Remark. Efferia species B is similar to Ef. species A and Ef. bromleyi , but is distinguished from them by the combined characters of the terminalia (Fig. 52-54). The shorter epandrium, 2.4-2.6 times longer than wide, further distin- Figure 52-54. Male terminalia of Efferia sp. B , lateral guishes it from Ef. bromleyi .

The more angular dorsal process of the epandrium and the membranous posterior margin, capitate gonostylus, and angular phallic flange further separate it from both species.
