title: Deladenus valveus n. sp. (Nematoda: Neotylenchidae) in Dunnage Wood from South Korea Intercepted in Ningbo, China.
abstract: Deladenus valveus n. sp., isolated from packaging wood originated from South Korea and intercepted in Ningbo, P.R. China, is described and illustrated. Both mycetophagous and infective forms were recovered and are described. The new species D. valveus n. sp. resembles other Deladenus species in which the excretory pore is situated anterior to the hemizonid: in mycetophagous females, the excretory pore is 59 to 74 μm from the anterior end and 37 to 54 μm anterior to the hemizonid. The new species is characterized by the presence of a distinct valve at the esophago-intestinal junction in mycetophagous females and by a degenerate esophagus in mycetophagous males, both of which characters are reported for the first time in a species of Deladenus.
