( Figs. 11 , 12 , 81E , 89E )

Material examined: Holotype male, labelled as follows: “ Brasil, Roraima, Caracaraí, PARNA [=National Park] Viruá , 1°27’16”N; 60°59’3”W, 1-15/v/2016, Malaise [Trap] Pequena, JA Rafael; R Boldrini - Rede BIA [= Thematic network “Biodiversity of Insects in the Amazon ”]”; “ Paramycodrosophila roraimensis n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ INPA] . Holotype condition: Aristae and several setae missing.

Diagnosis. Flies yellow with several brown areas forming a mottled pattern; yellow scutum with a semicircular brown shape adjacent to the posterior margin; pleura yellow with transversal brown marks; legs yellow with fore coxae yellow with posterior half darker; wings hyaline with large, apically pointy, black costal lappet; abdomen with yellow, black and brown tergites. T5 yellow laterally brown, medial triangle shaped dark brown spot pointing anteriorly, sub-lateral small dark brown spot at the posterior margin. Phallus tubular and projected ventrally, in ventral view the phallus gets gradually wider from the base to the apex; the apex of the phallus has one medial pointy projection and two wide, round lateral projections; anterior to the phallotrema there are two pointy projection pointing ventrally.

Description. Holotype. Head ( Fig. 11A ): yellow with black and dark brown marks; eyes greyish, pubescent; face yellow; carina yellow,narrow, prominent;scape brownish yellow; pedicel basally brownish yellow, apically light yellow; flagellomere 1 brown, basal margin yellow, apically darker, compressed, mango-shaped; aristae missing; frons yellow with brown marks; fronto-orbital plate yellow, brown spot at the base of p rc frorb s advancing posteriorly; fronto-orbital setae black, a rc frorb s lateral and slightly posterior 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 = 0.06 mm; frontal vitta brown posterior of a rc frorb s; frontal triangle yellow, large; ocellar triangle black, prominent; postocellar setae black, crossing; genae yellow with brown mark under the eye near vibrissa, ventral margin dark brown progressively lighter posteriorly; clypeus light brown; palps dark brown, large; labrum light yellow with brown marks; labellum dark brown. Thorax ( Figs. 11B, C ): yellow with brown marks; scutum light brown with several lighter brown marks, two longitudinal brown bands anteriorly parallel sub-medially converging sharply and fusing medially at the center of scutum; posterior to the fusion, the bands are replaced by brown spots at the base of mid acrostichal rows; brown mark at the posterior margin of scutum reaching the height of posterior dorsocentral forming a semicircle shape; fine gray line between the parallel brown marks; postpronotum light yellow; six irregular rows of acrostichal setulae which become scarcer after the anterior dorsocentral; dorsocentral setae missing; transverse suture with a brown mark extending toward the supra alar region; scutellum brown with lighter margins from its base until the base of the apical scutellar setae, slightly darker at base of setae; scutellar setae missing; pleura light yellow with brown marks; proepisternum brown, ventral half lighter; anepisternum yellow, brown apically; anepimeron yellow with brown marks; katepisternum yellow, brown band near the dorsal and posterior margin; meron light yellow. Wings ( Fig. 11F ): faint darker patch present bellow costal lappet; R 4+5 and M 1 parallel; halter yellow; index: C = 1.53, ac = 1.53, hb = 0.73, 4c = 1.50, 4v = 2.30, 5x = 3.00, M = 0.80, prox. x = 0.53. Length = 1.37 mm, width = 0.61 mm. Abdomen ( Figs.11D, E ): tergites yellow with dark brown to black marks; T1 yellow, laterally black; T2 dark brown, sub-laterally in yellow, medial faint yellow mark; T3 dark brown to black sub-laterally interrupted in yellow, with two faint yellow spots at the anterior margin sub-laterally of the brown area; T4 dark brown sub-laterally yellow, elongated yellow mark at the anterior margin, the yellow mark enlarges and becomes round laterally; T6 yellow; sternites yellow; intersegmental membranes light. Terminalia ( Figs. 12 , 89E ): epandrium slightly longer than it is wide, with microtrichia, with 10 upper setae; ventral lobe short, glabrous, with one sub-apical and two long apical setae. Cerci not fused to epandrium, with microtrichia, with large setae, hypoproctal plate present, ventral cecal lobes large with many long setae. Subepandrial sclerite wide, squarish. Surstylus connected to the epandrium, with prensisetae arranged in a line, about five longer inner setae and shorter outer setae. Hypandrium roundish, longer than wide, smaller than epandrium. Pregonites large and corrugated, fused to the hypandrium laterally, not fused medially. Postgonites thick, short and straight in lateral view, containing setulae near the fusion with pregonite. Phallotrema is wide. Phallapodeme is longer than phallus and slightly curved ventrally. Body length: 1.53 mm.

Etymology. Named in reference to the state of Roraima, where the holotype was collected.
