Trichonotuloides hansferyi new species

( Figures 11–15 )

Type locality. Los Laureles, Ixhuacán de los Reyes, Veracruz, Mexico.

Type repository. Dellacasa Collection. Genoa, Italy.

Description. Length 4.5–6.0 mm; oval-elongate, convex, subopaque; head almost glabrous, pronotum and elytra shortly densely pubescent. Blackish, clypeal margin shadowy brownish-red; legs dark brown; antennal club fuscous. Head with epistome slightly gibbous on disc, coarsely, densely, somewhat irregularly punctured; clypeus faintly sinuate at middle, round at sides, rather thickly bordered, edge slightly reflexed, shortly sparsely bristled; genae almost round, sparsely ciliate, feebly protruding from the eyes; frontal suture subcariniform, faintly gibbous medially and at sides; front coarsely, densely, somewhat irregularly punctured. Pronotum transverse, convex, simply, coarsely, very densely punctured; each carious and feebly umbilicate puncture with a short recumbent seta; lateral margins moderately arcuate, thickly bordered, edge very shortly sparsely bristled; hind angles broadly obtusely round; base almost regularly arcuate, rather thinly bordered. Scutellum excavate, coarsely punctured on basal half, punctures with short recumbent setae. Elytra elongate, moderately convex, feebly widened posteriorly, with epipleural carina very distinct at shoulder, shortly and rather sparsely bristled; deeply striate; striae, on disc, feebly crenulate, punctures rather close, slightly umbilicate, canaliculate and almost impunctate toward apex; interstices flat, coarsely, densely, evenly punctured, each puncture with short recumbent seta. Fore tibiae spur slender and acuminate in both sexes. Hind tibiae upper spur as long as first tarsal segment; latter as long as following two segments combined. Male: frontal suture relatively more raised; pronotum less convex and not narrowed anteriorly; metasternal plate concave and marginally pubescent; aedeagus Fig. 14–15 . Female: frontal suture almost obsolete; pronotum relatively more convex and somewhat narrower anteriorly; metasternal plate almost flat, glabrous.
