Stygofauna of the Canary Islands, 4. Liagoceradocus acutus Andres, 1978, a blind anchihaline amphipod from Lanzarote: redescription, taxonomic status and occurrence

Liagoceradocus acutus Andres, 1978, has been found in different localities on Lanzarote, Canary Islands. A redescription is provided and the taxonomic status of the genus Liagoceradocus is discussed. The species shows sexual dimorphism mainly in the morphology of the propodus of gnathopods 1 and 2, but not in the pleopods. It was previously only known from the type-locality, the Jameos del Agua lava tunnel (Lanzarote), but is by no means specific to this kind of of habitat: it occurs regularly, and sometimes in great abundance, in subterranean shafts formerly used to supply the island’s salt pits with seawater.
