Fig. 12B

Aparatanais tetradonta: Bird (2015) : 397 –400, figs 26–28, 400, table 2; Bird (2019): 71, table 10.

Material examined. Non-ov. ♀, 1.8 mm, AMS P.105586, SWP2017-143-2.

Distribution. Macauley Island, 13– 16 m.

Remarks. This record supplements a previous example from Macauley Island in addition to those from several islands in the Raoul group ( Bird 2015: 397, 399), at depths 10– 27 m. The sampled habitat here is novel, being encrusted coral on rocks. Another Pacific species, A. hawaiensis Morales-Núñez, Pelleteri & Heard, 2016 has been described recently, together with a comprehensive key to the species of Aparatanais (ibid: 489–490).
