Zur Formenbildung und Verbreitung der Albinaria-Arten von Kreta; neue Taxa der ‘Gruppe der candida’ (Gastropoda Pulmonata: Clausiliidae)

On the speciation and distribution of the Albinaria species from Crete; new taxa in the ‘Candida group’ (Gastropoda Pulmonata: Clausiliidae) Two new Albinaria species, viz. A. ulrikae spec. nov. and A. violacea spec. nov. (consisting of the nominal form and the subspecies A. violacea dextrogyra subspec. nov.) and three new subspecies of A. hippolyti (Boettger, 1878), viz. A. h. hieronymi subspec. nov., A. h. francisci subspec, nov. and A. h. neuteboomi subspec. nov. are described. The new taxa were discovered in central Crete while thoroughly revising the complex Albinaria fauna of that part of the island.
