Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.168, Fig.84]. Female juv.5 (from NW Pacif.): habitus (dorsal); S4B1, distal inner largin of basipodal segment 1 of P4.

Plate 3 issued from : E.L. Markhaseva in Zool. Zh., 1980, 59 (4). [p.627, Figs.1, 4-11]. Female (from 45°20'-46°04'N, 153°03'-153°55'E): 1, habitus (lateral); 4, head (lateral); 5-6, posterior prosome and urosome (lateral and dorsal, respectively); 7, Mxp; 8, syncoxa of Mxp); 9, P1; 10, P2; 11, P4.
Plate 4 issued from : E.L. Markhaseva in Zool. Zh., 1980, 59 (4). [p.627, Figs.1-3]. Females: Comparison between the most closely related species G. paracurvicornis (1), G. curvicornis (2) and G. latifrons (3). 2 and 3 from Sars, 1924-1925.
Plate 5Gaetanus paracurvicornis female: 1 - Anterior part of cephalon with frontal spine. 2 - Exopodal segment 1 of A2 with 1 seta, exopodal segment 2 with 2 setae. 2nd internal lobe of Mx1 with 5 setae. 3 - Exopod of P1 indistinctly 3-segmented, with 2 external spines. Lateral plate of Mxp protopodite reduced, sometimes there are visible traces of the plate.
bathy & abyssopelagic. Sampling depth (Antarct.) : 3000-5000 m. For Brodsky (1967, p.168) this species resembles G. secundus Esterly in the form of the frontal spine and the length of the thoracic spines; it differs in its much shorter A1.
