Type locality. Brazil, Paraná, São José dos Pinhais.

Distribution. Brazil (states of Paraná, Rio de Janeiro and São Paulo).

Etymology. The name is a tribute to the great and historical Brazilian entomological collection of the Oswaldo Cruz Institute, unit of Manguinhos, and it is a reminder of the Manguinhos Massacre, one of the many horrible heritages of the Brazilian military dictatorship era. The name is a noun in apposition.

Diagnosis. Ormiophasia manguinhos  sp. nov. can be distinguished from other species of Ormiophasia  by head with silver pruinosity ( Figs 6DView FIGURE 6, 8CView FIGURE 8); clypeus darker than frontoclypeal membrane; thorax brownish-yellow and abdomen dark brown ( Figs 10DView FIGURE 10, 12DView FIGURE 12, 14CView FIGURE 14); basicosta broad, twice width of tegula ( Fig. 4BView FIGURE 4); male wing with weak infuscation at tip of vein R 1 and around veins R 2+3, R 4+5, M 1 and dm-cu ( Fig. 34FView FIGURE 34); female wing 2.4 times longer than wide, with strong infuscation around all veins ( Fig. 34GView FIGURE 34) except A 1 +CuA 2, veins R 2+3, R 4+5,M 1 and CuA 1 thickened, and section of vein M between crossvein dm-cu and M 1 strongly curved; apex of male cerci about 1/3 length of cerci ( Fig. 41BView FIGURE 41), rounded in posterior view and 3/5 width of cerci, gradually constricted. Ormiophasia manguinhos  sp. nov. is very similar to O. crassivena  sp. nov., especially concerning wing characters ( Figs 33View FIGURE 33 G–H). However, O. crassivena  sp. nov. has thorax and abdomen dark brown ( Figs 10CView FIGURE 10, 12CView FIGURE 12, 14BView FIGURE 14) and male wing with infuscation around veins R 1 and R 2+3 ( Fig. 33GView FIGURE 33). Additionally, the apex of the male cerci in O. crassivena  sp. nov. is longer ( Fig. 41AView FIGURE 41) than in O. manguinhos  sp. nov.

Description. Male. Body length 6.24 mm; wing length 6.72 mm (n = 1).

Coloration. Head silver-pruinose ( Fig. 6DView FIGURE 6). Frontal vitta brown. Ocellar triangle black. Fronto-orbital plate gray. Lunule yellowish-gray. Antenna yellowish-orange. Parafacial gray. Gena, facial ridge and face brown. Mouthparts brown except clypeus (dark brown). Occiput dark brown in upper area, becoming brown in lower area. Thorax silver-pruinose ( Figs 10DView FIGURE 10, 12DView FIGURE 12). Scutum brownish-yellow; presutural scutum with three silver-pruinose stripes merged posteriorly after suture. Postpronotal lobe and lateral surface of thorax brownish-yellow. Scutellum and subscutellum brownish-yellow. Wing with weak brown infuscation at tip of vein R 2+3 and weak brown infuscation around veins M 1 and dm-cu ( Fig. 34FView FIGURE 34). Tegula brownish-yellow. Basicosta and veins brown. Halter brownish-yellow. Calypteres light brown. Legs brownish-yellow. Abdomen entirely dark brown with silver pruinosity.

Head ( Figs 6DView FIGURE 6, 34A, CView FIGURE 34). Elliptic in frontal view; ratio of head height/head width 0.75. Ocelli subequal to dorsal ommatidia. Postocellar setae 2. Frontal vitta entirely obliterated. Frontal setae 6, convergent, posterior ones shorter and weaker. Arista bare. First flagellomere 2.3 times longer than pedicel. Face 1.3 times wider than facial ridge. Facial ridge 2.5 times wider than parafacial.

Thorax. Proepimeral setae 2, upcurved. Anterodorsal corner of anepisternum with 1 weak seta, about 1/2 length of first notopleural seta; posterior row with 7 setae. Meral setae 6. Wing. Subequal to body length, 2.7 times longer than wide. Basicosta twice width of tegula. Base of vein R 4+5 with 1 dorsal and 2 ventral setae. Section of vein M between crossvein dm-cu and M 1 straight. Legs. Fore femur with row of 10 dorsal setae from base to apex and row of 11 posteroventral setae from base to apex. Fore tibia with row of 3 equally-spaced anterodorsal setae and 1 preapical seta. Mid femur with 3 posteroventral basal setae. Hind femur with row of 14 anterodorsal setae from base to apex and 3 anteroventral basal setae. Hind tibia with 1 posterodorsal median seta and 1 preapical seta.

Terminalia ( Fig. 41BView FIGURE 41). Sternite 5 subrectangular; lateral distal lobes pronounced. Anteroventral epandrial process continuous with ventral epandrial margin. Dorsal surface of epandrium short, posterior margin higher than anterior margin; lateral ventral margin sharply curved; posterior area articulated to surstylus with closed, rounded arch. Surstylus stout, thicker than apex of cerci in lateral view; posterior outer surface covered with strong setae in upper two-thirds. Cerci: basal margin with distinct median projection; apex about 1/3 length of cerci, rounded in posterior view, narrow and pointed in lateral view; apex 3/5 width of cerci in posterior view, gradually constricted; apex with anterior surface U-shaped. Postgonite slightly curved, apex rounded in lateral view.

Female. Differs from male as follows. Body length 6.13–6.45 mm (mean = 6.30 mm); wing length 7.24–7.55 mm (mean = 7.45 mm) (n = 5). Head ( Figs 8CView FIGURE 8, 34B, DView FIGURE 34). Frontal vitta 1.5 times width of fronto-orbital plate. Frontal setae 6–8, from lunule to posterior orbital proclinate seta; second or third anteriormost frontal seta stronger and subequal to subvibrissal setae. First flagellomere 2.6 times as long as pedicel. Facial ridge 2.2 times wider than parafacial. Thorax. Basisternum 0.42 times as high as wide ( Fig. 34EView FIGURE 34); median upper margin rounded and long, subtriangular. Prosternal tympanal membrane elliptic, 0.75 times as high as wide. Wing 2.4 times longer than wide; with strong brown infuscation around all veins except A 1 +CuA 2 ( Fig. 34GView FIGURE 34). Vein R 2+3 thickened along it entire length, veins R 4+5 and M 1 thickened at level of crossvein r-m, and CuA 1 thickened at midlength. Section of vein M between crossvein dm-cu and M 1 strongly curved.

Remarks. The females were associated with the male through body color, infuscation of wing and size of basicosta. The description of the male prothorax was not possible, since there was only one specimen available for study. There is sexual dimorphism in the wing, the male lacking thickened veins and having weaker infuscation, whereas the female has thickened veins and strong infuscation. Ormiophasia manguinhos  sp. nov. and O. crassivena  sp. nov. are very similar (see Remarks under O. crassivena  sp. nov.). Ormiophasia manguinhos  sp. nov. seems to be restricted to the Atlantic Forest.
