中国近海珊瑚螺科研究及新种记述

STUDY ON THE CORALLIOPHILIDAE FROM CHINA, WITH DESCRIPTION OF ONE NEW SPECIES (GASTROPODA, MURICACEA)

珊瑚螺科Coralliophilidae属腹足纲、新腹足目、骨螺总科。本科动物主要分布于热带和亚热带暖水区,通常栖息于珊瑚礁间和较深的海域。在国内对本科动物除一些零星报道外,尚未做系统研究,作者根据中国科学院海洋研究所历年来收集的标本资料,经整理研究,共鉴定出2 3种,隶属于6属,其中有1个新种和中国4新纪录。

This paper deals with species of the Family Coralliophilidae (Gastropoda, Muricacea) collected from China coast waters. All specimens studied were obtained from collections made by the Institute of Oceanology, Chinese Academy of Sciences. Of the 23 identified species belonging to 6 genera, 1 species is new to science and 4 species recorded for the first time in China (marked with an asterisk *). The species were as follows 1. Latiaxis mawae (Griffith et Pidgeon, 1834) 2. Babelomurex armatus (Sowerby, 1912) 3.Babelomurex japonicus (Dunker, 1882) 4.Babelomurex cariniferoides (Shikama, 1966) * 5.Babelomurex lischkeanus (Dunker, 1882) 6.Babelomurex princeps (Melvill, 1912) * 7.Babelomurex spinosus (Hirase, 1908) 8.Babelomurex diadema (A. Adams, 1854) * 9.Mipus gyratus (Hinds, 1844) 10.Mipus eugeniae (Bernardi, 1853) 11.Coralliophila bulbiformis (Conrad, 1837) 12.Coralliophila erosa (Roeding, 1798) 13.Coralliophila madreporara (Sowerby, 1824) 14.Coralliophila neritoidea (Lamarck, 1816) 15.Coralliophila costularis (Lamarck, 1816) 16.Coralliophila wilsoni Pritchard & Gatliff, 1898 * 17.Coralliophila nanhaiensis sp. nov. 18.Rapa rapa (Linnaeus, 1758) 19.Rapa bulbiformis Sowerby, 1870 20.Rapa incurva (Dunker, 1852) 21.Magilus antiquus Montfort, 1810 22.Magilus striatus (Ruppel, 1835) 23.Magilus lamarckii (Deshayes, 1863)Coralliophila nanhaiensis sp. nov.(Fig.15) Holotype locality. Zhubi Reef, Nansha Islands (10°56′N, 114°05′E), depth 1.5-2.0m. Collected by WANG Hong-Fa, 17 May 2002. Holotype. Height 19mm, breadth 12mm. Paratypes. Height 18mm, breadth 10.5mm. Holotype and paratypes stored in the Marine Bio- logy Museum, Chinese Academy of Sciences (Qingdao). Description. Shell small, fusiform in shape. With about 6 whorls, suture slightly deep. Whorls expanded and round, body whorl large, the base of shell shrink. Shell surface with fine spiral cords, on which are small scales, axial ribs weak or not clear. At the base of body whorl and upper part of aperture, there is a row of convex thick rib. Shell surface white. Aperture ovate, inner side light purple or white, outer lip curve in shape; inner lip straight, columella smooth. Anterior canal fine, umbilicus large and deep. Habit and distribution. The newly identified species is uncommon and found in coral reefs in shallow water. Known only from the South China Sea. Remarks. The new species is conchologically close to Coralliphila flava Kosuge, but differs from it by the much expanded and rounded whorls, body whorl that sculptured with fine spiral cords, and weak or not clear obscure axial ribs. While the body whorl of Coralliphila flava Kosuge with clear axial ribs and thick spiral cords.
