Siphona perispoliata group Diagnosis. Abdomen. Shining black in ground color; tergite 3 without median marginal setae; male sternite 5 (Figs 4, 8) with a pair of developed apical lobes bearing pointed inner process. Male postabdomen (Figs 1–3, 5–7): pregonite fused with hypandrium at base, without seta; postgonite lacking. Female postabdomen (Figs 9–10): tergite 8 narrowly fused with each other in anterodorsal part; sternite 8 with some strong setae. Remarks. The character states described above are peculiar and thus are considered apomorphic. Siphona (Aphantorhaphopsis) expleta sp. nov. and S. (A.) perispoliata belong to this group and are distributed in the Oriental Region.
