A single female with facies similar to that of copiosa and
zygophyxia was taken by Dr Chey Vun Khen in a Pinus caribaea plantation
at Brumas near Sabah, together with B. copiosa. The genitalia have the
lamella postvaginalis modified, the ostium broad, setae, and there is a large
signum in the bursa. It probably represents a distinct species: a single female
(slide 17868) from Sumatra (illustrated) has also been located.
