Stygofauna of the Canary Islands, 9. The amphipod genus Pseudoniphargus (Crustacea) in the Canary Islands

Pseudoniphargus was known from inland stygohabitats in the Iberian peninsula, the Azores, Madeira, N.W. Africa, and Bermuda, but not from the Canary Islands. Systematic sampling in six of the seven larger islands of the latter archipelago has revealed the presence of the genus in Tenerife (4 species), La Palma (2 species), La Gomera (1 species), and El Hierro (1 species). No Pseudoniphargus has been found in Lanzarote and Fuerteventura; Gran Canaria has not been sampled systematically.
