Miturgopelma brevirostra sp. nov.

Figs 18–19

Diagnosis. Males most closely resemble those of Miturgopelma sieda sp. nov., but differ in the distal embolus-basal embolus edge within distal half of bulb (Fig. 19a), and a subtle unsclerotised area on the median apophysis. Female unknown.

Etymology. The species epithet refers to the short, beak-like median apophysis.

Type material. Western Australia: male holotype, 39 km E. of Laverton, 28°28’S 122°50’E, pitfall traps, 22–26 December 1990, E. R. Pianka, WAM 98 /756.

Paratypes. 4 ma., same data as holotype, WAM 98 /757-760.
