Su, Yirui, Lu, Jinming & Chen, Hongwei, 2013, The genus Leucophenga (Diptera, Drosophilidae), part I: the abbreviata species group from the Oriental region with morphological and molecular evidence, Zootaxa 3637 (3), pp. 361-373 : 370

Leucophenga zhenfangae sp. nov.

( Figs 3 J, 3K, 3L, 4D, 8)

Diagnosis. This species is similar to L. brevivena sp. nov. in the patterns of abdominal tergites ( Fig. 4 D), but can be differentiated from it by having the mesonotum mostly yellow, the scutellum grayish yellow ( Fig. 3 K), the pleura yellow, slightly pale below ( Fig. 3 L), the aedeagus bifurcated from base to dorsal 1/3, round apically ( Fig. 8 C).

Description. Halter grayish yellow ( Fig. 3 L). Abdominal tergites brown; second yellow medially and along lateral margins; third and fourth each with distinct W-shaped patches medially ( Fig. 4 D). Male terminalia: Epandrium with pubescence except for anterior margin and ca. 10 setae near posterodorsal to ventral margins per side; apodeme developed ( Fig. 8 A). Hypandrium with 2 minute, sensilla subbasolaterally ( Fig. 8 B). Paramere slightly broadened, with a few minute sensilla distally ( Fig. 8 B).
