Comment: Presence of Armases cinereum in West Indies is doubtful as Abele (1992: 32) indicates that: 'Records of this species (A. cinereum) from the West Indies and elsewhere were based on misidentified material'. Armases cinereum is affiliated to A. ricordi (Abele, 1973: 378), common around Guadeloupe, therefore Desbonne's record of Sesarma cinerea is probably of A. ricordi instead.

Comment(s) on data
Abele (1992) - Armases ricordi is one of the more terrestrial species in this group. It occurs among supratidal litter to several hundred meters inland. Specimens were collected from dry areas above mangrove swamps, in pinewoods on islands in Dade County, Florida, in grass above sandy beaches and among limestone rubble at the edge of a reef flat. Verrill (1908a,b) records a "variety" of this species from dry upland fields in Bermuda but doesn't say how far these were from water.
