Material examined: Holotype male, labelled as follows: “ BRASIL, RS [=State of Rio Grande do Sul], Capão do Leão , Horto Botânico Ir. [=irmão] Teodoro Luis S 31º 48’ 58” W 52º 25’ 55” Armadilha [=Trap] Malaise 30x-23xi2018 Marinho e equipe [=and collaborators] col.”; “ Paramycodrosophila leonensis n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ MZUSP] . Holotype condition: Abdomen and head wrinkled.

Diagnosis. Flies yellow with brown and black marks forming a mottled pattern; head yellow and brown; scutum yellow and brown; pleura yellow with longitudinal brown bands; legs yellow; wings hyaline with a darkish apically pointy costal lappet; abdomen with yellow, dark brown and black, T1 light, other tergites dark brown to black. Phallus tubular, broad and projected ventrally; in ventral view the phallus is wider and round at the phallotrema section; the apex of the phallus is projected ventrally.

Description. Holotype. Head ( Figs. 21A, C ): yellow with brown marks; eyes greyish, pubescent; face brown; carina light yellow, narrow, prominent; scape yellow; pedicel yellow, apically lighter; flagellomere 1 brown, yellow apically, compressed, slightly mango-shaped; arista with five dorsal and one ventral branches, and terminal fork; frons brown and yellow; fronto-orbital plate yellow, brown spot at p rc frorb s; fronto-orbital setae black, a rc frorb s lateral 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; second half of frontal vitta brown; frontal triangle brown, large; ocellar triangle black, prominent; postocellar setae black, crossing; genae light yellow with light brown mark under the eye near the vibrissa, brown at the ventral margin; palps, labrum and labellum brown. Thorax ( Figs.21B, C ): yellow with brown marks; scutum mostly in shades of brown, one posteriorly round medial longitudinal yellow mark reaching half of scutum, slightly darker at the external margin of the yellow mark, fine longitudinal lighter band on the externally of dorsocentral row, darker mark near the transversal suture, mid acrostichal setulae with dark spots at its base outside the yellow mark; postpronotum lighter; six regular rows of acrostichal setulae, setulae absent after the anterior dorsocentral setae except for the mid pair of acrostichal; anterior dorsocentral setae smaller than posterior dorsocentral setae; scutellum light brown, slightly darker apically and at the basal setae; basal scutellar setae parallel; apical scutellar setae convergent, crossing; pleura light yellow with brown marks; proepisternum and anepisternum light yellow, dorsally brown forming a continual band with anepimeron and advancing posteriorly; katepisternum dorsal half brown; meron yellow. Wings ( Fig.21F ): faint darker patch present bellow costal lappet and above R 2+3; R 4+5 and M 1 parallel; R 2+3 slightly curved to costal at its tip, halter light yellow, basally yellow; index: C = 1.78, ac = 3.00, hb = 0.72, 4c = 1.34, 4v = 2.21, 5x = 2.60, M = 0.83, prox. x = 0.51. Length = 2.04 mm, width = 1.00 mm. Terminalia ( Figs. 22 , 89I ): epandrium is approximately equal width and length, with microtrichia, with eight upper and two lateral setae; ventral lobe short, glabrous, with two long apical setae and one short basal seta. Cerci not fused to the epandrium, with microtrichia, with large setae, hypoproctal plate present, ventral cecal lobes broad with setae. Surstylus with a row prensisetae dorsally, about five longer inner setae arranged and two smaller outer setae. Hypandrium, longer than wide, smaller than epandrium. Pregonites fused to the hypandrium, not fused medially, with a seta near the fusion to the postgonite. Postgonites short, very thick and wider near pregonite, containing at least three setulae near the fusion with pregonite. Phallotrema is large and round. Phallapodeme is smaller than phallus and sinuous. Body length: 1.59mm.

Etymology. Named in reference to the city of Capão do Leão, where the holotype was collected.
