| The examination of a few colonies of compound ascidians belonging to the genus Didemnum collected at Pulau Islet in the Singapore area leads to the discovery of two new types of Copepods Notodelphyidae. Both belong to a genus recently found in the Gulf of Eilat (Red Sea), the genus Achelidelphys. This discovery which is important from the zoogeographical point of view, strenghtens a previous phylogenetic hypothesis. [NOT CONTROLLED OCR] |

| Based upon a large collection from the western Mediterranean, a description of a new genus of notodelphyid parasitic copepod from didemnid ascidians is given. The new genus Anoplodelphys is erected for three new species found in different host species. Anoplodelphys clearly belongs to the ophioseidimorph group of notodelphyids ; within this group, the genus is mainly distinguished by the complete lack of true buccal appendages, feature in common with only four previously described species. The discovery of this new genus increases the polyphyletic trend within the ophioseidimorph notodelphyids. The host specificity is extremely narrow : all three new species of Anoplodelphys live in several species of the large genus Didemnum. Some remarks on the host... |

| Two stays in Eilat laboratory (Red Sea) enable to gather a large collection of the family Didemnidae.The examination of the parasitic copepods Notodelphyidae found in these colonies leads to describe three genera and five species of Notodelphyidae new to science, all of them belonging to the polyphyletic group ophioseidimorph : Achelidelphgs gen. n., Cephalodelphys gen. n. and Syndelphys gen. n. These three genera are remarkable by the morphological reductions of the appendages : the antennule is the single appendage existing in two of them; it lacks in the third genera.The antenna and the mouthparts have disappeared in three genera.The parasitic specificity is rather strict.A comparison of the evolutionnary trends in both Didemnidae and their... |
