| Abstract | The genus Stenostomum contains small turbellaria that are widely distributed in freshwater environments worldwide.However, there are only rare reports or studies of this genus from Thailand. Therefore, the objective of this study was toreport S. cf. leucops in Thailand collected from Pathum Thani Province. The worm morphology and surface topographyusing scanning electron microscopy were determined. Moreover, the phylogenetic tree of S. cf. leucops was analysed with17 flatworms based on the 18S ribosomal DNA sequences. The phylogenetic relationship shared a common ancestry ofCatenulida species, and S. cf. leucops displayed a monophyletic pattern within Stenostomum spp. The results of the morphologicaland molecular data are discussed. These results may increase the knowledge of freshwater microturbellarians inThailand. |
