Subfamily Tripetalocerinae Bolívar, 1887

Tripetalocerae Bolívar, 1887: 310; Hancock, 1907: 4; Günther, 1938a: 299. Tripetalocerini: Kirby, 1914: 11; Willemse, 1930: 6, 31.

Tripetaloceridae: Liang & Zheng, 1998: 21; Zheng, 2005: 14.

Tripetalocerinae: Steinmann, 1970: 215; Otte, 1997: 137; Mahmood et al., 2007: 1283. Discotettigini (partim): Kevan, 1966: 380.

Type genus: Tripetalocera Westwood, 1834 .

Diagnosis. The subfamily differs from all known subfamilies of Tetrigidae in strongly modified antennae and similar in this respect with Discotettiginae Hancock, 1907, but in latter subfamily antennae consist of 12–14 unarmed segments and only 2–4 pre-apical segments are foliaceous, while in Tripetalocerinae antennae consist of 8–11 segments and almost all segments (except 2–4 basal and 1–3 apical ones) are strongly widened and provided with apical projections (Figs. 1, 10, 24).

Composition. The subfamily includes two distinctly separated tribes, Tripetalocerini and Clinophaestini trib. nov.
