Neohylus

Diagnostic Features

Description

Elongate-ovate, robust, moderate-sized, about 20 mm in length. Integument generally dark brown or black with whitish, ferrugineous, black, and ochraceous pubescence. Head with frons elongate, narrow, less than the width of one lower eye lobe. Eyes with lower lobes large, ovate-oblong. Genae subquadrate to transverse, distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately to narrowly separated; tubercles not armed at apex or armed with a short, blunt horn. Antennae distinctly shorter than overall body length, or as much as 1 2/3 times as long; scape clavate, longer than antennomere IV; antennomere III sinuate, about as long or longer than scape and longer than antennomere IV. Pronotum transverse, strongly conical, wider at base, without lateral tubercles. Elytra with sides attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled, or with distinct maculae; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate punctation, surface granulate-punctate; punctures distinctly large. Procoxae with small acute projection, an obtuse tubercle, or with distinct, curved hook. Mesosternal process with apex deeply emarginate. Metafemora moderate in length, about 1/3 as long as elytra.

Diagnosis

The combination of the following characters will help to distinguish this genus: large eyes, narrowly separated; distinctly sinuate antennomere III; strongly conical pronotum, without lateral tubercles; base of elytra with two prominent tubercles at humeri; and distinctly large punctation at basal 1/2 of elytra.
