( Fig. 114-119 )

Type locality. Xuatusco env., Parada der los Pinos, Veracruz, Mexico.

Type repository. Dellacasa Collection, Genoa, Italy.

Description. Length 3.5-4.5 mm; shortly oblong, strongly convex, shiny, glabrous. Chestnut brown; pronotum usually darker, elytra shadowy paler basally and apically; legs chestnut brown; antennal club piceous. Head with epistome feebly convex, slightly depressed antero-medially, coarsely, densely, somewhat irregularly punctured throughout; clypeus moderately sinuate at middle, round at sides, finely bordered, edge faintly reflexed, very shortly, sparsely bristled; genae obtusely round, nearly imperceptibly bristled, almost not protruding from the eyes; frontal suture finely impressed, not tuberculate; front coarsely, densely, evenly punctured. Pronotum moderately transverse, convex, dually punctured; large coarse punctures, four to five times larger than small ones, much denser on sides, sparser and fewer on disc; small, very fine punctures evenly sparse throughout; lateral margins nearly straight, rather finely bordered, edge glabrous; hind angles distinctly truncate, truncation very feebly sinuate inwardly; base feebly bisinuate. Scutellum narrowly elongate, somewhat depressed laterally, sparsely finely punctured on basal half. Elytra broadened posteriorly, convex, denticulate at shoulder, deeply striate; striae coarsely, not closely punctured, crenulate; interstriae moderately convex on disc, subcariniform on preapical declivity, near imperceptibly punctured. Hind tibiae upper spur shorter than first tarsal segment; first tarsal segment longer than following three segments combined. Male: pronotum relatively a little more transverse, less convex and more sparsely punctured; fore tibiae spur somewhat stouter and shorter; aedeagus Fig. 118-119 . Female: pronotum relatively less transverse, more convex and more densely punctured; fore tibiae spur somewhat slender and almost straight.
