Two new species of Lepidocyrtus (Fractocyrtus) Cipola & Bellini (Collembola, Entomobryidae, Lepidocyrtinae), with new records and a new name for Lepidocyrtus (F.) americanus Cipola & Bellini, 2018

Abstract

Herein we propose a new name, Lepidocyrtus (Fractocyrtus) amazonaensis nom. nov. Cipola, to replace L. americanus Cipola & Bellini 2018, a combination preoccupied by Marlatt (1896). In addition to new geographic records for the species, two new species of Fractocyrtus are described: L. (Fractocyrtus) andensis sp. nov. from the Colombian Andes and L. (Fractocyrtus) chicomendesi sp. nov. from the Occidental Brazilian Amazon. The new species differs from other members of the subgenus in body color, dorsal chaetotaxy of the head, chaetotaxy of the third and fourth abdominal segment, postlabial chaetotaxy, trochanteral organ, collophore and furcula, beyond morphology on the lateral process of the labial papilla E. New patterns of body pseudopores are described and added to the new diagnosis for the subgenus. Fractocyrtus now has four species, with distribution from the Andes to the Oriental Brazilian Amazon.

New records of Odonata (Insecta) for the extreme northwest of the Brazilian Amazon

“…A recent survey conducted in Amazonas state revealed that municipalities with large territories, such as São Gabriel da Cachoeira (SGC), remain under-sampled taxonomically, making these areas a priority for Odonata research (Koroiva et al, 2020). SGC, also known as "Cabeça do Cachorro" ("Dog's Head"), located in the extreme northwest of Brazil, stands out by its high biodiversity, as is observed in various groups of animals (Cipola & Viana, 2023;Hamada et al, 2006;Lourenço, 2005;Nogueira et al, 2014). Therefore, it is reasonable to presume that numerous species are yet to be discovered, and that some have not yet been adequately documented from the state of Amazonas or Brazil in general.…”
