Xeromiturga pilbara sp. nov.

Fig. 78

Diagnosis. Differs from males of Xer. gumbardo sp. nov. in lacking patellar processes on the palp, and from Xer. bidgemia in the embolus being directed transversely retrolaterad, not diagonal to base (Fig. 78a). Female unknown.

Type Material. Western Australia: male holotype, Pilbara region, ca. 8 km W of Newman, 23°24’S 119°37’E, 14 Mar–20 May 2010, pitfall trap, J. Gollan, AM KS120129.

Description. Male, holotype AM KS120129

Carapace 2.43 long, 1.80 wide. Opisthosoma 2.75 long, 1.70 wide. Total length, 5.18.

I: 2.33, 0.94, 2.10, 1.97, 0.99, 8.33. II: missing. III: 2.10, 0.54, 1.34, 2.10, 1.25, 7.34. IV: 1.84, 0.94, 1.88, 2.24, 1.34, 8.24. Palp: 0.99, 0.42, 0.46, -, 2.71, 3.26.

Palp. Patella without process. Tibia short; RTA long trianguloid without distinct distal lobe, dorsal lobe short spiniform. Cymbium aspinose, with distinct retrolateral groove almost for length; tegulum reniform, transverse; embolus base smaller, gourd-shaped, directed transversely retrolaterad, embolus very long; median apophysis large with large triangular process near base of embolus, large, flared areas constricting to a ridged fold with simple short acuminate tip.
