Material examined: Holotype male, labelled as follows: “ Brasil, Amazonas, Careiro Castanho , BR 319 km 181,Sítio São Paulo,Malaise [Trap], JA Rafael”; “ Paramycodrosophila amazonensis n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ INPA].

Diagnosis. Flies yellow with several brown marks forming a mottled pattern; head yellow and brown, pr frorb s anterior and lateral to a rc frorb s; scutum yellow with a brown area resembling three connected triangles; legs yellow; wings hyaline with a large, black, apically roundish costal lappet; abdomen with yellow and brown tergites, T5 yellow with a brown caudal band, the band reaches medially toward the anterior margin forming a large triangular shape, laterally yellow. Posterior hypandrial process present. Phallus tubular and projected ventrally, in ventral view the phallus gets wider near the phallotrema section; the phallus is micro-ornated with long scale-like structures.

Description. Holotype. Head ( Figs. 13A, C ): yellow with darker marks; eyes red, pubescent; face yellow, ventral third light brown; carina narrow, prominent; scape apically light; pedicel brown, apical half lighter; flagellomere 1 brown, compressed, mango-shaped; arista with five dorsal and one ventral branches, and terminal fork; frons yellow and brown; fronto-orbital plate yellow, slightly darker posterior to p rc frorb s; fronto-orbital setae black; 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 yellow; frontal triangle yellow, large; ocellar triangle black, prominent; postocellar setae black, crossed; genae yellow, brown at the ventral margin; palps brown, large; clypeus, labrum and labellum brown. Thorax ( Figs. 13B, C ): yellow with brown marks; scutum yellow with brown marks; two longitudinal brown triangle shaped marks reaching and fusing medially, posterior to the fusing point the brown area increases gradually in size forming another triangle shaped mark; transverse suture with a brown mark extended towards supra-alar area; fine longitudinal gray line medially in the yellow area; postpronotum light yellow; external margin of postpronotal lobe brown; six irregular rows of acrostichal setulae, absent after the posterior dorsocentral setae; anterior dorsocentral setae smaller than posterior dorsocentral setae; scutellum brown, yellow laterally near the basal margin; basal scutellar setae divergent curved inwards; apical scutellar setae missing. Pleura brown with a transversal medial light yellow band above katepisternum; proepisternum brown; anepisternum brown with large faint yellow spot medially at the posterior margin, ventral margin light yellow; anepimeron yellow with brown marks; katepisternum dark brown; meron mostly brown. Wings ( Fig. 13F ): faint darker patch present bellow costal lappet; R 4+5 and M 1 parallel; halter brown, knob yellow; index: C = 1.56, ac = 3.44, hb = 1.06, 4c = 1.62, 4v = 2.62, 5x = 2.38, M = 0.91, prox. x = 0.59. Length = 1.67 mm, width = 0.80 mm. Abdomen ( Figs. 13D, E ): T1 yellow, laterally darker; T2 brown sub-laterally interrupted in yellow, anterior half faint yellow; T3 brown sub-laterally interrupted in yellow, anterior yellow spot sub-laterally of the brown area; T4 brown, sub-laterally yellow, long yellow transversal mark at the anterior margin, the yellow mark enlarges laterally; T6 yellow; sternites light yellow; intersegmental membranes light. Terminalia ( Figs. 14 , 89F ): epandrium with approximately equal width and length, with microtrichia, with 13 (seven on the right side and six on the left side) upper and lateral setae; ventral lobe broad, glabrous, with at least four setae. Cerci connected to epandrium by the hypoproctal plate, with microtrichia, with large setae, hypoproctal plate present, ventral cecal lobes short with around four setae. Subepandrial sclerite wide, squarish, with a more sclerotinized band, connected to the surstylus. Surstylus with four prensisetae arranged in a line, about five longer inner setae arranged in a line and two lonely inner setae; two outer setae. Hypandrium squarish anteriorly with curved lateral margins, wider than long, smaller than epandrium, with a large and broad posterior hypandrial process. Pregonites small, fused to the hypandrium laterally, not fused medially.Postgonites thick and straight in lateral view, containing at least three setulae near the fusion with pregonite. Phallotrema is wide. Phallapodeme is slightly smaller than phallus and slightly curved ventrally. Body length: 2.08mm.

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