Thorax ( Figs. 69B, C ): yellow with brown marks;scutum yellow with two sub-medial brown marks anteriorly parallel reaching the anterior dorsocentral setae, longitudinal yellow band external to the longitudinal brown marks,fine gray line medially,dark brown posteriorly, cross-shaped mark in the center of scutum partially formed by partially fused spots; supra-alar region brown; base of the notopleural and dorsocentral setae with brown spots; postpronotum light yellow; external margin of postpronotum brown;four irregular rows of acrostichal setulae which become scarce posterior to the anterior dorsocentral setae and absent posterior to posterior dorsocentral setae, anterior dorsocentral setae smaller than posterior dorsocentral setae; scutellum dark brown, gradually lighter towards lateral and posterior margins, dark spots at the base of scutellar setae; basal scutellar setae convergent, almost straight, slightly curved inwards;apical scutellar setae convergent,slightly curved inwards, crossing;pleura light yellow with brown marks; proepisternum, anepimeron and anepisternum light yellow with dorsal transversal bands forming a continuous dark brown band; katepisternum light yellow, dorsal half dark brown; meron yellow; legs tan, mid and hind femora with brown marks medially. Wings ( Fig. 69F ): hyaline with a large black apically roundish costal lappet; faint darker patch present bellow costal lappet; R 4+5 and M 1 parallel; halter light yellow; index: C = 1.47, ac = 3.55, hb = 0.87, 4c = 1.73, 4v = 2.73, 5x = 2.47, M = 0.93, prox. x = 0.64. Length = 1.63 mm, width = 0.80 mm. Abdomen ( Figs.69D, E ): tergites yellow with black marks; T1 yellow, laterally black; T2 black, interrupted medially and sub-laterally in yellow; T3 black with two yellow spots, interrupted medially and sub-laterally in yellow,the yellow spots are anterior and sub-lateral to the large black areas; T4 yellow, caudal black band interrupted sub-laterally in yellow, the band enlarges medially similar to a triangle and reaches the anterior margin laterally; T5 is like T4; T6 yellow with a black caudal medial triangular spot and laterally black; T7 yellow; sternites light yellow, S7 with microtrichia and with eight setulae; intersegmental membranes light. Terminalia ( Fig.70 ): T8 with microtrichia in the dorsal region; epiproct and hypoproct with microtrichia,with many long and some smaller setae; oviscapt valves asymmetrical, left valve shorter than right valve; oviscapt vale sclerotinized, long, squarish at the tip in lateral view; three large peg-like ovisensilla on the posterior margin,horizontal row of five peg-like ovisensilla on the apical ventral margin, around 13 tiny pegs on the ventral margin. Spermathecal capsule sclerotized, dome-shaped, roundish; introvert reaching the total length of the capsule. Eggs: chorion ornated, with four filaments and the micropyle; the two apical filaments are about 2/3 of the length of the sub apical. Body length: 1.87 mm.
