Examined specimens.

Seven males, 59 females, China, Hunan Province, Xuefeng Mountains, Lingcuishan Park (27°54'N 110°34'E), 15 July 2019, alt. 214 m, slide prep. no. L2013-2015, DNA no. LCS2022-2024 and LCS2027.

Distribution.

China (Guangdong, Guangxi, Hong Kong, Hunan, Taiwan); Japan; Nepal; Hawaiian Islands.

Remarks.

This species has the body length of males 3.5-5.0 mm, and of females 4.5-7.5 mm. Karasawa (2016) redescribed and illustrated the morphological characters in detail. It can be distinguished by the characters of the male pleopod 1 endopodite (Fig. 5E ); however, morphological variations of the diagnostic characters have caused some taxonomic misinterpretation. Karasawa (2016) clarified the confusion through a combined morphological and molecular approach, and 11 species were considered to be junior synonyms of B. kathmandius . The present work identified the specimens from the Xuefeng Mountains by integrating morphological characters (Fig. 5A-E ) and a phylogenetic analysis (Fig. 1 ).
