A new genus of lyrate curtain-web spiders (Araneae: Mygalomorphae: Dipluridae) from southeastern Brazil, with two new species and revalidation of a formerly described species
Abstract
A new Brazilian genus of curtain-web spiders, family Dipluridae
Simon, 1889, Harpathele gen. nov., is described, with
Harpathele gymnognatha comb. nov. (Bertkau, 1880) (Rio de
Janeiro state) as its type species. The new genus is a lyrate
Diplurinae and it is known only from southeast Brazil. It may be
recognized by the relatively small body, maxilla with dorsal
transverse suture showing distinct curve at its basal third, a field
of numerous long and thin setae above that suture, and a field of
small rigid bristles below it, among other characters. Harpathele
gymnognatha comb. nov. (Bertkau, 1880) is revalidated and
redescribed, with the designation of a neotype and the first
description of a male, based on specimens collected in its type
locality that match the original description and illustrations, and
is pointed as senior synonym of Diplura annectens (Bertkau,
1880). Additionally, two species of the new genus are described:
Harpathele cariacica sp. nov., based on females from Espírito
Santo state, and Harpathele salinas sp. nov., based on males
from Rio de Janeiro state.
