Sažetak
Selected species of the following dasyclad genera, deriving from Barremian and Aptian deposits of the Adriatic and Dinaric karst, are elaborated: Salpingoporella, Acroporella, Actinoporella, Clypeina and Praturlonella. A new genus, Piriferella, is established. Descriptions of the following Salpingoporella species are completed with newly established characteristic features and illustrated with appropriate sections: Salpingoporella muehlbergii, S. melitae, S. hispanica, S. hasi, S. urladanasi, and S. dinarica. In addition, the following new species are described: S. verrucosa, S. heraldica, and S. polygonalis. Apinella jafrezoi, the type species of the genus Apinella, is considered to be a younger synonym of Salpingoporella hispanica. Actinoporella podolica and Acroporella radoicicae are commented upon. Praturlonella danilovae is illustrated. Selliporella dalmatica and Likanella pejovicae have been transferred to Praturlonella. Because the problematic Halicoryne nerae has also been transferred to the genus Praturlonella (with itšs inadequate diagnosis and description), a new diagnosis and more complete description of this species is given. Clypeina? solkani is illustrated by Barremian specimens and Clypeina gigantea n.sp. from the Lower Barremian of Mljet Island is described. Beside the type-species, Piriferella spinosa, the species hitherto labelled Clypeina somalica, or Similiclypeina somalica, has also been transferred to the new genus Piriferella.
