Notes on Japanese Ahermatypic Corals-I -New Species and Subspecies of Culicia and Phyllangia-

Abstract

A new subspecies, Culicia japonica tenuisepes, found in shallow waters of Tsukumo Bay, Sea of Japan and two new species, Culicia subaustraliensis from shallow waters and Phyllangia echinosepes from 90 m depth off Izu Hachijo Island, the Pacific coast of Honshu are described and illustrated. These species differ from hitherto known species or subspecies not only morphologically, but also by morphometrical features such as the correlation between calice diameter and septal number or the ordering of septal width.

New Records of Two Genera Leptoseris and Phyllangia (Anthozoa: Hexacorallia: Scleractinia) from Korea

“…Phyllan gia hayamaensis (Eguchi, 1968) is similar to P. echinosepes Ogawa, Taka hashi and Sakai, 1997 in the encrusting growth form of cylindrical corallites basally united with common coenosteum, and the hexamerous arrangement in four incom plete cycles. However, the latter species differs from the for mer species by its small calicular diameter, numerous septa, and distinctive spinous ornamentations of the septal lateral faces (Ogawa et al, 1997).…”

“…In the original paper (Eguchi, 1968), this species was named as Astrangia hayamaensis, and was characteri zed by the octamerous three incomplete cycles. However, the genus was changed from Astrangia to Phyllangia (Cairns, This study Wells (1954), Dinesen (1980), Veron (2000) Dinesen ( 1980 Korean name: 1 *찻잔돌산호속 (신칭), 2 *찻잔돌산호 (신칭) 1994; Ogawa et al, 1996) based on the pre sence of paliform lobes and the smooth septal inner edges (Cairns, 1994;Ogawa et al, 1996;Cairns and Kitahara, 2012). Furthermore, it was corrected and redescribed that the septal arrangement of the species is irregular, but basi cally hexamerous in four incom plete cycles (Ogawa et al, 1996).…”

Furthermore, it was corrected and redescribed that the septal arrangement of the species is irregular, but basi cally hexamerous in four incom plete cycles (Ogawa et al, 1996). The specimen from Mara do is distinguished by its greater number of septa (average 39.4) than those describ ed in previous records from Japan (Eguchi, 1968;Ogawa et al, 1996Ogawa et al, , 1997, in addition to the intratentacular bud ding of an enlarged corallite with a cali cular diameter of 7 × 11 mm and 56 septa (Table 2).…”
