Two populations of were detected in the rhizosphere of sp. and Chinese red pine from Taizhou and Hangzhou, Zhejiang Province, China. Previously, has been reported from China whereas was originally described from India decades ago in the rhizosphere of peach but was never reported thereafter. In this study, both species were characterized morphologically and molecularly coupled with SEM observations. Morphologically, both species have four incisures in the lateral field, vulval present (SEM observations), stylet less than 30 μ m long and cephalic region without submedian lobes. Phylogenetically, both species grouped with paratylenchid species having short stylets. Both species can be differentiated from each other by the shape of lip region (rounded in and narrow truncated in ) and tail terminus (pointed in and a broadly rounded in ) and several morphomemtrical values.The study provided an updated description of and and a first record of from China. In addition, both species are the first paratylenchid species recorded from sp. and , respectively.
