介形类新种,Semicytherura sagittiformis sp. 11月,是在日本中部静冈县的沙滩上描述的。它生活在海洋沙质沉积物的孔隙水中,在生态上与其他间质介形类动物(例如副水母和微甲壳动物)有联系。 Semicytherura sagittiformis 是 Semicytherura 属中最小的物种之一,其甲壳大小与一些大型间质介形类相当。这一事实表明,小甲壳是介形类适应间隙环境的最重要特征。
A new species of ostracod, Semicytherura sagittiformis sp. nov., is described from a sandy beach in Shizuoka Prefecture, central Japan. It lives in pore-waters of marine sandy sediments and is ecologically associated with other interstitial ostracods (e.g., Parapolycope and Microloxoconcha). Semicytherura sagittiformis is one of the smallest species in the genus Semicytherura, and its carapace size is comparable with those of some large interstitial ostracods. This fact suggests that a small carapace is the most important character for adaptation of ostracods to an interstitial environment.
