A new cyst-forming nematode, Cactodera tianzhuensis n. sp. (Nematoda:Heteroderinae) from Polygonum viviparum in China with a key to the Genus Cactodera
A new cyst-forming nematode, Cactodera tianzhuensis n. sp. was isolated from the rhizosphere soil of Polygonum viviparum L. in Tianzhu county, China. Morphologically, the new species is characterized by lemon-shaped or rounded cysts that have protruding necks and vulval cones. The vulval cone of the...

A new cyst-forming nematode, Cactodera tianzhuensis n. sp. was isolated from the rhizosphere soil of Polygonum viviparum L. in Tianzhu county, China.

The vulval cone of the new species appeared to be circumfenestrate without bullae and underbridge, vulval denticle present and anus distinct. Second-stage juveniles are vermiform, stylet well-developed with the rounded stylet knobs to slightly concave anteriorly. Lateral field with four incisures.
