Material examined: Holotype male, labelled as follows:“BRA [= Brazil] – MG [ State of Minas Gerais] – Bocaina de Minas (22°19’46.3”S, 44°32’31.5”W) Data: 25.xii.2018 - 09.i.2019 Col.: Telles MHF OBS.: Armadilha Malaise”; “ Paramycodrosophila mineira n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ MZUSP] . Holotype Condition: Wrinkled, and with faded coloration.

Diagnosis. Flies yellow with brown and black marks forming a mottled pattern; head yellow and brown; scutum yellow with the longitudinal brown band medially; scutellum mostly yellow with apical scutellar setae highly convergent; pleura yellow with longitudinal brown bands; wings hyaline with darkish, apically pointy costal lappet; abdomen with yellow and black tergites. Phallus tubular, broad and projected ventrally; in ventral view the phallus is diamond-shaped; the apically and sub apically the phallus is micro-ornated with small lumps dorsally; in lateral view the lateral margins of phallotrema seem concave.

Description. Holotype. Head ( Figs. 19A, C ): yellow with brown marks; eyes greyish, pubescent; face brown; carina light yellow, narrow, prominent; parafacialia yellow; scape covered; pedicel yellow, apically light brown; flagellomere 1 brown, yellow apically, compressed, mango-shaped; arista with five dorsal and one ventral branches, terminal fork; frons brown and yellow; fronto-orbital plate yellow; fronto-orbital setae black, right a rc frorb s lateral and slightly anterior to pc frorb s, left a rc frorb s lateral and slightly posterior to pc frorb s; distance between pc frorb s and a rc frorb s = 0.03 mm, between pc frorb s and p rc frorb s = 0.08 mm, and between a rc frorb s and p rc frorb s = 0.07 mm; frontal vitta brown, yellow near ptilinal suture; frontal triangle brown, large; ocellar triangle black, prominent; postocellar setae black, meeting at the tip; genae light yellow with light brown mark under the eye near vibrissa, brown at the ventral margin; clypeus, palps, labrum and labellum brown, palps large. Thorax ( Figs. 19B, C ): yellow with brown marks; scutum yellow, brown between dorsocentral rows, transversal suture brown, brown band form near the tip of transversal suture advancing posteriorly, postpronotum light yellow, external margin of postpronotum brown; six regular rows of acrostichal setulae which are absent after the posterior dorsocentral setae; anterior dorsocentral setae smaller than posterior dorsocentral setae; scutellum yellow, brownish medially near de basal margin; apical scutellar setae crossing; pleura light yellow with brown marks; proepisternum and anepisternum yellow, dorsally brown forming a continual band; anepimeron with transversal brown band medially; katepisternum dorsal half brown; meron brownish. Wings ( Fig. 19F ): faint darker patch present bellow costal lappet; R 4+5 and M 1 parallel; R 2+3 slightly curved to costal at its tip, halter light yellow, basally darker; index: C = 1.56, ac = 3.37, hb = 1.00, 4c = 1.64, 4v = 2.74, 5x = 3.07, M = 1.10, prox. x = 0.54. Length = 1.94 mm, width = 0.90 mm. Abdomen ( Figs. 19D, E ): T1 yellow, laterally black; T2 black, interrupted sub-laterally in yellow, anterior faint yellow mark medially; T3 black, interrupted sub-laterally in yellow, faint yellow spot sub-laterally of the black area; T4 black interrupted sub-laterally in yellow, large round yellow shape sub-medially at the anterior margin; T5 yellow with a caudal black band, the band reaches toward the anterior margin reaching it, laterally yellow; T6 yellow; sternites brownish; intersegmental membranes light. Terminalia ( Figs.20 , 89H ): epandrium is approximately equal width and length, with microtrichia, with eight upper and two lateral setae; ventral lobe short, narrow, glabrous, with two long apical setae and one shorter basal seta. Cerci not fused to the epandrium, with microtrichia, with large setae, hypoproctal plate present, ventral cecal lobes broad with setae. Surstylus broad with a row prensisetae dorsally, about five longer inner setae arranged in a line and three small outer setae. Hypandrium squarish, longer than wide, smaller than epandrium. Pregonites corrugated, large, fused to the hypandrium, not fused medially, with a seta near the fusion to the postgonite. Postgonites short, thick and wider near pregonite, containing at least three setulae near the fusion with pregonite. Phallotrema is large. Phallapodeme is smaller than phallus and slightly curved ventrally. Body length: 1.69mm.

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