Scaptodrosophila curvata View in CoL sp. nov.
( Figs 5D–F View FIGURE 5 , 13 View FIGURE 13 )
Diagnosis. Body yellowish brown ( Fig. 5E, F View FIGURE 5 ); arista with five dorsal and four ventral branches in addition to terminal bifurcation ( Fig. 5D View FIGURE 5 ); hypandrium triangle shaped in ventral view; phallapodeme curved in lateral view ( Fig. 13C, D View FIGURE 13 ). This species exhibits the closest genetic affinity to S. latifoliacea sp. nov. in light of divergence in COI barcodes ( Table 2 View TABLE 2 ), but morphologically somewhat conflict with the diagnostic characters of the coracina species group.
Description. Head ( Fig. 5D View FIGURE 5 ): Frons brown. Pedicel yellowish brown. First flagellomere grayish. Facial carina brown, short, 1/3 the length of face.
Thorax ( Fig. 5E, F View FIGURE 5 ): Mesonotum yellow. Acrostichal setulae in ca. ten regular rows. Scutellum yellow. Pleura beige.
Abdomen ( Fig. 5E, F View FIGURE 5 ): Tergites II to V yellow with black caudal bands, the caudal bands on tergites II to V interrupted medially.
Male terminalia ( Fig. 13 View FIGURE 13 ): Epandrium with ca. 12 epandrial bristles near posterior and ventral margins per side. Surstylus with 8 peg-like surstylar teeth ( Fig. 13A, B View FIGURE 13 ). Hypandrium with a pair of paramedian hypandrial bristle. Pregonite with 3 sensilla medially. Phallus lacking pubescence ( Fig. 13C, D View FIGURE 13 ).
