摘要：

A new nematode species, Phasmarhabditis meridionalis sp. n., was isolated from the land snail Quantula striata in Cat Tien Natural Park in southern Vietnam. The nematode is characterised by a wide stoma in adult nematodes, a cupola-shaped female tail with a filamentous spike, long, thin, slightly projecting phasmids in females and males with the longest spicules (76 (71-83) mu m) within the genus featuring hook-like distal tips. Dauer larvae of P. meridionalis sp. n. are 839 (770-912) mu m long; a lateral field in adults is a simple narrow band with marginal, slightly elevated ridges and, in dauer larvae, expressed as a central band flanked by 4 ridges (3 incisions) at each side. The molecular analysis based on partial sequences of LSU, SSU and ITS rDNA regions has been performed. Both morphologically and genetically, the new species is close to another Asian species, P. huizhouensis Huang, Ye, Ren & Zhao (2015).
