Calcareous sponges of the subclass Calcinea from Martinique (Caribbean Sea) are presented under an integrative perspective (morphology and DNA: ITS and C-LSU). Eleven species of six genera have been found in Martinique, three of them being new to science: Borojevia crystallina sp. nov., Clathrina delicata sp. nov., and Ernstia adunca sp. nov. Among these new records, four species were previously known from other Caribbean localities: Arturia vansoesti, Clathrina insularis, C. mutabilis, and Leucaltis clathria. Two species previously known in Brazilian waters are reported for the first time in the Caribbean Sea: Arturia alcatraziensis and C. cf. cylindractina. Finally, the occurrence of C. aurea and Leucetta floridana in Martinique is confirmed. The two molecular markers (ITS and C-LSU) and the morphological characters considered (e.g. body shape, aquiferous system and spicules) provided congruent classifications what tend to confirm their reliability for the taxonomy of Clathrinida. After the present work, a total of 17 species of Calcarea are recognised for Martinique. We discuss three types of distribution patterns (Endemic, Caribbean-Brazil, and Amphi-Atlantic), Martinique likely playing an important role as stepping stone to garantee connectivity among populations of Calcinea in the Atlantic.
本文从综合角度（形态学和DNA：ITS和C-LSU）介绍了来自马提尼克岛（加勒比海）的钙质海绵亚纲钙质海绵。在马提尼克岛发现了六个属的11个物种，其中三个是科学新物种：晶状博罗耶维亚海绵（Borojevia crystallina sp. nov.）、精致克氏海绵（Clathrina delicata sp. nov.）和钩状恩氏海绵（Ernstia adunca sp. nov.）。在这些新记录中，有四个物种此前在加勒比海其他地区已知：范氏阿图里亚海绵（Arturia vansoesti）、岛屿克氏海绵（Clathrina insularis）、多变克氏海绵（C. mutabilis）和格子状白钙海绵（Leucaltis clathria）。此前在巴西海域已知的两个物种首次在加勒比海被报道：阿尔卡特拉齐阿图里亚海绵（Arturia alcatraziensis）和圆筒形克氏海绵（C. cf. cylindractina）。最后，确认了金色克氏海绵（C. aurea）和佛罗里达亮钙海绵（Leucetta floridana）在马提尼克岛的出现。两种分子标记（ITS和C-LSU）以及所考虑的形态特征（如体型、输水系统和骨针）提供了一致的分类，这倾向于证实它们对克氏海绵目分类的可靠性。经过目前的研究，马提尼克岛共识别出17种钙质海绵。我们讨论了三种分布模式（特有、加勒比-巴西和两洋分布），马提尼克岛可能作为一个重要的踏脚石，以确保大西洋钙质海绵亚纲种群之间的连通性。
