Rem.:

Bathypelagic (hyperbenthic). Taken by Bradford (1969 b) at greater than 1200 m on the continental slope off NE New Zealand, where it is deduced to have a benthic habitat.
For Bradford (1969 b, p.500), this species differs in several respects from other genera in the Bathypontiidae; of those species which have a female P5 none except Alloiopodus has the exopod of segment 1 of similar shape to that of the other swimming legs. This is the only genus with a very short A1 and with a gripping joint between basipods 2 and 1 of Mxp.
