Efferia caymanensis Scarbrough 1988: 150 .

Types examined. CAYMAN ISLANDS: Grand Cayman BWI / E. Foldmans Bay / 27.ii.1970 / E.J. Gerberg (holotype m, USNM) . Paratypes: Grand Cayman BWI / Boatswain Point / Lime Tree Estate / 16.ii.1985, E.J. Gerberg (allotype f, USNM) ; same data as allotype except 27.ii.1987; Grand Cayman BWI / Vicksville / NW Pt. 17.viii.1975 / E.J. Gerberg (2 f, USNM, EJGC) .

Distribution. Grand Cayman Island; February and August.

Remark. Efferia caymanensis is readily distinguished by the red color of the body, wing venation, dense parted setae on tergites 2-4, and male terminalia, especially the small truncate apical process on the epandrium and the narrow style-like gonocoxite (Fig. 17, re-illustrated from Scarbrough 1988). This is the only species of Efferia in West Indies that belongs to the staminea group (see Fig. 3).
