Abstract

Hemipeplus quadricollis Pollock, 1999 (Coleoptera: Mycteridae: Hemipeplinae), was originally described from Rondonia State, Brazil, as its type locality, with 10 paratypes: eight from Brazil (Rondonia State) and two from Peru (Madre de Dios and Loreto departments). However, one of the paratypes from Peru (Madre de Dios) was later identified as a cryptic species, Hemipeplus pseudoquadricollis KC and Pollock, 2025. This raises questions about the single remaining paratype from Peru—whether the species truly occurs in Peru—and how many of the paratypes of H. quadricollis are actually H. quadricollis. In this study, all seven remaining paratypes of H. quadricollis that were not studied by KC and Pollock (2025) were examined based on morphological characters to address these two questions. It was determined that the remaining paratype of H. quadricollis from Peru, collected in Loreto Department, is H. quadricollis, thus confirming its presence in Peru, while three out of the 10 paratypes of H. quadricollis are H. pseudoquadricollis.
