TL;DR: Shell-bearing slugs of the Canary Islands, so far assigned to the genus Par- macella, were studied, and two new species from Lanzarote and Alegranza are described, thus raising the number of Canarian taxa of Cryptella to seven.
Abstract: Shell-bearing slugs of the Canary Islands, so far assigned to the genus Par- macella, were studied. The taxon Cryptella, currently considered as a subgenus of Par- macella, is regarded as a full genus, and two new species from Lanzarote and Alegranza are described, thus raising the number of Canarian taxa of Cryptella to seven. With a total of 8 species {Cryptella 7, Parmacella 1) the Canary Islands constitute one of the centers of diversity of the family Parmacellidae.
