摘要：

Two new species of Napaeus are described, from La Gomera and La Palma (Canary Islands). Both species are small, that from La Gomera being the smallest known Napaeus, its shell surface area (plane view) is more than ten times smaller than that of N. bertheloti. The two new species actively disguise their shells with lichens and soil, presumably to reduce predation.
