Sarcophaga tridentata Hall, 1937: 209 . Brazil, Obrilonys. Holotype male, in USNM (examined).

Description. Male. Head. Ocellar setae equal to or shorter than postoculars. Outer vertical seta of same size as postoculars. Black orbital setae. Three frontal setae situated below the dorsal limit of the lunule. Genal setae black anteriorly, yellow or white posteriorly. First two rows of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 3 (anterior one shorter), intra-alars = 2 + 2 (anterior one shorter), supraalars = 1 + 3, basal scutellars = 4. Prosternum and posterior surface of hind coxa with black setae. Black anteroventral scutellar setae. Three katepisternal setae. Postalar wall with only black setae. Lower calypter with a central dark spot and a fringe of long hair-like setae along outer margin, extending to its posterior margin. Mid femur with a ctenidium. Antero-dorsal surface of mid tibia with 2 median setae and 1 apical seta. Hind femur with a row of antero-ventral and a row of postero-ventral setae. Hind tibia with 1 seta in the basal third, 1 in the middle third and 1 preapical. Abdomen. Postero-ventral seams between T3/T4 and T4/T5 parallel. Microtrichosity of the abdomen laterally golden. ST1+3 with only black hair-like setae. Three lateral setae on each side of T4. Posterior seam of T5 not projected posteriorly and ventrally, and normal setae in postero-ventral area directed posteriorly. T5 with golden microtrichosity. Terminalia. ST5 orange. Medial margin of ST5 ∩-shaped. Inner margins of ST5 arms convex. Anterior region of the inner margins of ST5 arms with long hair-like setae. Median region of the inner margins of ST5 arms with a patch of short setae. Syntergosternite 7+8 longer than high in lateral view, orange, with golden microtrichosity. Epandrium bright orange. Cercus orange proximally and brown or dark brown distally. Cercus in lateral view progressively narrowing towards the apex, with the distal half slightly curved and a ventral projection at about midlength, near apex. Cercal apex rounded in lateral view, with more than 5 strongly developed ventral spines. Surstylus orange, finger-shaped with anterior margin slightly projected towards the anterior body region, with a rounded apex. Postgonite elongated, with a hooked apex. Pregonite tongue-shaped, curved in lateral view, with an undulated apex. Basi- and distiphallus connected by a desclerotized strip. Juxta with juxtal lateral plate with three juxtal horns. Basal horn is longer than the others. The bifurcation giving origin to the juxtal lateral plates is superficial at the juxtal apex and leaves the lateral plates close to each other. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft. Short vesica composed of one entire plate without demarcated connection with the distiphallus.

Variable features. Median katepisternal seta duplicated on both sides. Basal scutellars irregular, with 4 on the right side and 3 on the left.

Distribution. NEOTROPICAL— Brazil (Mato Grosso, Minas Gerais), Colombia (Amazonas, Meta), Ecuador.
