Abstract 

A new species, Curius chemsaki (Coleoptera: Cerambycidae: Cerambycinae: Curiini), from 
Venezuela is described. Features distinguishing the new species from its congeners as well as a key 
to the four species are presented. Sexual dimorphism in pronotal and prosternal morphology within 
the genus is also discussed.

Introduction 

As currently defined, the genus Curius Newman, 1840 contains three species: Curius 
dentatus Newman, 1840, known from southeastern United States, Curius panamensis 
Bates, 1885, known only from Panama, and Curius punctatus (Fisher, 1932), an endemic 
Cuban species (Monne, 2005; Monne & Hovore, 2005; Nearns et al., 2005; Peck, 2005). 
LeConte (1873) designated the tribe Curiini (= Curii) with Curius as the type genus and 
synonymized Plectromerus concinnatus Haldeman, 1847 with C. dentatus. Linsley (1963)
