 9mm. The facies is pale reddish fawn with only a hint of fasciation,
such as a whitish submarginal fascia. The discal spots are small black dots, but
there is no darker brown fasciation or punctuation on the veins as seen in most
other straw-coloured Bornean species such as ptyonopoda or sakuraii. The
male hind-tibia and tarsi are not significantly reduced, and well endowed with a
hair pencil and dense scaling. The male genitalia have the valves simple, gently
tapering to a rounded apex, lacking the sort of flanges, digitate processes or
enlarged subapical setae seen in other straw-coloured Bornean species. The
aedeagus is large, the vesica with a cluster of about twenty moderate cornuti
that increase slightly in size from one end to the other. In the female the
bursa is convolute with fine basal scobination and a ring of spines just distad
from the centre.
