( Figs. 43 , 44 , 83C , 90F )

Material examined: Holotype male, labelled as follows:“ Brasil, Acre, Senador Guionard, RE [=Experimental Reserve] Catuaba , 10°04’28”S; 67°37’00”W 18-30/iv/2017, Malaise, EF Morato; JA Rafael, Rede BIA [= Thematic network “Biodiversity of Insects in the Amazon ”]”; “ Paramycodrosophila acreensis n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ INPA] . Holotype condition: Wrinkled, left fore tarsus missing.

Diagnosis. Flies yellow with several brown areas forming a mottled pattern; head with pale face and brown frons; ocellar triangle black and exceptionally prominent; scutum mostly brown, yellow areas fuse resembling an uppercase “M”; 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 large, apically roundish, black costal lappet; abdomen with tergites dark brown and yellow. Posterior hypandrial process present. Phallus tubular, projected ventrally, 2x as wide in the phallotrema section, the phallotrema section is ornated with tiny lumps dorsally, squarish apically, with a broad triangular lateral projection; in lateral view phallotrema section is narrow.

Description. Holotype. Head ( Fig.43A ): pale with brown marks; eyes dark red,pubescent;face pale brown with a prominent small narrow carina; scape covered; pedicel brown, apically light yellow; flagellomere 1 light brown anterior margin light, compressed, mango-shaped; arista with at least five dorsal and one ventral branches, and terminal fork, some dorsal branches missing;frons light yellow with brown marks; fronto-orbital plate same color as anterior of frontal vitta, dark brown at the base of and p rc frorb s and posteriorly; fronto-orbital setae black; pc frorb s lateral to 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 light brown, pale on the anterior first third; frontal triangle brown, darker near ocellar triangle, large; postocellar setae black, not crossing; genae light yellow, ventral margin black; palps brown,large, slightly curved upwards; labrum brown with lighter marks; labellum brown. Thorax ( Figs. 43B, C ): brown with yellow with greyish marks;scutum brown with several marks; v1 greyish,progressively larger anterior to the middle point of scutum; v2 and v3 brown; v4 yellow fine; v5 brown; v6 greyish with a large dark brown mark in the supra alar region; v2 converges and fuse medially; v1 and v4 converges and fuse anteriorly”;four regular rows of acrostichal setulae,acrostichal setulae absent posterior of the height of the anterior dorsocentral setae; postpronotum light yellow; dorsocentral setae missing; scutellum brown, apical margin yellow;scutellar setae missing; pleura brown with light yellow band above katepisternum; proepisternum brown; anepisternum brown, lighter near the ventral margin, yellow faint band medially; anepimeron brown with ventral margin lighter; katepisternum dark brown apically, progressively lighter ventrally; meron mostly brown; legs yellow with brown marks; coxae yellow with marks. Wings ( Fig. 43F ): faint darker patch present bellow costal lappet; R 4+5 and M 1 parallel; halter yellow; index: C = 1.72, ac = 2.85, hb = 0.82, 4c = 1.46, 4v = 2.36, 5x = 2.21, M = 0.79, prox. x = 0.54. Length = 1.88 mm, width = 0.85 mm. Abdomen ( Figs. 43D, E ): T1 dark brown; T2 dark brown sub-laterally interrupted in yellow;T3dark brown sub-laterally interrupted in yellow; T4 dark brown sub-laterally interrupted in yellow, round yellow mark at the anterior margin sub-laterally of the central brown area;T5dark brown sub-laterally interrupted in yellow,large round yellow mark at the anterior margin sub-medially of brown area; T6 yellow, light brown caudal band enlarged medially, laterally the band reaches the anterior margin;sternites tan;intersegmental membranes light. Terminalia ( Figs. 44 , 90F ): epandrium is approximately equal width and length, with microtrichia, with 14 upper setae; ventral lobe large, broad, glabrous, with six long apical setae, and one basal seta. Cerci projected posteriorly, not fused to the epandrium, glabrous, with very long setae. Subepandrial sclerite sclerotinized.Surstylus with around nine prensisetae, four inner and three outer setae.Hypandrium longer than wide, squarish; larger 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 broader in lateral view. Phallapodeme slim,smaller than phallus,straight. Body length: 2.03 mm.

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