Igerna delineata sp. nov.

Figs 312–316.

Color. Pale ochraceous. Two somewhat round spots on vertex, often joined by transverse band on hind margin of vertex of same color, inverted Y on upper part of face often encircling ocelli, two sub-marginal bands on frontoclypeus, clypellus excepting base, antennal pits, lateral frontoclypeal sulci, black. Antennae pale fuscous. Two large round spots on posterior margin of pronotum, median inverted cone shaped spot touching posterior margin of vertex, two lateral spots (often all three joined forming an anterior band), black. Two triangular spots at base of scutellum and median impressed line, black, latter connected to basal triangles by black line. Thoracic pleura fuscous. Forewings whitish with brown stripes on clavus and on main longitudinal veins. Head, thorax and abdomen often covered with waxy powder.

Morphology. Elongate, slender species, face slightly longer than broad, ocelli closer to each other than to adjacent eye, lateral margins of gena almost straight, lora elongate, apical half of clypellus depressed and flat.

Male genitalia. Pygofer with caudo-dorsal short blunt lobe. Subgenital plates comparatively short. Connective dark brown, slightly broader than long, caudally excavated in middle. Aedeagus with dorsal apodeme and socle strongly developed, shaft terminating in pair of ventrally directed forked processes, mesal fork may or may not overlap and each bear tooth on outer margin, gonopore apical.

Female genitalia. Caudal margin of seventh sternite slightly concave in middle.

Measurements. Male 5.36–5.73 mm long, 1.39–1.42 mm wide across eyes. Female 5.90–6.18 mm long and 1.39–1.56 mm wide across eyes.

Material examined. HOLOTYPE ♂, INDIA: Tamil Nadu: Kodaikanal , v.1916, T.V. Campbell, Brit. Mus., 1912-171 ( BMNH) . PARATYPES: INDIA: Tamil Nadu: 7 ♂, 2 ♀, same data as holotype ; 4 ♂, 7 ♀, same data as holotype except vi.1917 ( BMNH) ; 2 ♂, 7 miles (11.20 km) NW Pykara , 6500 ft (1972 m), 12.iii.1962, E.S. Ross and D.Q. Cavagnaro ( CAS) ; 12 ♂, 3 ♀, Dodabetta , 2670 m, 4.vi.1977, C.A. Viraktamath ; 6 ♂, 1 ♀, same data but collected by S. Viraktamath ( UASB) .

Remarks. Distant’s manuscript name “ delineata ” (on the specimen) is retained for this species. This species resembles I. atrovenosa and I. aurora . It can be easily distinguished by the aedeagus being more arcuate and sunk into the base of dorsal apodeme and by the caudodorsal lobe-like extention of the male pygofer.
