RESUMO
Abstract: The sweat bees from Fernando de Noronha Archipelago are presented and illustrated herein. The species recorded are Augochlora (Augochlora) laevipyga (Kirby, 1890), Augochlora (Augochlora) sp., new record, and Lasioglossum (Dialictus) atripyga (Kirby, 1890). The Kirby species are redescribed based on recently collected specimens, including the first illustration of the male terminalia. The unidentified species is also shortly characterized.

As espécies registradas são Augochlora (Augochlora) laevipyga (Kirby, 1890), Augochlora (Augochlora) sp., novo registro, e Lasioglossum (Dialictus) atripyga (Kirby, 1890). As espécies descritas por Kirby são redescritas com base em espécimes recentemente coletados, incluindo a primeira ilustração das terminálias dos machos. A espécie não identificada também é resumidamente caracterizada.
RESUMO
ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.
RESUMO
ABSTRACT The genus Neogriphoneura Malloch, 1924 is currently composed of 11 species with New World distribution. Neogriphoneura timida Curran, 1942 is recorded for the first time in South America, with occurrences in Brazil, Colombia and Trinidad and Tobago; and new Central American records are presented: Belize, Honduras and Mexico. Here we redescribe the species and present, for the first time, illustrations of the male terminalia and female spermathecae, and discuss the main diagnostic characteristics of external morphology. A brief discussion about the postcopulatory sexual selection in this species is proposed based on morphology of the spermathecae.
