changes as males grow, with the propodus becoming curved and slender in larger males. The carpus comes more elongate in larger males with the length to breadth ratio increasing from 1.1:1 in males less than 3 mm, 1.2:1 in males up to 3.5 mm and 1.9:1 in the holotype (3.8 mm in length). On the carpus, the anterodistal tooth near the articulation with the propodus becomes more prominent in larger males. In males less than 3 mm in length the tooth is absent, and poorly defined in males up to 3.5 mm. The tooth is small but well defined in the holotype. The palm of gnathopod 2 is straight rather than excavate as in most species of
