Igerna wilsoni sp. nov.

Figs 381–390.

Color. Head with pair of black spots one on either side of median line, clypellus, lora, antennal bases, clypeus, chocolate brown, median stripe on frons extending to clypeus and spots enclosing lower part of ocelli, chocolate brown. Pronotum with anterior margin, two connected lateral spots and median stripe extending from it, chocolate brown. Anterior half of scutellum black, median rounded extension of same on posterior half brown. Forewing cells brown.

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

Male genitalia. Pygofer simple, caudal margin rather truncate. Styles typical of Igerna . Connective sclerotized and pigmented, longer than wide, lateral margins excavated. Aedeagus complex, stout basally, with ventral platelike apodeme having distal median acuminate process; aedeagal shaft with pair of basal processes directed caudally, shaft slender, with pair of lateral subapical teeth, at base of ventral apodeme and base of aedeagus with spines; gonopore apical. Anal collar simple.

Measurement. Male 4.10 mm long and 1.30 mm wide across eyes.

Material examined. INDIA: HOLOTYPE ♂, West Bengal: Gopaldhara BW, Darjeeling, 4720 ft (1431m), 24.iii.1918, H. Stevens ( BMNH).

Remarks. Igerna wilsoni resembles species of Japanagallia but lacks the cross veins between the claval veins. It shares a ventral process of the aedeagus with some undescribed species of Igerna from the Afrotropical region and I. quinlani . None of the other Oriental Igerna possesses a spine-like structure on the aedeagus. The species is named after Dr M. R. Wilson, in recognition of his contributions to Auchenorrhyncha systematics.
