Adult females were later collected from various garden plants while depositing eggs. These mermithid specimens were identified morphologically as<jats:italic>Mermis nigrescens<\/jats:italic>Dujardin, 1842. A genetic distance of 0.7% between these specimens and a<jats:italic>M. nigrescens<\/jats:italic>isolate from Canada (18S rRNA gene), suggests that they have diverged genetically, but there are currently no available comparable sequences for the European<jats:italic>M. nigrescens<\/jats:italic>. Two additional nuclear fragments were also amplified, the 28S rRNA and the ribosomal DNA first internal transcribed spacer (ITS1), providing a basis for future studies. Bearing in mind the morphological similarity with other reported<jats:italic>M. nigrescens<\/jats:italic>and the lack of sequence data from other parts of the world, we retain the name<jats:italic>M.<\/jats:italic><jats:italic>nigrescens,<\/jats:italic>and suggest that the species may be found to represent a complex of cryptic species when more worldwide data are available. Herein, we present a brief description of the post-parasitic worms and adult females, along with an inferred phylogeny using 18S rRNA gene sequences.<\/jats:p>","DOI":"10.1017\/s0022149x14000017","type":"journal-article","created":{"date-parts":[[2014,2,6]],"date-time":"2014-02-06T15:56:53Z","timestamp":1391702213000},"page":"267-276","source":"Crossref","is-referenced-by-count":19,"title":["Morphological and molecular characterization of<i>Mermis<\/i><i>nigrescens<\/i>Dujardin, (Nematoda: Mermithidae) parasitizing the introduced European earwig (Dermaptera: Forficulidae) in New Zealand"],"prefix":"10.1017","volume":"89","author":[{"given":"B.","family":"Presswell","sequence":"first","affiliation":[]},{"given":"S.","family":"Evans","sequence":"additional","affiliation":[]},{"given":"R.","family":"Poulin","sequence":"additional","affiliation":[]},{"given":"F.","family":"Jorge","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2014,2,6]]},"reference":[{"key":"S0022149X14000017_ref49","doi-asserted-by":"publisher","DOI":"10.1016\/j.jip.2008.04.001"},{"key":"S0022149X14000017_ref8","doi-asserted-by":"publisher","DOI":"10.1080\/03014223.2005.9517786"},{"key":"S0022149X14000017_ref39","first-page":"395","article-title":"Austromermis n. gen. and Blepharomermis n. gen.
