Igerna wilsoni Viraktamath

Figs 6A–K

Diagnosis. Externally resembling J. turriformis Zhang & Dai (2018) but differs in having the aedeagus in proximal region more or less rectangular and shaft ventral process much longer than shaft in lateral view, aedeagal shaft with one pair of long, basilateral processes and one pair of subapical teeth on ventral surface and shaft apex slightly flared.

Material examined. INDIA: Arunachal Pradesh: 1♂, Monigong, 13.vii.2022, at light, Ajaykumara K. M .; 1♂, Hunli, 30.viii.2022, Ajaykumara K. M. ( UASB) .

Remarks. Viraktamath (2011) adequately described and illustrated this species based on the holotype male collected from Gopaldhara, Darjeeling (West Bengal). In the holotype there are no cross veins between the claval veins and hence the species was placed in the genus Igerna . However, the specimens collected from Hunli and Monigong have a claval cross vein either on one or both forewings ( Fig.6A ). Igerna and Japanagallia are closely related and often difficult to segregate and Viraktamath (2011) separated them based on the presence or absence of the claval cross veins in the forewing. Therefore, more critical examination of the species of Igerna and Japanagallia described from the Oriental region is necessary using both morphological and molecular characters to segregate them with higher confidence.
