Notes on Japanese Ahermatypic Corals -II New Species of Dendrophyllia

Abstract

Four new species of Dendrophyllia are described and figured. D. suprarbuscula n.sp. was found at 90 m, off Izu Hachijou Island, and D. paragracilis n. sp. in the shallow marine cave of Ogasawara Islands and Ryukyu Islands. Other two new species, D. futojiku n. sp. having big columellae and D. minima n. sp. having the smallest corallites, were found in shallow waters of Izu Hachijou Island. We revised the key to 20 species of Dendrophyllia and related genera in Japan including new species.

Ahermatypic corals (Scleractinia: Dendrophylliidae, Oculinidae and Rhizangiidae) recorded from submarine caves in Hong Kong

“…Marine caves in the Indo-West Pacific may be, therefore, important habitats for ahermatypic corals. Nevertheless, there have been few other reports on scleractinians from submarine cave habitats although Dendrophyllia paragracilis has been described as a new species from the shallow marine caves of Ogasawara and the Ryukyu Islands, Japan (Ogawa and Takahashi 2000).…”

A New Record of Dendrophyllia compressa (Anthozoa: Hexacorallia: Scleractinia: Dendrophylliidae) from Korea

“…-7.9-13.0 (10.9) Takahashi (1995), and Tachikawa (2005) pointed out in the description of D. compressa (Table 2). Dendrophyllia compressa Ogawa and Takahashi, 1995 is similar to D. minima Ogawa and Takahashi, 2000 in its bushy growth form, small calicular diameter, presence of Pourtalès Plan, and presence of epitheca. However, the former species differs from the latter species with regard to the larger calicular diameter, more numerous septa of hexa merous 5 cycles, and wider costae (Ogawa and Takahashi, 2000) (Table 2).…”
