Stenocypris major major (Baird, 1859) and Stenocypris major sketi Petkovski & Meisch, 1996 were encountered in the Eastern part of Thailand. These two taxa are thus re-described based on Thai materials. The taxonomic position of S. major sketi is revised and placed as a separated species due to the distinct features in the valves and the soft parts morphology, especially in the presence of the postero-dorsal expansion on both valves, the different patterns of the posterior inner lamella margins and the caudal ramus morphology. Therefore, S. sketi Petkovski & Meisch, 1996 is erected for S. major sketi. The occurrence of S. sketi in the present contribution is the first report in Thailand and Southeast Asia. This taxon is thus far endemic to the Oriental region. The selected diagnostic characters of the genus Stenocypris are also briefly discussed.
