Color. Yellowish brown to brown with black markings. Two spots on vertex, antennal cavities, apical half of clypellus, two large somewhat triangular spots on posterior half of pronotum not reaching hind margin, short median line between them, triangles at base of scutellum, black. Frontal sulci, median impressed line on scutellum, black. Hind margin of vertex behind eyes, black. Disc of scutellum brown, spot on either side of median impressed line paler. Forewings brownish hyaline. Female coloration similar to male but paler and black markings markedly reduced in size scutellum without black triangular spots at base.

Morphology. Face including eyes about as wide as long. Ocelli closer to adjacent eyes than to each other.

Male genitalia. Pygofer lobe produced caudo-ventrally and rounded, heavily sclerotized along dorsal margin. Inner arm of styles shorter than outer arm. Connective heavily pigmented, bilobed caudally. Aedeagus with atrium forming stage at base, shaft compressed, dorsally directed with apical gonopore and with ventrally directed short process on caudal margin near apex. Anal collar process well developed, forked near apex, dorsal fork shorter than ventral fork. Anal segment robust, anal style very small, rounded.

Female genitalia. Seventh sternite quadrangular, hind margin concave, with median triangular lobe with acute apex.

Measurements. Male 3.55 (3.40–3.70) mm long, 1.14 (1.08–1.20) mm wide across eyes. Female 3.94 (3.70– 4.10) mm long and 1.28 (1.22–1.32) mm wide across eyes.

Remarks. I. priyankae is distributed along the eastern part of the Sub-Himalayan region and is a common species there. It has a forked anal collar process as in I. violacea from Nilgiri Hills. It differs from I. violacea both in the structure of aedeagus and connective.
