Abstract

Members of the family Haloclavidae, belonging to the order Actiniaria, are characterized by the presence of a large siphonoglyph next to their actinopharynx and an aboral end without a basal disc. Members of the genus Haloclava Verrill, 1899 have been reported primarily from Europe and America, and have not yet been described from Japanese waters based on the collected specimen. In this study, I describe a new species, Haloclava hercules sp. nov., from the Pacific coast of Japan. This new species is chiefly characterized by cudgel-like blunt massive tentacles with knob-like acrospheres in the outer tentacular cycle and gigantic basitrichs over 250 μm in length, which are the largest known from sea anemones.

海葵中最大的刺胞科;日本Haloclava hercules一新种记述(刺胞目:猕猴桃目:Enthemonae: haloclavae)

属于放线菌目的Haloclavice科的成员，其特征是在其放线咽旁存在一个大的虹吸管，其流产端没有基底盘。Haloclava Verrill属的成员，1899年主要来自欧洲和美洲，尚未根据采集的标本在日本水域进行描述。在这项研究中，我描述了一个来自日本太平洋海岸的新物种，Haloclava hercules sp.nov。这一新物种的主要特征是棒状钝而巨大的触手，在外触手周期中有旋钮状的顶球，以及长度超过250μm的巨大基部，这是已知海葵中最大的基部。
