In this review, three <jats:italic>Isca<\/jats:italic> species are presented and photographed. Among them, <jats:italic>I. acutata<\/jats:italic><jats:bold>sp. nov.<\/jats:bold> is a new species with an acute male penal apex, a uniform brown abdomen of the imago, and a bilamellate gill VII of the nymph. Another species, <jats:italic>I. fascia<\/jats:italic>, previously reported from Vietnam, is found in China for the first time. The nymphs of <jats:italic>I. fascia<\/jats:italic> exhibit a banded body and a convex apex of the penes. The structure of the third species <jats:italic>I. purpurea<\/jats:italic>, shown graphically, has separated penes and a paler nymphal body than the other two species. The diverse morphology of the penes, wings, venation, and gills show that <jats:italic>Isca<\/jats:italic> has diverse species and evolutionary directions, suggesting that the previous subgeneric classification may not adequately represent some species. Biologically, their nymphs were observed living in tiny pits on substrate surfaces, where their ventral gills may facilitate respiration while they hide.<\/jats:p>","DOI":"10.3897\/zookeys.1234.140905","type":"journal-article","created":{"date-parts":[[2025,4,11]],"date-time":"2025-04-11T11:31:59Z","timestamp":1744371119000},"page":"239-258","source":"Crossref","is-referenced-by-count":1,"title":["Review of the genus Isca (Ephemeroptera, Leptophlebiidae) from China with a new species and a new species record"],"prefix":"10.3897","volume":"1234","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3740-7125","authenticated-orcid":true,"given":"De-Wen","family":"Gong","sequence":"first","affiliation":[{"name":"Nanjing Normal University, Nanjing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8785-5228","authenticated-orcid":true,"given":"Chang-Fa","family":"Zhou","sequence":"additional","affiliation":[{"name":"Nanjing Normal University, Nanjing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2025,4,11]]},"reference":[{"key":"140905_B1","doi-asserted-by":"crossref","DOI":"10.1163\/9789004260887","author":"Bauernfeind","year":"2012","journal-title":"The Mayflies of Europe (Ephemeroptera)."},{"key":"140905_B2","doi-asserted-by":"publisher","DOI":"10.1093\/aesa\/52.1.43"},{"key":"140905_B3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-3113.1951.tb01009.x"},{"key":"140905_B4","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth.4285"},{"key":"140905_B5","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.3760.4.2"},{"key":"140905_B6","first-page":"433","article-title":"Contribution \u00e0 l\u2019\u00e9tude des larves des Eph\u00e9m\u00e9ropt\u00e8res.
