Abstract

ABSTRACT Geographic ranges of some members of the genus Crambionella are not clarified so far. In the context of C. annandalei Rao, 1931, which has been reported only from India and Myanmar, herein we document the first record of this species from the coastal waters of Bangladesh, Bay of Bengal, providing a detailed account of characters, morphometric measurements and illustrations. A comparison of morphological features of C. annandalei from different geographic locations and its congeners is presented, including notes on its fishery value. A cautious review on the occurrence of Crambionella species within the Indian Ocean suggests that geographic distributions of each species are constrained within certain areas around their type localities. Thus, C. annandalei, C. helmbiru, C. orsini and C. stuhlmanni occur in the north-east, south-east, north-west and south-west regions of the Indian Ocean, respectively, without or with a minimum overlapping of each other. All four species occur during both summer and winter seasons of the Indian Ocean.

孟加拉国Crambionella annandalei Rao记录，1931年，并对Crambionela属的地理分布进行了综述（Cnidaria：Scyphozoa）

Crambionella属的一些成员的地理分布范围迄今尚未明确。C. annandalei Rao, 1931，仅在印度和缅甸报道过，本文记录了该物种在孟加拉国孟加拉湾沿海水域的第一次记录，提供了详细的特征描述、形态测量和插图。本文比较了不同地理位置的南南达雷及其同属植物的形态特征，并对其渔业价值作了说明。对印度洋内Crambionella物种发生情况的谨慎回顾表明，每种物种的地理分布都局限于其类型位置周围的某些区域。因此，C. annandalei、C. helmbiru、C. orsini和C. stuhlmanni分别出现在印度洋的东北、东南、西北和西南地区，彼此之间没有重叠或只有很少的重叠。这四个物种都出现在印度洋的夏季和冬季。

期刊介绍： Marine Biology Research (MBRJ) provides a worldwide forum for key information, ideas and discussion on all areas of marine biology and biological oceanography. Founded in 2005 as a merger of two Scandinavian journals, Sarsia and Ophelia, MBRJ is based today at the Institute of Marine Research, Bergen, Norway. The Journal’s scope encompasses basic and applied research from all oceans and marine habitats and on all marine organisms, the main criterium for acceptance being quality.
