Abstract

Two new species, Plicatellopsis borealis and Spongosorites beringensis, from the Bering Sea are described; both belong to genera previously not reported from the area. The genus Plicatellopsis, Burton, 1932 (Porifera, Suberitida, Suberitidae) contains five valid species, all recorded from the southern hemisphere. The record of P. borealis n. sp. from the Bering Sea is consequently the first record of the genus from the northern hemisphere. The genus Spongosorites Topsent, 1896 (Porifera, Suberitida, Halichondriidae) contains 22 valid species but none reported from the North Pacific Ocean, Bering Sea or the Arctic Ocean. The geographically closest records are six species occurring in the North Atlantic Ocean. So the description of Spongosorites beringensis n.sp. is the first record of the genus in the region.

摘要

描述了来自白令海的两个新物种，北方褶板海绵（Plicatellopsis borealis）和白令海绵瘤（Spongosorites beringensis）；这两个物种都属于此前该区域未曾报道过的属。褶板海绵属（Plicatellopsis），由伯顿于1932年建立（多孔动物门，软海绵目，软海绵科），包含五个有效物种，均记录于南半球。因此，北方褶板海绵新种（P. borealis n. sp.）来自白令海的记录是该属在北半球的首次记录。海绵瘤属（Spongosorites），由托普桑于1896年建立（多孔动物门，软海绵目，硬海绵科），包含22个有效物种，但此前没有在北太平洋、白令海或北冰洋的报道。地理上最接近的记录是在北大西洋出现的六个物种。所以，白令海绵瘤新种（Spongosorites beringensis n.sp.）的描述是该属在该区域的首次记录。
