Female prothorax (paratype). G. Male right wing, dorsal view (holotype). Scale bars: 1 mm. Type locality. Costa Rica , Puntarenas , Osa Peninsula, Corcovado National Park. Distribution. Colombia (department of Antioquia ) and Costa Rica (provinces of Alajuela , Cartago , Guanacaste , Heredia , Limón , Puntarenas and San José ). Etymology. The name is a tribute to the dipterist José Henrique Guimarães, for his important contributions to the taxonomy of Neotropical Tachinidae . The name is a noun in the genitive case. Diagnosis. Ormiophasia guimaraesi sp. nov. can be distinguished from other species of Ormiophasia by ocellar triangle setulose ( Figs 6A , 7H ); clypeus of same color as frontoclypeal membrane; scutum dark brown, contrasting with brownish-yellow lateral surface of thorax ( Figs 10A , 12A , 13H ); wing hyaline ( Fig. 31G ); surstylus stout ( Fig. 40B ), with posterior outer surface entirely covered with strong setae and posterior inner surface covered with short setae medially; and apex of male cerci about 1/3 length of cerci, subrectangular in posterior view and 3/5 width of cerci, abruptly constricted. Ormiophasia guimaraesi is very distinct from other Ormiophasia species, especially because of body color and male terminalia. Ormiophasia inflata also has stout male cerci and surstylus ( Fig. 39B ), but the apex of cerci and body color are completely different. Description. Male . Body length 6.99–9.28 mm (mean = 8.30 mm ); wing length 8.02–9.49 mm ( 8.74 mm ) (n = 10). Coloration. Head yellow-pruinose or silver ( Fig. 6A ). Frontal vitta brown. Ocellar triangle dark brown. Frontoorbital plate brownish-yellow to light brown. Lunule yellowish-gray. Antenna yellowish-orange. Parafacial, gena, facial ridge and face brownish-yellow. Mouthparts brownish-yellow. Occiput brown in upper area, becoming brownish-yellow in lower area. Thorax silver-pruinose ( Figs 10A , 12A ). Scutum dark brown; presutural scutum with three silver-pruinose stripes merged posteriorly after suture. Postpronotal lobe and lateral surface of thorax brownish-yellow. Scutellum and subscutellum dark brown. Wing hyaline. Tegula and basicosta brownish-yellow. Veins brownish-yellow to light brown. Halter and calypteres light brown. Legs brownish-yellow. Abdomen brownish-yellow at base, becoming dark brown after tergite three; with silver pruinosity. Sternites brownish-yellow. Head ( Figs 6A , 31A, C ). Elliptic in frontal view; ratio of head height/head width 0.75. Ocelli twice the diameter of dorsal ommatidia. Postocellar setae 2–4. Frontal vitta entirely obliterated. Frontal setae 5–9, convergent, posterior ones shorter and weaker.Arista bare. First flagellomere 2.4 times longer than pedicel. Face 1.3 times wider than facial ridge. Facial ridge 2.1 times wider than parafacial. Thorax. Basisternum 0.75 times as high as wide ( Fig. 31E ); median upper margin rounded and long, subrectangular. Prosternal tympanal membrane 0.75 times as high as wide. Proepimeral setae 2–3, upcurved. Anterodorsal corner of anepisternum with 1 weak seta, about 1/2 length of first notopleural seta; posterior row with 7–8 setae. Meral setae 5–8. Wing . Subequal to body length, three times longer than wide. Basicosta subequal in width to tegula. Base of vein R 4+5 with 2–4 dorsal and 3–4 ventral setae. Section of vein M between crossvein dm-cu and M 1 straight. Legs . Fore femur with row of 10–14 dorsal setae from base to apex and row of 14–17 posteroventral 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. 40B ). Sternite 5 subtrapezoidal; lateral distal lobes pronounced. Anteroventral epandrial process continuous with ventral epandrial margin. Dorsal surface of epandrium short, posterior margin at same level as 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 entirely covered with strong setae; posterior inner surface covered with short setae medially. Cerci: basal margin slightly curved, without a distinct median projection; apex about 1/3 length of cerci, subrectangular in posterior view, narrow and tapered in lateral view; apex 3/5 width of cerci in posterior view, abruptly constricted; apex with anterior surface V-shaped. Postgonite slightly curved, apex tapered in lateral view. Female. Differs from male as follows. Body length 7.56–9.17 mm (mean = 8.33 mm ); wing length 8.30–10.35 mm (mean = 9.24 mm ) (n = 10). Head ( Figs 7H , 31B, D ). Frontal vitta subequal in width to fronto-orbital plate. Frontal setae 8–9, from lunule to posterior orbital proclinate seta; second or third anteriormost frontal seta stronger and subequal to subvibrissal setae. First flagellomere 2.1 times as long as pedicel. Thorax. Basisternum 0.53 times as high as wide ( Fig. 31F ); median upper margin rounded, subtriangular. Prosternal tympanal membrane elliptic, 0.68 times as high as wide. Remarks. The females were associated with the males through body color. The proposition of this new species is justified especially by the shape of the male terminalia. None of the valid species of Ormiophasia known to date has a stout surstylus with posterior inner surface covered with short setae and apex of male cerci subrectangular in posterior view. Regarding the distribution of O. guimaraesi sp. nov. , nearly all the examined material was collected in Costa Rica , except for one female from Colombia . This may suggest a more continuous distribution between these two countries.
