Taxonomic history

Webbia cornutus [sic] Schedl, 1942a: 183.

Diagnosis

1.9−2.2 mm long (mean = 2.02 mm; n = 5); 3.14−4.0 times as long as wide. This species is distinguished by the circumdeclivital margin denticulate, elytral declivity rather smooth and strongly shining, striae 1 and 3 very weakly impressed, interstriae without granules; strial and interstrial punctures very fine, of the same size, bearing short fine hairs; short acute elytral process arising from declivital margin; and elytral apex entire.

May be confused with

Webbia turbinata

Distribution

‘Borneo’, East & West Malaysia, Thailand

Host plants

associated with Dipterocarpaceae (Dipterocarpus, Hopea, Shorea) (Browne 1961b, Beaver and Browne 1975, 1979)

Remarks

As in W. biformis, brood size can be large (up to 87) (Beaver and Browne 1978). The majority of the records from Thailand listed under this species by Beaver et al. (2014) should be transferred to W. turbinata Maiti and Saha. The records from the southern provinces of Chumphon and Nakhon Sri Thammarat are correct.
