(Acari, Oribatida, Selenoribatidae)}, year = {2013}, keywords = {Bermuda, speciation, morphometrics, cytochrome oxidase I, Carinozetes bermudensis }, doi = {}, url = {http://}, pmid = {}, journal = {BMC Evolutionary Biology}, volume = {}, number = {}, pages = {}, abstract = {The small archipelago of Bermuda is a geologically young landmass in the Western Atlantic Ocean and recently turned out to be a hotspot for intertidal oribatid mites. More than six new species belonging to two families could be found. One of these species, Carinozetes bermudensis, showed an unusual vast range of microhabitats and specimens occurring on mangrove roots slightly diverged from specimens found in other habitats. In the present study, a total of 13 Bermudian populations of the intertidal oribatid mite species C. bermudensis were analysed to verify the species integrity of specimens dwelling in different microhabitats. A morphometric analysis of 21 continuous variables as well as a molecular genetic investigation of the mitochondrial cytochrome oxidase subunit I revealed the existence of a new species Carinozetes mangrovi sp. n., inhabiting exclusively intertidal algae growing on mangrove roots. Although both species are morphologically nearly identical, a clear diagnostic character could be detected: in C. bermudensis the genus-specific ventral carinae are straighter and situated closer to each other than in C. mangrovi. Carinozetes bermudensis and C. mangrovi have occupied different ecological niches and the high genetic divergence of approximately 12% of the COI gene sequence between the two species suggests that these species diverged five to six million years ago. Accordingly, both of them are older than the geologically young archipelago of Bermuda and we suggest that speciation took place somewhere in the Central American or Caribbean area. } }
