Review of the subgenus Tachycines (Gymnaeta) Adelung, 1902 (Orthoptera, Rhaphidophoridae, Aemodogryllinae, Aemodogryllini) Author Qin, Yanyan Author Liu, Xianwei Author Li, Kai text Zootaxa 2019 2019-02-25 4560 2 273 310 journal article 27420 10.11646/zootaxa.4560.2.3 1b6492a4-da08-453c-942f-7bd80815962b 1175-5326 2627602 3867A9CC-9CA9-4512-A84C-ADC45CA47D80 Tachycines ( Gymnaeta ) proximus ( Gorochov, Rampini & Di Russo, 2006 ) ( Fig. 29 ) Diestrammena ( Gymnaeta ) ferecaeca proxima Gorochov, Rampini & Di Russo, 2006 .

Zootaxa , 2272: 28, Fig. 30 . ( syn. n. ) Distribution. China ( Guizhou : Libo)*. Discussion. The species is elevated here to independent species level from a subspecies of D. (G.) ferecaeca . Reasons: for the number of spines on hind tibiae differs greatly from those in T . ( G .) ferecaecus ( Gorochov, Rampini & Di Russo, 2006 ) , the male genitalia are also enough different to support a separation into two valid species. Furthermore, we think that T . ( G .) aspes ( Rampini, Di Russo & Cobolli, 2008 ) can be regarded as a synonym of Tachycines ( Gymnaeta ) proximus ( Gorochov, Rampini & Di Russo, 2006 ) as judging from their original descriptions and the male genitalia are almost the same. Specimen not studied.
