REMARKS

As indicated by Ahyong (2001), Odontodactylus brevirostris sensu Manning (1967b) comprises a complex of at least four species. Manning (1967b) reported two postlarval groups (“small” and “large”) and Michel (1970a) reported two corresponding larval series (“ 16 mm ” and “ 26 mm ”), both as O. brevirostris . The present specimens all correspond to the “large” late-larval and post-larval groups, and are referable to O. brevirostris sensu stricto. Other species in the “ O. brevirostris ” complex all have “small” late-larvae and post-larvae ( Ahyong 2001).

In the present specimens, the number of teeth on the raptorial claw varies from eight to 10, the number of movable spines on the outer margin of the uropodal exopod 9-11, with the distal most extending beyond the midlength to slightly beyond the apex of the distal segment of the exopod.
