摘要

拟海葵是海葵科海葵的一个属，其特征是在柱体表面有腱状突起，通常被沙粒覆盖。该属的大多数种产于深度超过200米的地区。最近在日本海域采集了3个标本，正式命名为Paraedwardsia rinkaimaruae sp. 11和Paraedwardsia moroisoensis sp. 11，后者是在6米深的海底采集的，这是该属最浅的记录。此外，p.r inkaimaruae sp. 11 .在其中胶层中有一些袋状结构，这可能是线虫进化的关键。

Sand Armored Edwardsiids: Two New Species of Paraedwardsia (Cnidaria: Anthozoa: Actiniaria: Edwardsiidae) from Japan.

Paraedwardsia, a genus of sea anemones within the family Edwardsiidae, is characterized by tenaculi on the surface of the column, often covered by sand grains. Most species of this genus are known from areas deeper than 200 m. From Japanese waters, three specimens were recently collected, and are formally described here as Paraedwardsia rinkaimaruae sp. nov. and Paraedwardsia moroisoensis sp. nov. The latter species was collected from 6 m depth, and this is the shallowest record of this genus. In addition, P. rinkaimaruae sp. nov. has a few sack-like structures in its mesoglea, which might be the key to the evolution of nemathybomes.

期刊介绍： Zoological Science is published by the Zoological Society of Japan and devoted to publication of original articles, reviews and editorials that cover the broad field of zoology. The journal was founded in 1984 as a result of the consolidation of Zoological Magazine (1888–1983) and Annotationes Zoologicae Japonenses (1897–1983), the former official journals of the Zoological Society of Japan. Each annual volume consists of six regular issues, one every two months.
