Abstract
The species of the Macrognathus aculeatus group from Myanmar are reviewed and three new species are described. Macrognathus dorsiocellatus, new species, previously identified as M. aral, is distinguished by rostral tooth plates 19-23, dorsal fin spines 14-22, 7-11 small ocelli along soft dorsal fin, with ventrally open, incomplete white rim; M. obscurus, new species, is distinguished by rostral tooth plates 8-10, dorsal fin spines 20-22, ocelli along dorsal fin developed as small irregularly arranged dark spots or absent, M. pavo, new species, is distinguished by the presence of only 4-6 dorsal-fin spines, only 6-8 rostral tooth plates and details of the colour pattern. In addition, M. lineatomaculatus, new species, is described from India and Nepal and it is distinguished by rostral tooth plates 15-17, dorsal fin spines 19-22, and large black blotches along dorsal fin. The systematic position of M. caudiocellatus is reviewed and the species is retransferred to Mastacembelus.
