The new species was compared morphologically with the 29 known species that parasitize rodents distributed in 12 families in North and South America; T. guanacastei n. sp. it is characterized by the following set of traits: presence of a spicular tube (measuring 0.72-0.99); thick proximal cloacal tube and a short distal cloacal tube with a total length of 0.72-1.36; eggs 0.03-0.05 long and a semi-protrusible vulva. The new species represents the first one described in the genus in Costa Rica and the fifth one described in the Americas that parasite Heteromyidae.<\/jats:p>","DOI":"10.1590\/s1984-29612020028","type":"journal-article","created":{"date-parts":[[2020,6,27]],"date-time":"2020-06-27T08:00:46Z","timestamp":1593244846000},"source":"Crossref","is-referenced-by-count":2,"title":["New species of Trichuris (Nematoda: Trichuridae) parasitizing Heteromys salvini (Rodentia: Heteromyidae) from Costa Rica, with a key to Trichuris species described from Heteromyidae"],"prefix":"10.1590","volume":"29","author":[{"given":"Jorge","family":"Falc\u00f3n-Ordaz","sequence":"first","affiliation":[{"name":"Universidad Aut\u00f3noma del Estado de Hidalgo,  M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ren\u00e9 Josu\u00e9","family":"Monzalvo-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma del Estado de Hidalgo,  M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7529-1514","authenticated-orcid":false,"given":"Luis","family":"Garc\u00eda-Prieto","sequence":"additional","affiliation":[{"name":"Universidad Nacional Aut\u00f3noma de M\u00e9xico,  Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2020]]},"reference":[{"issue":"2","key":"ref1","doi-asserted-by":"crossref","first-page":"366","DOI":"10.1644\/BER-120.1","article-title":"Phylogenetics of the new world rodent Family Heteromyidae","volume":"86","author":"Alexander LF","year":"2005","journal-title":"J Mammal"},{"issue":"6","key":"ref2","doi-asserted-by":"crossref","first-page":"1061","DOI":"10.2307\/3279376","article-title":"Trichuris bradleyi sp. n., a whipworm from Octodon degus in Chile","volume":"61","author":"Babero BB","year":"1975","journal-title":"J Parasitol"},{"issue":"2","key":"ref3","doi-asserted-by":"crossref","first-page":"232","DOI":"10.2307\/3225071","article-title":"A new species of whipworm from the rodent Akodon longipilis in Chile","volume":"95","author":"Babero BB","year":"1976","journal-title":"Trans Am Microsc Soc"},{"issue":"2","key":"ref4","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1590\/S0074-02761990000200012","article-title":"A new species of whipworm from a South American hystricomorph rodent","volume":"85","author":"Babero BB","year":"1990","journal-title":"Mem Inst Oswaldo Cruz"},{"issue":"2","key":"ref5","doi-asserted-by":"crossref","first-page":"190","DOI":"10.2307\/3226320","article-title":"The helminth fauna of Chile.
