| Abstract | Two new genera and four new species of Cirolanidae are reported from deep water (c. 440-2,050 m) off New Caledonia. These are Scutulana pezata, gen. nov., sp. nov., Sintorolana atrox gen. nov., sp. nov., Metacirolana neocaledonica sp. nov. and Politolana crosnieri sp. nov. Scutulana is distinguished by the unique pleonal morphology which has pleonites 4 and 5 laterally reduced but not overlapped by pleonite 3, morphology of the frontal lamina, by several mouthpart characters and by pereopod 1 having a setal brush on the dactylus. Sintorolana is closely related to Natatolana, and is distinguished from that genus and the other cirolanid genera by the expanded propodus of the anterior pereopods which are also heavily armed with spines and the elongate haptorial dactylus which extends to the merus. Metacirolana neocaledonica is closely allied to M. fornicata Mezhov, 1981, from which it is distinguished by the ornamentation of the pleotelson. These two species are separated from all others in the genus by the frontal lamina having an acute anteromedial point. Politolana crosnieri sp. nov., the second record of the genus from beyond Atlantic waters, differs from other species of the genus in having a longer uropodal exopod, a pentagonal frontal lamina, and in the proportions of the antennule peduncle articles. |
