestern Indian Ocean based on four specimens collected from the KwaZulu-Natal Province, South Africa and from Mozambique. The new species, with one exception, can be distinguished from all other members of this genus by a prominent teardrop-shaped dark blotch on the ventral surface of its snout. Its closest congener, R. holcorhynchus, also has a prominent teardrop-shaped blotch on its snout, but the new species differs from it by a lack of prominent thorns and tubercles on it dorsal disc surface and a very striking dorsal surface colour pattern of paired spots, some forming darker transverse bands across its back...

Species of Belostoma in the dentatum and subspinosum groups are large and closely related, and have been combined by some authors into a single group, the dentatum group, comprising 15 species. This group is recognized by the scutellum reaching the nodal line and the ventral diverticulum of the phallus with distinct dorsal caudal and ventroapical protuberances. Previously, each group included five and 10 species, respectively; members of the dentatum group ranged in length from 38.0 to 52.0 mm, whereas those of the subspinosum group ranged from 26...

The male imagoes, larvae, and eggs of Ameletus allengaensis sp. nov. and Ameletus sirotskii sp. nov. from the Russian Far East are described. Based on the structure of the male genitalia, the imago and larvae of A. allengaensis sp. nov. and A. sirotskii sp. nov. are similar to those of A. camtschaticus, but the discovery of these new species and separation from A. camtschaticus were confirmed by studies of the morphology of the larvae and male imago, as well as molecular analysis. Identity of various developmental stages of the new species were confirmed by analysis of the mitochondrial gene cytochrome oxidase 1 (COI) DNA barcode, which was also used to reconstruct the phylogenetic relationships within the genus Ameletus...

The genus Zoica Simon, 1898 comprises the smallest members of the family Lycosidae (Lehtinen & Hippa 1979; Framenau et al. 2009) and all the members are vagrant (Lehtinen & Hippa 1979). The genus was revised by Lehtinen & Hippa (1979) and currently has 12 described species (World Spider Catalog 2017). The species Zoica puellula (Simon, 1898) was based on an unspecified number of female specimens from Sri Lanka, and its original description (Simon 1898) is inadequate and lacks illustrations. The male and female genitalia of this species were subsequently illustrated several times (Roewer 1960; Lehtinen & Hippa 1979; Tikader & Malhotra 1980); however these illustrations are insufficient for proper identification and the internal female genitalia of this species have not been illustrated...

Schaus (1929: 49) described Boalda gyona in a monobasic genus known only from the holotype taken in Santa Catarina, Brazil. Biezanko et al. (1957) reported the species from Uruguay. A number of specimens of Boalda similar to gyona were collected recently in Paraguay, at least two of which match the anomalous Argentinian taxon Nephelistis pulcherrima Köhler (1947: 77-78). Herein the genus Boalda is reviewed, with one new species described from the Paraguayan samples, and with N. pulcherrima transferred Boalda...

A new Afrotropical species of Anagrus Haliday (Hymenoptera: Mymaridae), A. nedotepae Triapitsyn sp. n., is described and illustrated. The type series was reared from parasitized eggs of the leafhopper Nedotepa curta Dmitriev (Hemiptera: Cicadellidae) during a survey for its natural enemies in Côte d'Ivoire. This peculiar leafhopper, recently described from Ghana (Dmitriev 2016), lays its eggs on leaflets of coconut palm, and could be an economically important pest of this crop in West Africa, particularly because it is a suspected vector of the phytoplasma associated with the Côte d'Ivoire Lethal Yellowing disease of coconut, as characterized by Arocha-Rosete et al...

The family Sisyridae (spongillaflies) is a small group of neuropterans distributed in all Biogeographic realms (Cover & Resh 2008). As in Nevrorthidae, Sisyridae is distinguished among other Neuroptera families by their strictly aquatic larvae (Wichard et al. 2002). The phylogenetic relationships of Sisyridae have been controversial i.e. the family was recovered at different positions within the Neuropterida phylogeny as a basal group among members of Neuroptera or whitin the suborder Hemerobiiformia with a very variable placement (Randolf et al...

Prokofiev (2015a) described two new genera and species of Amblyopinae and reported new amblyopine records from waters off Indonesia, the Philippines, and Vietnam. In reviewing Prokofiev's figures and reading the descriptions of his new genera, Biendongella Prokofiev, 2015 and Sovvityazius Prokofiev, 2015, it appeared likely that these new taxa were based on species also under examination by Koichi Shibukawa and me. However, some differences existed between our specimens and those described by Prokofiev in the pterygiophore formula (DF), the presence/absence of hypural 5, and the number of epurals...

A new genus and a new species of Neotropical cricket is described: Pepoapua cariacica n. gen., n. sp., occurring in four Atlantic Forest remnants in the states of Bahia and Espírito Santo, Brazil. This new genus is morphologically similar in external characteristics, both male and female genitalia, with two other Neotropical genera of Nemobiinae: Amanayara and Kevanemobius. The combination of the external morphological characteristics, along with male genitalia, characterize a new genus through combination of the following characters: (i) males and females with morphologically similar tegmina; (ii) tegmina reduced, not reaching half of the second abdominal segment; (iii) dorsal field of the tegmina with parallel veins, without stridulatory vein or any specialized area for sound production; (iv) tibia of the first pair of legs without tympanum; (v) tibia of the third pair of legs with seven dorsal spurs, four inner and three outer, the proximo-dorsal inner spur reduced in size and the disto-dorsal inner spur without glandular aspect; (vi) ovipositor with distal portion of the dorsal and ventral valves serrated; (vii) male genitalia without evident bristles or sensillas; (viii) pseudepiphallic median lobe presenting apical and ventral projections...
