Material examined: Holotype 1 male, labelled as follows:“BRA [= Brazil] - RJ [= State of Rio de Janeiro] – PARNA [= National Park ] de Itatiaia (22°25’35.57”S, 44°37’14.6”W) Data: 06.xii.2020 - 21.xii.2020 Col.: Telles MHF; Vicenzi N OBS.: Armadilha [=Trap] Malaise”; “ Paramycodrosophila maculosa n. sp. Frech-Telles, Valente-Gaiesky, Gottschalk, ♂ Holotype ” [ MZUSP] . Holotype condition: There is a structure protruding from a mal-formed ptilinal suture.

Diagnosis. Flies dark brown and yellow; scutum mostly brown with lighter areas that, fused, resembles an uppercase “M”; mid acrostichal rows of setulae convergent with thicker setulae posteriorly; 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 a large black round costal lappet; abdomen with tergites yellow with brown marks; T6 yellow, laterally brown, faint caudal light brown enlarged medially and interrupted in yellow laterally.Posterior hypandrial process present. Postgonites “L”- shaped. Phallus tubular, projected ventrally, with two antero-posterior, round, more membranous projections dorsally.

Description. Holotype. Head ( Fig. 47A ): yellow with black and dark brown marks; eyes red, pubescent; face light yellow with dark brown marks near carina and genae; carina light yellow, large, prominent, narrow; scape yellow; pedicel light brown, apically lighter; flagellomere 1 black,basally yellow,compressed;arista with five dorsal and one ventral branches, and terminal fork; frons light yellow and brown; fronto-orbital plate brown, yellow band at the margin of the eye from the height of p rc frorb s towards the front; fronto-orbital setae black; distance between pc frorb s and a rc frorb s = 0.03 mm, between pc frorb s and p rc frorb s = 0.12 mm, and between a rc frorb s and p rc frorb s = 0.10 mm; frontal vitta brown, yellow anterior to fronto-orbital plate; frontal triangle light yellow with brown marks from the margins of ocellar triangle towards its external margins, large; ocellar triangle black, very prominent;postocellar setae black, crossing at the tip; genae yellow, black at the ventral margin and under the eye near the vibrissa; palps black, large; labrum light yellow; labellum black. Thorax ( Figs. 47B, C ): brown with darker marks; scutum brown with several dark brown marks, two parallel sub-medial longitudinal dark brown bands converging and fusing medially in height of anterior dorsocentral setae, greyish area between brown bands; fine yellow band external to the parallel brown bands external margin of postpronotal lobe dark brown; transverse suture with a dark brown mark extended towards supra-alar area; yellow areas posterior to the alar suture; base of the setae with dark brown spots except in postpronotum; postpronotum light yellow; four regular rows of acrostichal setulae, one additional acrostichal row on the left side consisting of three setulae, no acrostichal setulae posterior to anterior dorsocentral setae; anterior dorsocentral setae about 2/3the length of the posterior dorsocentral setae; scutellum dark brown with lighter spots anterior to apical scutellar setae; basal scutellar setae parallel, curved inwards;apical scutellar setae slightly convergent, curved inwards, crossing; pleura yellow with brown marks; proepisternum with dorsal half black; anepisternum yellow with dark brown dorsal and posterior margins, large brown spot at its center fusing partially with marks at its margins; anepimeron yellow with large brown transversal band; katepisternum dark brown with ventral half slightly lighter; meron brown; legs yellow with dark brown marks; coxae yellow with brown marks. Wings ( Fig. 47F ): faint darker patch present bellow costal lappet; R 4+5 and M 1 slightly convergent; halter light yellow; index: C = 2.04, ac = 3.35, hb = 0.58, 4c = 1.08, 4v = 1.81, 5x = 1.75, M = 0.56, prox. x = 0.45. Length = 2.41 mm, width = 1.06 mm. Abdomen ( Figs. 47D, E ): tergites yellow with brown marks; T1 brown, darker laterally; T2 brown, sub-laterally interrupted in yellow, faint long transversal yellow mark at anterior margin,yellow mark medially interrupted;T3 brown sub-laterally interrupted in yellow,yellow spot sub-laterally of the brown area;T4 brown interrupted sub-laterally in yellow, long transversal yellow band at the anterior margin, laterally the yellow band enlarges towards the posterior margin; T5 yellow, laterally brown, caudal brown band which enlarges medially towards the anterior margin, lateral of the brown band reaches toward the anterior margin almost reaching it; sternites tan; intersegmental membranes light. Terminalia ( Figs.48 , 91B ): epandrium is approximately equal width and length, with microtrichia, with 13 upper setae (11 at the inner margin [six at the right side and five at the left side] and two between the inner and outer margin dorsally); ventral lobe large, glabrous, with many long setae (around11).Cerci projected posteriorly,squarish in lateral view; not fused to the epandrium, with microtrichia,with very long setae, hypoproctal plate present, ventral cecal lobes small.Subepandrial sclerite sclerotinized.Surstylus with rows of many prensisetae and many inner and outer setae.Hypandrium,longer than wide; larger than epandrium with a large posterior hypandrial process.Pregonites fused to the hypandrium,not fused medially, with a seta near its internal margin.Postgonites slim and long,the ventral section of the postgonite connects with the pregonite near its anterior margin; the posterior sections of postgonites are asymmetrical and sinuous, narrower on its apex; the right side is more sinuous in ventral view;the posterior section of postgonite is longer than the ventral section. Phallotrema is slightly smaller than the rest of the tube of the phallus, it has a lateral indentation. Phallapodeme is smaller than phallus and very slightly curved ventrally. Body length: 2.54mm.

Etymology. Named in reference to mottled aspect of the fly.
