The evolutionary relationships among these taxa are still poorly understood, and molecular analyses are restricted to mitochondrial genes, which have not been conclusive. We compiled both mitochondrial and nuclear genes in order to study the phylogenetic position of <jats:italic>Microphilypnus<\/jats:italic> and the evolutionary history and relationships of eleotrids. We propose that Microphilypnus and Leptophilypnus (a non-miniature genus) are not sister groups as suggested by previous studies, but rather separate lineages that arose in the early Eocene, with <jats:italic>Leptophilypnus<\/jats:italic> recovered as a sister group to the other analyzed eleotrids. In fact, <jats:italic>Microphilypnus<\/jats:italic> is currently associated with the Neotropical clade <jats:italic>Guavina\/Dormitator\/Gobiomorus<\/jats:italic>. We also identified a well-supported clade that indicated <jats:italic>Gobiomorus<\/jats:italic> and <jats:italic>Hemieleotris<\/jats:italic> as paraphyletic groups, besides a close relationship among <jats:italic>Calumia godeffroyi<\/jats:italic>, <jats:italic>Bunaka gyrinoides, Eleotris<\/jats:italic> and <jats:italic>Erotelis<\/jats:italic> species. This is the first comprehensive report about the evolutionary relationships in members of the family Eleotridae, including multiloci and multispecies approaches. Therefore, we provided new insights about the phylogenetic position of some taxa absent in previous studies, such as the miniature genus <jats:italic>Microphilypnus<\/jats:italic> and a recently described species of <jats:italic>Eleotris<\/jats:italic> from South America.<\/jats:p>","DOI":"10.21203\/rs.3.rs-1413222\/v1","type":"posted-content","created":{"date-parts":[[2022,4,1]],"date-time":"2022-04-01T20:12:13Z","timestamp":1648843933000},"source":"Crossref","is-referenced-by-count":0,"title":["Phylogenetic relationships of sleeper gobies (Eleotridae: Gobiiformes: Gobioidei), with comments on the position of the miniature genus Microphilypnus"],"prefix":"10.21203","author":[{"given":"Isadola Eus\u00e9bio","family":"Macate","sequence":"first","affiliation":[{"name":"Universidade Federal do Par\u00e1"}]},{"given":"Adam","family":"Bessa-Silva","sequence":"additional","affiliation":[{"name":"Universidade Federal do Par\u00e1"}]},{"given":"Rodrigo","family":"Caires","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}]},{"given":"Marcelo","family":"Vallinoto","sequence":"additional","affiliation":[{"name":"Universidade Federal do Par\u00e1"}]},{"given":"Tommaso","family":"Giarrizzo","sequence":"additional","affiliation":[{"name":"Universidade Federal do Par\u00e1"}]},{"given":"Arturo","family":"Angulo","sequence":"additional","affiliation":[{"name":"Universidad de Costa Rica, San Pedro de Montes de Oca"}]},{"given":"Gorgonio","family":"Ruiz-Campos","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Baja California, Baja California"}]},{"given":"Iracilda","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Universidade Federal do Par\u00e1"}]},{"given":"Auryc\u00e9ia","family":"Guimar\u00e3es-Costa","sequence":"additional","affiliation":[{"name":"Universidade Federal do Par\u00e1"}]}],"member":"8761","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.researchsquare.com\/article\/rs-1413222\/v1","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.researchsquare.com\/article\/rs-1413222\/v1.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,1]],"date-time":"2022-04-01T20:12:15Z","timestamp":1648843935000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.researchsquare.com\/article\/rs-1413222\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,4,1]]},"references-count":0,"URL":"https:\/\/doi.org\/10.21203\/rs.3.rs-1413222\/v1","relation":{},"subject":[],"published":{"date-parts":[[2022,4,1]]},"subtype":"preprint"}}
