Eleven species have been characterised, with\n                    <jats:italic>C. felineus<\/jats:italic>\n                    and\n                    <jats:italic>C. subaequalis<\/jats:italic>\n                    being reported in jaguarundis,\n                    <jats:italic>Herpailurus yagouaroundi<\/jats:italic>\n                    , from Brazil. Herein, we described spirocercid reddish worms collected from three jaguarundis from Costa Rica by using hierarchical clustering and dendrogram plots of morphological characters reported from our specimens and compared to other\n                    <jats:italic>Cylicospirura<\/jats:italic>\n                    spp., histopathological observations of associated lesions, and phylogenetic analyses of both mitochondrial and ribosomal loci. Nematodes were found within stomach nodules located in the submucosa causing a pyogranulomatous, multifocal, nodular, and sclerosing gastritis. In addition, the collected worms differed from their congeners by having a longer body and smaller muscular and glandular oesophagus, subsequently showing lower total oesophagus to body length percentage and ratio of glandular to muscular oesophagus. Cytochrome oxidase subunit 1 and internal transcribed spacer 1 analyses revealed that worms were 8.33 to 8.66% different from\n                    <jats:italic>C. felineus, C. subaequalis<\/jats:italic>\n                    , or\n                    <jats:italic>C. petrowi<\/jats:italic>\n                    and 15.2 to 15.4% different from\n                    <jats:italic>C. petrowi<\/jats:italic>\n                    , respectively.
