Diagnosis. Bactra cophinana is related to several other Oriental species of Bactra , but it can be distinguished by the peculiar basket-shaped sternite 9 in the female genitalia.

Description. Male unknown. Female. Head: Frons and vertex pale brownish yellow. Thorax ( Fig. 20 ): Forewing length 6 mm; forewing yellow-brown, with scattered black scales and darker scales on veins creating a faint longitudinally striated pattern; a small pale dot between base of M 2 and M 1, surrounded by a darker V-shaped spot. Fringe paler than forewing and with black dots. Hindwing pale brown, somewhat darker distally, veins darker.

Abdomen: Genitalia ( Fig. 66 ) with papillae anales broad and flattened distally, very slender towards base; apophyses equal in length, about same length as ovipositor lobes; hind margin of sternite 7 deep concave, base of concavity folded, sterigma a broad and sclerotized V-shaped plate embraced by sternite 7, convex at base, arms medially swollen and folded, apical ends tapering, tops rounded; sternite 9 basket-shaped with horizontal ribbons; ductus bursae strongly widened distally, as long as corpus bursae; colliculum short, divided, covered by sterigma; corpus bursae ovoid, spined in distal ⅔; signa a small spined cup.

Distribution. Bhutan.

Etymology. The name cophinana is from the Latin cophinus, which means basket.
