ABSTRACT
Pseudoscelolabes Collin, 1933, an endemic New Zealand genus, is revised, including the description of a new species, P. lesagei Sinclair Barros sp. nov. The male and female terminalia of the genus are described and illustrated for the first time. An identification key to the two included species and a map with distribution records are provided. The relationships of the genus within Ocydromiinae are discussed.

This study presents some updates on the Brazilian hangingflies species of the genera Issikiella Byers, Nannobittacus Esben-Petersen, and Pazius Navás (Insecta: Mecoptera: Bittacidae). All species with records from Brazil were included in the study, resulting in some new state records and a new synonym (Pazius cinctipes Byers and Florez under P. ornaticaudus Penny). Biological notes on P. ornaticaudus and distribution maps for all species were also provided.

Haemagogus (Haemagogus) janthinomys (Dyar, 1921), the major neotropical vector of sylvatic yellow fever virus, is notoriously difficult to maintain in captivity. It has never been reared beyond an F1 generation, and almost no experimental transmission studies have been performed with this species since the 1940s. Herein we describe installment hatching, artificial blood feeding, and forced-mating techniques that enabled us to produce small numbers of F3 generation Hg. janthinomys eggs for the first time. A total of 62.8% (1562/2486) F1 generation eggs hatched during ≤10 four-day cycles of immersion in a bamboo leaf infusion followed by partial drying. Hatching decreased to 20.1% (190/944) in the F2 generation for eggs laid by mosquitoes copulated by forced mating. More than 85% (79/92) female F2 mosquitoes fed on an artificial blood feeding system. While we were unable to maintain a laboratory colony of Hg. janthinomys past the F3 generation, our methods provide a foundation for experimental transmission studies with this species in a laboratory setting, a critical capacity in a region with hyper-endemic transmission of dengue, Zika, and chikungunya viruses, all posing a risk of spillback into a sylvatic cycle.

ABSTRACT Three new species of Pseudosympycnus Robinson are described and illustrated from Peru: P. pennipes sp. nov., P. latitarsus sp. nov. and P. rafaeli sp. nov. In addition, Pseudosympycnus latipes (Parent) is recorded for the first time from the country and the male terminalia are illustrated. The first photographs of the holotype of P. bicolor Robinson and an updated key to species of the genus are provided.
ABSTRACT
Two individuals of the jaguar, Panthera onca (L.), were captured near the municipality of Presidente Figueiredo, Brazilian Amazon, during the years of 2017 and 2018. The jaguars presented furuncular myiasis caused by the human botfly Dermatobia hominis (L.) on the rear thighs and tail. This is the first record of infestation of D. hominis in P. onca in the Amazon region.

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.
ABSTRACT
Three new species of Chvalaea Papp Földvári are described and illustrated: Chvalaea annularis sp. nov., C. ecuadoriensis sp. nov., and Chvalaea sinclairi sp. nov. In addition, an illustrated key, distribution map, new records, and updated diagnoses of all Neotropical species are presented.
