 Issued from : J.C. von Vaupel-Klein in Zool. Verh. Leiden, 1970, 110.

Rostrum simple, with a minutely bifurcated tip. 1st metasomal segment and cephalosome fused, Th4 and Th5 fused. Posterolateral corner of metasome with a spiniform process, extending a little beyond middle of genital segment; A1 reaching to about distal end of genital segment. 2nd exopodal segment of A2 with a large internal process carrying 1 seta. basis of Md with 2 subequal setae. Mx1 with 14 setae on 1st, 4 each on 2nd and 3rd inner lobes, 5 on basis; 14 on endopod; 11 on exopod; 9 on outer lobe. Coxa of Mxp without a lamelliform outgrowth.

 Gaetanus simplex female: 1 - Anterior part of cephalon with frontal spine. 2 - Exopodal segment 1 of A2 without seta; exopodal segment 2 with 2 setae (1 medial situated and 1 distal). 2nd internal lobe of Mx1 with 4 setae. Exopod of P1 always with 2 external spines. 3 - Mxp protopodite without lateral plate. 4 - Exopod of P1 2-segmented, or indistinctly 3-segmented.

La signalisation de cette espèce en antarctique par Hopkins (1985, p.167) et Hopkins & Torres (1988, p.82, tab.2) dans la mer de Weddell) est probablement une confusion avec Gaidius intermedius Wolfenden,1905 = Gaetanus brevispinus (Sars,1900) et probablement aussi pour Rau & al., 1991 (p.1, fig.1);
