Legs including coxae brownish yellow. Scutellum flat. Antennal 
funicular segments 5-6 not transverse. Forewing not less than

femora, fore and hind tibiae more or less darkened. Scutellum 
convex. Antennal funicular segments 5-6 transverse, forewing 
length: width ratio variable. 3 
3. Apical 2-3 funicular segments white or yellow. Minimum width of 
vertex about 0.20 times maximum width of head (extreme 3:14).

dark setae on apex . 6
