Genus: Pseudobeta

• Description: Elongate-oblong, small to moderate-sized, ranging from about 10–17 mm in length. Integument generally dark brown or black with whitish, ferrugineous, and ochraceous pubescence. Head with frons subquadrate to elongate, about as wide as width of two lower eye lobes. Eyes with lower lobes oblong. Genae subquadrate to elongate, about as tall to distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn; antennae about as long as overall body length, or as much as 1 2/3 times as long; scape clavate, about as long or shorter than antennomere IV; antennomere III sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to conical, wider at base, with or without lateral tubercles. Elytra with sides roughly parallel; elytral apices individually rounded; elytra 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 small acute projection or with distinct, curved hook. Mesosternal process with apex subtruncate to deeply emarginate. 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: widely separated eyes; subquadrate to elongate frons; sinuate antennomere III; and elytra with sides roughly parallel.


• Similar genus/genera: superficially resembles Hesychotypa, Ischiosioma, and Prohylus.
