Type locality. Yungas de Arepucho, Sihuencas, m 2200-2500, Bolivia.

Type repository. National Museum, Prague, Czech Republic (type not examined).

Redescription. Length 5.5-6.0 mm, elongate, moderately convex, shiny, glabrous. Chestnut-brown; clypeal margin and sides of pronotum shadowy reddish; legs brown-reddish; antennal club testaceous. Head with epistome feebly gibbous on disc, rather finely and regularly punctured, punctation distally near imperceptible due to strong microreticulation; clypeus faintly sinuate at middle, angulate, subangulate or, rarely, obtusely round at sides, very finely bordered, edge glabrous; genae obtuse, very shortly ciliate, protruding from the eyes; frontal suture finely impressed and widely curved backward at middle; front relatively more coarsely and densely punctured. Pronotum transverse, rather coarsely and subregularly punctured; punctation laterally and basally somewhat denser; lateral margins distinctly bordered, edge glabrous; hind angles widely truncate, truncature inwardly sinuate; base bisinuate. Scutellum ogival, elongate, shiny, near imperceptibly punctured basally. Elytra elongate, subparallel-sided, with humeral denticle rather strong; striae deep, somewhat wide, distinctly punctured, feebly crenulate; interstriae nearly flat, almost imperceptibly punctured. Hind tibiae upper spur a quarter shorter than first tarsal segment; first tarsal segment somewhat longer than following four segments combined. Male: fore tibiae relatively slender and more elongate, their spur short, stout and abruptly downward bent; aedeagus Fig. 71-72 . Female: fore tibiae relatively more short and stout, their spur slender, elongate and outward curved.
