| Abstract A new species of Xenurobrycon isdescribed from tributaries of the rio Tapajós, Pará, Brazil. It is diagnosed from all congeners by the dark color of the posterior half of both caudal-fin lobes, the presence of infraorbitals one, two, and three, the presence of a set of lamellar processes on eighth principal caudal-fin ray of mature males, the presence of bony hooks similar in size or decreasing posteriorly on last unbranched and first 9-12 branched anal-fin rays of mature males, the presence of only conical teeth on both jaws, the lack of the adipose fin and the presence of 15-18 predorsal scales. The description of the new species increases the number of species in Xenurobrycon to six. An updated key to the species of the genus is provided. |

| Eupanthalis rudipalpa Amaral & Nonato, 1984 was described based on three incomplete, colorless specimens and has not been reported since its original description; the epithet rudipalpa means "hirsute palps", a characteristic that separates it from other congeneric species. Eupanthalis McIntosh, 1876 and Euarche Ehlers, 1887, and their respective type species, E. kinbergi McIntosh, 1876 and E. tubifex Ehlers, 1887, were considered synonyms (E. rudipalpa as a junior synonym of E. tubifex, a cosmopolitan species) by some authors, because both have sessile eyes and two or three antennae. Nonetheless, these two genera are, in fact, distinct. Their type species can clearly be separated using some prostomial features. We provide an emended diagnosis of... |

| The genus Polistes is revised for the West Palaearctic region based on morphology and DNA barcodes. The revision includes all known West Palaearctic species, raising the number of species in Europe to 14 and to 17 for the West Palaearctic realm. DNA barcodes were recovered from 15 species, 14 of which belong to the subgenus Polistes, and one, P. wattii, to the subgenus Gyrostoma. An integrative taxonomic approach combining morphology and molecular data (DNA barcoding) was employed to resolve longstanding taxonomic problems in this group. Two species, P. austroccidentalis van Achterberg & Neumeyer, sp. n. (= P. semenowi auctt.) from W and SW Europe and P. maroccanus Schmid-Egger, sp. n. from Morocco are described as new. Polistes bucharensis Erichson,... |

| ABSTRACTHere we describe seven new species of Limnophora from Ecuador: Limnophora bifasciatasp. nov. from Napo, Quito; Limnophora equatoriensissp. nov. from Zamora-Chinchipe, Zamora; Limnophora femurosetalissp. nov. from Zamora-Chinchipe, Zamora; Limnophora lamasisp. nov. from Zamora-Chinchipe, Zamora; Limnophora longivittatasp. nov. from Napo, Quito; Limnophora penaisp. nov. from Azuay, Cuenca and Limnophora polletisp. nov. from Napo, Quito. We provide an identification key for the ten recognized species of Limnophora from Ecuador, including L. marginata Stein, 1904, L. pica(Macquart, 1851) and L. saeva (Wiedemann, 1830). We also redescribed Limnophora marginata Stein, 1904, and designated designed lectotype male and paralectotypes males and females of... |

| Three new species of Peristicta Hagen in Selys from Brazil are described and illustrated: P. janiceae from Minas Gerais State (Diamantina, Gouvêa, Lagoa Santa, Serra do Caraça, Serra do Cipó, Urobotanga), P. jalmosi from Goiás State (Chapada dos Veadeiros, Reserva da Universidade de Brasília) and Minas Gerais State (Urobotanga, Lagoa Santa, Ponte Nova, São João del Rey,) and P. muzoni from Mato Grosso State (Serra da Bodoquena). An identification key for males of Peristicta is presented. |
