( Figs 132–134 View FIGURES 132–138 )

Sarcophaga galeata Aldrich, 1916: 280 View in CoL ; USA, Indiana, Lafayette. Holotype male and four male paratypes in USNM (not examined).

Diagnosis. Male. Length 7.0–8.0 mm. Postocular plate with silvery pollinosity. Ocellar bristles well developed. Thorax blackish with pale golden pollinosity more evident at humeral portion. Two well-differentiated posterior and 1–3 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs brownish. Abdomen blackish with some shades of pale golden pollinosity, T5 with golden pollinosity along the entire extension, although more intense at posterodorsal margin. T3 with 1 pair of lateral marginal bristles, T4 with no median marginal and 1 pair of lateral marginal bristles. ST5 with deep median V-shaped cleft, and with pilosity and bristles at apex of arms. Cercus sinuous in lateral view, with pointed obliquely cut apex and dorsal subapical barb. Cercus with bristles ventrally only in distal third. Cerci with distal third as broad as middle part in posterior view; parallel and with a distinct constriction mid length. Pregonite with expanded base, gradually narrowing to apex, which is darker than base. Postgonite with expanded base and sudden narrowing at apex; unicolorous. Distiphallus with smooth ventroapical margin, conical apex, straight dorsal outline, large dorsoapical swelling, and lateroapical expansions. Vesica symmetrical, with rounded median projection of main branch; distal lobes reduced, with filaments, tapering, sclerotized, with spines along margins.

Remarks. See under O. aurata . The first larval instar was described by Knipling (1936). Female unknown.

Distribution. NEARCTIC. USA (Alabama *, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, New York, Tennessee, Texas).

Biology. Oxysarcodexia galeata has been collected on high hilltops ( Dodge & Seago 1954) and in a wooded area, associated with a dog carcass ( Reed 1958). Immatures probably normally feed on feces; however, larvae obtained from one female were reared on decaying hamburger meat and they completed the development from larva to adult in 14 days ( Knipling 1936).
