Type species.

Aratea costata Lacordaire, 1848. By monotypy.

Diagnosis.

This genus is easily recognized by the presence of strong parallel carinae on the elytra; other diagnostic characters include: frons very narrow; scutellum slanting posterodorsally, distinctly protruding from the plane of elytra; intercoxal prosternal process nearly absent between fore coxae; epipleural margin broadly angled, tip rounded; elytra without pubescence; frons with medial pit, densely and coarsely punctate throughout; and pygidium strongly convex.

Distribution.

Only two species from Brazil, one present in Argentina, likely to also occur in Paraguay.

Remarks.

Agrain and Roig-Juñent (2011), found eight autapomorphies for the genus, among them elytra with strongly marked longitudinal striae constitutes an exclusive synapomorphy to the genus.
