The Flabellinidae, a heterogeneous assembly of supposedly plesiomorphic to very derived sea slug groups, have not yet been addressed by integrative studies. Here novel material of rarely seen Arctic taxa as well as North Atlantic, North and South Pacific, and tropical Indo-West Pacific flabellinid species is investigated morpho-anatomically and with multi-locus markers (partial COI, 16S rDNA, 28S rDNA and H3) which were generated and analysed in a comprehensive aeolid taxon sampling. It was found that the current family Flabellinidae is polyphyletic and its phylogeny and taxonomic patterns cannot be understood without considering members from all the Aeolidacean families and, based on a robust phylogenetic hypothesis, morpho-anatomical evolution of aeolids is more complex than suspected in earlier works and requires reclassification of the taxon. Morphological diversity of Flabellinidae is corroborated by molecular divergence rates and supports establishing three new families (Apataidae fam. n., Flabellinopsidae fam. n., Samlidae fam. n.), 16 new genera, 13 new species, and two new subspecies among the former Flabellinidae. Two families, namely Coryphellidae and Paracoryphellidae, are restored and traditional Flabellinidae is considerably restricted. The distinctness of the recently described family Unidentiidae is confirmed by both morphological and molecular data. Several species complexes among all ex-"Flabellinidae" lineages are recognised using both morphological and molecular data. The present study shows that Facelinidae and Aeolidiidae, together with traditional "Tergipedidae", deeply divide traditional "Flabellinidae." Diagnoses for all aeolidacean families are therefore provided and additionally two new non-flabellinid families (Abronicidae fam. n. and Murmaniidae fam. n.) within traditional tergipedids are established to accommodate molecular and morphological disparity. To address relationships and disparity, we propose a new family system for aeolids. Here the aeolidacean species are classified into at least 102 genera and 24 families. Operational rules for integration of morphological and molecular data for taxonomy are suggested. 139 pp., 48 figs, br. gr. 8.…

Condizione: New. 528, col photos, col illus, maps. 285x230mm. HB. NEW. . Text Swedish with species summaries in English. The second volume on molluscs presents the Gastropod subclass Heterobranchia. The 193 species are presented in a systematic order and are described with text and images. Determination keys for all included species. [9789187853678]. …

The second volume on snails presents the lunged snails (Pulmonata). These species are well known and often infamous to gardeners and homeowners. Up to 20 of the book's 193 species can be found in garden environments, and the vast majority are harmless. In addition to the inhabitants of your garden, you will also get to know the lesser-known shells found on fells, and in lakes, forests and seas. I den andra volymen om snäckor presenteras lungsnäckorna. Vinbergssnäcka, trädgårdssnäcka och mördarsnigel är välkända bland många och ofta ökända av husägare. Uppemot 20 av bokens 193 arter kan hittas i trädgårdsmiljöer, och de allra flesta är harmlösa. Utöver invånarna i din trädgård får du även lära känna betydligt mindre kända snäckor på kalfjäll, i sjöar, skogar och hav. 528 pp., color photos, color illustrations, color distribution maps, hardcover 4 [in Swedish]. …
