Material examined: Holotype male, labelled as follows: “ Brasil, Bujari , FES [=State Forest] Antimary, 9°20’01”S; 60°19’17”W, 18-31/ viii/2017, Malaise [Trap] Grande, EF Morato, JA Rafael, cols - Rede BIA [= Thematic network “Biodiversity of Insects in the Amazon ”]”; “ Paramycodrosophila pallidifacies n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ INPA] . Holotype condition:Several setae missing.

Diagnosis. Flies dark brown and yellow forming a mottled pattern; Head from pale brown to dark brown, antennae mostly pale; scutum mostly dark brown with longitudinal lighter marks; pleura mostly brown with a longitudinal light yellow band above katepisternum; legs with femora and tibiae yellow with two dark brown rings each, femora with one basal and one sub-apical and tibiae with one sub-basal and one sub-apical; wings infuscated with an apically roundish, large, black costal lappet; abdomen with tergites yellow, brown and black.Posterior hypandrial process present. Phallus tubular, projected ventrally, 2x as wide in the phallotrema section, the phallotrema section is ornated with tiny lumps; in ventral view phallotrema section is squarish, in lateral view the phallotrema section is narrow.

Description. Holotype. Head ( Fig. 41A ): pale with black and brown marks; eyes red, pubescent; face pale brown with a small carina, dark marks near carina; scape covered; pedicel light yellow, apically lighter; flagellomere 1 light yellow, transversal posterior brown mark, compressed, mango-shaped; arista with seven dorsal and one ventral branches, and terminal fork; frons light yellow and brown; fronto-orbital plate greyish light brown, dark brown to black at the base of and p rc frorb s and posteriorly; fronto-orbital setae black; pc frorb s lateral of a rc 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 pale brown; frontal triangle brown, large; ocellar triangle black, very prominent; postocellar setae missing; genae brown, darker at the ventral half; palps dark brown, large, long, curved upwards; labrum brown with lighter marks; labellum brown. Thorax ( Figs. 41B, C ): dark brown and yellow; v1 brown; v2 light brown, fused anteriorly; v3 brown, fused with v 6 in the posterior 4/5 of the scutum; v4 greyish light brown; v5 brown; v6 yellow with a large dark brown mark in the supra alar region; transverse suture brown; six rows of acrostichal setulae, setulae missing or absent on the posterior half; postpronotum light yellow, anteriorly darker; dorsocentral setae missing; scutellum dark brown, lighter between the apical and basal scutellar setae and between apical setae; scutellar setae missing; pleura yellow with dark brown marks, one transversal continuous light yellow band above the dorsal margin of katepisternum; proepisternum dark brown, ventral half lighter, light medial transversal band; anepisternum yellow with dark brown band at dorsal margins, two dark brown spots near the dark brown band partially fused; anepimeron yellow with brown transversal brown band; katepisternum dark brown; meron mostly light brown; legs yellow with dark brown marks; coxae yellow with brown marks. Wings ( Fig. 41F ): faint darker patch present bellow costal lappet; R 4+5 and M 1 very slightly divergent; R 2+3 slightly curved to costal at its tip; halter yellow; index: C = 1.46, ac = 2.92, hb = 0.91, 4c = 1.59, 4v = 2.30, 5x = 1.88, M = 0.73, prox. x = 0.50. Length = 2.05 mm, width = 0.94 mm. Abdomen ( Figs. 43D, E ): T1 dark brown; T2 dark brown almost black sub-laterally interrupted in yellow, medially faint yellow near anterior margin, faint yellow spot sub-laterally of the brown area at the anterior margin; T3 black sub-laterally interrupted in yellow, faint yellow spot sub-laterally of the brown area at the anterior margin; T4 black sub-laterally interrupted in yellow, yellow round mark sub-laterally of the brown area at the anterior margin; T5 black, laterally yellow, yellow elongated round mark sub-medially at the anterior margin; T6 yellow, caudal brown band advancing medially and laterally to the anterior margin; sternites brown; intersegmental membranes not showing. Terminalia ( Figs. 42 , 90E ): epandrium is approximately equal width and length, with microtrichia, with 16 upper setae; ventral lobe large, broad, glabrous, with around three long and two short apical setae, and one basal seta. Cerci not fused to the epandrium, glabrous, with very long setae. Subepandrial sclerite squarish, membranous. Surstylus with many prensisetae, inner and outer setae. Hypandrium almost as wide as it is long, squarish; shorter than epandrium, with a broad and short posterior hypandrial process. Pregonites fused to the hypandrium, not fused medially, with a seta near the fusion with the postgonite. Postgonites slim. Phallotrema is round. Phallapodeme slim, smaller than phallus, curved ventrally. Body length: 2.08mm.

Etymology. Named in reference to the pallid aspect of its face.
