• 論文の詳細を見る

• A new species of echinoderid kinorhynch, Echinoderes aureus, is described and illustrated using a differential interference contrast microscope with Nomarski optics. The kinorhynchs were collected from washings of a brown alga, Padina arborescens Holmes, growing in tide pools in Tanabe Bay, Honshu Island, Japan. Diagnostic characters of E. aureus are the presence of middorsal spines on segments 6-10, lateral spines/tubules on segments 4 and 7-12, a pair of remarkably large subcuticular scars in a subventral position on segment 3, and an incomplete midventral articulation on segment 4. The positions of numerous sensory-glandular organs, the sizes of various lateral spines/tubules, and the shapes of the terminal tergal and sternal extensions are also diagnostic. Echinoderes aureus constitutes the 59th valid species of the genus Echinoderes and the 15th species described from the Pacific Ocean. This is the fourth representative of Pacific kinorhynchs found only in the intertidal zone and the second Pacific Echinoderes living on macroalgae in tide pools. A dichotomous key to all 59 species is provided.
