The LSU–D2D3 segment and the ITS–rDNA region of this species were amplified and sequenced. The morphological characters and molecular phylogenetic analyses confirmed that this is a new species of the genus Pratylenchus in Vietnam.

Abstract Pseudacrobeles (Pseudacrobeles) curvatus sp. n. was collected from potato fields in Gyeongsangnam-do, South Korea. The new species shares morphological characters typical of the genus Pseudacrobeles, including three lateral incisures that fade posteriorly near the phasmid openings. The new species differs from other Pseudacrobeles species by its smaller body size and a comparatively shorter corpus relative to the isthmus length. In this study, we provide a comparison of morphometrics

Based on its membrane-like cheilostomatal plates, the new species is close in form to two elegans group species, P. elegans and P. bucculentus; these three species share this unique morphological character as well as a similar arrangement of genital papillae, i.e., the second pair of genital papillae is oriented laterally (v2d), and the second to fourth pairs (v2d, v3, and v4) are close to each other (Kanzaki et al., 2012, 2013).

Due to the presence of a relatively long body, short PUS, shape of posterior body and a non-branching oviduct to form uterine diverticulum, the new species P. composticola n. sp. is closely related to five known species in the genus: P. asymmetrica, P. balochistanica, P. densa, P. iranica and P. niger.
Compared to Paurodontella asymmetrica, the new species has a shorter stylet, 8 to 9 vs 13 to 14 μ m, a longer body length, 803 to 1,053 vs 330 to 380 μ m, a greater a-ratio, 18.6 to 31.5 vs 16

A new species, Oscheius microvilli n. sp., was found on Chongming Island (Shanghai, China). The new species is morphologically similar to the type strain of Oscheius myriophilus, but can be distinguished from it and other species of Oscheius on the basis of unique morphological characteristics of the bursa as well as male papillae. In this new species, the male bursal papillar formula is 2, 1, 3, 3 with everted tips in the first, fifth, and seventh pairs. The bursal rim is jagged
