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 denticulatedenticulate:
covered in denticles
; declivitaldeclivital:
pertaining to the elytral declivity
face bearing a large spinespine:
an elongate projection of the exoskeleton that is longer than its basal width
that is as broad at apexapex:
point or edge furthest from the body; opposite of base
as basebase:
point or edge closest to the body; opposite of apex
; acute spinespine:
an elongate projection of the exoskeleton that is longer than its basal width
at elytralelytral:
pertaining to the elytra
apexapex:
point or edge furthest from the body; opposite of base
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 1975Beaver and Browne 1975:
Beaver RA, Browne FG. 1975. The Scolytidae and Platypodidae (Coleoptera) of Thailand, a checklist with biological and zoogeographical notes. Oriental Insects 9: 283-311. https://doi.org/10.1080/00305316.1975.10434499, Ohno 1990Ohno 1990:
Ohno S. 1990. The Scolytidae and Platypodidae (Coleoptera) from Borneo found in logs at Nagoya port 1. Research Bulletin of the Plant Protection Service, Japan 26: 83-94.). 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.
