Lepidocephalus is a genus of loaches native to rivers in the Southeast Asian countries of Indonesia, Malaysia and Thailand and Manipur, north east India. Members of this genus are known as "spirit loaches".[1] They resemble the related kuhli loaches and Lepidocephalichthys loaches (some species in the latter genus were formerly placed in Lepidocephalus), but are more robust and generally found deep in large rivers.[1] With little or no light in their habitat, their eyes and pigmentation are reduced to various extent. One species, L. spectrum, completely lacks pigment and eyes, similar to cavefish.[1] They are generally poorly known, but based on the relatively few scientific museum specimens they can reach up to 8 cm (3.1 in) in standard length.[1]
