Head. Rostrum absent or vestigial; Lateral cephalic lobes apically round, anteroventral margin moderately excavate, moderately recessed. Antenna 1 flagellum with 21 or more articles; accessory flagellum present and multiarticulate. Antenna 2 with few long setae. Labium with fine setae and stout setae. Maxilla 1 inner plate with 1 long pectinate apical seta. Maxilliped basis without strong flange on anterior margin. Mandible, palp article 3 longer than 2, posterior margin straight or weakly falcate, posterior margin with setae of two distinct lengths, long setae and an understory of much shorter regularly spaced setae.

Peraeon. Sternal spines absent. Gnathopod 1 enlarged in males only; coxa distinctly produced anterodistally, acute; basis robust, half or more as broad as long, without a spine, anterior margin without stridulating ridges, posterodistal margin with setae sparse or absent, anterodistal margin with flange weak or absent, with a weak distomedial lobe or absent; ischium anterior margin without flange, posterior margin with setae sparse or absent; merus not greatly elongated, fused along its entire length with carpus, posterior margin with dense rows of setae, without posterodistal spine; carpus two thirds length of propodus, anterior margin without stridulating ridges, with setae sparse or absent, anterior surface with no spine, without an oblique row of long setae on medial face, posterior margin without spines; propodus longer than carpus, anterior-distal margin densely clothed in long setae, posterior margin straight or evenly convex, palm present, palm delimited from posterior margin, margin entire, palm defined by strong posterodistal spine, without robust seta defining palm, without spine near base of dactylus; dactylus about half length of propodus, significantly overlapping palm. Gnathopod 2 subchelate; basis anterodistal margin without flange, posterodistal margin without robust setae; with few setae along length of basis; carpus longer than propodus, anterior margin not lobate, densely setose; propodus densely setose, palm with robust seta(e) defining palm. Pereopod 6 basis produced posterodistally into a distinct "heel".

Pleon. Epimeron 3 posterodistal margin produced into a small spine. Uropod 1 biramous, rami rami subequal, peduncle much longer than broad, distoventral interramal spine shorter than peduncle. Uropod 2 peduncle with distoventral interramal spine. Uropod 3 biramous, rami subequal, inner ramus subequal with length of peduncle. Telson with distal fine setae and robust setae.

Habitat. On fine sand and among algae (Myers, 1982a).

Depth zones. Littoral.

Distribution. Mediterranean Sea.

Peraeon. Gnathopod 1 coxa distinctly produced anterodistally, sub-acute; posterior margin with sparse setae or setae absent; palm defined by rounded or oblique corner or corner undefined, with robust seta defining palm; fitting palm. Gnathopod 2 carpus subequal with or shorter than propodus, moderately to sparsely setiferous.
