Nearns EH, Tavakilian G-L. 2012b. A new genus and five new species of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) from South America, with notes on additional taxa. Insecta Mundi. 0266:1–23.). These species are added to "Included Species". Other sections in this fact sheet have not been edited to account for the new species.
Elongate to elongate-oblong, small to moderate-sized, ranging from about 10–19 mm in length. Integument generally dark brown or black with whitish, black, brown, ferrugineous, and ochraceous pubescence. Head with frons subquadrate to elongate, about as wide as width of 2 1/2 lower eye lobes. Eyes with lower lobes oblong. Genae variable in shape, from subquadrate to elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn, or with a moderately long, blunt horn or large blunt process. Antennae about as long as overall body length, or as much as twice as long (males); scape clavate, shorter than antennomere IV; antennomere III variable in shape, from nearly straight to curved to sinuate, longer than scape and about as long or longer than antennomere IV; antennomere XI shorter than X (females) or longer than X (males). Pronotum subquadrate to transverse, roughly cylindrical to conical, distinctly narrower at base, with or without lateral tubercles. Elytra with sides roughly parallel to slightly attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled, or with distinct maculae; base of elytra without tubercles or with two 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 or with distinct, curved hook (males). 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: moderately large eyes; elytra with sides roughly parallel to slightly attenuate; and short metafemora.
Superficially resembles Apocoptoma, Chitron, and Leus.
Lesser Antilles (Grenada, Guadeloupe, Martinique); Central America (Nicaragua to Panama); South America (Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Paraguay, Peru, Suriname, Trinidad & Tobago)
Apocynaceae (Forsteronia thyrsoidea); Elaeocarpaceae (Sloanea massoni); Fabaceae (Acacia tortuosa, Cajanus cajan, Inga ingoides, Lonchocarpus sp.); Lauraceae (Persea americana [avocado]); Moraceae (Ficus pertusa)
