Filistata gibsonhilli Savory, 1943: 355 View in CoL . Female lectotype and paralectotype (designated and illustrated by Marusik et al. 2019) from Australia, Christmas Island, 1939, C.A. Gibson-Hill leg., deposited in the Oxford University Museum of Natural History, not examined.

Labahitha gibsonhilli View in CoL – Zonstein & Marusik 2019: 86. — Marusik et al. 2019: 258, figs 1–4.

Notes

Marusik et al. (2019) examined and figured the holotype of this species. We here illustrate the male for the first time ( Fig. 13 View Fig ).

Diagnosis

The male is similar to that of Labahitha fuscata in the sharp, triangular apex of the paraembolic lamina and the gently curved distal portion of the sperm duct. It differs by the longer and slender palpal bulb and the relatively smaller paraembolic lamina ( Fig. 13B View Fig ) (vs palpal bulb shorter and stouter, with larger paraembolic lamina in L. fuscata ). Females are more similar to those of L. oonopiformis and L. garciai by the large membranous base of the receptacles and well-developed median receptacle; they differ from these species by the curved median receptacles with pores restricted to medial face ( Marusik et al. 2019: fig. 4) (vs median receptacles globose with pores distributed evenly).

Material examined

AUSTRALIA • 1 ♂; Christmas Island ; AM .

Distribution

Known only from Christmas Island, Australia ( Fig. 1B View Fig ).
