Diagnosis. Clypeus trapezoidal with anterior margin truncate; eyes small; pronotal anterior and posterior angles acute and projected; scutellum punctate; six longitudinal costae; metacoxae with dense tuft of bristles; protibia slightly sculptured; metatibial spurs equal in length; in males parameres narrow, smooth, not deflected distally; flatted laterally; phallobase not constriction.

Description. Holotype. Male. Length 12.1 mm; width 5.0 mm (variation 10.5–12.1 mm; 4.6–4.8 mm). Head: Shiny, reddish brown; distance between eyes three times the width of one eye; frons as long as the clypeus; clypeus trapezoidal with anterior margin truncate; labrum, in frontal view, less than one third the width of the clypeus; mandibles with mola with carinae slightly impressed; distal maxillary palpomere width twice the width to apex; galea with seven teeth visible in frontal view; labium with apex wider than the base; labial anterior margin strongly sinuate. Prothorax: Pronotal anterior and posterior angles acute and projected. Pterothorax: Scutellum with fine and dense punctures; mesosternum with long tuft of bristles; metasternum with long and dense tuft of bristles on disc. Elytra: Six longitudinal costae; elytral suture strongly elevated, unicolored and with fine punctures fading towards the proximal region. Legs: Protibia slightly sculptured; protarsomere I longer than protarsomere II; mesotarsomeres with proximal portion punctate; metacoxae with dense bristles; metatibial spurs with equal lengths. Abdomen: Ventrites with conspicuous punctures; ventrite II longer than III; ventrite IV shorter than ventrite V; propygidium with both coarse and fine punctures and short bristles laterally; pygidium wider than it is long, dense and fine punctures on margins and disc smooth; basal region flat laterally; base of pygidium wider than posterior margin of the propygidium. Male genitalia: Parameres narrow and smooth; not deflected distally; outer margin curved; inner margin slightly curved, almost straight on distal portion; flatted laterally; phallobase in dorsal view, distal margin not constricted.

Sexual dimorphism. Female with length of antennal club shorter than males. Length 11.0 mm and width 4.1 mm (12.0 mm; 5.0 mm).

Etymology. From the Latin striâtus “furrowed, grooved, fluted, striated”. The name is referring to the ridges of the elytra and is an adjective in the nominative singular.

Type locality. BRAZIL, Extrema. Estrada da Torre da Embratel , 160 m.

Geographical Distribution. Brazil (Minas Gerais, Rio de Janeiro, São Paulo, and Paraná) .
