Two new species of carnivorous sponges of the genus Abyssocladia are described. These sponges were collected from Myojin Knoll, Izu-Ogasawara (Izu-Bonin) Arc, in southern Japan. Detailed morphological observation based on specimen both in situ and preserved revealed functional differentiation of spicule distribution. Abyssocladia natsushimae sp. nov. is distinct within the genus in its mop-like gross morphology, large body size, and soft tissue packed with numerous microspined microstrongyles. Abyssocladia myojinensis sp. nov. is characterized by possession of both typical abyssochelae and palmate abyssochelae. This is the first record of the genus from Japan.
描述了深海枝柱属（Abyssocladia）的两种肉食性海绵新物种。这些海绵采自日本南部伊豆小笠原（伊豆-小笠原）弧的明神礁。基于原位和保存标本的详细形态学观察揭示了骨针分布的功能分化。新物种夏岛深海枝柱（Abyssocladia natsushimae sp. nov.）在该属中具有独特的拖把状总体形态、较大的体型以及充满大量具微刺的微强骨针的软组织。新物种明神深海枝柱（Abyssocladia myojinensis sp. nov.）的特征是同时具有典型的深渊螯和掌状深渊螯。这是该属在日本的首次记录。
