Aulacochlamys Monrós, 1951c: 657; Chamorro-Lacayo and Konstantinov 2009: 66.

Type species.

Exema costicollis Lacordaire, 1848, by original designation.

Diagnosis.

The most salient feature of this genus is the presence medially on the pronotum of six elevated distinct, small, sharp, longitudinal carinae, which converge medially near the posterior margin, reminiscent of a fan. These are small beetles (less than 3 mm length), cylindrical; with antennae serrated beyond antennomere V. antennomeres III-V slightly widened, but not dilated distally; pronotal base opposite mesoscutellum (posterior pronotal lobe) with or without notch; intercoxal prosternal process gradually narrowing posteriorly, broadening before apex; metascutellum concealed by elytra; elytral suture completely serrate, although serration may be weak near scutellum, elytral tubercles well developed. Tibiae slightly curved, cylindrical. Aulacochlamys can easily be distinguished from Chlamisus Rafinesque by the presence of the six longitudinal carinae on its pronotum.

Distribution.

Pantropical, except Australia ( Monrós 1951c). Six of the 21 Neotropical species are present in Argentina.
