Two new nematode species of the genus <i>Zalonema</i> (Desmodorida, Desmodoridae, Desmodorinae) from mangrove wetlands, China.

ABSTRACT: Two new species of the genus Zalonema Cobb, 1920 were identified during a meiofaunal survey of mangrove sediment in China. Zalonema eurysbucca sp. nov. is characterized by body length 1772-2309 µm, cuticle with transverse annuli; cephalic setae measuring 1-2 µm, and eight subcephalic setae (2-3 µm) arranged in a circle between the cephalic setae and the anterior margin of the amphid; amphideal fovea (4-4.5 turns) located laterally on the main posterior portion of the cephalic capsule; buccal cavity large and cup-shaped, with twelve cheilorhabdia in the vestibule, a cuticularized dorsal tooth, and minute ventral tooth; males possess lateral and ventral alae; spicule length (as arc) about 1.13-1.34 times the anal body diameter (abd); a small cup-shaped preanal supplement
