Stenocypris major major（Baird，1859）和Stenocypris major sketi Pctkovski & Meisch，1996在泰国东部发现。这两个分类群弧因此重新描述泰国材料的基础上。在分类学上的地位。主要sketi是修订和放置作为一个单独的物种，由于不同的特点，在阀门和软部形态，特别是在存在的后背扩张的两个阀门，不同模式的后内板边缘和尾支形态。因此，S. sketi Pctkovski & Meisel '，：1996 is established for S.斯凯蒂少校。S.本贡献中的sketi是泰国和东南亚的第一份报告。这分类群迄今为止是东方地区特有的。文中还对狭鲤属的特征进行了简要的讨论。
Stenocypris major major (Baird, 1859) and Stenocypris major sketi Pctkovski & Meisch, 1996 were encountered in the Eastern part of Thailand. These two taxa arc 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 Pctkovski & Meisel', :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.
