Pratylenchus parazeae Wang, Zhao, Ye & Liao. 2015

Morphology and Anatomy:

An apparently monsexual species, males not found and spematheca devoid of sperm.
Anterior en-face view smooth with three lip annuli
Stylet with anteriorly rounded to indented knobs.
Lateral field of four lines with areolated outer bands at vulval region.
V= 68.9â€“74.9 %,
Spermatheca small and oval, devoid of sperm.
Tail subhemispherical tail, usually with smooth terminus but sometimes a dorsally indented terminus.
Phylogenetic trees inferred from BI analysis based on SSU, LSU D2D3 and ITS revealed that P. parazeae can be distinguished from all described root-lesion nematodes, especially from the most closely related species P. zeae
