ABSTRACT Heptozus Lindner, with a known distribution in Costa Rica, Ecuador and Panama, is recorded for the first time in Brazil with the occurrence of Heptozus hansoni James in the state of Mato Grosso do Sul.

Insect (Hexapoda) diversity in the oceanic archipelago of Fernando de Noronha, Brazil: updated taxonomic checklist and new records

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.

Descrição da larva, exúvia pupal e macho de Leucotabanus albovarius (Walker) (Diptera, Tabanidae) da Amazônia Central / Description of larva, pupal exuvia and male of Leucotabanus albovarius (Walker) (Diptera, Tabanidae) from Central Amazonia

Immature stages and male adult of Leucotabanus albovarius (Walker, 1854) are described and figured for the first time. The larva was found in rotten wood of the palm Bactris gasipaes Kunth (Arecaceae) near Manaus. Differential diagnoses of the known immatures of Leucotabanus Lutz are presented.

Estágios imaturos e macho adulto de Leucotabanus albovarius (Walker, 1854) são descritos e ilustrados pela primeira vez. A larva foi encontrada em tronco de pupunheira em decomposição, Bactris gasipaes Kunth (Arecaceae), nas proximidades de Manaus. Diagnoses diferenciais dos imaturos de Leucotabanus Lutz são apresentadas.
