Thorax ( Figs. 59B, C ): yellow with dark brown marks; scutum with two dark sub-medial bands converging and fusing medially at the height of transversal suture forming a large cross shape; transversal suture with dark brown marks which advances towards supra alar region; dark brown spots at the base of dorsocentral setae; postpronotum light yellow; external margin of postpronotum brown; medial yellow area slightly darker than other yellow areas of scutum; fine longitudinal greyish band medially; faint darker spots at the base of setulae posterior to the fusing of brown bands; six irregular rows of acrostichal setulae; acrostichal setulae absent posterior to the posterior dorsocentral setae; anterior dorsocentral setae smaller than posterior dorsocentral setae; scutellum dark brown, yellow spot apically; yellow laterally at the anterior margin; scutellar setae convergent; pleura brown with a longitudinal yellow band above katepisternum. Legs tan, femora slightly lighter. Wings ( Fig.59F ): slightly infuscated with a large black apically roundish costal lappet; faint darker patch present bellow costal lappet; R 4+5 and M 1 parallel; R 2+3 slightly curved to costal at its tip; halter light yellow; index: C = 1.93, ac = 2.96, hb = 0.64, 4c = 1.22, 4v = 2.09, 5x = 2.15, M = 0.74, prox. x = 0.47.

Abdomen ( Figs.59D, E ): T1 yellow; T2 dark brown sub-laterally interrupted in yellow, anterior faint yellow spot sub-laterally of the large dark brown area, yellow medially near anterior margin; T3 dark brown sub-laterally interrupted in yellow, anterior yellow spot sub-laterally of the large brown area; T4 yellow, dark brown caudal band, the band advances towards the anterior margin medially and laterally, laterally yellow; T5 yellow with a dark brown triangle shaped mark medially, caudal dark brown marks sub-laterally; T6 yellow with dark brown triangle shaped mark medially; T7 yellow; sternites yellow, S7 with microtrichia and with eight setulae (five on the left side, three on the right side); intersegmental membranes light. Terminalia ( Fig. 60 ): T8 with microtrichia in the dorsal region, and four setae on the ventral region; epiproct and hypoproct with microtrichia, with many long and some smaller setae; oviscapt vale sclerotinized, long, squarish in lateral view; horizontal row of many (21-22) peg-like ovisensilla ventral margin, the ovisensilla are densely grouped on the posterior region. Spermathecal capsule sclerotized,dome-shaped,roundish,with a sub-basal ring groove; introvert 3/5 the total length of the capsule. Body length: 2.34mm.
