On La Gomera fossil shells of a new mollusc species were found that, due to the discoidal shape and large umbilicus, bear a strong resemblance to species of the genus Canaridiscus. The new species is described and is compared with other Canarian species of the genus.
On La Gomera, fossil shells of an obviously new small species were found. Due to the similarity with Vitrea and Spelaeopatula, the new species has been classified in the Pristilomatidae. Based on four specimens, the species is described in the new genus Gomerella. The most striking feature is a pseudosuture on the umbilicus side of the body whorl.
The subgenus Simplicula Ponte-Lira & M. R. Alonso, 1997 in the genus Canariella P. Hesse, 1918 is elevated to the rank of a genus and seven new fossil taxa of the group are described from Pliocene and Pleistocene to Holocene deposits from the North of Lanzarote, La Graciosa, and the North, West and Northwest of Fuerteventura, Canary Islands. Their relationship to other taxa of the family Canariellidae on the Canary Islands and in the West-Mediterranean region as well as with fossil species from continental Europe placed in the genus Canariella is discussed.
Four fossil species of Napaeus from various parts of the Canary Island of La Gomera are new to science. The species are described and compared with other species of this genus. Including these four species, there are now 31 Napaeus species known from La Gomera and 76 species from the whole Canary archipelago. La Gomera is as such by far the most diverse island with respect to Napaeus.
A new fossil species of the genus Canariella, C. gerti, classified in the subgenus Majorata Alonso & Ibáñez, 2006, is described from Quaternary eolianites from the northwestern part of Fuerteventura, Canary Islands. Its relationships to other taxa of the family occurring on the Canary Islands and especially on Fuerteventura are discussed.
