Sarcophaga chirotheca Hall, 1933: 266 . Panama, Canal Zone, Barro Colorado I. Holotype male, in AMNH (not examined).

Description. Male. Head. Ocellar setae stronger than postoculars. Outer vertical seta of same size as postoculars. Black orbital setae. Four frontal setae situated below the dorsal limit of the lunule. All genal setae black. 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 = 1 + 3, basal scutellars = 4. Prosternum and posterior surface of hind coxa with black setae. Black antero-ventral 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 or almost to its posterior margin. Mid femur with a ctenidium. Antero-dorsal surface of mid tibia with 1 median and 1 apical seta. Hind femur with a row of antero-ventral and a row of postero-ventral setae, male hind femoral organ without setae set in a patch. Hind tibia with 1 seta in the basal third, 1 in the middle third and 2 preapicals on antero-dorsal surface. Abdomen. Postero-ventral seams between T3/T4 and T4/T5 parallel. Microtrichosity of the abdomen laterally golden and grey. ST1+3 with only black hair-like setae. Four 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 ∩-shaped. Inner margins of ST5 arms convex. Inner margins of ST5 arms with a patch of short setae distributed at about midlength 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 distal half of the dorsal margin slightly curved in lateral view. Cercus without setae modified into spines ventrally. Cercal apex acute in lateral view, with an acute lateral projection. Surstylus brown, finger-shaped with anterior margin slightly projected towards the anterior body region, with a rounded apex. Pregonite tongue-shaped, curved in lateral view, with a lateral projection, with a rounded apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta with juxtal lateral plate with three juxtal horns. Basal horn long and straight, darker than the phallic tube. Distal two horns slightly curved. The bifurcation giving origin to the juxtal lateral plates is deep and leaves the lateral plates not very 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. Ocellar setae of same size as postoculars. First three rows of occipital setae black, others yellow. Chaetotaxy: dorsocentrals = 1 (close to the transverse suture) + 2, supra-alars = 1 + 2. Microtrichosity laterally on the abdomen only golden. Three lateral setae on each side of T4.

Distribution. NEOTROPICAL— Belize, Costa Rica, Panama, Venezuela.

Material examined. Costa Rica: 3 males, Guanacaste, Guan. Nat. Pk. Maritza Fld st., Casafran Trail , 600–1000m, 2–8.ix.1996, Gustafsson, Pape & Viklund ( ICN) .
