Host plants.

Recorded from Balanocarpus, Dipterocarpus, Dryobalanops and Shorea ( Dipterocarpaceae) (Beaver and Hulcr 2008).

Remarks.

A lectotype for the species was designated by Anderson and Anderson (1971: 12) as well as by Schedl who designated it a “holotype” (1979: 87). The citation by Schedl is invalid and unnecessary. Wood and Bright (1992: 828) mistakenly cited the Schedl designation. The lectotype is in NMNH and a paralectotype is in NHMW.
