In September 2019, during surveys of the parasites in 12 specimens of L. fasciatus from the lower Jari River basin, in Amap\u00e1 State, Brazil, one specimen of L. guianensis was found in the tongue of one host. The prevalence of L. guianensis was 8.3%, and it was observed that this parasite has a geographic distribution restricted to South America, parasitizing fish species from Guyana and Brazil. This study contributed to the first report on the occurrence of L. guianensis for L. fasciatus in Brazil. In addition, increased the knowledge on the geographic distribution of this parasite with morphometric data, which are scarce for this Cymothoidae.<\/jats:p>","DOI":"10.1590\/s1984-29612020106","type":"journal-article","created":{"date-parts":[[2020,12,6]],"date-time":"2020-12-06T22:20:13Z","timestamp":1607293213000},"source":"Crossref","is-referenced-by-count":1,"title":["First report of Livoneca guianensis (Isopoda: Cymothoidae) in Leporinus fasciatus (Pisces: Anostomidae) in Brazil"],"prefix":"10.1590","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4421-9608","authenticated-orcid":false,"given":"Marcos Sidney Brito","family":"Oliveira","sequence":"first","affiliation":[{"name":"Universidade Federal do Amap\u00e1,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8376-1846","authenticated-orcid":false,"given":"Marcos","family":"Tavares-Dias","sequence":"additional","affiliation":[{"name":"Universidade Federal do Amap\u00e1,  Brasil; Embrapa Amap\u00e1,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2020]]},"reference":[{"issue":"6","key":"ref1","doi-asserted-by":"crossref","first-page":"497","DOI":"10.1086\/286136","article-title":"Parasite abundance, body size, life histories, and the energetic equivalence rule","volume":"151","author":"Arneberg P","year":"1998","journal-title":"Am Nat"},{"issue":"3","key":"ref2","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1651\/C-2573.1","article-title":"Life history of Glossobius hemiramphi (Isopoda: Cymothoidae): development, reproduction, and symbiosis with its host Hemiramphus brasiliensis (Pisces: Hemiramphidae)","volume":"26","author":"Bakenhaster MD","year":"2006","journal-title":"J Crustac Biol"},{"key":"ref3","series-title":"Cymothoidae Leach, 1818","author":"Boyko CB","year":"2008"},{"issue":"3","key":"ref4","doi-asserted-by":"crossref","first-page":"247","DOI":"10.3853\/j.0067-1975.42.1990.118","article-title":"The genera Catoessa, Elthusa, Enispa, Ichthyoxenus, Idusa, Livoneca and Norileca n. gen.
