( Fig. 79 ) (figs. 24, 42, 46, 59, 67, 78 in Lopes 1958)

Peckia imperialis Robineau-Desvoidy, 1830: 335 . Cuba. Holotype male, possibly in MNHN (not examined). [Teste Evenhuis et al. (2010).] Sarcophaga praeceps Wiedemann, 1830: 355 . Cuba. Holotype male, in NMW (not examined). Sarcophaga hirtipes Walker, 1853: 321 . Colombia. [Junior primary homonym of Sarcophaga hirtipes Wiedemann, 1830 .]

Holotype male, in BMNH (not examined). Sarcophaga fortipes Walker, 1861: 310 . Haiti. Holotype male, in BMNH (not examined).

Description. Male. Head. Ocellar setae equal to or shorter than postoculars. Outer vertical seta stronger than postoculars. Black orbital setae. Four frontal setae situated below the dorsal limit of the lunule. Gena with white or yellow setae. First row of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 2, intra-alars = 1 + 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. ST1+3 with only black hair-like setae. One lateral seta on each side of T4. T5 with grey 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 straight. Inner margins of ST5 arms with a patch of short setae on the anterior region and long hair-like setae posteriorly. Syntergosternite 7+8 longer than high in lateral view, brown anteriorly and yellow posteriorly with golden microtrichosity. Epandrium bright orange. Cercus orange proximally and brown or dark brown distally. Cercus in lateral view progressively narrowing towards the apex. Dorsal margin of cercus slightly curved with smooth surface without a depression or tooth-like projection in lateral view. Cercal apex rounded 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, 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, as sclerotized as the phallic tube. Juxta with lateral plate, short and straight in lateral view, with outer margin uniform in apical view, and an acute apex. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft, visible in apical but not in lateral view. Vesica composed of two plate-like structures on each side connected proximally, with dorsal microtrichia.

Taxonomic remarks. The relative priority of Peckia imperialis Robineau-Desvoidy, 1830 over Sarcophaga praeceps Wiedemann, 1830 was discussed by Evenhuis et al. (2010).
