Leucophenga todai Sidorenko, 1991: 403.
Diagnosis. This species is similar to L. trivittata Okada, 1990 from Thailand in the patterns of abdominal tergites (Fig. 8 D), but can be distinguished from the latter by having the wing pattern (Fig. 2 D) and katepisternum mostly brown (Fig. 4 H). In L. trivittata, the wing with distinct dark patches on base, r-m vein and antero-middle (Fig. 1 A in Okada 1990), the katepisternum yellow.
Description. Ocellar triangle dark brown, with ca. 2–7 setae above ocellar setae. Frons yellowish brown to brown. Pedicel yellow; first flagellomere brownish yellow. Clypeus yellowish brown. Mesonotum yellowish brown medially, brown laterally, with 2 broad, brown longitudinal stripes submedially (Fig. 4 G). Postpronotal lobe yellowish. Acrostichal setulae in ca. 13–15 irregular rows (Fig. 4 G). Scutellum brown, pale on tip (Fig. 4 G). Meron brown (Fig. 4 H). Wing (Fig. 2 D): Costal vein between R2+3 and R4+5 distally with ca. 7 peg-like spinules on ventral surface. Mid and hindlegs dark brown to black on knees. Abdominal tergites dark brown to black, thin yellow along all margins (Fig. 8 D); second broadly yellow medially; third with a pair of narrow, yellow patches submedially along anterior margin; fourth and fifth with 2 pairs of yellow patches submedially along or near anterior margins; sixth with a pair of yellow patch submedially. Male terminalia: Epandrium with ca. 9 setae near dorsal and posterior margins, and ca. 5 setae on ventral corner per side (Fig. 17 A). Hypandrium with 1 sensillum (Fig. 17 B). Paramere thin on basal 1/3, with ca. 4 sensilla and pubescence distally (Fig. 17 C). Aedeagus mostly reticulated, distally curved ventrad and with a dorsal, small projection (Fig. 17 D).
