Salvador
, “Almirante Saldanha”, st. 1981b, 1 spec. (MZUSP-8910).
Diagnosis.
Shield longer than broad. Rostrum triangular or rounded, sometimes with terminal spinule. Lateral projections broadly triangular, with small marginal or submarginal spine. Ocular peduncles moderately short; corneae slightly dilated; ocular acicles long, triangular, with small submarginal spine. Right cheliped with ventral margins of merus tuberculate or spinose; carpus with dorsal face slightly tuberculate; dorsal surface of palm and fixed finger distally tuberculate; dactyl with dorsal median row of tubercles. Left cheliped with 1 spine and few spinules on ventrolateral margin of merus; dorsolateral margin of carpus with strong spine; chela unarmed or with 2–4 small spines proximally. Dactyls of second and third pereopods longer than propodi. Telson with terminal margins oblique, each armed with several strong spines.
Distribution.
Western Atlantic:
United States
(North Carolina to Florida),
Bahamas
, Gulf of
Mexico
,
Colombia
, Guyanas and
Brazil
(from Amapá to Bahia).

From shallow waters to
210 m

Remarks.
Phimochirus holthuisi
is very close to
P. operculatus
(
Stimpson, 1859
)
, a species not found in
Brazil
. According to
McLaughlin (1981b)
,
P. holthuisi
varies widely both morphologically and in pigmentation, and these variations are unrelated to the location or depth of collection.
