Diagnosis

This species has a characteristic reddish fawn colouration. The male is distinguished by the unique form of the pedipalp with a very large anterior process of a complex shape and a strongly sclerotized retrolateral side of the bulb (Fig. 57B).

Etymology

The specific name is Latin, meaning ‘large’, and refers to the palpal size.
