Gonaphodioides newtoni new species

( Fig. 84-88 )

Type locality. 43 Km SW Huejutla, m 1500, Tlanchinol, Hidalgo, Mexico.

Type repository. Canadian National Collection, Ottawa, Canada.

Description. Length 4.0-4.5 mm; moderately elongate, rather convex, shiny, glabrous. Dark brown; clypeal margin, anterior angles of pronotum and elytral apex paler; legs dark reddish-brown; antennal club dirty testaceous. Head with epistome gibbous medially, evenly, not closely, distinctly punctured; clypeus feebly sinuate at middle, subangulose at sides, rather thickly bordered, edge glabrous, anteriorly moderately reflexed; genae obtuse, not ciliate, protruding from the eyes; frontal suture obsolete; front somewhat more sparsely punctured than epistome. Pronotum transverse, convex, simply, almost evenly, rather closely punctured; punctation somewhat denser on sides; lateral margins straight, faintly sinuate inwardly before hind angles, rather thickly bordered, edge glabrous; hind angles obliquely truncate, truncation slightly sinuate inwardly; base feebly bisinuate. Scutellum somewhat elongate, superficially alutaceous and sparsely punctured on basal half. Elytra elongate, subparallelsided, minutely denticulate at shoulder; striae fine, superficially, not closely punctured, not crenulate; interstriae almost flat, irregularly, sparsely finely punctured. Hind tibiae upper spur shorter than first tarsal segment; first tarsal segment as long as following four segments combined. Male: head and pronotum relatively more transverse, less convex and less densely punctured; metasternal plate with median longitudinal groove deeper; aedeagus Fig. 87-88 . Female: head and pronotum relatively less transverse, more convex and more densely punctured; metasternal plate with median longitudinal groove superficial.
