Distribution. Brazil (states of Amazonas, Pará and Rondônia), Colombia (department of Antioquia), Ecuador (region of Napo), Guyana (region of Upper Takutu-Upper Essequibo), Peru (department of Madre de Dios), Trinidad and Tobago (region of Diego Martin) and Venezuela (states of Amazonas, Aragua, Bolivar, Merida and Monagas).

Diagnosis. Ormiophasia causeyi can be distinguished from other species of Ormiophasia by clypeus darker than frontoclypeal membrane ( Fig. 5B View FIGURE 5 , 7B View FIGURE 7 ); head with silver pruinosity; scutum dark brown, contrasting with brown postpronotal lobe (9B, 11B and 13B); wing hyaline ( Fig. 17G View FIGURE 17 ); and apex of male cerci about 1/3 length of cerci ( Fig. 38B View FIGURE 38 ), rounded in posterior view and 1/3 width of cerci, gradually constricted. Ormiophasia causeyi , O. tavaresi sp. nov. and O. chapulini sp. nov. share a hyaline wing and darker body color, but can be clearly distinguished by the length and width of the apex of the male cerci as well as by epandrial characters. Of these three species, O. causeyi is the one with the narrowest apex of cerci (see Figs 38B View FIGURE 38 , 41C View FIGURE 41 , 42A View FIGURE 42 ). Female specimens of O. causeyi and O. chapulini sp. nov. are difficult to discriminate, but O. causeyi usually has arista weakly plumose ( Fig. 17B View FIGURE 17 ) rather than bare ( Fig. 36B View FIGURE 36 ).

Redescription of male. Body length 6.50–8.08 mm (mean = 7.25 mm); wing length 6.55–8.60 mm (7.37 mm) (n = 10).

Coloration. Head silver-pruinose ( Fig. 5B View FIGURE 5 ). Frontal vitta brown. Ocellar triangle dark brown. Fronto-orbital plate gray. Lunule yellowish-gray. Antenna brownish-orange. Parafacial gray. Gena, facial ridge and face brown. Mouthparts brown except clypeus (dark brown) and palpus (light brown). Occiput dark brown in upper area, becoming light brown in lower area. Thorax silver-pruinose ( Figs 9B View FIGURE 9 , 11B View FIGURE 11 ). Scutum dark brown; presutural scutum with three silver-pruinose stripes merged posteriorly after suture. Postpronotal lobe and lateral surface of thorax brown. Scutellum brown. Subscutellum dark brown. Wing hyaline. Tegula dark brown. Basicosta light brown. Veins dark brown. Halter and calypteres light brown. Legs brown. Abdomen entirely brown with silver pruinosity.

Head ( Figs 5B View FIGURE 5 , 17A, C View FIGURE 17 ). Circular in frontal view; ratio of head height/head width 1.00. Ocelli 1.5 times the diameter of dorsal ommatidia. Postocellar setae 2. Frontal vitta entirely or partially obliterated, subequal in width to ocellar triangle. Frontal setae 7–10, convergent, posterior ones shorter and weaker. Arista weakly plumose. First flagellomere 1.5 times longer than pedicel. Face subequal in width to facial ridge. Facial ridge 1.5 times wider than parafacial.

Thorax. Basisternum 0.76 times as high as wide ( Fig. 17E View FIGURE 17 ); median upper margin rounded, subtriangular. Prosternal tympanal membrane 0.75 times as high as wide. Proepimeral setae 2–3, upcurved. Anterodorsal corner of anepisternum with 1–2 weak setae, about 1/2 length of first notopleural seta; posterior row with 6–8 setae. Meral setae 6–9. Wing. Subequal to body length, three times longer than wide. Basicosta subequal in width to tegula. Base of vein R 4+5 with 2 dorsal and 2–4 ventral setae. Section of vein M between crossvein dm-cu and M 1 straight. Legs. Fore femur with row of 11–13 dorsal setae from base to apex and row of 12–16 posteroventral setae from base to apex. Fore tibia with row of four equally-spaced anterodorsal setae and 1 preapical seta. Mid femur with 2–3 posteroventral basal setae. Hind femur with row of 13–15 anterodorsal setae from base to apex and 3–4 anteroventral basal setae. Hind tibia with 2–3 posterodorsal median setae and 1 preapical seta.

Terminalia ( Fig. 38B View FIGURE 38 ). 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 tapered in lateral view; apex 1/3 width of cerci in posterior view, gradually constricted; apex with anterior surface slightly U-shaped. Postgonite slightly curved, apex tapered and rounded in lateral view.

Description of female. Differs from male as follows. Body length 6.25–8.83 mm (mean = 7.29 mm); wing length 6.91–9.23 mm (mean = 7.75 mm) (n = 10). Head ( Figs 7B View FIGURE 7 , 17B, D View FIGURE 17 ). Subtrapezoidal in frontal view; ratio of head height/head width 0.75. Frontal vitta 1.5 times width of fronto-orbital plate. Frontal setae 7–10, from lunule to posterior orbital proclinate seta; second or third anteriormost frontal seta stronger and subequal to subvibrissal setae. First flagellomere 2.7 times longer than pedicel. Face 1.4 times wider than facial ridge. Facial ridge 1.8 times wider than parafacial. Thorax. Basisternum 0.63 times as high as wide ( Fig. 17F View FIGURE 17 ); median upper margin rounded, subtriangular. Prosternal tympanal membrane elliptic, 0.70 times as high as wide. Wing 2.8 times longer than wide.

Remarks. The females were associated with the males by being from the same locality. The female of O. causeyi is described for the first time in the present study. In his key, Tavares (1964: 39) assigned to O. causeyi a dark scutum (“mesonoto enegrecido”). This was a valid diagnostic character when compared to the species available at the time. Ormiophasia morardi also has a dark scutum, but the holotype was not examined by Tavares. Along with these species there are also five new species with a dark scutum ( O. crassivena sp. nov., O. manguinhos sp. nov., O. tavaresi sp. nov., O. chapulini sp. nov. and O. buoculus sp. nov.). Therefore, the main diagnostic character of O. causeyi is not the color of the scutum but the shape of the male cerci. Ormiophasia causeyi seems to be restricted to the Amazon rainforest.
