Diagnosis. Borneogena trashiyana is a broad winged, pale brown species. As is typical for the genus, the forewing has a sinuate costa and a deep concavity in the termen. From B. siniaevi Razowski, 2009 , B. trashiyana can be distinguished by the cup-shaped sterigma in the female genitalia. The sterigma in B. siniaevi is more or less rectangular. It can be distinguished from B. antigrapha Diakonoff, 1941 by the absence of the swollen sternite 8, characteristic of the latter.

Description. Male unknown. Female. Head ( Fig. 18 View FIGURES 1‒18 ): Pale brown, labial palpus about 1.5 times diameter of compound eye. Thorax: Forewing length 9 mm; forewing broad, costa straight to middle, then convex followed by a concavity before apex, pointed apically, termen with deep concavity beneath apex, in dorsal half convex; dorsum straight; markings most reduced, basal field indicated by darker scales, a dark band indicated from ⅓ of costa to ⅔ of dorsum, at concavity of costa a darker triangular spot. Fringe paler than forewing. Hindwings shiny white, overlaid with black scales. Fringe at tornus grey. Abdomen: Genitalia ( Fig. 65 View FIGURES 56‒70 ) with papillae anales moderate, apophyses very slender, apophyses posteriores slightly shorter than apophyses anteriores; sterigma a simple convex plate, ostium circular, sternite 7 with hind margin slightly concave; ductus bursae long, slightly broadening towards corpus bursae, folded at ⅓, in lower part punctuated; colliculum a long sclerotization in upper ⅓ of ductus; corpus bursae ovate, shorter than ductus bursae, punctuate, signum a short smooth thorn.

Distribution. Bhutan
