Rectoris mutabilis (Lin, 1933)

  • Type locality: Yunkiang, Kweichow Province (presently Guizhou), Hsikiang River basin, China.

Note: acc. to Zhu et al. (2012) no present river in Kweichow ( = Guizhou) has been known by this name. Lin’s 'Yunkiang' means the 'Yun–Jiang' in Chinese, and the present Yun–Jiang is a tributary draining to the Liu–Jiang of the Pearl River drainage in Guangxi Province. Wu (1989) ever maintained that the ‘Yunkiang’ was the Rong–Jiang in Guizhou Province, but without further elaboration.

  • Holotype: ? SU 35261 (= CAS-SU 35261) [ex NSYU 35]; whereabouts unknown. Note: acc. to Zhu et al. (2012), the specimen labelled as the holotype of E. mutabilis in CAS-SU is not the type of R. mutabilis.
  • Paratypes (3): whereabouts unknown.
