This genus is characterized by the moderately transverse pronotum, which lateral margins arcuate towards anterior angles which are strongly round, posterior angles obtusely rounded; the broadly and entirely explanate lateral margins of elytra; the narrow prosternal process, very slender palpi and distinctly appendiculate claws.

Pronotum: Much wider than long, strongly declivous anteriorly; anterior collar distinctly developed, delimited posteriorly by a deep transverse furrow, lateral portions thickened; lateral margin narrowly explanate, not projecting anteriad and ventrad, but distinctly elevated dorsad around its middle, distinctly emarginated anteriad of humeri in dorsal view; humeral angle rounded, obtuse, distinct; posterolateral angle very broadly rounded, obsolete (Figs.

DIAGNOSIS: This species is only known from females and is recognized by the following combination of characters: uniformly dark reddish brown, apices of forewings narrowly whitish, abdominal connexiva reddish; clypeus shortened, not extending below bucculae; frons explanate and raised posteriorly, crestlike in female (Fig.
