It is distinguished from all known species within the subfamily Acrossocheilinae by having a combination of the following characteristics: a crescent horny sheath on the lower jaw, a less prominent lower lip limited to the corners of the mouth, a serrated posterior edge of the last simple dorsal-ray, 47\u201350 lateral-line scales, 9 scales above the lateral line, 16\u201318 circumpeduncular scales, and 16\u201318 pre-dorsal midline scales. The molecular phylogeny revealed that H. zhangbuensis sp. nov. was a sister taxon to Hongiastomata argentatum, with a genetic distance ranging from 10.49% to 10.68%. Together, they formed a lineage at the base of the Acrossocheilinae clade. Furthermore, the interspecific genetic distances between the new species and those of Onychostoma sensu lato ranged from 9.9 to 13.4%, indicating significant genetic divergence between this new species and all known species within Onychostoma sensu lato. Therefore, both morphological and molecular data support the recognition of this species as new.<\/jats:p>","DOI":"10.3390\/ani15172563","type":"journal-article","created":{"date-parts":[[2025,9,1]],"date-time":"2025-09-01T14:02:46Z","timestamp":1756735366000},"page":"2563","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hongiastoma zhangbuensis, a New Species of the Subfamily Acrossocheilinae (Teleostei: Cyprinidae) from South China"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9855-6503","authenticated-orcid":false,"given":"Lan-Ping","family":"Zheng","sequence":"first","affiliation":[{"name":"College of Traditional Chinese Medicine, Yunnan University of Chinese Medicine, Kunming 650500, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4324-1926","authenticated-orcid":false,"given":"Wei-Tao","family":"Chen","sequence":"additional","affiliation":[{"name":"Pearl River Fisheries Research Institute, Chinese Academy of Fishery Sciences, Guangzhou 510380, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,31]]},"reference":[{"unstructured":"Eschmeyer, W.N.
