Taxonomic update on Cordyligasterini (Diptera: Tachinidae: Dexiinae), new generic synonyms and new species of Neosophia Guimarães

Abstract The New World tribe Cordyligasterini (Diptera: Tachinidae) is known to present a remarkable morphology, being brightly colored and many species with wasp‐like mimicry. The tribe has currently eight genera and 27 species, with four of these genera being monotypic. Here we describe two new species of Neosophia Guimarães, N . argentifasciata sp. n . from the Dominican Republic and N . pakitza sp. n . from Peru. We also synonymize two other genera with Neosophia , the monotypic Sophiella Guimarães, syn. n . and the poorly studied Leptidosophia Townsend, syn. n . which has two species, resulting in the new combinations: Neosophia flava (Aldrich, 1929), comb. n ., Neosophia lanei (Guimarães, 1982), comb. n . and Neosophia lutescens (Townsend, 1931), comb. n . An updated key for the genus is provided, as well as amendments to the Cordyligasterini generic key.
