Type locality. Camp Grant, San Pedro River, Arizona [ U.S.A.].

Type repository. Museum of Comparative Zoology. Harvard University, Cambridge. MA ( U.S.A.) (type not examined).

Redescription. Length 4.0–5.0 mm; moderately elongate; moderately convex, feebly shiny, glabrous. Red to dark brown; epistome and pronotal disc slightly darker; antennal club rufo-testaceous. Head with epistome slightly convex on disc, antero-medially depressed toward clypeal margin, densely almost evenly punctured, punctures somewhat coarser distally; clypeus broadly sinuate at middle, subangulate at sides, lateral margins regularly arcuate, thinly bordered, edge slightly raised, glabrous; genae obtusely round, shortly sparsely ciliate, protruding from the eyes; frontal suture barely distinct and faintly tuberculate; front evenly coarsely rather densely punctured. Pronotum transverse, moderately convex, not explanate at sides, coarsely and densely dually punctured; large punctures, two times larger than small, not denser on sides and lacking on disc; small punctures almost evenly scattered throughout; lateral margins feebly arcuate, rather thinly bordered, edge glabrous; hind angles obtuse; base regularly arcuate, thinly bordered. Scutellum somewhat convex, finely alutaceous, coarsely irregularly punctured on basal two thirds. Elytra feebly widened posteriorly; striae fine, moderately impressed, closely punc- tured, crenulate; interstriae almost flat, rather coarsely irregularly punctured. Hind tibiae upper spur shorter than first tarsal segment; latter almost as long as following three segments combined. Male: fore tibiae spur relatively stout, abruptly downward curved; head and pronotum more transverse, less convex and less densely punctured; metasternal plate distinctly excavate; aedeagus Fig. 39–40 View Figures 31–40 . Female: fore tibiae spur slender and feebly arcuate; head and pronotum narrower, more convex and more densely punctured; metasternal plate almost flat.
