Length 20-25 mm. C. glabratum, as happen with C. peregrinator and C. sponsa, is characterized by the presence of setae on the metatrochanters. Moreover, it is easy to differentiate because it is a relatively small species with smooth and shiny elytra, with slight striae, and with rather transverse pronotum.
C. glabratum lives in Panama and Colombia. It is also supposed living in Bolivia, but besides the description of the type of Calosoma bolivianum, no other findings are known from there. To these countries Jeannel (1940: 204) added Peru, followed by subsequent authors (Erwin et al., 2015: 154), but without further specification. Finally, some remains of C. glabratum have been found in a deposit of oil bearing sand in Trinidad, at Fyzabad (Blair, 1927: 137) but no recent findings have been reported from the island or from the Venezuelan mainland.
