Pico de Orizaba, Veracruz , Mexico . Type repository. Dellacasa Collection. Genoa, Italy . Description. Length 3.5–4.0 mm; oval-elongate, moderately convex, subopaque; head and pronotum glabrous, elytra laterally and subapically shortly pubescent. Blackish. Head with epistome dull, feebly gibbous on disc, subrugosely confusedly punctured, punctation more superficial on disc; clypeus distinctly sinuate at middle, subangulate at sides, thinly bordered, edge glabrous, faintly upturned; genae obtusely round, shortly sparsely ciliate, distinctly protruding from the eyes; frontal suture not tuberculate, feebly raised medially and laterally; front coarsely, not densely punctured. Pronotum transverse, moderately convex, somewhat irregularly coarsely punctured, punctures distinctly umbilicate, denser and almost confluent on sides, more superficial on disc, herein with impunctate longitudinal narrow areola; lateral margins almost parallel, thickly bordered, edge glabrous; hind angles obtusely round; base feebly bisinuate, distinctly entirely bordered. Scutellum superficially alutaceous, sparsely coarsely punctured on basal half. Elytra moderately convex, oval, somewhat widened posteriorly, not denticulate at shoulder, laterally and on preapical declivity with short recumbent setae; epipleural carina very distinct, striae shiny, moderately deep, coarsely not closely punctured, feebly crenulate; interstices flat, rather dull, with coarse, confluent, vermiculous punctation. Hind tibiae upper spur somewhat shorter than first tarsal segment; latter as long as following three segments combined. Male: fore tibiae spur stout, subcylindrical, acuminate and distinctly inwardly curved apically; head and pronotum relatively less convex, wider and less coarsely punctured; aedeagus Fig. 4–5 . Female: fore tibiae spur almost straight; head and pronotum more convex, somewhat narrowed anteriorly, more coarsely punctured. Type material.
