In contrast, the other species, <jats:italic>L. taprobanes<\/jats:italic> and <jats:italic>L. lithophagus<\/jats:italic>, are only known from nymphs. Here, we describe a new species, <jats:italic>Languidipes janae<\/jats:italic> sp nov, based on male imagos collected from Borneo, Indonesia. This new species is characterized by the presence of ommation on mesonotum, and penis almost completely divided, with sub-quadrate base and a small outer projection basal to the long and slender distal arms. This constitutes the first record of the genus for Borneo. A cladistic analysis of the subfamily Asthenopodinae supports its taxonomic status.<\/jats:p>","DOI":"10.7717\/peerj.17327","type":"journal-article","created":{"date-parts":[[2024,5,3]],"date-time":"2024-05-03T07:07:33Z","timestamp":1714720053000},"page":"e17327","source":"Crossref","is-referenced-by-count":0,"title":["A new species of <i>Languidipes<\/i> Hubbard (Ephemeroptera, Polymitarcyidae) from Borneo"],"prefix":"10.7717","volume":"12","author":[{"given":"Guillermo Eduardo","family":"Hankel","sequence":"first","affiliation":[{"name":"Instituto de Biodiversidad Neotropical (IBN), Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), Facultad de Ciencias Naturales e Instituto Miguel Lillo, Universidad Nacional de Tucum\u00e1n, Yerba Buena, Tucum\u00e1n, Argentina"},{"name":"Instituto de Invertebrados, Fundaci\u00f3n Miguel Lillo, San Miguel de Tucum\u00e1n, Tucum\u00e1n, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Molineri","sequence":"additional","affiliation":[{"name":"Instituto de Biodiversidad Neotropical (IBN), Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), Facultad de Ciencias Naturales e Instituto Miguel Lillo, Universidad Nacional de Tucum\u00e1n, Yerba Buena, Tucum\u00e1n, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4443","published-online":{"date-parts":[[2024,5,3]]},"reference":[{"key":"10.7717\/peerj.17327\/ref-1","doi-asserted-by":"publisher","first-page":"107","DOI":"10.1080\/01650424.2012.713487","article-title":"The adult stage of Languidipes corporaali (Lestage, 1922), new status and the validity of Povilla (Navas) (Ephemeroptera: Polymitarcyidae: Asthenopodinae)","volume":"34","author":"Baumgardner","year":"2012","journal-title":"Aquatic Insects"},{"key":"10.7717\/peerj.17327\/ref-2","doi-asserted-by":"publisher","first-page":"3","DOI":"10.1038\/s41529-022-00216-6","article-title":"Bioerosion of siliceous rocks driven by rock-boring freshwater insects","volume":"6","author":"Bolotov","year":"2022","journal-title":"Npj Materials Degradation"},{"key":"10.7717\/peerj.17327\/ref-3","first-page":"91","article-title":"The Indian Ephemeroptera (mayflies).
