74F7A782BFA25E649D6B19044B4217B1.taxon	etymology	Etymology. This newly discovered species exhibits morphological similarities with Cuneopsis celtiformis, which led us to incorporate this resemblance into its naming. Specifically, we used the word ‘ celti’ (derived from ‘ celtiformis ’) with the middle ‘ o’ connected to the Latinized word ‘ similis’ (similar) to name this new species. For the common name, we recommend “ Similar Wedged Mussel ” (English) and “ Jin Si Xie Bang ” (近似楔蚌) (Chinese).	en	Hou, Kaiyu, Wang, Xianan, Nan, Fang, Wu, Ruiwen (2025): Underestimated diversity: A new species of the genus Cuneopsis (Bivalvia, Unionidae, Unioninae) from Henan, China.
