Etymology. The specific name, excavatus, Latin, refers to the excavate anterior margin of the lateral cephalic lobes. Diagnosis. Lateral cephalic lobes broadly rounded, distinctly excavate along anterior margin; eyes apparently absent. Epistome and upper lip bounded by slight slit, upper lip projecting in front of epistome. Gnathopod 2 coxa well developed. Pereopod 3 coxa slightly expanded distally. Pereopods 5–7 with small spurs on anterodistal corner of propodus; coxa 5 and 6 producing posterior lobe, narrowly rounded ventrally. Epimeron 3 posterior margin smooth. Uropod 3 rami subequal in length; outer ramus article 2 more than half the length of article 1. Telson deeply cleft to 65% of length, lobes subtriangular. Description of male holotype. Head deeper than long; lateral cephalic lobes broadly rounded, distinctly excavate along anterior margin; rostrum absent; eyes apparently absent. Antenna 1 peduncle article 2 about half the length of article 1; flagellum missing from specimen. Antenna 2 article 3 short, subequal in length and breadth; article 4 the longest; flagellum 7+ articulate, broken at seventh article; calceoli absent. Mouthpart bundle subquadrate.
