Forewing either uniformly infuscate behind venation or with infuscated bands of various shapes and bearing darker setae; stigmal
vein either with a thin or swollen stigma; postmarginal vein absent; submarginal vein with 1 seta; marginal vein with 3-4 setae; usually 1 seta present on stigmal
vein and 1 at junction of parastigma and submarginal vein; disc sparsely or densely setose, or setae arranged in groups and/or tufts.
Posterior spiracles (Figs 24, 25): On extremely short stigmatophores, each with three radiating, elliptical, long and narrow stigmal
openings (stigo) in a shamrock-shaped cuticular depression, surface between them smooth, positioned on a sub-triangular spiracular plate, ecdysial scar large, rounded and conspicuous; with four peristigmal tufts (Figs 24, 25, pstgt), inserted between stigmal
openings on spiracular plate, broad and blade-like basally with 5-7 long, narrow undivided filaments.
Marginal vein 1/3 of postmarginal vein; stigmal
vein slightly curved and 1.1 times longer than postmarginal vein.
Forewing hyaline, without dark transverse bands or spots; distal part of stigmal
vein much shorter than proximal part (3:11).
Forewing hyaline, without dark transverse bands; stigmal
vein regularly curved.
The characters distinguishing the new species are the following: frontal line incomplete; scutellum granulated; forewing hyaline, without dark transverse bands; distal part of stigmal
vein longer than proximal part; dorsal process of para-mere long and sharp, regularly curved, slightly scytheshaped, located in distal region of param-ere.
The closely-placed scutellar placoid sensilla, and the shape of the stigmal
vein, strongly suggest it is a member of the Encarsia strenua (Silvestri) group, all species of which are parasitoids of Aleyrodidae.
