Genus: Oncioderes

• Description: Elongate-oblong, moderate to large-sized, ranging from about 10–22 mm in length. Integument generally dark brown or ferrugineous with whitish, ferrugineous, and ochraceous pubescence. Head with frons subquadrate, about as wide as width of 2 1/2 lower eye lobes. Eyes with lower lobes oblong. Genae transverse, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex; antennae about as long as overall body length, or as much as 1 1/3 times as long; scape gradually expanded to apex, about as long or longer than antennomere IV; antennomere III nearly straight or curved, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical, with or without lateral tubercles. Elytra with sides roughly parallel; elytral apices individually rounded; elytra generally uniform in coloration or speckled; base of elytra without tubercles or with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface finely punctate or coarsely punctate. Procoxae without projection. Mesosternal process with apex subtruncate. Metafemora moderate to short in length, about 1/3–1/4 as long as elytra.


• The combination of the following characters will help to distinguish this genus: moderately large eyes; subquadrate frons; gradually expanded scape; strongly transverse, roughly cylindrical pronotum; and elytra with sides roughly parallel.


• Similar genus/genera: strongly resembles some species of Lochmaeocles and Oncideres.
