All specimens had their post-abdomen dissected GoogleMaps   .

Type locality. Caxiuanã National Forest, municipality of Melgaço, state of Pará, Brazil (01°44'14"S, 51°27′25″W).

Diagnosis. Pleurae without a dark strip below postpronotum and wing base ( Fig. 14 View FIGURES 14–17 ). Epandrium with large setae in ventral lobe and surstylus with 5 peg-like prensisetae and a crescent process dorsal to prensisetae ( Fig. 18 View FIGURES 18–23 ). Aedeagus arrow-shaped with tip membranous and bearing two subapical lateral spurs, with three overlapping bends apically ( Figs. 21–23 View FIGURES 18–23 ).

Description. ♂. Head ( Figs. 16–17 View FIGURES 14–17 ). Yellow. Frons and face yellow, fronto-orbital plates indistinct with the same color of the frons (as in H. rondonia   sp. nov.). Length ratio of mid to anterior orbital setae = 0.42 (0.33–0.50), length ratio of mid to posterior orbital setae = 0.44 (0.33–0.56), vt index = 1.20, ocellar triangle yellowish about 35% (26–46%) of frontal length. Facial carina not prominent, with the same color of the frons. Antennae yellowish with flagellomeres slightly grey, aristae with 4–5 dorsal and one ventral branches, plus terminal fork. Palpus yellowish with an apical seta and two or three smaller preapical setae. Red eyes with short piles. Genae yellow, first genal setae about 17% (16–18%) of the vibrissae length. Cheek index = 0.20 (0.15–0.24), eye index = 1.13 (1.11– 1.16).

Thorax ( Fig. 14–15 View FIGURES 14–17 ). Yellow. Length = 0.65 (0.60–0.68) mm, width = 0.51 (0.50–0.53) mm, 6 irregular rows of acrostichals, no prescutellar setae. Dc index = 0.44 (0.44–0.44). Scutellum yellow. Basal scutellar setae convergent. Scut position index = 0.73 (0.70–0.80). Two prominent katepisternal setae and a row of setulae between them. Anterior katepisternal about 51% (38–60%) of the length of posterior one. Pleurae and legs yellow.

Wings ( Fig. 45 View FIGURES 44–47 ). Yellow with veins dark yellow. Length = 1.25 (1.04–1.37) mm. Length to width ratio = 0.63 (0.60–0.67). Indices: C = 1.52 (1.33–1.75); 4v = 1.67 (1.50–1.92); 5x = 2.52 (2.00–3.00); 4c = 1.26 (1.12–1.38); M = 0.63 (0.56–0.72); hb = 2.02 (1.80–2.28); prox. x = 0.41 (0.37–0.46).

Abdomen. Main color yellow. Tergites II–V with fainted brown posterior marginal bands not reaching lateral area.

Body length = 1.38 (1.27–1.52) mm.

Terminalia ( Figs. 18–23 View FIGURES 18–23 ). Epandrium microtrichose, with four upper and 14 lower setae, 11 of lower ones located on ventral lobe ( Fig. 18 View FIGURES 18–23 ). Cerci microtrichoses, not fused with epandrium. Surstylus not microtrichose, with 5 peg-like prensisetae, two smaller setulae following prensisetae row, about 10 inner and no outer setae. Surstyli not covered by ventral lobe of epandrium. Decasternum broad ( Fig. 20 View FIGURES 18–23 ). Hypandrium with the anterior margin wider than in Hirtodrosophila rondonia   sp. nov., gonopods fused with hypandrium, each bearing a seta near outer margin ( Fig. 19 View FIGURES 18–23 ). Paraphysis with 5 upper and 3 median small setulae on inner margin. Aedeagus arrow-shaped with a membranous tip, subapical portion convex in lateral view. Lateral outwards spurs (as in H. subgilva   ) with three small overlapping bends ( Fig. 21–23 View FIGURES 18–23 ). Aedeagal apodeme fused with and shorter than aedeagus.

♀. Unknown.

Etymology. The name “nungara” means “similar” in the Tupi-Guarani language and it is an allusion to its similarity with H. gilva   .

Geographic distribution. Hirtodrosophila nungara   sp. nov. was found in two areas from the Brazilian Amazon biome, at the Floresta Nacional de Caxiuanã, municipality of Melgaço, state of Pará (01°47'32.3"S; 01°26′2.5″W) and at the municipality of Colorado do Oeste, state of Rondonia (13°00'37.7"S; 60°35'24.9"W) ( Fig. 1 View FIGURE 1 ).
