Neocallichirus taiaro View in CoL Ngoc-Ho, 1995

Neocallichirus taiaro View in CoL Ngoc-Ho 1995: 212–216, figs 1, 2.

Diagnosis. Antenna peduncle exceeding antennule peduncle by half of article 5. Eyestalk distal lobes triangular, rounded, diverging. Major cheliped merus lower margin evenly convex, denticulate; gape simple; fixed finger cutting edge smooth; dactylus cutting edge concave, with weak notch one-third way along. Uropodal endopod posterior margin decidedly oblique, curving continuously to convex anterior margin. Telson tapering from base to continuous rounded posterolateral margin. Maximum cl. 4 mm.

Distribution. Southeast Polynesia ( French Polynesia [type locality: Tuamotu]).

Remarks. Neocallichirus taiaro Ngoc-Ho, 1995 has been treated as a synonym of N. indicus or N. jousseaumei ( Sakai, 1999; Dworschak, 2011b) but the shape of the eyestalk, chelipeds, female pleopod 2, uropod and telson fall outside the variability of N. jousseaumei . None of the specimens of Neocallichirus from French Polynesia seen during this study could be identified as N. taiaro or N. jousseaumei .
