Type material.

Holotype Webbia trigintispinata (NHMUK). Holotype Webbia mucronatus (NMNH).

Diagnosis.

3.0 mm long (mean = 3.0 mm; n = 5); 3.0 × as long as wide. This species is distinguished by the margin of declivity with 13-15 teeth on each side; declivital face with the vermiculate ridge on interstriae 1 strongly raised in middle of declivity, and with three or four rows of tubercles lateral to it; and elytral disc shiny to upper margin of declivity, apart from grooves between marginal teeth.

Host plants.

Associated with Dipterocarpaceae ( Dipterocarpus , Dryobalanops , Hopea , Shorea ) ( Beeson 1961; Ohno 1990).

Remarks.

The species name 26-spinatus is an incorrect original spelling which is here corrected to vigintisexspinata . The corrected name is a subjective synonym of Webbia trigintispinata . Images of the W. mucronatus holotype were examined by all authors and found to be conspecific with the W. trigintispinata holotype and non-type specimens. It is here placed in synonymy.
