( Fig. 16–20 )

Geomyphilus geronimo Gordon and Skelley, 2007: 405 .

Type locality. 8 mi. SE of Portal State line Rd. at Portal Rd., 4400 ft., Cochise Co., Arizona [ U.S.A.].

Type repository. Florida State Collection of Arthropods. Gainesville, Florida, U.S.A. (holotype examined).

Redescription. Length 4.5–5.0 mm; oval elongate, convex, weakly shiny, almost glabrous. Yellowish brown; head, pronotum and elytral suture reddish brown; legs yellowish; antennal club testaceous. Head with epistome weakly gibbous on disc, moderately depressed medially toward clypeal margin, densely coarsely evenly punctured on disc, punctation confusedly rugose distally; clypeus rather deeply sinuate at middle, round at sides, finely bordered, edge upturned, extremely shortly sparsely bristled; genae obtusely round, sparsely elongately ciliate, protruding from the eyes; frontal suture finely impressed, somewhat gibbous laterally and medially; front coarsely densely almost evenly punctured. Pronotum transverse, convex, slightly alutaceous, somewhat depressed laterally near posterior angles, irregularly densely punctured; punctures larger on sides, contiguous in posterior depression, becoming smaller and more superficial on disc; lateral margins feebly arcuate, rather thickly bordered, edge shortly sparsely ciliate; hind angles obtusely round; basal margin evenly arcuate, distinctly bordered. Scutellum coarsely irregularly punctured on basal half. Elytra almost parallel-sided, strongly convex, slightly alutaceous thus moderately shiny; striae fine, distinctly punctured, feebly crenulate; interstriae weakly convex, densely finely irregularly punctured, sparsely extremely shortly haired on preapical declivity. Hind tibiae upper spur shorter than first tarsal segment; latter shorter than following three segments combined. Male: fore tibiae spur thickened, sinuately elongate, abruptly downward bent; inferior spur of middle tibiae short, strong, apically truncate and with a small inner tooth; aedeagus Fig. 19–20 . Female: fore tibiae spur not thickened and almost straight; inferior spur of middle tibiae regularly elongate, slender and apically acuminate.
