| Abstract |
A new species of free-living marine nematode of the genus Daptonema Cobb, 1920 is described from the sublittoral sediment of the Jiaozhou Bay, Qingdao. Daptonema parabreviseta sp. nov. is characterized by having narrowed anterior end; small funnel-shaped buccal cavity; short cephalic setae; spicules with bulbiform proximal end and pointed distal end; gubercunalum tubular shape with a blunt dorsal apophysis. The female genital system presents a spacious postvulval sac. The new species closely resembles Daptonema brevisetosum Thanh & Gagarin, 2009. However, it differs from Daptonema brevisetosum by having relatively narrowed head (10 μm vs 20 μm); spicules with bulbiform proximal end and pointed distal end, not bifurcated at distal end. Female genital system with a spacious postvulval sac (vs absent). |
