Microperus nugax (Schedl) comb. n.

Xyleborus nugax Schedl, 1939

Coptodryas nugax (Schedl): Wood and Bright 1992

Specimens examined.

Malaysia, Selangor (lectotype, BMNH); Malaysia, Selangor (Schedl det., BMNH); Malaysia, Sabah, Danum Valley, (13, Hulcr det., MSUC).

Diagnosis.

Very similar to Microperus diversicolor (e.g., antennal club type 3), except pronotum bright yellow with brown patch, elytra black, declivity commencing closer to elytral base, declivital interstriae covered with many small sharp hooks (similar as in Microperus parva, but larger). Characteristic elytral disc: anterior portion inflated, convex, boundary between elytral disc and declivity slightly concave, impressed.

Comments.

Schedl (1979) designated lectotype in NHMW, another unspecified “type” resides in BMNH. Possibly synonymous with Coptodryas undulata (Sampson) (as Xyleborus leprosulus Schedl, syn. Wood 1989) (Schedl 1939).

Biology.

Creates irregularly branching galleries with transverse brood chambers (Beaver and Browne 1978).
