March 2026: Since the original publication of this tool, one new species of Peritrox Bates, 1865Bates, 1865:
Bates HW. 1865. Contributions to an insect fauna of the Amazon Valley. Coleoptera: Longicornes. The Annals and Magazine of Natural History 3(15):213–225, 382–394; 3(16):101–113, 167–182, 308–314. was described (Nearns and Swift 2019Nearns and Swift 2019:
Nearns EH, Swift IP. 2019. Three new species of longhorned beetles (Coleoptera: Cerambycidae) from Central and south America. The Pan-Pacific Entomologist. 95(3/4):147-158.). This species is added to "Included Species". Other sections in this fact sheet have not been edited to account for the new species.
Elongate-oblong, small to moderate-sized, ranging from about 10–15 mm in length. Integument generally dark brown or black with whitish, ferrugineous, black, and ochraceous pubescence. Head with frons elongate, about as wide as width of 1 1/2 lower eye lobes. Eyes with lower lobes large, oblong. Genae subquadrate to elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, narrowly separated, contiguous at base; tubercles armed with short, blunt horn. Antennae distinctly longer than overall body length, as much as twice as long; scape gradually expanded to apex, about as long or shorter than antennomere IV; antennomere III nearly straight or curved, longer than scape and antennomere IV; antennomere XI shorter than X (females) or longer than X (males). Pronotum transverse, roughly conical, wider at base, with or without lateral tubercles. Elytra with sides roughly parallel; elytral apices individually rounded; elytra generally uniform in coloration or speckled; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with sparse to dense punctation, surface finely punctate, coarsely punctate, or granulate-punctate. Procoxae without projection or with an obtuse tubercle. 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: large eyes; narrowly separated antennal tubercles, contiguous at base; scape gradually expanded to apex; roughly conical pronotum; and elytra with sides roughly parallel.
