Taxonomic history

Webbia pabo Sampson, 1922: 150.

Diagnosis

2.3−2.5 mm long (mean = 2.5 mm; n = 4); 3.29−3.57 times as long as wide. This species is distinguished by the circumdeclivital margin denticulate; declivital face bearing a large spine that is as broad at apex as base; acute spine at elytral apex arising from the sutural interstriae

May be confused with

Webbia biformis and W. diversicauda

Distribution

‘Borneo', China (Xizang, Yunnan), India (Madhya Pradesh, Uttarakhand), Indonesia (Maluku), East Malaysia, Thailand

Host plants

Associated with Dipterocarpaceae (Anisoptera, Dipterocarpus, Dryobalanops, Shorea) (Beaver and Browne 1975, Ohno 1990). The synonym, W. quadricinctus, has been recorded only from Castanopsis (Fagaceae) in New Guinea. The host change could be related to the relative rarity of dipterocarps in New Guinea relative to areas to areas west of Wallace’s line.
