Abstract

Pratylenchus loosi Loof, 1960 is recorded for the first time from Korea. The nematode was isolated from the roots of tea (Thea sinensis L.) and soil around the roots from Yeongam-gun, Jeo-llanam-do and Namjeju-gun, Jeju-do, Korea. This species has two lip annuli. The female is 433-646 $\mu\textrm{m}$ long: a= 29.1-37.5, b = 5.1-6.4, c = 15.0-21.3, vulva(%) = 73.0-85.4. The male body length is 408-512$\mu\textrm{m}$ long: a=36.1-40.0, b=4.8-6.7, c =17.0-19.0, and spicule = 14.1-18.0 $\mu\textrm{m}$. The stylet is 11.6-18.0 $\mu\textrm{m}$ long and the number of incisures is four. The shape of spermatheca filled with sperm is broadly rounded, oval and quadrangular The shape of tail is narrowly round to subacute.
