A review of the recent progresses about Italian baleen whale taxonomy and phylogeny is presented together with a summary of the principal studies carried out on this subject in the past 150 years in Italy. A discussion of the chronospecies Balaenoptera acutorostrata cuvieri is presented here which dismisses such taxon in the light of a thorough morphological analysis based upon the examination of a number of mysticete skeletons in the collections of many institutions all over the world. An overview of new mysticete taxa established from the Italian fossil record is also presented together with reconstructions of their skulls. The analysis of the Italian record shows that the Mediterranean basin played a role in the preservation of archaic biodiversity especially concerning the Balaenopteridae. The presence of Eschrichtiidae is also confirmed based on the newly discovered taxon Eschrichtioides gastaldi. The study of the Italian record is, thus, of great help in the reconstruction of the past mysticete biodiversity evolution and in the analysis of the phylogeny of this marine mammal group.

Abstract
A review of the recent progresses about Italian baleen whale taxonomy and phylogeny is presented together with a summary of the principal studies carried out on this subject in the past 150 years in Italy. A discussion of the chronospecies Balaenoptera acutorostrata cuvieri is presented here which dismisses such taxon in the light of a thorough morphological analysis based upon the examination of a number of mysticete skeletons in the collections of many institutions all over the world. An overview of new mysticete taxa established from the Italian fossil record is also presented together with reconstructions of their skulls. The analysis of the Italian record shows that the Mediterranean basin played a role in the preservation of archaic biodiversity especially concerning the Balaenopteridae. The presence of Eschrichtiidae is also confirmed based on the newly discovered taxon Eschrichtioides gastaldi. The study of the Italian record is, thus, of great help in the reconstruction of the past mysticete biodiversity evolution and in the analysis of the phylogeny of this marine mammal group.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
