1. Occiput dorsally convex. Male tenth abdominal tergum normal, not specialized........................................................ 2
- Occiput dorsally flat. Male tenth abdominal tergum strongly specialized ................................................................... 3
2. Coloration greenish brown. Front part of head, i.e., frons, clypeus and labrum dark brown; occiput and pronotum with narrow dark longitudinal stripe. Tegmen with distinct dark spots, M vein and Cu vein black (Fig. 7a). Male cerci very simple, short, strongly curved and crossing each other, abruptly but not strongly constricted behind base half, apex shaped into a spine (Fig. 3d) .......................................................................................................................... ................................................................................................................................ Tapiena bivittata Hsia & Xia, 1992

Male cerci cylindrical, slightly curved, apical part enlarged, with a upcurved hook (Fig. 3 h) ........................................................................................................... Tapiena simplicis Liu & Xia, 1996
3. Male tenth abdominal tergum not compressed in lateral view; in dorsal view it slightly produced, with apical margin contracting with 4 spines (Fig. 4d, f) ................................................................... Tapiena quadridens Liu & Xia, 1996
- Male tenth abdominal tergum compressed in lateral view; in dorsal view, it produced backwards into a long median process........................................................................................................................................................................... 4
4. Medial process of male tenth abdominal tergum dorsally not concave, with apical part approximately truncated..... 5
- Medial process of male tenth abdominal tergum somewhat concave dorsally, with apical part concave .................... 8
5. Male tenth abdominal tergum with spiniferous dorsal surface in apical third part, and its ventral margin possessing several big spines; male cerci with apical part bispinose.............................................................................................. 6
- Apical part of male tenth abdominal tergum without spines or slightly spinous; male cerci only with one spine at apex ............................................................................................................................................................................... 7
6. Male tenth abdominal tergum with 4–5 big spines on ventral margin (Fig. 4 g). Female subgenital plate triangular on the whole, ventral surface in basal part symmetrically intumesced, lateral margins of distal part slightly concave, and apical margin obtuse (Fig. 4 k) .......................................................................... Tapiena spinicaudata Liu & Xia, 1996
- Male tenth abdominal tergum with 2–3 big spines on ventral margin (Fig. 4 m). Female subgenital plate pentagonal on the whole, with lateral margins of basal half part extending outwards, lateral margins of distal half part contracting and slightly convex, and apical margin emarginated (Fig. 4 q) ............ Tapiena parapentagona Liu & Kang, sp. n.
7. Size larger (length of male tegmen: 39mm; length of male posterior femur: 17.5mm). In dorsal view, male tenth abdominal tergum with short stick-like structure, apical margin with small symmetrical round lateral lobes (Fig. 4d). Female unknown ............................................................................................. Tapiena longzhouensis Liu & Yin, 2004
- Size rather smaller (length of male tegmen: 32mm; length male posterior femur: 16.5mm). In dorsal view, male tenth abdominal tergum with long stick-like structure, apical margin without small symmetrical round lateral lobes (Fig. 4 h). Female unknown ...................................................................................... Tapiena yunnana Xia & Liu, 1989
8. Male tenth abdominal tergum dorsally with an indistinct very narrow median longitudinal furrow in the basal third part; male cerci with obtuse apex.................................................................................................................................. 9
- Male tenth abdominal tergum dorsally thoroughly with a distinct wide median longitudinal furrow, which almost separated the tenth abdominal tergum into two symmetrical lobes (Fig. 6 o); male cerci with apex incurved into a triangular spine (Fig. 6 p) .......................................................................................... Tapiena bilobata Liu & Kang, sp. n.

Male stridulatory file on underside of left tegmen with about 240 fine teeth (Fig. 6a). Female subgenital plate triangular on the whole, with lateral margins slightly convex, and apical margin obtuse (Fig. 6 e) ..................... ................................................................................................................................................ Tapiena stridulous sp. n.
- Size much larger (length of male tegmen: 35.0 – 36.0mm; length of hind femur: 17.0mm). Male stridulatory file on underside of left tegmen with about 150 rather distinct fine teeth and about apical 25 indistinct teeth (Fig. 6b). Female unknown ................................................................................................ Tapiena hainanensis Liu & Xia, 1996
