| Sixteen species of marine Haplosclerida were collected by the CANCAP-expeditions, among which two are new to science, viz. Petrosia canariensis and Oceanapia cancap. The Haplosclerida fauna of the south-eastern part of the North Atlantic, comprising 46 species, is reviewed, discussed and compared with those of neighbouring areas of the North Atlantic (NE Atlantic, W Atlantic, West Indies, Mediterranean). Three distribution patterns are recognized: Mediterranean-Atlantic, endemic and amphi-Atlantic. |

| The present paper consists of a phylogenetic and historical biogeographic analysis of the North Atlantic shallow-water Haplosclerida (Porifera, Demospongiae), and of the Chalinidae in particular. The monophyly of the Haplosclerida is founded on five assumed apomorphous (derived) characters. Six related outgroups, viz. the Esperiopsidae, Desmacellidae, Mycalidae, Myxillidae, Microcionidae, and Axinellida s.l. have been used for establishing the character polarity within the Haplosclerida. A key to the haplosclerid families, the Chalinidae, Niphatidae, Callyspongiidae, Petrosiidae and Oceanapiidae, and a hypothesis on the phylogenetic relationships of the families is presented. Within the Chalinidae, eight monophyletic species groups are distinguished on the... |
