Genus Lankacerus Viraktamath

Lankacerus Viraktamath 2007: 25–26 . Type species: Lankcerus rotundus Viraktamath , by original designation.

Diagnosis. The genus to be recognized among the genera of Eurymelinae from the Indian subcontinent by the absence of cross veins that close the subapical cells and by having a single vein in the forewing clavus. Genus Neoscopus also does not have cross veins closing the subapical cells but has two claval veins. Crown and face dorsad of ocelli shagreen. Segment X large with lobe-like lateral surface. Male pygofer without anterior marginal apodemes, without basal fracture, without ventral process. Style apophysis with basal tooth on ventral surface. Aedeagus simple with small dorsal apodeme and well-developed preatrium. Gonopore subapical.

Remarks. Viraktamath (2007) adequately described the genus and distinguished it from Philippocerus Maldonado-Capriles by the shape of the clypellus. In Lankacerus the clypellus is broader apically whereas it is parallel sided in Philippocerus . Male pygofer in Phlipposcopus has anterior marginal apodemes and posterodorsal angle spine-like that are absent in Lankacerus .
