| Cosmotropical species reported in the genus Acarnus, viz. A. innominatus Gray (1867), A. tortilis Topsent (1892) and A. souriei Levi (1952), are demonstrated to show small, but consistent interregional morphological differences, leading to the conclusion that these “species” are very probably complexes of closely related species derived from former widespread (Tethyan and/or Gondwanan) ancestors. On the basis of this analysis, six regional Acarnus forms are described as new species, viz. A. claudei n.sp. from South East Africa (formerly described as A. innominatus by Lévi, 1963), A. hoshinoi n.sp. from NW Australia (formerly described as A. innominatus by Hooper, 1986) A. deweerdtae n.sp. from the West Indian region (newly discovered material related to A.... |

| Comparison of Sollasella digitata Lendenfeld, 1888, up until the present assigned to its own family Sollasellidae Lendenfeld, 1887 in the order Hadromerida, and Raspailopsis cervicornis Burton, 1959, assigned to Raspailiidae Nardo, 1833 in the order Poecilosclerida, leads to the conclusion that both should be considered congeneric and are best assigned to a single genus Sollasella. This conclusion is based on examination of habit and skeletal characters of the type material of S. digitata and both type and freshly collected material of S. cervicornis. The conclusion is strengthened by the discovery of a new species, Sollasella moretonensis n.sp. collected in North Australia (primarily in the northeastern coast, but also an isolated record from the... |

| This is the second part of a revision and re-classification of the demosponge family Sollasellidae, and an example of a successful use of combined morphological and molecular data. Sollasella had been a poorly known, long forgotten taxon, placed incertae sedis in the order Hadromerida in the last major revision of the demosponges. It has recently been suggested to belong to Raspailiidae in the order Poecilosclerida due to striking morphological similarities. The present analysis verified this re-classification using molecular markers. Comparing 28S rDNA fragments of Sollasella cervicornis, a newly described species S. moretonensis and a representative set of raspailiid and hadromerid samples. In our analyses Sollasella clearly clusters inside the... |
