Morphologically, it displays a recognizable morphological pattern characterized by, among other features, the incurved nature of its odontostyle aperture, presence of perioral liplets or lobes, lip region 24\u201331 \u03bcm wide, odontostyle 21\u201325 \u03bcm long and comparatively anterior location of S<jats:sub>2<\/jats:sub>N pharyngeal gland nuclei. Nevertheless, variations in some morphological traits (vagina shape and tail shape) and in several morphometrics (body length, uterus length, vulva position, tail length and spicule length) are also noted. Sequences of D2\u2013D3 domains of the 28S rDNA, 18S rDNA and COI mtDNA were obtained from several Iberian populations. Their analyses, in particular those from D2\u2013D3 sequences, revealed the existence of a highly supported clade ((<jats:italic>Epacrolaimus<\/jats:italic>+<jats:italic>Sectonema<\/jats:italic>) +<jats:italic>Metaporcelaimus<\/jats:italic>), with a closer relationship between<jats:italic>Epacrolaimus<\/jats:italic>and Palaearctic populations of<jats:italic>Sectonema<\/jats:italic>, whereas the remaining aporcelaimid genera occupied placements in other clades. These results are discussed, with especial emphasis on the intricate separation of<jats:italic>Epacrolaimus<\/jats:italic>and<jats:italic>Sectonema<\/jats:italic>, which display significantly different protruding stomatal structure in spite of their close evolutionary relationship as derived from molecular trees.<\/jats:p>","DOI":"10.1017\/s0022149x2200058x","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T10:40:16Z","timestamp":1664793616000},"source":"Crossref","is-referenced-by-count":1,"title":["On the identity of the genus<i>Epacrolaimus<\/i>Andr\u00e1ssy, 2000 (Nematoda, Dorylaimida), with new insights into its phylogeny"],"prefix":"10.1017","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1125-5490","authenticated-orcid":false,"given":"R.","family":"Pe\u00f1a-Santiago","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0256-876X","authenticated-orcid":false,"given":"P.","family":"Castillo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2022,10,3]]},"reference":[{"key":"S0022149X2200058X_ref20","doi-asserted-by":"publisher","DOI":"10.1163\/156854199508559"},{"key":"S0022149X2200058X_ref29","first-page":"23","article-title":"Die Seen im Aela- und Tinzenhorngebiet II [The lakes in the Aela and Tinzenhorn area II]","volume":"63","author":"Kreis","year":"1924","journal-title":"Nematodes.
