The genital apertures in the female are situated on slight eminences at the distal ends of the second coxae of all legs, but in the males these apertures are restricted to a similar position on the third and fourth pairs of legs. The apertures are much smaller in the males. There appears to be a considerable range of variation in the

It is with some hesitation that I propose this further addition to the already unwieldy genus Nymphon, but whilst this species has no remarkable features, the combination of the features it possesses seems to separate it from other rather similar species. N. maoriana falls amongst those species placed in "Group I" by Gordon (1932b), and is rather similar to N. subtile Loman, but is distinguished from this species by the closer spacing of the lateral processes and the greater number of spinules on the fingers of the chelae.
