038E9570FFF1182CFE41FCF8E6EED9A8.taxon	discussion	REMARKS. The monotypic genus Dialarnaca was proposed by Gorochov (2005) for a type species from Vietnam. Later two species was described from the Hainan and Yunnan provinces of China (Shi et al., 2016). Herein one new species is described from Yunnan. A key to all known species of Dialarnaca is provided below.	en	Bian, Xun, Zhu, Qidi, Shi, Fuming (2017): Two new species of Gryllacridinae (Orthoptera: Gryllacrididae) from Yunnan, China.
