Aratea Lacordaire, 1848 Fig. 4
Lacordaire 1848: 467; Chapuis 1874: 151; Jacoby and Clavareau 1906: 73; Guérin 1943: 86; Monrós 1953a: 261; Moldenke 1981: 88.
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.
