03EC3E00FFAAF73061F2BFA5FF24BA00.taxon	discussion	Discussion. Lu et al. (2022) thought the specimen from Jiuwanshan, Guangxi was Apterolarnaca (Bianigryllacris) fallax (Liu & Bi, 2008). However, after examining the morphological graphs of type specimens of Apterolarnaca (Bianigryllacris) fallax (Liu & Bi, 2008), we thought the former was a new undescribed species. The new species differs from the latter by the posterior margin of female subgenital plate widely triangular in ventral view with a small angular in the middle instead of widely rounded (Fig. 12 G). The morphological illustrations have been provided by Lu et al. (2022) in Fig. 5.	en	Zhang, Qianwen, Luo, Yehong, Bian, Xun (2023): Contribution to the knowledge of Chinese Gryllacrididae (Orthoptera) XIX: New supplements to the genus Apterolarnaca Gorochov, 2004.
