A new genus record of Yasuhikotakia Nalbant, 2002 (Teleostei Botiidae) and a new species record of Brachydanio Weber et de Beaufort, 1916 (Teleostei Cyprinidae) to China

摘要

Two species of small freshwater fishes of Botiidae and Cyprinidae families of SE Asia were collected during field ichthyofauna surveys in lower Lancangjiang, Mekong basin before rain- ing season in 2015. Both Yasuhikotakia lecontei (Fowler, 1937) (Teleostei Botiidae) and Brachydanio rosea (Fang et Kottelat, 2000) (Teleostei Cyprinidae) are new records to China, and the genus Yasuhikotakia Nalbant, 2002 is firstly recorded in China. The occurrence of the two species in Xishuangbanna Prefecture, Yunnan Province is most likely a natural extension of their distributional range. The meristics and measurements of the specimens, diagnosis, photographs, radiographs and distribution map of the two newly recorded species are provided.
