( Fig. 20 ) (fig. 47 in Curran & Walley 1934, fig. 77 in Carvalho & Mello-Patiu 2008)

Sarcophaga pallidipilosa Curran & Walley, 1934: 483 . Guyana, Kartabo. Holotype male, in AMNH (not examined).

Description. Male. Head. Ocellar setae equal to or shorter than postoculars. Outer vertical seta stronger than postoculars. Black orbital setae. Three frontal setae situated below the dorsal limit of the lunule. Genal setae black anteriorly, yellow or white posteriorly. First row of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 4 (anterior two shorter), intra-alars = 2 + 2 (anterior one shorter), supraalars = 2 + 3, basal scutellars = 4. Prosternum and posterior surface of hind coxa with yellow or light brown setae. White or yellow and black antero-ventral scutellar setae. Three katepisternal setae. Postalar wall with white anterior setae. Lower calypter without dorsal 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 1 median and 1 apical seta. Ventral surface of hind femur with 1 row of setae. Hind tibia antero-dorsally with 1 seta in the basal third, 1 in the middle third and 1 preapical. Abdomen. Postero-ventral seams between T3/T4 curved anteriorly, so that segments are markedly longer dorsally than ventrally. Posterior seam of T5 projected posteriorly and ventrally. Microtrichosity of the abdomen laterally grey. ST1+3 with yellow or light brown hair-like setae. One lateral setae on each side of T4. T5 with grey microtrichosity. Postero-lateral area of T5 with setae directed towards the ventral body region. Terminalia. ST5 orange. Medial margin of ST5 Λ- shaped. Inner margins of ST5 arms straight. Inner margins of the ST5 arms with a patch of short setae on the median region and long hair-like setae uniformly distributed. Syntergosternite 7+8 as long as high in lateral view, orange, with golden microtrichosity. Epandrium bright orange. Cercus orange proximally and brown or dark brown distally. Cercus with a huge angled dorsal protuberance giving a triangular shape in lateral view. Cercus with setae on dorsal surface distributed apically, and an acute apex in lateral view. Surstylus orange, finger-shaped. Pregonite triangular, becoming narrower towards the apex, straight in lateral view, with an undulated apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Phallic tube curved and extremely elongated. Juxta with a demarcated connection with the phallic tube, without juxtal lateral plate. Juxta semi-sclerotized composed of two lobes. Juxtal base with an sclerotized accessory lobe hat-shaped. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft, not visible in lateral view. Vesica composed of two slender filaments, each strongly curved at mid length.

Variable features. Thoracic chaetotaxy: dorsocentrals = 0 + 3 (anterior one shorter).

Distribution. NEOTROPICAL— Brazil (Amazonas), Ecuador, Guyana, Surinam.
