).
Ecological notes.
The single specimen was collected in the intertidal zone in crevices of coral rubble, at a salinity of 39 psu.
Previous records.
None.
Remarks.
The variation in the color patterns as well as preliminary molecular data indicate that
A. paracrinitus
, previously considered to be a pantropical species (
Crosnier & Forest 1966
; Chace 1972, 1988;
Banner & Banner 1982
;
Kim & Abele 1988
), is in fact a species complex (
Knowlton & Mills 1992
;
Anker 2001
;
Williams
et al.
2001
; A. Anker, in study). The single specimen from southern
Bahia
has narrow reddish transverse bands on the carapace and abdomen and red-brownish-white mottled major chela (

D). Its taxonomic identity cannot be established until the entire
A. paracrinitus
complex is revised (A. Anker, pers. comm.)
