Neurostigma Enderlein, 1900 (Psocodea, ‘Psocoptera’, Epipsocidae): a new species of Brazilian Atlantic Rainforest, and new records for Brazil

Abstract

A new species of Neurostigma, collected in an area of Atlantic Rainforest, in the Brazilian state of Minas Gerais, is described and illustrated, namely: Neurostigma atlanticum sp. nov. The first record of Neurostigma garcialdretei Mendivil-Nieto, Gonzalez-Obando & Carrejo-Gironza, 2020, from Brazil was made.

Neurostigma Enderlein, 1990: new records, update diagnosis, description, redescription, description increment of females, and a new synonymy (Psocodea: “Psocoptera”: Epipsocidae)

“…Comments: Reategui et al (2022b) recorded nine eggs present in the described female, but here, 14 eggs were found in the analyzed female. Perhaps not all eggs were developed in the female described by Reategui et al (2022b), or there is a wide variation in the number of eggs in this species.…”

“…Phallosomal arch narrow and widening at the ends, anteriorly with a U-shaped area, then with a small transverse part, almost straight, posteriorly elongated vertically, ending in an almost elliptical area, with convex inner margin and blunt outer margin (See fig. 2J in Reategui et al, 2022b). Endophallus heartshaped, radular sclerites with small denticles, more pro- Male: As described by New (1980).…”

“…But after 40 years, this species was mistakenly described as a new species by Mendivil Nieto et al (2020) (Neurostigma garcialdretei Mendivil Nieto, Gonzalez Obando & Carrejo Gironza) from three localities in southeastern Colombia (Vaupés-Mosiro-Itajura, Amazonas-Leticia, Amazonas-Amacayacu). It was also recorded for Amapá by Reategui et al (2022b) as N. garcialdretei. The latter authors, a few months after the publication of the new record, examined new material from Reserva Biológica de Cueiras-ZF2, Amazonas, Brazil, and found female specimens of N. roesleri, along with male specimens identical to N. garcialadretei.…”

“…A small dark brown spot at the base of the Pterostigma and this one with its transverse veins pigmented along its entire length (See figs. 2B-C, 7-9 in Reategui et al, 2022b). Hindwings with their proximal part half yellowish to brown, with two hyaline areas almost elliptic (See figs.…”

“…Brazil is the richest country for Neurostigma species with seven species, most belonging to species group II, distributed in 10 Brazilian states (Table 1) (Silva-Neto & Garcia Aldrete, 2020;Reategui et al, 2022b). However, the description of females is only documented for three species: Neurostigma dispositum Roesler, 1940;Neurostigma roesleri New, 1980 andNeurostigma xanthopterum New, 1980 (Table 1) (Reategui et al, 2022a).…”
