Additional material examined. 1♀ / incusans / Wlk. / Ceylon / merid. Fruhst. // Zoologisches Museum / Univeristat Greisfwald /.

Measurements. Female (n=2): forewing length: 30–34 mm, width: 7–8 mm; hindwing length: 27–30 mm, width: 6–7 mm.

Diagnostic characters. Vertex and frons with long hairs. Frons shiny brown with long brown and white hairs. Clypeus and labrum dominantly brown. In males, antennal segment 1 at least as long as segments 2–3 together. Basal segments slightly curved with 3–5 segments with teeth and other segments nodulated with short bristles. Antenna not reaching pterostigma. Mesothorax with wider distinct yellow band, metathorax with narrower distinct yellow band in lateral view. Apices of wings rounded. Pterostigma brown. Legs reddish brown. Male ectoproct processus short and as wide as width of ectoproct curving downward and inward in lateral view. Sternite 9 triangular, significantly wider at base than high, tip hood-like. Gonocoxite 9 arched and with pair of wide curved horn-shaped extensions, apices acute, wider at base with slight protrusion inwards. Terminalia and genitalia as in Kimmins (1949: figs 8–9).

Distribution. Sri Lanka ( Kimmins 1949), India (Karnataka, Maharashtra, Odisha) ( Fraser 1922) ( Fig. 21 View FIGURE 21 ).

Flight period of adult. Active during the months of August and September in India ( Fraser 1922), March, April, June, October, and November in Sri Lanka ( Kimmins 1949) ( Fig. 22 View FIGURE 22 ).

Remarks. This species was described from Sri Lanka ( Ceylon) ( Walker 1853). The type specimen of G. nugax is a female and G. incusans is a male. McLachlan (1873a) was able to correctly determine that they belonged to the same species. Its occurrence in India was first documented by Fraser (1922), but he considered his determination uncertain. Since then, no new faunistic data from India have become known ( Ghosh & Sen 1977; Sharma & Chandra 2012, 2013). The occurrence of the species in India must be confirmed to validate earlier accounts.
