A new report of the stenopodid shrimp Stenopus devaneyi Goy, 1984 from the Western Indian Ocean

The rare stenopodid shrimp, Stenopus devaneyi Goy, 1984, is reported for the first time in the Western Indian Ocean (WIO), at 60 m depth at Mayotte Island. No specimens were collected but the species is recognized confidently on photographs based on its characteristic colour pattern: two large red spots on the sides of the second abdominal somite. Selected colour photos are presented. Former Indo-West-Pacific records are listed with an updated map for the geographic distribution of this shrimp. A few ecological observations are made.
