Perla liui Wu, 1940: 331 . Holotype male (Yenching University, Beijing), Liang-ho-kou, Pao-Hsing, Sichuan Province, China.

Kamimuria liui: Wu, 1962: 143 ; Zwick, 1977: 116; Sivec, 1981: 252; Sivec et al., 1988: 32; Du et al., 1999: 64; Sivec & Stark,

2008: 137; Stark & Sivec, 2013: 117; Li & Li, 2022: 118.

Examined material. 1 male ( CAUC), China: Guangxi Zhuang Autonomous Region, Guilin City , Xing’an County, Mao’ershan National Natural Reserve , 1100–1600 m, 25.87 N, 110.42 E, 2003.VII.1, leg. Xingyue Liu ; 3 males, Guangdong Province, Nanling , 2005.VII.9–18, 24.92 N, 113.03 E, leg. Zaifu Xu.

Remarks. These males represent the first report of K. liui from southern China. However, we are not so sure about the identity of this species. Geographically, there are several common species in Guangxi and Sichuan ( Mo et al. 2022), including one species belonging to another perlid genus, Neoperla bilineata Wu & Claassen, 1934 , that is originally known from Sichuan and has been recently confirmed from Guangxi ( Mo et al. 2021). Thus, we could not exclude the possibility of Kamimuria specimens being K. liui . We still need the haplotype of K. liui from Sichuan Province to solve this problem because its holotype is considered lost ( Sivec et al. 1988).

These males have a slightly L-shaped aedeagus with an enlarged apex in lateral aspect ( Figs. 2f , 3f ), seemingly different from K. klapaleki Wu & Claassen, 1934 that has an aedeagus which is nearly right angled medially. Sivec (1981) identified specimens from Nepal and compared them with the specimens of neotypes of K. liui and provided new illustrations, but the apex of aedeagus seemed deformed or incompletely everted apically. The male from Guangxi has fewer sensilla on tergum 9 ( Fig. 2b ), but the mesal sclerite is of the same shape (comparing Figs. 2b , 3b with fig. 5d in Sivec 1981). Kamimuria liui has been recorded from several provinces of China, but it seems that only the type locality of Sichuan Province and Nepal have been confirmed ( Li & Li 2022). Morphologically, males from Guangdong and Guangxi share identical aedeagal shape and armatures ( Figs. 2d–f , 3d–f ), indicating that these specimens from southern China are at least conspecific and aedeagal characteristics could serve as safe characters for identifying correctly to species. Variation in color pattern ( Figs. 2a , 3a ), sensilla numbers ( Figs. 2b , 3b–c ), and the hemitergal lobe herein we considered as intraspecific.
