New Fish Species Identification Using XPERT 80 X-ray Imaging System
Type locality and species identity of Pareuchiloglanis sinensis (Hora & Silas), with a description of a new species of the genus from the upper Yangtze River basin in Southern China
The XPERT 80 from KUBTEC was employed in a scientific study to explore the locality and identity of Pareuchiloglanis sinensis using X-ray imaging technology.
The genus Pareuchiloglanis, distributed in the Salween, Mekong, Red, Pearl, and Yangtze River basins in China, Laos, Myanmar, and Vietnam consists of 20 valid species and five uncertain species. Herein, we provided a taxonomic revision to Pareuchiloglanis occurring in the Yangtze River. According to the results of a morphological comparison, the type locality of Pareuchiloglanis sinensis was updated to the Nanpan-jiang (the upper Pearl River) basin; five species were identified in Pareuchiloglanis from the Yangtze River basin. Specimens formerly identified as P. sinensis from this basin were described as a new species, P. chui sp. Moreover, P. tianquanensis was synonymized with P. sichuanensis. We provided a key to these two species and three others (P. anteanalis, P. hupingshanensis and P. robusta) from the Yangtze River basin, including information about their geographical distribution. These findings provide insight for future studies on the evolution, distribution, and taxonomy of this genus.
