Abstract

Tagalis matamorosae n. species and Tagalis pagu n. species are described from specimens collected in Barro Colorado (Panama) and Rio Grande do Sul (Brazil), respectively. Among the species of Tagalis, both new species have coloration patterns and genital structure particularly different. Tagalis matamorosae n. species is the unique species with a gonoplac composed by a pair of sclerites, and T. pagu n. species shows the posteromedial process of pygophore with a curvature exclusive within the genus. Digital images of external morphological characters and of the genitalia are provided. To facilitate the identification of the new species, an updated key to the species of Tagalis is presented. Male genital structures along the genus and its taxonomic and phylogenetic implications are discussed.
