Color. Vertex with median stripe continued on face and meeting broad band between and enclosing ocelli, two lateral round spots, clypeus, clypellus, gena except proximal outer margin below eyes, lorum, pronotum except two obscured brownish spots on disc and ochraceous lateral and posterior margins, scutellum anterior to median impressed line, thoracic pleurites and abdominal sternites, black. Antennal cavity shining black. Legs, basal 0.33 of clavus, basal 0.66 of forewing, fuscous; rest of face, vertex, scutellum and forewings ochraceous.

Morphology. Face including eyes wider than long, uniformly smoothly rounded in front, slightly depressed between ocelli. Ocelli closer to adjacent eye than to each other.

Male genitalia. Height of pygofer more than length, caudo-dorsally produced into narrow strongly curved process with stout spine on mesal margin about midlength and two sub-equal stout spines at apex. Subgenital plates triangular, with rounded angles, without macrosetae and extending beyond pygofer. Styles with inner arm curved laterally and posteriorly, slender, pointed and slightly longer than outer arm. Connective heavily pigmented, broad in middle, bearing anterior median round lobe and two distal somewhat quadrate lobes. Aedeagus with well developed dorsal apodeme, preatrium well developed with pair of dorsally directed processes appearing U-shaped in caudal view; shaft compressed with pair of teeth proximally on dorsal margin, apically with asymmetrically curved process and with short process on caudal margin, gonopore terminal. Ninth tergum membranous except for anterior sclerotised narrow band. Tenth segment anteriorly poorly sclerotised and posteriorly stout. Anal collar laterally broad, margins sinuate, apically attenuated.

Measurements. Male 4.2 mm long and 1.27 mm wide across eyes.

Material examined. INDIA: HOLOTYPE ♂, West Bengal: Darjeeling, Tiger Hill, 27.iv.1938, T.C. Maa ( BPBM) . PARATYPES: INDIA: Sikkim: 2 ♂, 2 ♀, Gangtok , 2123 m, 9.vi.2005, C.A. Viraktamath ( UASB) .

Remarks. I. darjeelingensis can be distinguished by its slightly asymmetrical aedeagus, peculiar pygofer and by the structure of the anal collar process.
