Genal carinae not bent outwards and obsolete ventrally, reaching hypostomal carinae far from mandibular bases in acute angle of 70°. Hypostomal carinae ± elevated.

Mesopleural discs granulate or finely rugose, with ± distinct punctures; specula granulate, matte; dorsal impressions with moderately dense striae. Prepectal carina not elevated and absent on the transversal parts. Metapleura finely rugose; coxal carinae partly developed. Scutellum wider than long, with lateral carinae in basal 0.3.
