Hamalpheus acanthops, new genus, new species, a stygiophilic alpheid shrimp from a Samoan lava tube
Abstract
Alpheid shrimps are abundant in marine habitats, particularly in the tropics and on coral reefs. Few occur in brackish or fresh waters and their occurrence in troglobitic situations is particularly rare. Potamalpheops stygicola (Hobbs, 1973) has been reported from a fresh-water cave in Mexico and two species of Metabetaeus, M. lohena Banner and Banner, 1960, and M. minutus (Whitelegge, 1897) occur in anchialine lava and coral pools (Holthuis, 1986). The present shrimp appears to be the first alpheid shrimp to be found in a marine lava tube.
