Oxysarcodexia floricola Lopes, 1975

( Figs 120–122 )

Oxysarcodexia floricola Lopes, 1975e: 487 ; Costa Rica, Guanacaste, 24 km NW Canas. Holotype male (depository unknown). [The original description only mentioned material belonging to Dr. E. R. Heithaus.]

Diagnosis. Male. Length 7.0 mm. Postocular plate with golden pollinosity. Ocellar bristles weakly developed. Thorax and abdomen with pale golden pollinosity. Two well-differentiated posterior and 2 smaller anterior postsutural dorsocentrals. Apical scutellar bristles absent. Legs blackish. T3 with 1 pair of lateral marginal bristles. Cercus sinuous in lateral view, with normal (i.e., as broad as median area), obliquely cut apex. 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; unicolorous. Postgonite with expanded base and sudden narrowing at apex; unicolorous. Distiphallus with smooth ventroapical margin, conical apex and straight dorsal outline. Vesica symmetrical, with angular median projection of main branch; distal lobes well developed, with filaments, tapering, sclerotized, with spines only along ventral margin.

Remarks. The single specimen examined presents a damaged abdomen, partially lacking T4 and entirely lacking T5 and ST5. Its terminalia are preserved in glycerin in a microtube. The original description mentions that T5 is yellow and that T4 lacks median marginal bristles, but there are no remarks regarding ST5 ( Lopes 1975e). The cercus of O. floricola ( Fig. 122 ) resembles that of O. laclaricola ( Fig. 162 ). See also remarks under O. cyaniforceps . Female unknown.

Distribution. NEOTROPICAL. Brazil (Santa Catarina ), Costa Rica.

Biology. The only available information is of this species visiting flowers ( Lopes 1975e).
