Material examined: Holotype male, labeled as follows: “BRA [= Brazil] – RJ [= State of Rio de Janeiro] – PARNA [= National Park ] de Itatiaia (22°25’54.39”S, 44°37’18.24”W) Data: 18.i.2021 - 29.i.2021 Col.: Telles MHF OBS.: Armadilha [=Trap] Malaise”; “ Paramycodrosophila itatiaiensis n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ MZUSP].

Diagnosis. Flies yellow with brown marks forming a mottled pattern; legs tan with darker rings from near the base to the middle of the femora; scutum yellow with many brown markings, pleura with katepisternum entirely dark; wings hyaline with a large apically pointy black lappet; abdomen with tergites yellow with black and brown; T6 dark brown, medially interrupted in yellow. Phallus tubular and projected ventrally, in ventral view the phallus is 2x wider near the phallotrema section with the apical bulbous membranous structure, in lateral view the bulbous membranous structure is narrow and curved dorsally; the lateral margins of phallotrema are more sclerotinized surrounded by more membranous region; the phallus is micro-ornated dorsally and has smaller ornamentation in the membranous regions.

Description. Holotype. Head ( Figs.1A, C ): yellow with black and dark brown marks; eyes red, pubescent; face with a large, narrow prominent carina, black with transversal yellow band; scape light brown; pedicel basally brown, apically light yellow; flagellomere 1 brown, basally yellow, apically black, compressed, mango-shaped; arista with five dorsal and one ventral branches, and terminal fork; frons light yellow and brown; fronto-orbital plate yellow, dark brown mark from near the vertex adjacent to the frontal vitta to the base of the p rc frorb s; fronto-orbital setae black, a rc frorb s lateral and anterior of 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 = 0.08 mm; frontal vitta light brown, lighter near ptilinal suture; frontal triangle light yellow, large; ocellar triangle black, prominent; postocellar setae black, crossing; genae light yellow with a black ventral band along the ventral margin, a black spot in the margin of the eye near the vibrissae; palps dark brown to black, large; labellum black. Thorax ( Figs. 1B, C ): yellow with brown marks; scutum yellow with several brown marks, two longitudinal sub-medial brown bands anteriorly parallel converging medially near the transverse suture and, in height of dorsocentral setae, the bands fuse and are replaced by brown spots partially fused forming a triangle shape; fine gray line between the parallel brown marks; base of the notopleural and dorsocentral setae with brown spots; postpronotum light yellow; external margin of postpronotal lobe brown; transverse suture with a brown mark extended towards supra-alar area; six irregular rows of acrostichal setulae which become scarce posterior to the anterior dorsocentral setae; anterior dorsocentral setae about 2/3 the length of the posterior dorsocentral setae; scutellum dark brown, with yellow margins from its base until the base of the apical scutellar setae, dark spots at the base of the basal scutellar setae; basal and apical scutellar setae parallel, curved inwards; pleura yellow with brown marks; proepisternum black with ventral half light yellow; anepisternum brown with large yellow spot in its center; anepimeron yellow with dark brown spots; meron light brown, lighter at its dorsal margin. Wings ( Fig. 1F ): faint darker patch present bellow costal lappet; R 4+5 and M Parallel; R 2+3 slightly curved to costal at its tip; halter light yellow; index: C = 1.72, ac = 2.91, hb = 0.69, 4c = 1.52, 4v = 2.55, 5x = 2.41, M = 0.97, prox. x = 0.54. Length = 2.06 mm, width = 0.99 mm. Abdomen ( Figs. 1D, E ): tergites yellow with brown and black marks; T1 yellow, laterally black; T2 and T3 black, interrupted medially and sub-laterally in yellow; T3 black with two yellow marks in the medial dark areas; T4 yellow with a caudal black band interrupted sub-laterally in yellow, the black band is enlarged medially advancing towards the anterior margin, the band advances to the anterior margin laterally reaching it; T5 yellow, one large somewhat rounded caudal dark spot, lateral margin with small brown mark; sternites yellow; intersegmental membranes light. Terminalia ( Figs.2 , 89A ): epandrium with approximately equal width and length, with microtrichia, with seven (four at the right and three at the left side) upper and two lateral setae; ventral lobe narrow, glabrous, with one subapical and two long apical setae. Cerci not fused to epandrium, glabrous, and with large setae, hypoproctal plate present, ventral cecal lobes present with four setae each. Subepandrial sclerite wide, connecting the surstyli.Surstylus connected to the epandrium, with prensisetae arranged in a line, about four longer inner setae and four shorter outer setae. Hypandrium, longer than wider, shorter than epandrium. Pregonites large, fused to the hypandrium, with a seta near the fusion with the postgonite, not fused medially. Postgonites elongated and straight in lateral view, containing approximately three setulae near the fusion with pregonite. Phallotrema is roundish. Phallapodeme is slightly shorter than phallus, slightly curved ventrally. Body length: 2.09 mm.

Etymology. Named in reference to Itatiaia National Park, where the holotype was collected.
