Peckia (Peckia) amoena (Aldrich)

( Fig. 83 ) (fig. 97 in Aldrich 1916, figs. 296–298 in Roback 1954)

Sarcophaga amoena Aldrich, 1916: 207 . Dominica. Holotype male, in USNM (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. Genal setae black dorsally, yellow or white ventrally. First row of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 3 (anterior one shorter), intra-alars = 1 + 2 (anterior one shorter), supraalars = 1 + 3, basal scutellars = 3. Prosternum and posterior surface of hind coxa with black setae. Black anteroventral 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 2 median setae 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. 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 on the anterior region and long hair-like setae posteriorly distributed. 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. Dorsal margin of cerci slighltly angled at about midlength in lateral view. Cercal apex acute in lateral view. Surstylus orange, triangular, with a bifid 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, without protuberances along the edge, with a bifurcated apex. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft, visible in lateral and apical views. Vesica composed of two plate-like structures on each side connected proximally, each with a subapical rounded lobe and an acute apex.

Variable features. Chaetotaxy: intra-alars = 2 + 2, supra-alars = 2 + 3. Antero-dorsal surface of mid tibia with 1 median seta and 1 apical seta. One lateral seta on each side of T4.

Distribution. NEOTROPICAL— Dominica.
