SEM images are provided for the first time for the species. It is also first shown that H. rigidus presents ridged-shelled eggs. A differential diagnosis is provided. H. rigidus can be differentiated from the rest of the species of this genus by having a short, non inflated first cephalic annule; spines that surpass the level of the oesophagus, an absence of lateral alae, ridged-shelled eggs and its length of the body and tail. The material from the present study differs from a previous redescription by Christie (1934) by its shorter body (2.125\u20132.950 vs. 2.130\u20134.200), first cephalic annule (0.003\u20130.005 vs. 0.012) and oesophagus (0.350\u20130.430 vs. 0.650\u20130.670).\u00a0<\/jats:p>","DOI":"10.11646\/zootaxa.3941.1.8","type":"journal-article","created":{"date-parts":[[2015,3,30]],"date-time":"2015-03-30T00:09:47Z","timestamp":1427674187000},"source":"Crossref","is-referenced-by-count":1,"title":["Redescription of the females of Hystrignathus rigidus Leidy, 1850 (Nematoda: Hystrignathidae), parasites of Odontotaenius disjunctus (Coleoptera: Passalidae) from eastern USA"],"prefix":"10.11646","volume":"3941","author":[{"given":"JANS","family":"MORFFE","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"NAYLA","family":"GARC\u00cdA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ANDREW K.","family":"DAVIS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4913","published-online":{"date-parts":[[2015,3,30]]},"container-title":["Zootaxa"],"original-title":[],"link":[{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.3941.1.8\/37330","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.3941.1.8\/37330","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,3,18]],"date-time":"2024-03-18T01:04:41Z","timestamp":1710723881000},"score":1,"resource":{"primary":{"URL":"https:\/\/mapress.com\/zt\/article\/view\/zootaxa.3941.1.8"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,3,30]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2015,3,30]]}},"URL":"https:\/\/doi.org\/10.11646\/zootaxa.3941.1.8","relation":{},"ISSN":["1175-5334","1175-5326"],"issn-type":[{"value":"1175-5334","type":"electronic"},{"value":"1175-5326","type":"print"}],"subject":[],"published":{"date-parts":[[2015,3,30]]}}}
