RESUMO

In recent years, our knowledge of the Oriental fauna of Neriidae has improved with the studies of Telostylus Bigot, 1859 and Teloneria Aczél, 1954. However, the small genera (less than three species) have never been revised and their taxonomy remains obscure. Neriidae has 18 genera of which 10 occur exclusively in the Oriental and Australasian Regions, including four monotypic genera, of which one, Protonerius de Meijere, 1924, is only known from the female holotype of Protonerius guttipennis de Meijere, 1921 from Indonesia. We here describe a second species of the genus, Protonerius opacus sp. nov., based on a female specimen from Selangor, Malaysia, which differs from the type species of the genus by the patterns of infuscate spots on the wing and the coloring of pleuron and femora. Additionally, an identification key for the two species and an updated diagnosis of the genus are provided.(AU)

RESUMO

Although a recent revision of the genus Glyphidops Enderlein covered most its known, some of the Brazilian forms were not surveyed. Here we take advantage of the excellent morphological work available in the literature and redescribe Glyphidops (Glyphidops) filosus, based on 91 specimens (43 males and 48 females) from the States of Amazonas and Goiás, including Brasília, Brazil. We also provide a study of male genitalia using scanning electron microscopy (SEM) and female genitalia and spermathecae, using light microscopy (LM). We present descriptions of the following structures in male genitalia: epandrium, hypandrium, surstyli, cerci and sections of aedeagus, and in female genitalia: oviscape, bursa copulatrix, ‘S bend and spermatheca. An update list of Brazilian species of Glyphidops Enderlein is also presented.(AU)

RESUMO

Of the 116 Neriidae species known to date, 113 species have not been studied in their immature stages. Here, we examine the development of the immature stages of Glyphidops (Oncopsia) flavifrons (Bigot, 1886), which has one of the broadest distributions of Neriidae in southern North America, Central America, and South America; offering excellent opportunities for biological studies. A population of this species was monitored over a five month period. The following characteristics were tracked for a population located on the University of Valle campus in Cali, Colombia: oviposition duration, number of eggs per egg mass and lifespan of each immature stage (egg, larva, and puparium) under natural conditions (in situ). The external morphology of the egg, larva, and puparium were described; their stages lasted 58 (± 4) hours, 10 (± 1) days and 13 (± 1) days, respectively. The lapse of time for each larval instar was statistically supported by using Tukey comparisons and cluster analysis of hypopharyngeal sclerite length and mandibular area. In addition, it was also sustained throughout the morphological study of structural changes in mouth hook, and anterior and posterior spiracles. Finally, the presence of the labial and epipharyngeal sclerites are reported as new characters of Nerioidea. Natural history data are provided.
