First Record of Aphelenchoides nonveilleri (Nematoda: Aphelenchoididae) from South Korea

Aphelenchoides nonveilleri $Andr{\acute{a}}ssy$, 1959, belonging to the family Aphelenchoididae Skarbilovich, 1947, is first reported from South Korea. The genus Aphelenchoides Fischer, 1894 includes about 200 species worldwide, but to date only nine Aphelnechoides species have been reported from South Korea. Specimens of A. nonveilleri were collected from the roots and shoot tips of chrysanthemum (Chrysanthemum morifolium Ramat, 1792) from a greenhouse. This species is distinguished from other Aphelenchoides species by its star-shaped mucro on the female tail tip, three lateral incisures, and the length of the post-vulvar uterine sac. Here we provide details of the morphological characters and morpometrics of A. nonveilleri based on optical microscopy.
