Type locality. Las Joyas, m 1870, Sierra de Manantlán, Jalisco, Mexico.
Type repository. Essig Museum of Entomology, Berkeley, California, U.S.A.
Description. Length 5.0-5.5 mm; oblong, convex, moderately shiny but elytra on preapical declivity dull, glabrous. Dark reddish-brown, clypeal margin, pronotal anterior angles and preapical declivity of elytra paler; legs brown-reddish; antennal club dark brownish. Head with epistome weakly convex on disc, coarsely, rather densely, subregularly punctured; clypeus faintly sinuate at middle, round at sides, rather thickly bordered, edge faintly upturned, very shortly sparsely bristled; genae obtusely round, very shortly ciliate, feebly protruding from the eyes; frontal suture very finely impressed; front relatively more sparsely and less coarsely punctured than epistome. Pronotum moderately transverse, convex, almost subparallel-sided; somewhat irregularly punctured; punctation coarser and denser on sides, sparser and more superficial on disc; lateral margins very finely bordered and faintly inwardly sinuate before hind angles; hind angles widely truncate; truncature slightly sinuate inwardly; base bisinuate. Scutellum elongate, sparsely irregularly punctured on basal half. Elytra slightly broadened posteriorly, distinctly denticulate at shoulder; striae very fine, superficially punctured, subcrenulate; interstriae nearly flat, finely microreticulate basally and on disc thus few shiny, more strongly microreticulate on preapical declivity thus dull, distinctly sparsely punctured. Hind tibiae upper spur as long as two thirds of first tarsal segment; first tarsal segment somewhat shorter than following four segments combined. Male: pronotum not narrowed anteriorly; fore tibiae spur relatively stouter and abruptly downward bent; metasternal plate longitudinally excavate at middle; aedeagus Fig. 26-27. Female: pronotum somewhat narrowed anteriorly; fore tibiae spur relatively slender and almost straight; metasternal plate nearly flat.
