“Jaeropsis stebbingi sp. n.
Jaeropsis curvicornis non Nicolet, Barnard, 1914: 224, p1. 20c; 1940: 434, 494; 1965: 202, fig. 2c. Menzies & Schultz, 1967: 174. Stebbing, 1905: 51, p1. 11 (fig. C).
Diagnosis
Cephalon with frontal plate rounded, medially entire, lateral margins entire. Lateral margins of pleotelson usually with four very fine serrations on each side, often difficult to detect. Uropodal basis with broadly rounded medial lobe tipped with short hook, hardly interrupting pleotelsonic marginal outline; medio-distal margin serrulate. Cephalon bearing broad curved dark pigment band.

Remarks
As noted by Barnard (1965) and Menzies & Schultz (1967), the Jaeropsis curvicornis described by Stebbing (1905) from Ceylon and later recorded from South Africa was probably not the same as J. curvicornis described by Nicolet (1849) from Chile. From the excellent figures provided by Menzies & Schultz (1967) of J. curvicornis (Nicolet), from the Antarctic, it is immediately apparent that the South African species is not the same as the Antarctic—Subantarctic species. The most obvious differences are to be seen in the uropods (curved and hooked in J. stebbingi, straight and elongate in J. curvicornis), the rostral plate (evenly convex in J. stebbingi, truncate with small median tooth in J. curvicornis) and in the lateral margins of the pleotelson (serrate in J. stebbingi, with a single strong incision in J. curvicornis).”
