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 : 368-369

Leucophenga sujuanae sp. nov.

( Figs 3 G, 3H, 3I, 4C, 7)

Diagnosis. This species is similar to L. abbreviata in the patterns of abdominal tergites ( Fig. 4 C), but can be differentiated from it by having the black bands of abdominal second and third tergites discontinuous on posterior margins at least, sometimes also occur on fourth and fifth tergites ( Fig. 4 C), the pleura brownish yellow above, yellow below, sometimes with a small brown patch below base of wing ( Fig. 3 J), the aedeagus acute apically ( Fig. 7 C).

Description. Mesonotum mostly yellow ( Fig. 3 H). Scutellum mostly yellow, slightly brownish laterally, pale at tip ( Fig. 3 H). Halter mostly white ( Fig. 3 I). Male terminalia: Epandrium with sparse pubescence and ca. 9 setae near posterodorsal to ventral margins per side; apodeme slightly developed ( Fig. 7 A). Hypandrium with 1 long sensilla and ca. 4 sensilla subbasolaterally ( Fig. 7 B). Paramere slender, with a few minute sensilla distally ( Fig. 7 B).
