Elongate-oblong, moderate-sized, ranging from about 13–21 mm in length. Integument generally dark brown or black with whitish, ferrugineous, and ochraceous pubescence. Head with frons subquadrate to transverse, about as wide as width of four lower eye lobes. Eyes with lower lobes distinctly small, ovate. Genae elongate, distinctly taller than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex or armed with a small projection. Antennae about as long as overall body length, or as much as twice as long; scape clavate, about as long or shorter than antennomere IV; antennomere III nearly straight or curved, longer than scape and antennomere IV, densely fimbriate beneath; antennomere XI shorter than X (females) or longer than X (males). Pronotum transverse, roughly cylindrical to conical, narrower at base, with lateral tubercles. Elytra with sides roughly parallel; elytral apices individually or jointly rounded; elytra generally uniform in coloration or speckled, or with distinct maculae; base of elytra without tubercles or with two or more prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface coarsely punctate or granulate-punctate. Procoxae without projection or with an obtuse tubercle. Mesosternal process with apex subtruncate to feebly emarginate. Metafemora short to distinctly short in length, about 1/4–1/5 as long as elytra.
The combination of the following characters will help to distinguish this genus: distinctly small eyes, widely separated; antennomeres III and IV densely fimbriate beneath; elytra with sides roughly parallel; and short metafemora.
Strongly resembles Microcanus, Oncideres, and Periergates.
North America (USA); Central America (Mexico to Nicaragua)
NOTE: Although Taricanus truquii has been reported from USA, this is believed to be an error (J.E. Wappes, pers. comm.).
