Leucophenga interrupta

Huang, Jia, Li, Tong & Chen, Hongwei, 2013, The genus Leucophenga (Diptera, Drosophilidae), part III: the interrupta species group from the Oriental region, with morphological and molecular evidence, Zootaxa 3750 (5), pp. 587-600 : 599

Key to species of the interrupta group

1. Wing with broad, dark longitudinal stripe along anterodistal portion ( Fig. 2 A, D, G, J, M); paramere with wrinkles ( Figs. 4 D, 5C, 6C, 7C, 8C); aedeagus with sclerotized processes basolaterally ( Figs. 4 E, 5D, 6D, 7D, 8D)........ interrupta group ... 2

- Wing without broad, dark longitudinal stripe along anterodistal portion; paramere lacking wrinkles; aedeagus without processes basolaterally............................................................... other Leucophenga species

2. Aedeagus slightly acute apically, with a pair of strong and acute processes subbasally ( Fig. 4 E).............. L. interrupta

- Aedeagus neither acute apically nor acute processes subbasally................................................. 3

3. Parameres with 3 serrated processes subapially (Fig. 53C); aedeagus with 1 regular row (ca. 5) of serrated processes distally, the basolateral process shorter than half of aedeagal length (Fig. 53D)............................... L. neointerrupta

- Parameres lacking serrated processes subapially ( Figs. 6 C, 7C, 8C); aedeagus lacking regular row of serrated processes distally, the basolateral process nearly as long as aedeagus ( Figs. 6 D, 7D, 8D)...................................... 4

4. Aedeagal basolateral process broadened, distally with several serrated processes on dorsal portion ( Fig. 8 D)........................................................................................................ L. retifoliacea

- Aedeagal basolateral process slender, distally lacking several serrated processes ( Figs. 6 D, 7D)....................... 5

5. Paramere curved to cucullate, subbasally with several serrated processes on inner margin ( Fig. 6 C); aedeagus not reticulated, the basal process slender, longer than aedeagus, slightly curved submedially, and slightly bifurcate apically, lacking serrated processes ( Fig. 6 D)........................................................................... L. bifurcata

- Paramere expended and slightly oblong, lacking serrated processes and sensillum ( Fig. 7 C); aedeagus reticulated basally, the basolateral process broadened, distally with several serrated processes on dorsal portion ( Fig. 7 D)......... L. quadrifurcata
