ETYMOLOGY: The specific name, an adjective, is derived from the name of the

Greek island where the new species was found.

DIAGNOSIS: The species is characterised by the shape of the palpal tibia and the absence of the anterior radical process in the embolic division.

DESCRIPTION: Male paratype. Total length 1.58. Carapace modified as shown in Figs 125 & 126, 0.75 long, 0.53 wide, pale brown with indistinct radial bands. Chelicerae 0.20 long, unmodified. Both holotype and paratype have white, almost transparent (probably bleach) legs. Leg I 2.10 long (0.60+0.15+0.60+0.45+0.30), IV 2.18 long (0.60+0.18+0.60+0.50+0.30).
