Abstract
The genus Critomolgus Humes and Stock, 1983 represents a group of 34 species of copepods associated with marine invertebrates. Most of these species have been collected in associations with species of the phyla Cnidaria and Echinodermata in several localities in the Indian, Pacific and Atlantic Oceans with three species reported in the Mediterranean Sea. This is the first occasion in which a species belonging to the genus Critomolgus and the family Rhynchomolgidae Humes and Stock, 1972 is recorded for the Gulf of Mexico. Here, we describe a new species of marine copepod, Critomolgus walteri Varela, Price, Middlebrooks et Ambrosio, associated with the octocorals Leptogorgia virgulata (Lamarck, 1815) and L. hebes Verrill, 1869 in 3.3 meters of water in Tampa Bay, Florida. This species possesses characters that unite it with other members of the genus; however, it differs from all other species due to the body length and unique leg 5 and maxilla l characters. This new species provides evidence that much diversity remains to be discovered in the waters of the Gulf of Mexico and future sampling efforts should target this region.
Critomolgus Humes and Stock属,1983年,代表了与海洋无脊椎动物相关的34种桡足类。这些物种中的大多数是在印度洋、太平洋和大西洋的几个地方与刺胞动物门和棘皮动物门的物种相关联地收集的,据报道,地中海有三个物种。这是1972年墨西哥湾首次记录到属于Critomolgus属和Rhynchomolgidae Humes and Stock科的物种。在这里,我们描述了一种新的海洋桡足类物种,Critomolgus walteri Varela,Price,Middlebrooks et Ambrosio,与佛罗里达州坦帕湾3.3米深的水中的八角珊瑚Leptogoria virgulata(Lamarck,1815)和L.hebes Verrill(1869)有关。该物种具有将其与本属其他成员结合在一起的特征;然而,由于身体长度和独特的腿5和上颌骨特征,它与所有其他物种不同。这一新物种提供了证据,表明墨西哥湾水域仍有许多多样性有待发现,未来的采样工作应针对该地区。
