Gonaphodioides skelleyi new species

( Fig. 99-103 )

Type locality. San Juan Chamula env., 16°46’56.4’’– 092°41’36.3’’W, m 2282, Chiapas, Mexico.

Type repository. Dellacasa Collection, Genoa, Italy.

Description. Length 5.0-6.0 mm, oblong, rather convex, moderately shiny, glabrous. Black; tarsi and antennal club dark piceous. Head with epistome feebly convex on disc, finely, evenly, not closely punctured throughout; clypeus faintly sinuate at middle, obtusely round at sides, finely bordered, edge glabrous, moderately reflexed; genae obtusely round, not ciliate, feebly protruding from the eyes; frontal suture obsolete; front almost evenly finely, rather sparsely punctured. Pronotum transverse, convex, dually punctured; large punctures, five to six times larger than small ones, sparsely irregularly scattered on sides only; small, very fine punctures evenly not closely sparse throughout, medially extremely fine; lateral margins feebly arcuate, rather thickly bordered, edge glabrous; hind angles obliquely truncate, truncation feebly inwardly sinuate; base distinctly bisinuate. Scutellum slightly convex, finely irregularly punctured on basal half. Elytra oval-elongate, feebly broadened posteriorly, minutely denticulate at shoulder; striae fine, superficially, not closely punctured, faintly crenulate, somewhat deeper on preapical declivity; interstriae flat, near imperceptibly alutaceous and with extremely fine sparse punctures. Hind tibiae upper spur shorter than first tarsal segment; first tarsal segment somewhat longer than following three segments combined. Male: head and pronotum relatively more transverse, less convex and more sparsely punctured; aedeagus Fig. 102-103 . Female: head and pronotum relatively less transverse, more convex and somewhat more closely punctured.
