Thorax ( Figs. 73B,C ): yellow and brown; scutum yellow with two anterior sub medial parallel bands sharply converging medialy at the height of the transversal suture, the bands are replaced by faint spots posterior to the fusion at the base of mid acrostichal rows; postpronotum light yellow almost white; six irregular rows of acrostichal setulae which become scarce after the anterior dorsocentral setae;anterior dorsocentral setae smaller than posterior;transversal suture with a brown mark. Scutellum yellow; basal scutellar setae converging apical scutellar setae convergent; scutellar setae curved inwards; pleura brown with continual light yellow band above katepisternum; proepisternum brown, ventral half light yellow;anepisternum in shades of brown, yellow near the ventral margin; anepimeron in shades of brown, yellow near the ventral margin; katepisternum yellow with dorsal brown band; meron yellow. Legs yellow, fore and hind femora with slightly darker ring near the base. Wings ( Fig.73F ): hyaline with a black apically pointy large costal lappet; faint darker patch present bellow costal lappet; R 4+5 and M 1 slightly parallel; halter yellow; index: C = 1.38, ac = 3.55, hb = 1.00, 4c = 1.86, 4v = 2.88, 5x = 2.69,M = 1.02,prox.x= 0.55.Length = 2.19mm,width = 0.98mm. Abdomen ( Figs.73D, E ): tergites yellow with black marks; T1 yellow,laterally black; T2 dark brown, interrupted sub-laterally in yellow; T3 dark brown sub-laterally interrupted in yellow, with two yellow spots sub-laterally of the brown area; T4 dark brown sub-laterally yellow, two round elongated marks sub-dorsally at the anterior margin; T5 yellow with five posterior marks, two laterally,two sub-laterally,one large triangle shaped medially; T6 yellow with a spot medially; T7 yellow; sternites progressively darker posteriorly, S8 with microtrichia and with 10 setulae.; intersegmental membranes light. Terminalia ( Fig.74 ): T8 with microtrichia in the dorsal region; epiproct and hypoproct with microtrichia, with many long and some smaller setae; oviscapt vale sclerotinized,long, squarish at the tip in lateral view;4 large peg-like ovisensilla on the posterior margin, horizontal row of 9 peg-like ovisensilla on the apical ventral margin, around six tiny pegs on the ventral margin; Spermathecal capsule highly sclerotized, dome-shaped, longer than it is wide, with wrinkled rings on the basal half of the capsule; introvert 1/2 the total length of the capsule, with a small depression apically. Body length: 2.53mm.
