Purun; Sg. Tiang); Shafiq et al., 2014: 827 (Sg. Kurau); Authors' data (Lata Perahu; Pondok Tanjung; Sg. Ulu Kampar).   Remarks.  Channa gachuaregularly cited in many papers may be erroneous according to Conte-Grand et al.(2017). They propose that the species is involved in a complex of two widespread phylogenetic lineages. They advise that  C. gachuashould be used for describing specimens encountered in Bangladesh, India, Nepal, Sri Lankaand Myanmar( Rakhineregion) and  C. limbatashould be applied for specimens occurring in Myanmartowards Vietnam, southern China, Thailand, Peninsular Malaysiaand Indonesia. Until further clarification emerges, our checklist adopts  C.aff. gachuafor specimens found in Perak.
