Identification

Although some spp. are distinctive (e.g., T. collaris, T. obtusus), many are difficult to identify, esp. from photographs. To maximize the likelihood of a species-level identification, include (1) a clear dorsal shot showing the body outline and especially that of the pronotum; (2) a detail shot of the pronotum clearly showing the anterior and basal angles and the basal marginal bead; and (3) a detail shot of the antennal club showing the sensory areas. --M.C. Thomas's comment

Range

cosmopolitan (all but a handful in the New World, mostly Neotropical), incl. most of NA(3)(2)(1)

Habitat

most spp. under bark; T. mauritanicus in stored grain
