Remark. Efferia gossei is distinguished by the characters in the key and the combined characters of the terminalia (Fig. 24-26). Additionally, the apical margin of the wing in males is evenly contoured, not dilated, the apical margin of sternite 8 is produced, the anterior margin of gonocoxite is thumb-like apically, and the gonocoxal setae are short, slightly denser ventrally than dorsally. The dark brown or black femora will further separate both sexes from those of Ef. caudex and Ef. haloesa . The female is distinguished by the anterior scutal setae being less than the length of scape, black setae and 4-5 black marginal bristles of the scutellum, black femora, glossy black tergite 7, and the long terminalia, 6.3 mm.
