Genus: Psyllotoxoides

Diagnostic Features
  • Description: Elongate-oblong, moderate-sized, about 19 mm in length. Integument generally dark brown with whitish, ferrugineous, brown, and ochraceous pubescence. Head with frons elongate, about as wide as width of two lower eye lobes. Eyes with lower lobes large, oblong. Genae transverse, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex or armed with a short, blunt horn; antennae distinctly longer than overall body length, as much as 1 1/3 times as long; scape gradually expanded at apex, longer than antennomere IV; antennomere III curved, longer than scape and antennomere IV. Pronotum transverse, conical, wider at apex, with lateral tubercles. Elytra with sides roughly parallel; elytral apices jointly rounded; elytra with distinct maculae; base of elytra with several prominent, shiny tubercles at humeri. Basal 1/3 of elytra without punctation. Procoxae without projection. Mesosternal process with apex feebly 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: distinctly large eyes; conical pronotum with lateral tubercles; and base of elytra with several prominent, shiny tubercles at humeri.

  • Similar genus/genera: superficially resembles Monneoncideres and Oncideres.
