| Abstract |
The recent revision for the species of the complex of Bursa scrobilator (Linnaeus, 1758) for the Atlanto-Mediterranean area recognized the existence of three morphologically distinct taxa: two Recent, Bursa scrobilator scrobilator (Linnaeus, 1758) and Bursa scrobilator coriacea (Reeve, 1844) currently considered subspecies, and the fossil and extinct Bursa nodosa (Borson, 1825). Recently, the phylogenetic relationships of bursid gastropods has been reconstructed and the generic name Talisman de Folin, 1887, based on a larval shell of “Bursa” scrobilator scrobilator, has been resurrected. Consequently, the two subspecies are now named as Talisman scrobilator scrobilator and Talisman scrobilator coriacea. During the check of the Italian fossil specimens of the T. scrobilator complex, in addition to the specimens of the well-known B. nodosa, has been separated a second fossil and extinct species that despite careful research, could not be identified with the fossil species currently known for Italian paleontological deposits: this is here described with the name of Bursa transeuntis n. sp. The morphological relationships of B. transeuntis n. sp., B. nodosa and related taxa are also discussed. |
