Two new species of Mastacembelus from Myanmar (Teleostei: Synbranchiformes: Mastacembelidae)

Mastacembelus tinwini, new species, from streams in the Mon and Kayin States of southern Myanmar, is distinguished from its congeners by a unique colour pattern consisting of five regular and parallel, black, longitudinal bands along the body, which are frequently expressed as series of interrupted lines or broken up into individual blotches, and a white margin to the soft dorsal, anal, and caudal fins and by the number of vertebrae. Mastacembelus pantherinus, new species, from Lake Indawgyi, Kachin State, in northern Myanmar differs also from its congeners by a unique colour pattern that consists of numerous individual spots or irregular marks, sometimes forming short lines and a whitish belly devoid of any marks.
