Right cheliped with ventral face and margins of merus spinose; carpus with dorsomesial and dorsolateral margins ornamented with row of spinules; dorsal surfaces of palm and dactyl unornamented, dorsomesial and dorsolateral margins crenulate. Left cheliped with dorsolateral margin of carpus ornamented with row of strong spines and dorsomesial margin with row of smaller spines; dactyl and fixed finger ventrally spoon-shaped. Dactyls of second and third pereopods strongly curved, ventral margins each with row of setae. Telson with terminal margins oblique, each armed with 3 or 4 strong spines.

Remarks.
Phimochirus occlusus
is close to
P. leurocarpus
McLaughlin, 1981
(species not recorded from
Brazil
) but the two species can be distinguished by the rows of spines on the ventral margins of the dactyls, present in
P. leurocarpus
and absent in
P. occlusus
.
