Criodion angustatum Buquet, 1852 and C. pilosum Lucas, 1857 (Coleoptera: Cerambycidae: Cerambycinae) are synonymized with C. tomentosum Audinet-Serville, 1834. The holotypes of C. angustatum and C. hirsutum, and syntypes of C. pilosum and of C. tuberculatum Gahan, 1892 are illustrated for the first time. One of the type localities of C. tuberculatum is corrected.

Currently, Criodion Audinet-Serville, 1834 includes 13 species distributed from Guatemala to southern South America (Monné 2021; Tavakilian and Chevillotte 2021). Despite the relatively small number of species, they encompass several problems with their identification. For example, the specimens often identified as C. murinum Nonfried, 1895 from Costa Rica (e.g. Maes et al. 2010), does not differ from specimens of C. cinereum (Olivier, 1795). This suggests that the specimens have been misidentified or that C. murinum is a junior synonym of C. cinereum. As at least most species of the genus are intraspecifically highly variable morphologically, this is likely the reason for misidentifications.

Herein we solve part of the problems in the species of the genus, synonymizing two species with C. tomen­tosum Audinet-Serville, 1834. Furthermore, we are correcting a mistake regarding one of the type localities of C. tuberculatum Gahan, 1892.
