摘要

布莱克福德水母属的水螅水母目前由三个描述的物种组成：曼哈滕水母、弗吉尼亚水母和多齿水母。这些物种的区别在于性腺的位置和形状、边缘触须的数量以及钟形边缘是否存在黑色色素。我们第一次在越南发现了一种黑藤属植物。形态学和分子分析表明，与同类动物相比，这种越南黑福藻的触手数量适中，只有巴西、墨西哥和印度的黑福藻也有类似数量的触手。线粒体DNA分析表明，越南黑福氏菌与来自巴西的“B.virginica”形成亚支，并与来自其他地方的B.virginia不同，K2P距离>0.13。这些结果表明，在越南（和巴西）发现的Blackfordia sp.可能与在其他地方发现的B.virginica不同，尽管还需要更多的信息来确定这个新物种。

Morphological and molecular analyses of Blackfordia sp. (Hydrozoa: Leptothecata) newly discovered in Vietnam

Hydrozoan jellyfish of the genus Blackfordia currently consist of three described species: B. manhattensis, B. virginica and B. polytentaculata. These species are distinguished by combinations of the position and shape of the gonads, the number of marginal tentacles, and the presence or absence of black pigments on the bell rim. We discovered a species of the genus Blackfordia in Vietnam for the first time. Morphological and molecular analyses revealed that this Vietnamese Blackfordia had an intermediate number of tentacles compared with its congeners, and a similar number of tentacles had been reported in Blackfordia only in Brazil, Mexico and India. Mitochondrial DNA analysis indicated that Vietnamese Blackfordia formed a sub-clade with “B. virginica” from Brazil, and differed from B. virginica from other locations, having a K2P distance of >0.13. These results suggest that Blackfordia sp. found in Vietnam (and Brazil) may be a different species from B. virginica found elsewhere, though more information is needed to establish this new species.

期刊介绍： Plankton and Benthos Research is a peer-reviewed journal publishing quarterly original papers, reviews and notes dealing with any aspect of the biology and ecology of planktonic and benthic organisms and their interactions with the environment in any aquatic system, and is open to all scientists around the world. Submission of a paper is held to imply that it represents an original contribution not previously published and that it is not being considered elsewhere.
