( Figs. 79 , 80 , 88C )

Material examined: female labelled as follows:“ Brasil, Acre, Senador Guionard, FE [=Experimental Farm] Catuaba , 10°04’28”S; 67°37’00”W 18-30/iv/2017, Malaise [Trap], EF Morato; JA Rafael, Rede BIA [= Thematic network “Biodiversity of Insects in the Amazon ”]”, “ AM12 ” [ INPA]. Specimen condition: Left arista partially destroyed, fore legs missing except for coxae, dorsocentral setae missing, scutellar setae missing .

Description. Head ( Figs. 79A, C ): yellow with black and dark brown marks; eyes red, pubescent; face with a large, prominent carina, brownish; scape light brown; pedicel brown, light yellow at apical margin; flagellomere 1 light yellow with a brown ring medially, apically brownish, compressed, mango-shaped; right arista with eight dorsal branches, two ventral branches and terminal fork; frons yellow and brown; fronto-orbital plate yellow, dark brown spots at the base of front-orbital setae; a rc frorb s slightly anterior and close to 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; frontal vitta brown, yellow near ptilinal suture; frontal triangle brownish, large; ocellar triangle dark brown, prominent; genae yellow, anterior half black; palps black; labellum brown. Thorax ( Figs. 79B, C ): yellow with brown marks; scutum yellow with one squarish shaped brown mark between dorsocentral rows and between the height of transversal suture and the height of the middle point of dorsocentral setae, two sub-medial longitudinal brown bands on the second fifth of scutum, the brown bands fuse with the square shaped marks on its vertex, transversal brown band on the presutural region fused with the longitudinal brown marks, supra-alar region mostly brown, the brown area of the supra alar region is fused with the square shaped mark at the base of the anterior dorsocentral setae; posterior to the square shaped mark, the scutum in light brown between the dorsocentral rows; base of dorsocentral setae with brown spots; scutellum light brown with yellow lateral and posterior margins; black spots at the base of scutellar setae; pleura with one longitudinal fine brown dorsal band, one medial broad longitudinal light band, and one longitudinal broad brown ventral band, anepimeron brownish, laterotergite brown ventrally. Legs with fore coxa brown; mid and hind legs yellow with dark broad ring on the femora medially and a darker ring on tibiae near its base. Wings ( Fig. 79F ): hyaline with a very large and broad black apically round costal lappet; faint darker patch present bellow costal lappet; R 4+5 and M 1 Parallel; halter light yellow with brownish mark; index: C = 1.15, ac = 3.40, hb = 0.98, 4c = 1.55, 4v = 1.93, 5x = 1.41, M = 0.55, prox. x = 0.45. Length = 1.83 mm, width = 0.78 mm. Abdomen ( Figs.79D, E ): T1 brownish yellow, laterally brown, medially darker; T2 and T3 brown, sub-laterally interrupted in yellow, yellow spot laterally of the large brown area; T4 brown, yellow longitudinal mark sub-laterally from the anterior margin almost reaching the posterior margin, two large sub-medial yellow areas resembling two semicircles adjacent to the anterior margin; T5 same as T4 but the yellow semicircle areas are larger thus assuming a more squarish form; T6 same as T5 but the yellow area reaches the posterior margin laterally and fuses with the sublateral yellow area; T7 yellow, laterally brown; sternites with a mottled aspect; S7 with microtrichia and 10 setulae; intersegmental membranes light. Terminalia ( Fig.80 ): T8 bare; oviscapt vale sclerotinized, with two round lobes apically in lateral view; two peg-like ovisensilla on the most dorsal lobe, two tiny ovisensilla between the two peg-like ovisensilla; seven peg-like ovisensilla on the most ventral lobe, the one outer ovisensillum in the height of the third peg-like ovisensillum; around seven tiny pegs on the ventral margin of oviscapt valve; epiproct and hypoproct with microtrichia, with many long, epiproct with smaller setae; spermathecal capsule highly sclerotized, dome-shaped, roundish; introvert 2/3 of the total length of the capsule, with a small depression apically. Eggs: chorion ornated dorsally, with four filaments and the micropyle; the 2 apical filaments are almost the length of the sub-apical; the bigger filaments are 1/4 the length of the main body of the chorion. Body length: 2.08 mm.
