Rancho Nuevo, San Cristobal de las Casas, 16°40’14.9’’N – 092°35’03.7’’W , m 2100, Chiapas , Mexico . Type repository. Dellacasa Collection, Genoa, Italy . Description. Length 5.0-5.5 mm; shortly oblong, strongly convex, shiny, glabrous. Blackish, clypeal margin and elytral suture shadowy reddish; legs dark brown; antennal club piceous. Head with epistome feebly convex medially, somewhat depressed anteriorly, rather finely, evenly not closely punctured, punctation denser and coarser distally, sparser and finer medially; clypeus feebly sinuate at middle, round at sides, rather thickly bordered, edge slightly reflexed, glabrous; genae obtusely round, not ciliate, feebly protruding from the eyes; frontal suture almost obsolete, not tuberculate; front rather finely evenly punctured. Pronotum moderately transverse, convex, dually punctured; larger, moderately coarse punctures, five to six times larger than small ones, irregularly and rather sparsely scattered on sides, broadly lacking on disc; small, extremely fine punctures evenly scattered throughout, nearly imperceptible on disc; lateral margin almost straight, finely bordered, edge glabrous; hind angles broadly truncate, truncation not inwardly sinuate; base feebly bisinuate. Scutellum elongate, somewhat depressed laterally, very finely, sparsely punctured toward base. Elytra amygdaliform, strongly convex, moderately denticulate at shoulder, rather finely striate; striae superficially, not closely punctured, feebly crenulate; interstriae flat on disc, moderately convex on preapical declivity, almost imperceptibly punctured.
