FIGURE 20. Ormiophasia costalimai Tavares , holotype ♂ (CEIOC). A. Lateral habitus. B. Head, frontal view. C. Left wing, ventral view. D. Head, lateral view. E. Labels. Scale bars: 1 mm. Diagnosis. Ormiophasia costalimai can be distinguished from other species of Ormiophasia by head with yellow pruinosity ( Figs 5C , 7C ); body brownish-yellow ( Figs 9C , 11C , 13C ); wing hyaline ( Fig. 19G ); and apex of male cerci about 1/3 length of cerci ( Fig. 38C ), rounded in posterior view and 1/3 width of cerci, abruptly constricted. Ormiophasia costalimai is very similar to O. inflata externally, although the male cerci and surstylus are very different. Usually, O. inflata ( Fig. 9E , 11E , 13E ) is stouter than O. costalimai . Additionally, the female head of O. costalimai is usually elliptic in frontal view ( Fig. 7C ), rather than subtrapezoidal ( Fig. 7E ). Redescription of male. Body length 7.07–8.66 mm (mean = 7.54 mm ); wing length 6.98–8.52 mm ( 7.39 mm ) (n = 6). Coloration. Head yellow-pruinose ( Fig. 5C ). Frontal vitta and ocellar triangle brown. Fronto-orbital plate and lunule brownish-yellow. Antenna yellowish-orange. Parafacial, gena, facial ridge, face and mouthparts brownishyellow. Occiput brown in upper area, becoming brownish-yellow in lower area. Thorax silver-pruinose ( Figs 9C , 11C ). Scutum brownish-yellow to light brown; presutural scutum with three silver-pruinose stripes merged posteriorly after suture. Postpronotal lobe, lateral surface of thorax, scutellum and subscutellum brownish-yellow. Wing hyaline. Tegula, basicosta, veins, halter and calypteres brownish-yellow. Legs brownish-yellow. Abdomen entirely brownish-yellow with silver pruinosity. Head ( Figs 5C , 19A, C ). Elliptic in frontal view; ratio of head height/head width 0.80. Ocelli 1.5 times the diameter of dorsal ommatidia. Postocellar setae 1–2. Frontal vitta entirely obliterated. Frontal setae 7–8, convergent, posterior ones shorter and weaker. Arista weakly plumose. First flagellomere twice length of pedicel. Face 1.3 times wider than facial ridge. Facial ridge 2.6 times wider than parafacial. Thorax. Basisternum 0.52 times as high as wide ( Fig. 19E ); median upper margin rounded and long, subrectangular. Prosternal tympanal membrane 0.76 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 7–8 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 2–3 dorsal and 2–4 ventral setae. Section of vein M between crossvein dm-cu and M 1 straight. Legs . Fore femur with row of 10–11 dorsal setae from base to apex and row of 14–17 setae from base to apex. Fore tibia with row of 4 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. 38C ). Sternite 5 subrectangular; lateral distal lobes weakly pronounced. Anteroventral epandrial process continuous with ventral epandrial margin. Dorsal surface of epandrium short, posterior margin higher than anterior margin; lateral ventral margin slightly curved; posterior area articulated to surstylus with open, round- ed arch. Surstylus stout, as thick as 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, thick and rounded in lateral view; apex 1/3 width of cerci in posterior view, abruptly constricted; apex with anterior surface V-shaped. Postgonite slightly curved, apex tapered in lateral view. Description of female. Differs from male as follows. Body length 6.10–8.52 mm (mean = 7.32 mm ); wing length 6.51–9.09 mm (mean = 7.80 mm ) (n = 10). Head ( Figs 7C , 19B, D ). Frontal vitta subequal in width to frontoorbital plate. Frontal setae 8–9, from lunule to posterior orbital proclinate seta; second or third anteriormost frontal seta stronger and subequal to subvibrissal setae. Thorax. Basisternum 0.48 times as high as wide ( Fig. 19F ); median upper margin rounded, subtriangular, with broad base. Prosternal tympanal membrane elliptic, 0.76 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. costalimai is described for the first time in the present study. In his key, Tavares made a confusion when assigning diagnostic characters to O. costalimai and O. travassosi (interpreted in the present revision as a junior synonym of O. inflata ) ( Tavares 1964: 39 ). Tavares (1964) assigned to O. costalimai surstylus (“forcipes inferiores”) with higher density of setae, mentioning that O. travassosi lacked this character. However, the drawings of the male terminalia of both species show exactly the opposite. Ormiophasia inflata ( Fig. 39B ) has a stouter and more setose surstylus than O. costalimai ( Fig. 38C ). This can also be verified in the male terminalia, mounted on slides, of paratypes of both species. Ormiophasia costalimai seems to be restricted to the Amazon rainforest.
