Abstract
|
|
|
|
Two new gastrotrich species belonging to genus Tetranchyroderma are described on the basis of the specimens from intertidal or sublittoral sand bottoms of South Korea. Tetmnchyroderma he te rotentaculatum, n. sp. is clearly differentiated from its congeners by the character combination: the cuticular armature with pentancres, modified rod?like cephalic tentacles, and three pairs of dors o lateral adhesive tubes. Tetranchyro derma hoonsooi, n. sp. possesses tetrancres, paired lateral cephalic tentacles, and ventrolateral adhesive tubes along whole lateral margin, while lacks dorsal adhesive tubes. Affinities with its congeners and variability within the species are discussed, with brief notes on morphological discrepancies between adults and juveniles.
