Miroculis (Miroculis) cohnhafti  sp. nov. Raimundi & Nascimento

( Figs. 16–21View FIGURES 16 – 21)

Diagnosis. Miroculis (Miroculis) cohnhafti  sp. nov. differs from the other species of Miroculis  by the following characteristics in the male imago: 1) compound eye with upper portion on a stalk of intermediate length (approximately as long as wide); 2) distomedial projection of compound eyes present (little developed in some specimens) ( Fig. 16View FIGURES 16 – 21); 3) forewing with apical membrane between C and R pale ( Fig. 18View FIGURES 16 – 21); 4) veins A1 and A2 free ( Fig. 18View FIGURES 16 – 21); 5) forceps segment II with inner margin of apical portion broadened ( Fig. 20View FIGURES 16 – 21).

Description. Measurements (mm). Male imago. Body: 5.8; forewing: 4.6; angularity of cubital region 100°; hind wing: 1.2; fore leg: 4.0. Caudal filament: broken off and missing.

Ratios. Wings: Forewing width 0.4 x forewing length; hind wing length 0.3 forewing wing length; hind wing width 0.46 hind wing length; fork on MA of forewing 0.5 x total length of MA. Legs: fore leg segments: 1.1: 1.00: (1.70 mm) 0.08: 0.62: 0.47: 0.26: 0.14. Genitalia: medial length of styliger plate 0.4 x maximum width of styliger plate; lateral length of styliger plate 1.0 x medial length of styliger plate; lateral length of styliger plate 0.4 x lateral length of segment IX. Forceps segment III 0.8 x segment II; segment III 0.3 x segment I; segment II 0.4 x segment I; penis length 0.9 x forceps segment I.

Coloration ( Figs. 17–20View FIGURES 16 – 21). Body: brownish. Head. Orangish brown, with dark brown marks ventrally. Compound eye with stalk orange, lighter toward apex; facets of upper portion orange, separated by dark brown grooves. Antenna: scape yellowish, pedicel brown and flagellum whitish translucent. Thorax: brown, sutures darker; membranous areas yellowish. Wings ( Figs. 18–19View FIGURES 16 – 21): forewings with hyaline membrane; longitudinal veins brown, with C, SC and R darker; cross-veins brown, weakly developed. Hind wing with membrane hyaline; veins brown. Legs: Fore leg brownish; femur with medial blackish mark and subapical blackish band; tibia with a subapical blackish band. Mid and hind legs: coxae brown, remainder whitish brown; femora with a medial gray mark and subapical blackish band; tibiae with a subapical blackish mark. Abdomen: segments I – VI translucent brown, remainder orangish brown; terga with dark brown marks on medial and sublateral regions. Genitalia ( Figs. 20–21View FIGURES 16 – 21). Styliger plate brown, washed with orange–yellow. Forceps brown slightly washed with orange, except basal 2/3 of segment I and apical region of segment III light brown. Penis brown washed with yellow. Caudal filament: whitish brown, darker basally on each segment.

Morphology: Head: posterior margin V-shaped. Compound eye with upper portion on a stalk of intermediary length (approximately as long as wide); distomedial projection of compound eyes present; dorsal surface rounded, with 11 facets on the longest row. Lower portion of compound eye elliptic. Wings: forewing with three cross veins between C and Sc basal to bulla; 11 cross veins between C and Sc; IMP connected to MP1 and MP2 by a cross vein; MP2 connected to MP1 and CuA by cross veins; CuA connected to CuP by cross vein subbasally; veins A1 and A2 free. Hind wing with apex rounded, fork of R+MA symmetric, CuP present. Legs: fore tarsal claw different, one spine-like and other rounded. Genitalia: Styliger plate with posteromedial margin concave. Forceps segment I narrowing gradually toward apex without broad basal portion; inner and outer margins undulated; forceps segment II with inner margin broadened apically. Penis broad basally, narrowing toward apex; apex bifurcated ( Fig. 21View FIGURES 16 – 21): inner bifurcation short and acute; outer bifurcation longer and rounded; without row of spines on inner margin.

Etymology. This species is named in honor of Mario Cohn Haft, one of the organizers of the expedition to the Serra da Mocidade.

Distribution: Brazil: Roraima State.

Material examined: Holotype: male imago, BRAZIL, Roraima State, Caracaraí municipality, Serra da Mocidade National Park , 01°42’21.3”N / 061°47’04.7”W, 03–04.ii. 2016, Nascimento, J.M.C. col. ( INPAAbout INPA)GoogleMaps  . Paratypes: ten male imagos (same data as holotype) (five at INPAAbout INPA; five at CZNC)GoogleMaps  . Five male imago, BRAZIL, Roraima State, Caracaraí Caracaraí municipality, Serra da Mocidade National Park , 01°36.240"N / 061°54.370'W, 15–25.i. 2016, Boldrini, R., Barroso, P.C.S. and Xavier, F.F. col.

Comments: Miroculis (Miroculis) cohnhafti  sp. nov. shares some characteristics with Miroculis (M.) stenopterus Lima, Raimundi, Pinheiro & Salles, 2014  , Miroculis (M.) marauiae Savage & Peters, 1983  and Miroculis (M.) eldorado Gama-Neto & Hamada, 2014  . These four species have the upper portion of the compound eyes on a stalk, forewings are hyaline without any pigmentation, distomedial portion of styliger plate is concave, or concave to slightly straight in M. (M.) marauiae  , and hind wings are hyaline, but washed with brown on the base in M. (M.) stenopterus  , absent in M. (M.) marauiae  and in subcostal area in M. (M.) eldorado  . Otherwise, Miroculis (M.) cohnhafti  sp. nov. differs from these mentioned species above by distomedial projection of compound eyes present, while it is absent in the others species.
