Three new species of the genus Pangio from Myanmar and one new species from India are described. Pangio elongata, new species, from streams in the Tanintharyi division of southern Myanmar is distinguished by the number of abdominal vertebrae. Pangio signicauda, new species, and P. lumbriciformis, new species, both from the Ayeyarwaddy drainage in northern Myanmar differ from their congeners by a unique colour pattern and total vertebral count. The status of P. fusca is clarified and we recognize it as a distinct species differing from P. pangia, with which it was confused previously, by the lack of the pelvic girdle and fins. Pangio apoda, new species, from the Tista drainage in India, also characterized by the lack of the pelvic girdle and fins, differs from P. fusca by fewer abdominal vertebrae, a further anteriorly placed dorsal fin, and the absence of a nasal barbel.
