In the present study, the detailed morphology of this poorly known species was studied using light and scanning electron microscopy based on the newly material collected from Hoplobatrachus chinensis<\/jats:italic> (Osbeck) (Amphibia: Anura) in China. We found that the relative length of intestinal caecum in our male specimens (representing 68.4\u201371.1% of oesophageal length) is slighter longer than the previously reported data (not over 60.0% of oesophageal length). Our SEM observations also revealed the presence of ca. 64\u201376 small conical denticles on each lip. In addition, Angusticaecum wuyiensis<\/jats:italic> Wang, 1981, collected from Rana schmackeri<\/jats:italic> Boettger (Amphibia: Anura) from Wuyi Mountain in Fujian Province, China was considered as a new synonym of S<\/jats:italic>. numidica<\/jats:italic>. The ITS and cox<\/jats:italic>1 sequences of S<\/jats:italic>. numidica<\/jats:italic> were also sequenced for the first time and there is no nucleotide variability detected in both regions. The present supplementary morphological and molecular data (especially the ITS and cox<\/jats:italic>1 sequences) obtained herein is extremely important and useful to determine the morphological variability, population genetics and phylogenetic position of S<\/jats:italic>. numidica<\/jats:italic> in the future.<\/jats:p>","DOI":"10.1515\/ap-2018-0017","type":"journal-article","created":{"date-parts":[[2018,1,19]],"date-time":"2018-01-19T22:15:48Z","timestamp":1516400148000},"page":"154-159","source":"Crossref","is-referenced-by-count":7,"title":["Morphological and molecular characterization of Seuratascaris numidica (Seurat, 1917) (Ascaridida: Ascarididae)"],"prefix":"10.1007","volume":"63","author":[{"given":"Hui-Xia","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu-Ping","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","reference":[{"key":"ref31","doi-asserted-by":"crossref","first-page":"292","DOI":"10.1007\/s12639-016-0751-z","article-title":"First report of Seuratascaris numidica Seurat, 1917 (Nematoda: Ascarididae) and other helminths from amphibians of West Bengal, India","volume":"41","year":"2017","journal-title":"Journal of Parasitic Diseases"},{"key":"ref111","doi-asserted-by":"crossref","first-page":"292","DOI":"10.1007\/s12639-016-0751-z","article-title":"First report of Seuratascaris numidica Seurat, 1917 (Nematoda: Ascarididae) and other helminths from amphibians of West Bengal, India","volume":"41","year":"2017","journal-title":"Journal of Parasitic Diseases"},{"key":"ref101","first-page":"404","article-title":"Ribosomal and mitochondrial DNA analyses of Xiphinema americanum-group populations","volume":"38","year":"2006","journal-title":"Journal of Nematology"},{"key":"ref41","doi-asserted-by":"crossref","first-page":"231","DOI":"10.1051\/parasite\/1985603231","article-title":"Ascaridoid nematodes of amphibians and reptiles: Seuratascaris n. g","volume":"60","year":"1985","journal-title":"Annales de Parasitologie Humaine et Compar\u00e9e"},{"key":"ref121","doi-asserted-by":"crossref","first-page":"231","DOI":"10.1051\/parasite\/1985603231","article-title":"Ascaridoid nematodes of amphibians and reptiles: Seuratascaris n. g","volume":"60","year":"1985","journal-title":"Annales de Parasitologie Humaine et Compar\u00e9e"},{"key":"ref81","doi-asserted-by":"crossref","first-page":"342","DOI":"10.1645\/0022-3395(2003)089[0342:ITNSNO]2.0.CO;2","article-title":"Icosiella turgeocauda n. sp.
