Etymology.

The species name is derived from the name of the type locality; adjective.

Diagnosis.

Similar to Cocalus gibbosus Wanless, 1981 (see Wanless 1981: fig. 4 A–D) by the shape of tegulum and embolus (Fig. 17 C–D), but different in the shape of RTA. Female copulatory openings (Fig. 18A) resemble Cocalus murinus Simon, 1899 (see Wanless, 1981: 256, fig. 3 A–E), but the epigynal plate has two rectangular and strongly sclerotised posterior projections (Fig. 18A)
