Oxysarcodexia cyanea Lopes, 1975 View in CoL

( Figs 96–98 View FIGURES 90–98 )

Oxysarcodexia cyanea Lopes, 1975d: 475 View in CoL ; Dominica, Trafalgar Falls . Holotype male (examined from photographs), female allotype and 32 female paratypes in USNM.

Diagnosis. [Based on the original description by Lopes (1975d) and on photographs provided by Dr. Torsten Dikow (USNM).] Male. Length 9.0 mm. Back of head gray and thorax gray. Ocellar bristles well developed. Two welldifferentiated posterior and 2 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs blackish. Abdomen grayish with silvery pollinosity, T4 without median marginal bristles. ST5 reddish brown. Cercus covered with many short yellow setulae, slightly curved at apex, which is blackish and obliquely cut. Cercus with bristles ventrally over full length. Cerci with distal third as broad as middle part in posterior view; parallel and with enlarged and blackish apices. Pregonite with expanded base, gradually narrowing to apex, which is expanded; unicolorous. Postgonite unicolorous. Distiphallus in lateral view with smooth ventroapical margins, conical apex; dorsal outline sinuous and with a small membranous area dorsally. Vesica large, symmetrical, partially membranous, with distal lobes bearing a few spines.

Remarks. The distiphallus of this species ( Fig. 97 View FIGURES 90–98 ) is similar to that of O. zayasi Dodge, 1956 ( Fig. 291 View FIGURES 284–292 ), but a notable difference is found in the cercus, which resembles that of O. orbitalis ( Fig. 205 View FIGURES 201–209 ) and which in turn differs from O. cyanea by the distinctive distiphallus, conical in posterior view and with rounded distal lobes of the vesica. Oxysarcodexia cyanea can be distinguished from O. aurata ( Fig. 40 View FIGURES 33–41 ) by the absence of a dorsoapical swelling of the distiphallus (referred to by Lopes (1975d) as a “large membrane on penis apex”). The female of O. cyanea has an undivided T7 ( Tibana & Mello 1985). The larvae of this species were described by Lopes (1975d).

Distribution. NEOTROPICAL. Dominica.

Biology. The original description mentions some specimens of O. cyanea collected on human feces and others collected in a Malaise trap, without further details ( Lopes 1975d).

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