Two further species are represented by single males having genitalia
much as in the two previous species and sharing the grey and white facies of the
first four species discussed. The genitalic differences are slight, hence it
would be too risky to describe them as new. Material from Sumatra being studied
by Dr. R. Sato may enable their status to be clarified.
Slide 14218 (Sato slide RS-27 10) (Fig. 561). The facies is
similar to that of D. sugillata but the forewing border is more uniform
dark grey except for a large white patch at the centre of the margin. The
posterior two thirds of the hindwing border is only lightly marked, almost
white. The ventral margin of the valve is strongly convex, and the saccular
process is more tightly coiled than in other species. The extension of the
juxtal rod is long, slender. There is a weak pair of coremata between segments 3
The specimen is from lowland forest at Labi (30-60m) in Brunei. The
species is also known from Sumatra.
Slide 16406 (Fig. 562). The forewing markings are similar to
those of D. kerangatis, but the hindwing resembles that of the specimen
just described, apart from a grey (c.f. white) basal zone. The tongue-like
process from the tegumen is long. The valves are lenticular in shape, the
saccular process approximately as in D. submontana. The juxtal rod
is short, very slender.
The specimen is from 300m in the Ulu Temburong, Brunei. There may be
further material from Peninsular Malaysia in the FRIM collection.
