Mayotte data
Etisus dentatus (Herbst, 1785)
Material examined — Mayotte KUW 2009, st. 3, Trévani fringing reef (night), 1-8 m, 1 M 67 x 103 mm (photo), MNHN B32412, MNHN-IU-2009-1174.
Remarks — This big Etisus can be confused with E. splendidus Rathbun, 1906. The two species can be recognized by their live coloration, chocolate brown in E. dentatus instead of bright red in E. splendidus and by a single spine on the carpus of the cheliped in E. dentatus (2 in E. splendidus).
