Igerna sikkima sp. nov.

Figs 72, 360–368.

Color. Ochraceous with dark brown to black markings on head and pronotum ( Figs 360 and 361). Forewings chocolate brown with claval suture and commissure ochraceous, apices of forewings paler. Legs ochraceous with chocolate brown markings.

Morphology. Face including eyes wider than long. Ocelli closer to adjacent eyes than to each other.

Male genitalia. Caudal lobe of pygofer turned mesally with distal stout spines. Connective longer than broad with bifid distal margin. Aedeagus with forked process on preatrium, forks divergent about as long as shaft, shaft more or less of uniform width with pair of lamellate processes having serrated margins at midlength; gonopore on dorsal margin near apex; shaft with spicules in apical quarter and also along gonopore; dorsal apodeme well developed. Anal collar process with simple dorsally directed process hook-like.

Measurements. Male 3.6–3.8 mm long, 1.10–1.11 mm wide across eyes.

Material examined. HOLOTYPE ♂, INDIA: Sikkim: Gangtok , 2123 m, 9.vi.2005, C.A. Viraktamath ( UASB) . PARATYPES: INDIA: Sikkim: 10 ♂, same data as holotype ; 1 ♂, West Bengal: Kalimpong , 1780 m, 6.vi.2005, C.A. Viraktamath ( BMNH, NPC, NMNH, ZSI, UASB) .

Remarks. I. sikkima is similar to I. darjeelingensis but differs in the structure of the aedeagus. It lacks the apical processes present in I. darjeelingensis but has a lamellate process at midlength of shaft. Both species occur in the same habitat and were swept from grassland mixed with herbs in Sikkim along with specimens of I. keyae sp. nov.
