P1 : inner margin of coxa, basis, and proximal endopodal segments ornamented with groups of stout spinules ; middle part of distomedial seta of distal exopodal segment with stout barbs ; distal exopodal segments with small, curved proximal spinules. P2 : distomedial margin of distal endopodal segment ornamented with setules ; inner margin of 1st exopodal segment with row of spinules. P3 : distomedial margin of distal endopodal segment ornamented with setules ; inner margin of 1st exopodal segment with a row of spinules in distal and one in proximal parts of segment

Female: A, P1: endopods, exopod, coxal and basal inner margins (posterior; small curved spinule of exopod arrowed); B, endopod and exopod of P2 (posterior; ornamentation with spinules arrowed); C, endopod and exopod of P3 (posterior; ornamentation with spinules arrowed); D, 1st somite of urosome and genital double-somite (another aberrant specimen).

Rem.: Ivanenko & Defaye (2006, p.722) remark: G.O. Sars (1900) descibed Mormonilla polaris from the Arctic Ocean and indicated the lack of differences bertween this species and Mormonilla minor Giesbrecht (1891). later, Farran (1908- synonymized this species with M. minor. For the authors this species requires re-establishing the validity of Mormonilla polaris and placing it in the new genus Neomormonilla
