Bertula bornedescripta
Figure 83

9-10mm. This and the next species bear some resemblance in facies to “Bleptina” descripta Leech from China (see p. 26 for comments on East Asian “Bleptina” species). This species, the smaller of the two, is the closest to descripta in its off-white markings on dark greyish brown, the forewing postmedial similarly angled, the antemedial oblique and the reniform a delicate white lunule, but descripta is slightly larger and the fasciae narrower and more clearly defined on all wings. The male labial palps are slender and similarly evenly recurved in front of the head, the third segment half the length of the second, but the antennae are more strongly fasciculate. The male genitalia have the valves rather trapezoid, with the oblique distal margin excavated. The aedeagus vesica has one densely spined diverticulum as well as general scobination.
