New record. Narathiwat Province, Hala-Bala Wildlife Sanctuary , tropical lowland forest, ethanol baited trap, 01.iii.2015 (7), Wisut Sittichaya (7, WSTC) .

Diagnosis. 1.98–2.11 mm long (mean = 2.04 mm; n = 5); 2.86–3.20× as long as wide (mean = 3.03 mm; n = 5). This species is distinguished by the declivity abruptly truncate, matt, circumdeclivital margin armed by granules, stronger, tuberculate and distinctly separated on interstriae 1–3; face with three striae visible, striae 1‒2 impressed, interstriae 1 strongly raised in lower half of declivity forming a pair of large, laterally compressed spinelike tubercles, interstriae 2‒3 raised, rugose in upper half of declivity, becoming uniseriate granulate in lower half.

The species is very similar to W. bituberculata (see above), but easily distinguished by the large, spine-like tubercles placed close together on interstriae on the lower part of the elytral declivity, as opposed to a pair of widelyseparated, small, tubercles in the middle of the declivity in W. bituberculata .

Distribution. East and West Malaysia. New to Thailand (Narathiwat).

Host plants. Dipterocarpus borneensis , Hopea spp ., Shorea maxwelliana (all Dipterocarpaceae ) ( Beaver & Browne 1979).
