(fig. 49 in Curran & Walley 1934)

Sarcophaga lithogaster Curran & Walley, 1934: 482 View in CoL . Guyana, Kartabo. Holotype male, in AMNH (not examined).

Description. Male. Head. Outer vertical seta same size as postoculars. Black orbital setae. Three frontal setae situated below the dorsal limit of the lunule. Genal setae black dorsally, yellow or white ventrally. 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), supra-alars = 2 + 3, basal scutellars = 3. Prosternum and posterior surface of hind coxa with black setae. White or yellow and black antero-ventral scutellar setae. Two 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 without a ctenidium. Antero-dorsal surface of mid tibia with 1 median seta and 1 apical seta. Hind tibia with 2 setae in the basal third, 1 in the middle third and 1 preapical on antero-dorsal surface. Abdomen. Postero-ventral seams between T3/T4 and T4/T5 parallel. Microtrichosity of the abdomen laterally grey and golden. ST1+3 with only black hair-like setae. Two lateral setae on each side of T4. T5 with golden microtrichosity. Posterior seam of T5 not projected posteriorly and ventrally, and normal setae in postero-ventral area directed posteriorly. Terminalia. ST5 orange. Medial margin of ST5 Λ- shaped. Inner margins of ST5 arms straight. Inner margins of ST5 arms with a patch of short setae on the median region and long hair-like setae posteriorly. 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 dorsal margin slightly curved in lateral view. Cercus with smooth dorsal surface without a depression or tooth-like projection. Cercal apex acute in lateral view. Surstylus orange, triangular, with a rounded apex, with postero-distal surface less sclerotized (more smooth; lighter and more transparent colour) than the remaining surface. Pregonite triangular, becoming narrower towards the apex, with a lateral projection, curved in lateral view, with a rounded apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta without demarcated connection with the phallic tube. Juxta with short lateral plate and membranous apical surface. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft, not enlarged distally, not visible in lateral view. Vesica composed of two plate-like structures on each side connected proximally.

Distribution. NEOTROPICAL— Guyana, Trinidad & Tobago ( Trinidad, Tobago).

Material examined. Trinidad: 1 male ( Sarcophaga lithogaster Curran & Walley, 1934 , paratype), Ortinola Estate Rd. 700ft., J. Smart B.M. 1937–778 ( MNRJ) .
