INTRODUCTION mandible; face about as long as wide, indistinctly punctuate
with hairs, with a faint median longitudinal node; frons
The genus Neoclarkinella was erected by Rema and concave, smooth and shiny; occiput smooth; temple and
Narendran (1996) to accommodate N. nilamburensis as its
type species. It can be easily distinguished from its closely
related genus Clarkinella in having large and triangular
scutellarlunule,forewingwithoutareolet,transversecarinae
of propodeum not forming a fork on either side of spiracle
and hypopygium striate along median line. The genus is
knownonlyfromitstypespecies. Inthepresentwork, anew
speciesisdescribed from India.
