Sampling depth (Antarct., sub-Antarct.) : 0-600; 100-1000 m.
According to Vervoort (1951, p.82) , the female of Gaidius intermedius (= Gaetanus brevispinus) is easily recognized by the distinct, ventrally curved, slender lateral spines, the tubercle on the 2nd exopodal segment of A2, the lamella on the 1st segment of Mxp (acutely pointed in the specimens from the 'Willem barendsz' collection) and the shape of the rostrum; the short, notched rostrum is so much depressed that it points obliquely downwards; it is so much hidden by the basal portions ofthe A1 that it is almost invisible. The rostrum makes it distinguishable from the closely allied Gaetanus affinis, described by Sars (1905, 1925).
