Oxysarcodexia molitor ( Curran & Walley, 1934)

( Figs 188–191 )

Sarcophaga molitor Curran & Walley, 1934: 488 ; Guyana, Kaieteur. Holotype male (examined from photographs), female allotype and two female paratypes in AMNH.

Diagnosis. [Based on the original description ( Curran & Walley 1934), the redescription by Lopes (1975c) and photographs provided by Dr. David Grimaldi (AMNH).] Male. Length 8.5–10.0 mm. Ocellar bristles weakly developed. Thorax and abdomen grayish with golden pollinosity more intense laterally on thorax and on T4, T5 golden yellowish. Two well-differentiated posterior and 2 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles present, although very small. Legs blackish. ST5 small with parallel cleft margins, with pilosity, and with small triangular projection on posterior part of arms. Cercus robust with truncated apex. Anterior area of the apical distiphallic plate largely membranous, with pair of spinous internal plates. Vesica strongly sclerotized with much-reduced distal membranous lobe.

Remarks. See under O. confusa . The female of O. molitor was described by Curran & Walley (1934), but structures of the female terminalia were poorly detailed (only reddish color of integument, golden abdominal pollinosity, and T6 (“first genital segment”) with sparse black setosity and a row of marginals). Tibana & Mello (1985) did not consider this species in their female grouping study and no illustrations were presented in the original description ( Curran & Walley 1934), preventing us from including O. molitor in any of the proposed female groups.

Distribution. NEOTROPICAL. Guyana.

Biology. The only available information is that the type specimens were collected on human feces ( Curran &Walley 1934).

Type material examined. No specimens were examined directly, but photographs of the holotype were provided by courtesy of Dr. David Grimaldi ( AMNH) .
