The following combination of characters distinguishes it from all known congeners: dorsal fin X, 15; anal-fin rays III, 7; pectoral-fin rays 13 | 13 (13 | 12), all unbranched; principal caudal-fin rays 9 + 8; lateral line complete with 30\u201332 tubed scales; gill rakers 5 + 12; circumpeduncular scales 11\u201312; and absence of antrorse or retrorse spines on ventral margin of preopercle. Coloration in life consists of a white to light pink body with two indistinct rows of irregularly shaped red-orange to yellow-orange patches along the dorsal two-thirds of the body, a golden-yellow opercle and maxilla, an indistinct yellow stripe on the dorsal fin, two yellow spots near the base of the anal fin, and two irregularly shaped yellow-orange spots located on either side of centermost caudal-fin rays. With this publication, the genus <jats:italic>Plectranthias<\/jats:italic> now comprises 67 valid species. This discovery adds to a strong body of research highlighting the novel biodiversity of mesophotic ecosystems, especially in locations like the Indian Ocean, where few prior ichthyological surveys have been conducted.<\/jats:p>","DOI":"10.3897\/zookeys.1223.135292","type":"journal-article","created":{"date-parts":[[2025,1,16]],"date-time":"2025-01-16T12:56:16Z","timestamp":1737032176000},"page":"333-344","source":"Crossref","is-referenced-by-count":1,"title":["Plectranthias raki (Teleostei, Serranidae), a new species of perchlet from mesophotic coral ecosystems of the Maldives"],"prefix":"10.3897","volume":"1223","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8918-1551","authenticated-orcid":true,"given":"Bart","family":"Shepherd","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3143-1474","authenticated-orcid":true,"given":"Hudson T.","family":"Pinheiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Najeeb","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8069-6535","authenticated-orcid":true,"given":"Claudia R.","family":"Rocha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4011-569X","authenticated-orcid":true,"given":"Luiz A.","family":"Rocha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2025,1,16]]},"reference":[{"key":"135292_B1","first-page":"285","article-title":"Pelagic stromateoid fishes (Pisces, Perciformes) of the eastern Pacific: kinds, distributions, and early life histories and observations on five of these from the northwest Atlantic.","volume":"26","author":"Ahlstrom","year":"1976","journal-title":"Bulletin of Marine Science"},{"key":"135292_B2","first-page":"82","article-title":"Plectranthias bennetti, a new species of anthiine fish (Pisces: Serranidae) from the Coral Sea, Australia.","volume":"16","author":"Allen","year":"2015","journal-title":"Journal of the Ocean Science Foundation"},{"key":"135292_B3","doi-asserted-by":"publisher","DOI":"10.70249\/9798893983760"},{"key":"135292_B4","doi-asserted-by":"publisher","DOI":"10.3897\/zookeys.835.27528"},{"key":"135292_B5","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.3785.3.10"},{"key":"135292_B6","first-page":"25","article-title":"Plectranthias normanby, a new species of perchlet from Papua New Guinea, western Pacific (Teleostei: Serranidae).","volume":"20","author":"Fricke","year":"2021","journal-title":"FishTaxa"},{"key":"135292_B7","author":"Fricke","year":"2024"},{"key":"135292_B8","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.4455.3.8"},{"key":"135292_B9","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.4750.4.6"},{"key":"135292_B10","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.4205.4.3"},{"key":"135292_B11","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.4918.1.1"},{"key":"135292_B12","first-page":"3","article-title":"A review of the anthiine fish genus Plectranthias (Perciformes: Serranidae) of the Western Indian Ocean, with description of a new species, and a key to the species.","volume":"10","author":"Heemstra","year":"2008","journal-title":"Smithiana Bulletin"},{"key":"135292_B13","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/bts199"},{"key":"135292_B14","doi-asserted-by":"publisher","DOI":"10.1007\/s10228-021-00842-1"},{"key":"135292_B15","author":"Kuiter","year":"2004","journal-title":"Serranidae & Plesiopidae: A Comprehensive Guide to Basslets, Hamlets, Longfins & relatives."},{"key":"135292_B16","doi-asserted-by":"publisher","DOI":"10.1007\/s00338-019-01825-5"},{"issue":"1","key":"135292_B17","first-page":"101","article-title":"Revision of the genus Plectranthias (Serranidae: Anthiinae) with descriptions of 13 new species.","volume":"16","author":"Randall","year":"1980","journal-title":"Micronesica"},{"key":"135292_B18","author":"Randall","year":"1993"},{"key":"135292_B19","doi-asserted-by":"publisher","DOI":"10.1126\/science.aaq1614"},{"key":"135292_B20","doi-asserted-by":"publisher","DOI":"10.3897\/zookeys.762.24618"},{"key":"135292_B21","doi-asserted-by":"publisher","DOI":"10.5281\/zenodo.3237914"},{"key":"135292_B22","doi-asserted-by":"publisher","DOI":"10.3897\/zookeys.941.50243"},{"key":"135292_B23","doi-asserted-by":"publisher","DOI":"10.3897\/zookeys.1054.64508"},{"key":"135292_B24","first-page":"359","article-title":"Fishes of the Family Anthiidae from the Western Indian Ocean and the Red Sea.
