Differs from  Miturgopelma brevirostra  sp. nov.in the extensive “gaping”, unsclerotised area of the RTA, a wide gaping area ( Fig. 52e); and the basal embolus edge within basal half of bulb ( Fig. 52c). Female unknown.   Etymology.The species epithet is a noun in apposition from the typelocality.   Type Material.  Western Australia: male holotype, Grasspatch, ‘Sieda’, 33°14”S 121°43”E,  19 Nov 1996, A.F.

Palp: 1.25; 0.63; 0.44; -; 1.25; 3.56. Colour: Carapace with two moderately dark shell-like areas laterally; opisthosoma, dorsally dark, mottled with long ovoid paired pallid regions flanking poorly defined medial dark band; ventrally mottled lightly but uniformly; femora strongly mottled and broadly banded, base and apex of pedal tibiae and to lesser extent metatarsi dark orange brown with lighter orange median zone. Eyes: All similar, small; ALE clearly smallest. Posterior row eyes more or less overlapping; PME and PLE inner edges well separated. Legs moderately long. Spines: femora pv1 on I–IV; tibiae I, II p2d1–3r2 on I, II; palp fe with p1; ti with d1–2; cymbium 2 basal, 2 mid-proventral edge. Palp: Patella dorsally with distal point interlocking with sclerotised notch on basal tibia; tibia clearly smaller and shorter than patella; ventral ridge on tibia rounded, defining glabrous ventral concavity on tibia; cymbium with two large spines on edge and two midbasally mixed with uniform cover of hairs and long spine-like bristles with slight ovoid scopula; retrobasally with unmodified, narrow edge; ventral lobe short blunt triangular; dorsal lobe a scalloped plate without bifid tip or barb; RTA distal; short, directed laterally; two plates sandwiching large extensive unsclerotised zone; base of ventral lobe with triangular process; embolus origin at mid-length, base curves sharply. MA area about as wide as long with small weakly sclerotised zone almost to tip, 6-shaped.   Distribution.Known only from Grasspatch, south-west Western Australia. 4442871472 1996-11-19 WAM A. F.
