description: Leucophenga acuticauda sp. nov.
(Figs. 2 H, 4E, 4F, 8H, 8I, 16)
Diagnosis. This species is mostly similar to L. cultella sp. nov. in having the wing fuscous along R1 and costa (Fig. 2 H, I), the color patterns of abdominal tergites in both male (Fig. 8 H, J) and female (Fig. 8 I, K), and the surstylus acute apically (Figs. 16, 17 A), but can be distinguished from the latter by the hypandrium with 1 sensillum (Fig. 16 B), and the aedeagus slightly ridgy submediodorsally (Fig. 16 D); see below that species.
Description. Ocellar triangle dark brown, with ca. 2 setae above ocellar setae. Frons yellow to brownish. Pedicel yellow to brownish yellow; first flagellomere yellowish. Clypeus brownish medially, dark brown laterally. Palpus yellow. Mesonotum brownish yellow, with four brownish to brown, longitudinal stripes submedially and laterally in male (Fig. 4 E), brownish before scutellum in female. Postpronotal lobe yellow (Fig. 4 F). Acrostichal setulae in ca. 6–8 irregular rows (Fig. 4 E). Scutellum dark brown, yellowish brown to brown at tip (Fig. 4 E). Pleura, katepisternum and meron mostly brown above (Fig. 4 F). Wing (Fig. 2 H): Costal vein between R2+3 and R4+5 distally with ca. 4–7 peg-like spinules on ventral surface. Abdominal tergites dark brown, with a pair of yellow patches submedially between 2nd to 3rd tergites in male (Fig. 8 H), entirely black in female (Fig. 8 I). Male terminalia: Epandrium with ca. 9 setae near posterior margin per side (Fig. 16 A). Paramere with ca. 5 sensilla submediodorsally (Fig. 16 C).
