Stenothoe gallensis species complex
Taxonomic Group: Crustaceans-Amphipods


Amphipods of the Stenothoe gallensis species complex are small marine gammaridean amphipods. Stenothoe gallensis was first described in 1904 from Sri Lanka and occurs widely in the Indian Ocean. Similar amphipods were found in tropical to warm-temperate waters around the world, sometimes described under different names. The true identity and origin of this species complex is still being determined. It has been found associated with other marine invertebrates on docks, buoys, and ship fouling, but is also known from mangrove roots, algae, seagrasses and corals. No impacts have been reported for amphipods of the Stenothoe gallensis complex in their native or introduced ranges.
