摘要

在臺灣南部沿岸的珊瑚礁上發現了一種與星孔珊瑚共生的藤壺。牠是新屬新種，命名為宋氏高柱藤壺。牠外壁表面有高的隆起，以往認為此類構造是簡單的裝飾，但實際上是此共生藤壺自己產生的。此種與其它所有同一分類族的藤壺的差別，在於牠具有癒合的體壁以及完全鈣化的蓋板，其內面有狹長型的突起，而外有長條、已覆蓋的溝狀構造。

Cionophora n. gen. is proposed for the coral-inhabiting barnacle Cionophora soongi n. sp. This obligatory symbiont lives on the hermatypic coral Astreopora sp. found in nearshore waters along the southern coast of Taiwan. The external surface of the wall develops tall pillars, a unique feature previously interpreted as simple ornamentation, but herein recognized as an integral part of the barnacle's symbiotic relationship with the coral. Cionophora soongi differs from all other known Pyrgomatini by possessing both a coalescent wall and fully calcified opercular plates, and in having a long, slender tergal spur with a closed external longitudinal furrow.
