Etymology. The specific name is an adjective referring to the robust appearance of this species.

Diagnosis. Males of Gippsicola robusta   n. sp. differ from G. raleighi   and G. minuta   n. sp. by the presence of a sperm duct with one and a half convolutions, and from G. lineata   n. sp. by having a sub-rectangular bulb with a more thickened embolus ( Figs 7 View FIGURE 7 A –B). Females present the anterior receptaculum shorter than G. lineata   n. sp. and with the glandular ducts area swollen in frontal view and elongated ventral entapophyses ( Figs 7 View FIGURE 7 C –E). This species also presents a whitish abdomen, with an anterior dorsal dark cross-shaped spot followed by pairs of dorsal dark spots not or partially fused fused with lateral dark marks, forming interrupted dorso-lateral dark lines ( Figs 6 View FIGURE 6 A –D).

Description. Male (Holotype). Carapace and chelicerae orange, with cephalic region slightly darker ( Figs 6 View FIGURE 6 A). Endites brownish orange; labium dark brownish orange. Sternum orange, with darker margins and marbled with dark pigment ( Figs 6 View FIGURE 6 B). Legs orange, with pairs I –II darker. Abdomen greyish ventrally ( Fig. 6 View FIGURE 6 B). Total length 10.08; carapace 4.96 long, 3.2 wide. Palps: tibia with the dorso-ventral diameter shorter than the bulb; embolus tubular with a twisted tip ( Figs 7 View FIGURE 7 A –B).
