Abstract

ABSTRACT The South American genus Heteropyge Silvestri, 1897 is revised, accommodating now six accepted species. Adults of the poorly known species Heteropyge araguayensis (Schubart, 1947) are described for the first time from near-topotypic material collected near the Araguaia River, state of Mato Grosso, Brazil. In addition, based on recent samplings and on material from Schubart’s collection, H. bidens (Schubart, 1945) is removed from the synonymy of H. cayennophilus (Silvestri, 1897) and revalidated. Both species show significant differences concerning the gonopods and male leg-pair 1. New records and additional data for H. bidens and H. cayennophilus are provided, as well as an updated checklist of the species belonging to Heteropyge.

Highlights

The South American genus Heteropyge Silvestri, 1897 is revised, accommodating six accepted species
Silvestri (1897a) described the genus Heteropyge to accommodate Odontopyge paraguayensis Silvestri, 1895, which was originally assigned to Odontopygidae because of the presence of spiniform dorsal process on each paraproct
Most individuals of H. araguayensis were sampled under cattle dung in a floodplain area

Summary

Introduction

The South American genus Heteropyge Silvestri, 1897 is revised, accommodating six accepted species. Adults of the poorly known species Heteropyge araguayensis (Schubart, 1947) are described for the first time from near-topotypic material collected near the Araguaia River, state of Mato Grosso, Brazil. Based on recent samplings and on material from Schubart’s collection, H. bidens (Schubart, 1945) is removed from the synonymy of H. cayennophilus (Silvestri, 1897) and revalidated. Both species show significant differences concerning the gonopods and male leg-pair 1. We revalidate H. bidens, based on types and additional examined material, and provide new records and additional data for H. cayennophilus
