Description. Head ( Fig. 75A ): yellow with black and dark brown marks; eyes greyish, pubescent; face yellow, ventral brown spot; carina yellow, narrow, prominent; scape brownish yellow; pedicel basally brownish yellow, apically light yellow; flagellomere 1 brown, basal margin yellow, compressed, mango-shaped; left arista with five dorsal, right arista with four dorsal branches, one ventral branch, terminal fork; fronto-orbital plate yellow, brown spot at the base of p rc frorb s advancing posteriorly; fronto-orbital setae black, a rc frorb s anterior of pc frorb s; distance between pc frorb s and a rc frorb s = 0.02 mm, between pc frorb s and p rc frorb s = 0.07 mm, and between a rc frorb s and p rc frorb s = 0.07 mm; frons yellow, brown and black; frontal triangle light brown, large; frontal vitta brown, yellow near ptilinal suture; ocellar triangle black, prominent; postocellar setae black, not crossing; genae yellow with brown mark under the eye near vibrissa, ventral margin brown; clypeus dark brown; palps dark brown, large; labellum dark brown. Thorax ( Figs. 75B, C ): yellow and brown with darker marks; scutum light brown with several lighter brown marks, two longitudinal brown bands anteriorly parallel along the sub-dorsal vittae converging and fusing medially near the anterior dorsocentral setae, after fusing the bands diverges posteriorly resembling a triangle shape; fine gray line between the parallel brown marks; postpronotum light yellow almost white; six irregular rows of acrostichal setulae which become scarce after the anterior dorsocentral setae and absent after posterior dorsocentral setae; two pairs of posterior dorsocentral setae; transverse suture with a brown mark; scutellum dark brown with lighter margins from its base until the base of the apical scutellar setae, slightly darker at base of setae apical; scutellar setae divergent, curved inwards; pleura brown with continual light yellow band above katepisternum; proepisternum brown, ventral half light yellow; anepisternum brown apically, light brown medially and light yellow ventrally; katepisternum brown; anepimeron in shades of brown; legs tan, fore femora with slightly darker medial mark; mid and hind femur lighter basally, darker medially. Wings ( Fig. 75F ): hyaline, costal lappet large, black, apically pointy; faint darker patch present bellow costal lappet; R 4+5 and M 1 slightly divergent; halter yellow; index: C = 1.48, ac = 2.80, hb = 0.71, 4c = 1.47, 4v = 2.26, 5x = 2.31, M = 0.79, prox. x = 0.47. Length = 1.69 mm, width = 0.78 mm. Abdomen ( Figs. 75D, E ): tergites yellow with black marks; T1 yellow, laterally black; T2 dark brown, interrupted medially and sub-laterally in yellow; T3 dark brown sub-laterally interrupted in yellow, with 2 faint yellow spots sub-laterally of the brown area; T4 dark brown sub-laterally yellow, two round elongated marks sub-dorsally at the anterior margin, the yellow marks almost meet medially; T5 same as T4 but the yellow marks are pointier almost reaching the posterior margin; T6 yellow, laterally brown, medial triangle shaped brown mark pointing anteriorly; T7 yellow; sternites progressively darker posteriorly, S7 with microtrichia and with 14 setulae; intersegmental membranes light. Terminalia ( Fig. 76 ): 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; four large peg-like ovisensilla on peduncles on the posterior margin, horizontal row of six peg-like ovisensilla on the apical ventral margin, around nine tiny pegs on the ventral margin. Spermathecal capsule highly sclerotized, dome-shaped, with wrinkled rings on the basal half of the capsule; introvert almost reaching the total length of the capsule, with a depression apically. Eggs: chorion ornated dorsally with four filaments and the micropyle; the two apical filaments are about 2/3 of the length of the sub apical; the bigger filaments are 1/3 the length of the main body of the chorion. Body length: 2.10 mm.
