description: Leucophenga quadripunctata (de Meijere, 1908)
(Figs 2 H, 6I, 6J, 10I, 10J, 14C, 14D, 24)
Drosophila quadripunctata de Meijere, 1908: 154; Okada, 1990: 683.
Diagnosis. Wing R2+3 vein with a short branch subapically (Fig. 2 H); paramere deeply concave mediodorsally (Fig. 24 C). This species is similar to L. cornuta sp. nov. in the wing R2+3 vein with a short branch subapically (see lower that species).
Description. Ocellar triangle brown, with 3–7 setae above ocellar setae. Frons yellowish brown to brown. Pedicel yellowish brown; first flagellomere yellow. Clypeus brown. Palpus brownish yellow. Mesonotum nearly yellowish brown, slightly brown before scutellum (Fig. 6 I). Postpronotal lobe yellow (Fig. 6 J). Acrostichal setulae in 13–15 irregular rows (Fig. 6 I). Scutellum yellowish brown, dark brown at tip and pale around apical scutellar setae (Fig. 6 I). Pleura with an unapparent, yellowish brown, longitudinal stripe above (Fig. 6 J). Katepisternum and mesopleuron mostly brownish (Fig. 6 J). Wing (Fig. 2 H): Costal vein between R2+3 and R4+5 distally with 5–8 peglike spinules on ventral surface. Halter slightly brownish apically (Fig. 6 J). Abdominal tergites brown to black, with yellow patches (Fig. 10 I, J). Male terminalia: Epandrium with pubescence near posterior and ventral margins and 6 setae near posterior margin per side (Fig. 24 A). Paramere with pubescence and 4 sensilla subapically (Fig. 24 C). Aedeagus pubescent apically (Fig. 24 D).
