forewings are browner than in the next two species, and the subapical costal
patch is evenly dark brown throughout rather than paler anteriorly. The
genitalia of all three species are very similar, with a very narrow valve, a
single angular process from the costa, and a sclerotised, triangular 'corema'.
The valve costal process in increnulata is much narrower than in bosca,
spine-like rather than triangular.
notes. D. bosca is typically from Burma and resembles more closely the next
species, with greyer forewings and a subapical costal patch that darkens towards
the posterior. In bosca this is very narrow, and the fine fasciae are
weak and more irregular.

species ranges from the lowlands to 2000m and is usually found in forested
areas. During the Mulu survey it was taken in lower and upper montane forest on
G. Mulu, but also in large numbers at 250m in dipterocarp forest on the lower
slopes of the limestone G. Api.
