VIRAKTAMATH, C. A. & YESHWANTH, H. M., 2024, Arboreal eurymeline leafhoppers (Hemiptera: Cicadellidae: Eurymelinae) of the Indian subcontinent with description of new genera and eight new species, Zootaxa 5462 (1), pp. 1-125 : 70

Genus Nilgiriscopus Viraktamath

Nilgiriscopus Viraktamath 2007: 28 . Type species: Nilgiriscopus transversus Viraktamath , by original designation.

Diagnosis. Lemon yellow with black spots on pronotum and exposed mesonotum. Crown and face dorsad of ocelli and pronotum transversely striate. Ocelli high on face, closer to adjacent eye than to median line. Clypellus parallel sided. Forewing with two closed subapical cells. Meta femur with 2+1 distal macrosetae. Male pyoger with well-developed anterior dorsal apodemes without dorsal basal fracture, without ventral process. Style with ventral margin distinctly bilobed at midlength, ventral margin of apophysis serrate. Aedeagus simple, without long processes, with well-developed preatrium, dorsal apodeme short, gonopore apical.

Remarks. Viraktamath (2007) adequately described the genus. From the other two genera of idoceerines with transversely striate pronotum occurring in the Indian subcontinent, namely Jogocerus and Tasnimocerus , this genus can be readily differentiated by the clypellus being parallel sided and the male pygofer lacking anal collar process and pygofer processes. In addition, from Jogocerus it differs in having the male pgyfer without a basal fracture and from Tasnimocerus in having only two subapical cells in the forewing and monocolored forewing veins instead of having veins marked alternatively with black and white as in Tasnimocerus .
