Scaptodrosophila curvata sp. nov.

(Figs 5D–F, 13)

Diagnosis. Body yellowish brown (Fig. 5E, F); arista with five dorsal and four ventral branches in addition to terminal bifurcation (Fig. 5D); hypandrium triangle shaped in ventral view; phallapodeme curved in lateral view (Fig. 13C, D). This species exhibits the closest genetic affinity to S. latifoliacea sp. nov. in light of divergence in COI barcodes (Table 2), but morphologically somewhat conflict with the diagnostic characters of the coracina species group.

Description. Head (Fig. 5D): Frons brown. Pedicel yellowish brown. First flagellomere grayish. Facial carina brown, short, 1/3 the length of face.

Thorax (Fig. 5E, F): Mesonotum yellow. Acrostichal setulae in ca. ten regular rows. Scutellum yellow. Pleura beige.

Abdomen (Fig. 5E, F): Tergites II to V yellow with black caudal bands, the caudal bands on tergites II to V interrupted medially.

Male terminalia (Fig. 13): Epandrium with ca. 12 epandrial bristles near posterior and ventral margins per side. Surstylus with 8 peg-like surstylar teeth (Fig. 13A, B). Hypandrium with a pair of paramedian hypandrial bristle. Pregonite with 3 sensilla medially. Phallus lacking pubescence (Fig. 13C, D).
