Genus: Xylomimus
Diagnostic Features
- Description: Elongate, small sized, about 10 mm in length. Head with frons elongate, about as wide as width of 2–3 lower eye lobes. Eyes with lower lobes small, ovate. Genae elongate, distinctly taller than lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles armed at apex with small projection; antennae slightly shorter than overall body length; scape gradually expanded to apex, longer than antennomere IV; antennomere III nearly straight, longer than scape and antennomere IV, densely fimbriate beneath. Pronotum elongate, roughly cylindrical to slightly conical, slightly narrower at base, with small, lateral, blunt tubercles. Elytra with sides roughly parallel; elytral apices individually rounded; elytra with vague, pale vittae; base of elytra without prominent tubercles. Basal 1/3 of elytra moderate punctation, surface coarsely punctate. Procoxae without projection (females), condition unknown in males. Mesosternal process subtruncate. Metafemora distinctly short in length, about 1/5 as long as elytra.
- The combination of the following characters will help to distinguish this genus: distinctly elongate form; small eyes, widely separated; antennomere III densely fimbriate beneath; elytra with sides roughly parallel; and metafemora distinctly short.
- Similar genus/genera: superficially resembles Cacostola, however Xylomimus is much less elongate.
