New morphological information is provided for some structures of this nematode species, such as a flattened cephalic extremity, presence of two dorsal cephalic papillae, female tail with a constriction at its tip, \u201cs\u201d shaped vagina, spicules characteristic of the carinii species group and microfilaria tail constricted at the tip. This nematode was found parasitizing the thoracic cavity with a prevalence of 10% (2\/20), mean intensity of 4 (6\/2), mean abundance of 0.4 (8\/20) and range of infection of 2-6 specimens per host, in southern Brazil. This occurrence of L. silvai in A. montensis is a new geographical record for southern Brazil, in the Upper Paran\u00e1 Atlantic Forest ecoregion of the northwestern region of Rio Grande do Sul, which is part of the Atlantic Forest biome.<\/jats:p>","DOI":"10.1590\/s1984-29612017060","type":"journal-article","created":{"date-parts":[[2017,10,21]],"date-time":"2017-10-21T22:29:40Z","timestamp":1508624980000},"page":"433-438","source":"Crossref","is-referenced-by-count":2,"title":["Litomosoides silvai (Nematoda: Onchocercidae) parasitizing Akodon montensis (Rodentia: Cricetidae) in the southern region of Brazil"],"prefix":"10.1590","volume":"26","author":[{"given":"Lucas Trevisan","family":"Gressler","sequence":"first","affiliation":[{"name":"Universidade Federal de Santa Maria,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felipe da Silva","family":"Krawczak","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil;
