Goreopagurus lemaitrei Nucci & Melo, 2007: 52 , figs 1, 2. — McLaughlin et al., 2010: 29.

Material examined. Brazil, Ceará, Canopus Bank. Holotype: male (3.5 mm SL) (MZUSP-17645). Paratypes: 1 female (3.0 mm SL) (MZUSP-17646); 7 females (2.1–3.0 mm SL) and 1 female with shield broken (MZUSP- 17647).

Diagnosis. Shield as long as broad. Rostrum obtusely triangular, with or without small terminal spinule. Lateral projections rounded or slightly triangular. Ocular peduncles moderately stout; dorsal face with row of 3 tufts of setae, 1 tuft of setae on mesial margins, near posterior margin of corneae. Ocular acicles triangular, with strong submarginal spine; dorsal surface concave. Antennular peduncles overreaching distal margins of cornea by approximately half length of terminal segment. Antennal peduncles overreaching distal corneal margins by approximately 0.4 length of terminal segment. Right cheliped very elongate; cutting edge of dactyl with 3 or 4 calcareous teeth in proximal half, 1 broad calcareous tooth and row of very small corneous teeth in distal third, terminating in small corneous claw. Left cheliped long and slender; dactyl and fixed finger arched ventrally; dactyl approximately 3.0 length of palm; cutting edge with row of tiny corneous teeth. Ambulatory legs similar from left to right; dactyls approximately as long as or slightly longer than propodi; lateral faces each with very weak longitudinal sulcus. Meri of first pair of ambulatory legs with longitudinal sulcus on lateral face. Males without sexual tube on either coxa of fifth pereopods. Telson with posterior lobes separated by deep median cleft.

Distribution. Known only from the type locality, off Fortaleza, Ceará, Brazil.

Habitat. All specimens were collected at 350– 400 m.

Remarks. The characters of the Brazilian species, Goreopagurus lemaitrei , agree with the recently emended diagnosis ( Lemaitre & McLaughlin 2003). Females have first paired pleopods; the male has no trace of a sexual tube; the gills are biserial; and all the specimens examined exhibit dimorphism of the right cheliped, although in larger specimens this dimorphism is less notable than in other species of the genus.
