Abstract excerpt

The loach genus Triplophysa, endemic to the Qinghai-Tibet Plateau, presents persistent taxonomic challenges due to high morphological similarity among species. This study presents the first ultrastructural morphometric data for spermatozoa of Triplophysa strauchii and Triplophysa microphthalma. Mitochondrial COI gene sequences indicated a Kimura 2-parameter (K2P) genetic distance of 5.6% between the studied...
