► Eel loaches are a diverse and widespread group of freshwater fishes in Asia. ► We present the first comprehensive phylogeny showing a large undiscovered diversity. ► Eel loaches form three major species-groups and more than 30 species. ► The cladogenesis reflects events of vicariance and of faunal exchanges in Sundaland.
