Significantly, its distinct penes not only validates its independent species status, but also reveals the evolutionary process of the reduction of neoephemerid male genitalia and provides the original clue of the vestigial penes in several other lineages of the order Ephemeroptera as well.\n                  <\/jats:p>","DOI":"10.3897\/bdj.14.e211811","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T08:30:53Z","timestamp":1790584253000},"source":"Crossref","is-referenced-by-count":0,"title":["Reared adults of Potamanthellus unicutibius Nguyen &amp;amp; Bae, 2003 from China (Ephemeroptera, Neoephemeridae)"],"prefix":"10.3897","volume":"14","author":[{"given":"Dewen","family":"Gong","sequence":"first","affiliation":[{"name":"Nanjing Normal University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changfa","family":"Zhou","sequence":"additional","affiliation":[{"name":"Nanjing Normal University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2258","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"key":"211811_B14406760","doi-asserted-by":"publisher","DOI":"10.1076\/aqin.20.1.35.4489"},{"key":"211811_B14406769","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.5636.2.10"},{"key":"211811_B14406778","doi-asserted-by":"publisher","DOI":"10.1163\/22119434-bja10022"},{"issue":"4","key":"211811_B14406913","first-page":"319","article-title":"New Chinese mayflies from Kiangsi province (Ephemeroptera)","volume":"10","author":"Hsu","year":"1936","journal-title":"Peking Natural History Bulletin"},{"issue":"8","key":"211811_B14406922","first-page":"411","article-title":"Badnania nad fauna j\u0119tek (Ephemeroptera) Wielkopolski.
