Gonaphodiopsis hypogea new species

( Fig. 109-113 )

Type locality. Salamander Cave, Gomes Farias, Rancho del Cielo, 3700’, Tamaulipas, Mexico.

Type repository. Canadian Museum of Nature (Howden Collection), Ottawa, Canada.

Description. Length 5.0-5.5 mm; shortly oblong, strongly convex, shiny, glabrous. Dark chestnut brown to blackish; clypeal margin paler; legs more or less dark brown; antennal club testaceous. Head with epistome feebly gibbous medially, slightly depressed anteriorly, rather finely, not closely, evenly punctured; clypeus feebly sinuate at middle, round at sides, very finely bordered, edge glabrous; genae obtusely round, not ciliate, protruding from the eyes. Pronotum strongly convex, moderately transverse, dually punctured and with a transverse belt of large, deep and contiguous punctures crenulating a sort of thick edge close to basal margin; large, coarse punctured, six to seven times larger than small ones, irregularly, rather closely scattered on sides, lacking on disc; small, very fine punctures evenly sparse throughout; lateral margins almost parallel, inwardly sinuate before hind angles, rather thickly bordered, edge glabrous; hind angles broadly truncate; truncation distinctly inwardly sinuate; base feebly bisinuate. Scutellum elongate, flat, sparsely finely punctured. Elytra widened posteriorly, strongly convex, strongly denticulate at shoulder, deeply striate; striae rather fine, coarsely, not closely punctured, crenulate; interstriae convex on disc, subcariniform on preapical declivity, very finely, sparsely punctured. Hind tibiae upper spur shorter than first tarsal segment; first tarsal segment distinctly longer than following three segments combined. Male: pronotum relatively less coarsely and less densely punctured; aedeagus Fig. 112-113 . Female: pronotum relatively more coarsely and more densely punctured.
