Oxysarcodexia cingarus ( Aldrich, 1916) View in CoL

( Figs 70–72 View FIGURES 70–78 )

Sarcophaga cingarus Aldrich, 1916: 288 View in CoL ; USA, Pennsylvania, Natrona. Holotype male, female allotype, four male paratypes and one female paratype in USNM (none examined).

Sarcophaga cingaris: Hall (1929: 89) View in CoL , incorrect subsequent spelling of cingarus Aldrich, 1916 View in CoL .

Diagnosis. Male. Length 8.0–9.0 mm. Postocular plate with pale golden pollinosity. Ocellar bristles weakly developed. Thorax with pale golden pollinosity more evident laterally, same for the abdomen, T5 with golden pollinosity only laterally. Two well-differentiated posterior and 1–3 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs brownish. T3 with 3 pairs of lateral marginal bristles, T4 with 1 pair of median marginal and 2 pairs of lateral marginal bristles. ST5 with deep median cleft with margins almost parallel and with pilosity and bristles at apex of arms. Cercus with straight dorsal outline in lateral view, with pointed obliquely cut apex and dorsal subapical barb; with bristles ventrally only in distal third. Cerci with distal third narrower than middle part in posterior view; parallel and with a distinct constriction mid length. Pregonite with expanded base, gradually narrowing to apex; unicolorous. Postgonite with expanded base and sudden narrowing at apex; unicolorous. Distiphallus with smooth ventroapical margin, square/oblong apex and slightly sinuous dorsal outline. Vesica symmetrical, with angular median projection of main branch; distal lobes reduced, with filaments, tapering and sclerotized, without spines.

Remarks. The vesica of O. cingarus is one of the most simple and least ornamented within the genus ( Fig. 71 View FIGURES 70–78 ). The phallus resembles that of O. wygodzinskyi Lopes & Tibana, 1987 ( Fig. 71 View FIGURES 70–78 ), although the distiphallus apex is more sharp-angled in O. cingarus ( Fig. 282 View FIGURES 274–283 ); the vesica of O. cingarus is larger, and in O. wygodzinskyi ornamentation (spines) is present in the mid portion of the vesica (anterior view), and the distal half of the cercus is broader in posterior view and with a square tip in O. cingarus versus the slender distal half of cercus with pointed apex observed in O. wygodzinskyi . The female of O. cingarus has an undivided T7 ( Tibana & Mello 1985).

Distribution. NEARCTIC. Canada (Ontario, Quebec), USA (Arkansas, Colorado, Florida, Iowa, Kansas, Louisiana *, New Jersey, New York, Pennsylvania, South Carolina, Virginia *).

Biology. Adults of this species have been collected in association with pig carcasses exposed in trees as well as in the water ( Payne & King 1972). Predation of O. cingarus by the wasp Oxybelus uniglumis ( Linnaeus, 1758) ( Hymenoptera : Sphecidae ) was reported by Peckham et al. (1973).
