The complex case of the calcareous sponge Leucosolenia complicata (Porifera: Calcarea): hidden diversity in Boreal and Arctic regions with description of a new species
Abstract In this study, we present the first integrative revision of the Boreal and Arctic calcareous sponges of the genus Leucosolenia with a specific focus on its biodiversity in the White Sea. The material for this work included a combination of newly collected specimens from different regions of...

The molecular phylogeny analysis supports the species identity of these species. In addition to conventional morphological characters, new informative fine morphological characters (skeleton and oscular crown organization; cytological structure, including morphotypes of symbiotic bacteria) were found, providing a baseline for further revision of this group in other regions.
