The new species is characterised by having a nearly spherical female, with dimensions of length \u00d7 width = 532.3 (423.8\u2013675.3) \u00d7 295.6 (160.0\u2013381.2) \u03bcm, stylet length of 35.7 (31.1\u201342.1) \u03bcm, protruding vulval lips, a vulval slit measuring 54.2 (47.4\u201358.9) \u03bcm, an area between the vulva and anus that is flat to concave, and a vulva\u2013anus distance 49.3 (41.1\u201357.6) \u03bcm. The male features two lip annules, a stylet length of 31.7 (27.4\u201334.8) \u03bcm and basal knobs that are slightly projecting anteriorly, while lateral field is areolated with three incisures and spicules length of 27.1 (23.7\u201331.0) \u03bcm. The second stage juvenile is characterised by a body length of 506.1 (441.8\u2013564.4) \u03bcm long, two to three lip annules, a stylet length 31.2 (29.7\u201333.2) \u03bcm which is well developed, basal knobs projecting anteriorly, a lateral field that is areolate with three incisures, and a narrow rounded tail measuring 63.2 (54.2\u201371.3) \u03bcm long, with a hyaline region of 35.6 (27.4\u201356.6) \u03bcm long that is longer than the stylet. Based on morphology and morphometrics, the new species is closely related to <jats:italic>C. sinensis<\/jats:italic> and <jats:italic>C. japonicum<\/jats:italic> within the genus <jats:italic>Cryphodera.<\/jats:italic> The phylogenetic trees constructed based on the ITS-rRNA, 28S-rRNA D2\u2013D3 region, and the partial <jats:italic>COI<\/jats:italic> gene sequences indicate that the new species clusters with other <jats:italic>Cryphodera<\/jats:italic> species but maintains in a separated subgroup.
