Peckia (Peckia) rubella (Wiedemann)

( Figs. 3 , 81, 82 ) (fig. 98 in Aldrich 1916, figs. 293–295 in Roback 1954)

Sarcophaga rubella Wiedemann, 1830: 357 . Antigua [“Antigoa”]. Holotype male, in ZMUC (examined).

Sarcophaga capitata Aldrich, 1916: 209 . Puerto Rico, Mayaguez. Holotype male, in USNM (examined). N. syn.

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. Genal setae black dorsally, yellow or white ventrally. Occipital setae white or yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 3 (anterior one shorter), intra-alars = 1 + 2 (anterior one shorter), supra-alars = 2 + 3, basal scutellars = 3. Prosternum and posterior surface of hind coxa with black setae. 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 antero-dorsally 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 grey. ST1+3 with only black hair-like setae. Two lateral setae 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 anteriorly and long hair-like setae posteriorly. Syntergosternite 7+8 longer than high in lateral view, orange, without 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 curved, with a projection at about midlength. 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, 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, long, convergent in apical view, with a truncated apex in lateral view. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft, visible in lateral and apical view. Vesica very large, composed of two plate-like structures on each side connected proximally, with microtrichia dorsally.

Distribution. NEOTROPICAL—American Virgin Is., Antigua, British Virgin Is., Panama, Puerto Rico.
