Oxysarcodexia orbitalis Dodge, 1966

( Figs 204–206 )

Oxysarcodexia orbitalis Dodge, 1966: 686 ; Martinique, Mont Pélé , 2 km N Morne Range. Holotype male in USNM (examined from photographs).

Diagnosis. [Based on the original description ( Dodge 1966) and on photographs provided by Dr. Norman E. Woodley and Dr. Torsten Dikow (USNM).] Male. Length 6.5 mm. Postocular plate with golden pollinosity. Ocellar bristles weakly developed, hair-like. Proclinate fronto-orbital bristles present. Thorax black with yellowish-gray pollinosity on humeral region and laterally. Four well-differentiated post-sutural dorsocentral bristles. Apical scutellar bristles absent. Legs dark brown. Abdomen black with grayish pollinosity. T3 without median marginal bristles. Cercus elongate, sinuous in lateral view, with normal apex (i.e., as broad as median area) and straight margin; cercus with bristles ventrally over full length. Cerci with distal third as broad as middle part in posterior view; parallel, fused to apex, which is shiny black and with short yellowish pile distally. Pregonite strongly curved; unicolorous. Postgonite straight; unicolorous. Distiphallus compressed distally, with smooth ventroapical margin, conical apex, straight dorsal outline and small dorsoapical swelling. Vesica symmetrical, short; distal lobes reduced, “ear-shaped” (i.e., with distal lobes rounded), with bulbous base (lateral view), sclerotized, with spines.

Remarks. Oxysarcodexia orbitalis is reported as the only species in the genus presenting proclinate frontoorbital bristles in the male ( Dodge 1966). It should be stressed that the holotype is the only known specimen of this species, and therefore the proclinate fronto-orbital bristles could possibly be a teratological feature. See also remarks under O. cyanea . Female unknown.

Distribution. NEOTROPICAL. Martinique.

Biology. The holotype was collected on guava fruit ( Dodge 1966).

Type material examined. No specimens were examined directly, but photographs of the holotype were provided by courtesy of Dr. Norman E. Woodley and Dr. Torsten Dikow ( USNM) .
