(Figs 3 C, 3B, 4K, 4L, 9)
Leucophenga orientalis Lin & Wheeler, 1972: 249; Okada, 1989: 808.
Diagnosis. This species is somewhat similar to L. bellula in the pattern of abdominal tergites (Fig. 4 K, 4L), but can be distinguished from the latter by the 2nd abdominal tergite with brown patch (Fig. 4 K, 4L), and the scutellum yellow, with brown margin (Fig. 3 C).
Description. Male and female: Frons yellow to yellowish brown. Pedicel and first flagellomere mostly yellow. Palpus brown in male, dark brown in female. Mesonotum yellow (Fig. 3 C). Acrostichal setulae in ca. 12–14 irregular rows (Fig. 3 C). Postpronotal lobe yellow (Fig. 3 D). Pleura nearly yellow (Fig. 3 D). Halter yellowish (Fig. 3 D). Male terminalia: Epandrium with 10 setae near posterior margin and ventral corner per side (Fig. 9 A). Paramere with ca. 15 sensilla distally (Fig. 9 B). Aedeagus slender basally, with pubescence on distal 1/3 (Fig. 9 B).
