2026-08-19 eng 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.

Support for this work was provided by grants (TMI) from the United States National Science Foundation (BSR-8700079) and the National Geographic Society (#3412-86). Invaluable assistance for the study was generously supplied by Mr. Dan Sua and the Western Samoa Department of Fisheries. Yolanda Iliffe also assisted with cave collections. Dr. Yasuhiro Miya kindly provided much helpful advice on the key to alpheid genera. notPlanned A. J. Bruce Division of Natural Sciences, Northern Territory Museum
