Intraspecific wing venation and phallosome taxonomy updates in species of Loneura Navás (Psocodea, Ptiloneuridae), with one new species from cave and key to Loneura species from Brazil

Abstract

Cavernicola sp. nov. is here described and illustrated, based on male and female specimens collected in caves located in an ecotone region between the Brazilian Savannah (Cerrado biome) and the Atlantic Forest, in Minas Gerais state, southeastern Brazil. Illustrations are provided of 19 types of variation in the fore and hindwings veins of males and females. Illustrations are presented of the holotype of L. maracaensis García Aldrete, along with illustrations of 18 types of variation in the fore and hindwing veins of males and females. Additionally, a new methodology applied in some specimens of L. maracaensis to process the genital pieces allowed us to know the arrangement and delimitations of each of the sclerites and their possible position during copulation. We therefore propose a phallosome taxonomic update. In these everted male genitalia, the spermatic sac and attached glands were identified for the first time. An identification key is presented to the Brazilian species of Loneura, based on males.
