Type species.

Pseudochlamys megalostomoides Lacordaire 1848, by monotypy.

Diagnosis.

Pseudochlamys can be distinguished from all other genera in the tribe by: head not completely retracted into prothorax; mandibles enlarged in males (sexual dimorphism); intercoxal prosternal process strongly and abruptly constricted beyond anterior margin; and prosternal process more than ¾ as long as intercoxal prosternal process. These beetles are small sized (length 3.45-4.72 mm), cylindrical; body usually yellowish; canthus of eye as yellow as rest of frons; pronotum and elytra glabrous; head not completely retracted into prothorax; mandibles enlarged in males; antenna serrate beyond antennomere III, antennomere II slightly widened, globose, antennomere V as large as VI; posterior pronotal lobe with well differentiated notch; intercoxal prosternal process strongly and abruptly constricted beyond anterior margin; sutural serration of elytra complete; elytral tubercles poorly developed; tarsal claws bifid or appendiculate.

Distribution.

This genus contains only five species, distributed in North, Central, and South America ( Chamorro-Lacayo and Konstantinov 2009; Karren 1972).
