Neotrichaphodioides new genus

Type species. Aphodius volxemi Harold, 1876 , by present designation.

Diagnosis. Small or medium size species (length 3.5-8.0 mm), oblong, moderately convex, few specimens are glossy, glabrous; rarely apical half of male elytra with short, dense pubescence. Piceous, brownish-red or brownish-yellow, sometimes elytra cloudy darkened on disc. Head with epistome almost flat, sparsely punctulate; clypeus almost semicircular or subtruncate anteriorly, widely rounded at sides, glabrous; genae acutely angulate or obtusely rounded, not to very shortly bristled, more or less strongly protruding; frontal suture finely impressed, mutic. Pronotum transverse, feebly convex, evenly or dually punctured; hind angles subtruncate; base not bordered. Scutellum small, triangularly elongate. Elytra oval, denticulate or not at shoulder, deeply finely striate; intervals flat or more or less strongly convex, microreticulate, sparsely punctured. Fore tibiae distally tridentate, proximally serrulate at outer margin; upper side sparsely distinctly punctured. Hind tibiae with feeble transverse carinae on outer face; apically fimbriate with spinules elongate and irregularly strongly unequal. Pygidium sparsely roughly punctured; each puncture with a short recumbent hair; apical margin with few, sparse and elongate straight setae. Sexual dimorphism shown in males mostly by wider head and pronotum, the short and widened segments of the labial palpi, elytral intervals sometimes with short dense pubescence, fore tibiae apical spur short, stout and abruptly bent downward, and metasternal plate deeply excavate, densely punctured and pubescent. Aedeagus with parameres short, with a preapical tuft of more or less elongate, sometimes exceptionally elongate hairs. Epipharynx with anterior margin deeply sinuate at middle, widely rounded at sides; epitorma shortly conical; corypha with two apical strong and elongate spiculae protruding beyond front margin; pedia densely pubescent, with few elongate, stout, antero-lateral spines subserially arranged; chaetopariae slender, moderately elongate and densely arranged.

Distribution. Neotropical Region.

Etymology. The generic name (gender masculine) is based on the first three letters of “Neotropical” followed by the generic name Trichaphodioides .
