Remarks

Tenagomysis producta has only been previously recorded from the Bay of Islands, northern New Zealand ( Tattersall 1923).

The material reported here agrees with the original description except for the armature of the uropodal endopod, which is armed with four to eight spines arranged irregularly on the ventral surface of the basal part in addition to the spines on the mesial ventral margin ( Fig. 7 G); in the original description the existence of these spines was not noted, possibly having been overlooked.

All the pleopods of the present female specimens are knife­shaped, as are those of T. longisquama . The apex is rounded however.
