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.
