Type locality. 8 miles South of Somerset, Texas [ U.S.A.].

Type repository. California Academy of Sciences. San Francisco (paratype examined).

Redescription. Length 3.0– 3.5 mm; moderately elongate, convex, subshiny, pubescent. Brown; clypeal margin and pronotal sides paler; legs reddish brown; antennal club brownish. Head with epistome feebly convex, closely moderately granulate throughout, alutaceous between granules, distally with nearly imperceptible hairs; granulation somewhat confused proximally; clypeus subsinuate at middle, broadly round at sides, thinly bordered, edge glabrous and slightly reflexed; genae broadly round, sparsely shortly ciliate, moderately protruding from the eyes; frontal suture medially obsolete, feebly raised laterally; front coarsely, rather confusedly rugose. Pronotum transverse, convex, feebly depressed near anterior and posterior angles, simply, coarsely punctured throughout; large, umbilicate punctures contiguous and, mainly laterally, with short recumbent hairs; lateral margins feebly arcuate, thickly bordered, edge glabrous; hind angles obtusely round; base feebly bisinuate, finely somewhat irregularly bordered. Scutellum strongly alutaceous, irregularly punctured. Elytra convex, moderately elongate, slightly wider posteriorly; striae geminate, few deep, finely, not closely punctured, faintly crenulate; interstriae slightly convex, strongly alutaceous, with extremely fine sharp border on each side and with double longitudinal row of close, coarse punctures bearing recumbent hairs moderately long. Hind tibiae superior spur somewhat shorter than first tarsal segment; latter as long as following two segments combined. Male: inferior spur of middle tibiae shortened, slightly bent inwardly, truncate apically; aedeagus Fig. 14–15 . Female: inferior spur of middle tibiae rather elongate, and regularly acuminate.

Material examined. U.S.A.: Texas: 8-mi South of Somerset , 10.I.1940, leg. A. J. Kirn & E. S. Ross, from Geomys burrow (2 exx., paratypes, DCGI) ; idem, 27-29.XI.1942, leg. A. J. Kirn, from Geomys burrow (1 ex., paratype, DCGI) ; idem, 28.XI.1942, leg. A. J. Kirn, from Geomys burrow (1 ex., paratype, DCGI) ; idem, 27.XII.1942, leg. E. S. Ross, from Geomys burrow (2 exx., paratypes, DCGI) .

Distribution. U.S.A. (Arkansas, Kansas, Louisiana, Texas).

Bionomics. Late autumn and winter species often collected from burrows of pocket gophers, Geomys spp. . Kovarik et al. (2008), Tishechkin and Cline (2008), Connior (2011), and Connior et al. (2014) report on more recent collections in pocket gopher burrows in Arkansas and Louisiana.
