(Figs. 6–10)
Diagnosis. Miroculis (Miroculis) mocidade sp. nov. differs from the other species of Miroculis by the following characteristics in the male imago: 1) distomedial projection of compound eyes absent; 2) forewing with distal region washed with brown, hind wing with a tiny brownish spot on the base (Fig. 8); 3) forewing with vein A1 connected to A2; 4) forceps washed with brown; 5) forceps segment I with inner basal third narrowing abruptly, and inner subapical portion well broadened (Fig. 9); 6) penis broad basally, narrowing gradually toward apex; apex rounded (Fig. 10).
Description. Measurements (mm). Male imago. Body: 6.0; forewing: 5.0, angularity of cubital region 98°; hind wing: 1.2. Fore leg: broken off and missing, except for coxa, trochanter, femora and tibiae; mid leg: 2.7; hind leg: broken off and missing. Caudal filament: 11.7.
Ratios. Wings: Forewing width 0.5 x forewing length; hind wing length 0.3 x forewing length; hind wing width 0.5 hind wing length; fork on MA of forewing 0.5 x total length of MA. Genitalia: medial length of styliger plate 0.4 x maximum width of styliger plate; lateral length of styliger plate 1.2 x medial length of styliger plate; lateral length of styliger plate 0.7 x lateral length of segment IX. Forceps segment III 0.9 x segment II; segment III 0.4 x segment I; segment II 0.5 x segment I; penis length 1.2 x forceps segment I.
Coloration (Figs. 6–9). Body: brownish. Head. Brown. Compound eye with stalk orange, lighter toward apex; facets of upper portion orange, separated by brown grooves. Antenna: scape and pedicel brown, flagellum light brown. Thorax: brown, darker on margins. Wings (Figs. 7–8): forewings with hyaline membrane, distal region washed with brown, cross veins surrounded by small brown areas. Hind wing with hyaline membrane with a tiny brownish cloud on the base. Legs: pale; fore leg with femur and tibia washed with light brown, apex of femur with a brown band; mid leg with a brown band on apex; hind leg with a brown stripe on mid region and a brown band on apex. Abdomen: whitish washed with light brown, segments VIII–X washed with brown. Genitalia (Fig. 9): whitish washed with brown. Penis washed with dark brown. Caudal filament: whitish washed with light brown, lighter toward apex.
Morphology: Head: posterior margin V-shaped. Compound eye with upper portion on a short stalk (0.5 x longer than wide); distomedial projection of compound eyes absent; dorsal surface elliptic, with ten facets in the longest row. Lower portion of compound eye elliptic. Wings: forewing with five cross veins between C and Sc basal to bulla; 14–17 cross veins between C and Sc; IMP free basally; MP2 not or weakly connected to base of MP1 by cross vein; CuA connected to CuP by a cross vein subbasally; CuP and A1 connected by a cross vein subbasally; A1 connected to A2. Hind wing with apex slightly acute; fork of R+MA symmetrical; CuP present. Genitalia: Styliger plate with posteromedial margin concave. Forceps segment I with basal third broad tapering abruptly toward apex, and inner margin with subdistomedial portion broadened; inner and outer margins undulated. Penis broad narrowing gradually toward apex; apex rounded (Fig. 10); a row of spines on base of inner margin absent.
Etymology: The specific epithet of the new species derives from the locality where the imagos were collected: Serra da Mocidade National Park.
Distribution: Brazil: Roraima State.
Material examined: Holotype: male imago, BRAZIL, Roraima State, Caracaraí municipality, Serra da Mocidade National Park, 01°42"N / 61°27'W, 25.i–06.ii.2016, Mahlmann, T. col. (CZNC). Paratypes: one male imago, BRAZIL, Roraima State, Caracaraí municipality, Serra da Mocidade National Park, 01°42"N / 061°47'W, 25.i–06.ii.2016, Oliveira, M., Mahlmann, T. and Xavier, F.F. col. (UFRR); two male imagos, same data as holotype, except by 01°42’17.3”N / 061°47’14.1”W, 01–02.ii.2016, Nascimento, J.M.C. (INPA).
Comments. Miroculis (Miroculis) mocidade sp. nov. and Miroculis (Miroculis) fittkaui Savage & Peters, 1983 share a hyaline forewing which is pigmented in some parts of membrane especially around cross veins; and forceps segment I with subdistomedial broadened (Fig. 9). However, M. (M.) mocidade sp. nov. differs from M. (M.) fittkaui by displaying the hind wing with a tiny dark mark only in the base (Fig. 8) while in M. (M.) fittkaui the dark mark is in the base and the apex; by the forceps pigmented and pale in the inner margin of apical 2/3 of forceps segment I (Fig. 9), while M. (M.) fittkaui has only apex of forceps segment I; and by the shape of forceps segment I, M. (M.) mocidade has a short subdistomedial projection, with 1/ 4x length of forceps segment I, while M. (M.) fittkaui has a large subdistomedial projection, with 2/ 3x length of forceps segment I.
