[1] However, Forster's 1954 revision of the genus Sorensenella noted there was only a single specimen in the British Museum, and that Pocock's description also implied this.

S. prehensor nitida was differented on the basis of geographic range and eyemound characteristics.

Forster's redescription based on a greater range of material than was available to Pocock notes the following additional characters.

Colour reddish brown with a black pattern on the scute (the unsegmented portion of the carapace).

[2] Sorensenella p. prehensor may be separated from S. p. obesa by the latter's greater size and slightly backward-pointing eyemound tubercle.

Both are found at North Cape, with S. p. obesa confined to a separate population in the northernmost part of the region.
