( Figs 37 – 38 View FIGURES 37 – 38 )

Type specimens. Holotype, F, Australia: Queensland: Cherry Plain, BM, 12.ii. 1996, O. Seeman, on P. dilatatus   ( S 74092 View Materials ). Paratypes, Bunya Mountains: M, same data as holotype ( S 74093 View Materials ); F, 3 M, Dandabah, 12.ii. 1996, on P. dilatatus   ( S 74094 View Materials - 97); 2 F, M, Little Falls, 13.ii. 1996, from pupal chamber of M. quaestionis   ( S 74098 View Materials - 100). All specimens deposited in QM. M, same data as holotype, deposited in ANIC.

Diagnosis. Both sexes: idiosoma   1100–1140 long; anterior hyaline projection does not extend past CxI; exopodal patterning between CxII –III striped; pedofossae III present, IV absent; seta h 1 with 3 large barbs; distal spine-like process on palp femur minute or absent; one non-filamentous excrescence ribbon-like, the other a short serrated blade; femur III and IV with large lamellae. Female: sternal shield reticulated; seta st 1 20 long, much shorter than base of tritosternum; setae st 2-3 4–10 long, st 4 minute; sternogynial shield smooth, anterior margin straight. Male: tetartosternum absent; presternal processes articulated with sternoventral shield, asymmetrical, the left longer than the right, with truncate tips, directed inwards; sternoventral shield (anterior of genital opening) smooth; seta st 1 50–65 long; genital opening placed between CxII –III, flanked by 8–10 pores.

Description. Female: Idiosoma   1100–1140 long, 820–840 wide; anterior hyaline projection with 1 pair of barbed setae 54–60 long. Tritosternum base 66–67 long, 32–36 wide. Tetartosternum and sternal shield reticulate; tetartosternum crown-shaped; st 1 20 long, st 2 4–8 long, st 3 10 long, st 4 minute. Sternogynial shield 130–138 long, 128–142 wide, smooth, 4–5 pores flanking each side of shield. Ventral shield lineate, smooth in intercoxal region; 1 pair large semi-circular pores posteromedially of Cx IV, 1 pair of eye-like pores, ca. 12 pairs of small round pores, and 13 pairs of small (<5 long) setae. Ventrianal shield 220–225 long, 515–540 wide, with lineate reticulation, paranal setae 80–94 long, other setae minute; anterolateral corner of ventrianal shield not fused with ventral shield. Marginal shields with lineate reticulation. Pedofossae III and CxIV-marginal suture present.

Legs. TrI with seta pv 1 slightly thicker than seta av 1. FeI with seta pv 3 longer and thicker than setae pv 1 and pv 2. FeII with ventral lamella, seta ad 1 barbed and thickened. GeII with seta ad 3 and pd 3 thickened. FeIII with lamella, expanded distal to av 1, seta pv 1 spine-like. GeIII with seta pd 2 spine-like. FeIV with lamella, expanded distal to av 1, seta pv 1 thick, spine-like, seta ad 2 thickened, seta pd 2 in line with or just proximal to seta ad 2. TaII –IV with seta av 2 spine-like, shorter than seta av 3. Legs II –IV with setiform ad and pd setae.

Gnathosoma   . Seta h 1 curved, with 3 large barbs, 67–69 long, distance between h 1 –h 1 10–12; h 2 with 3 small barbs, 53 long; h 3 10–11 long, posterolaterad h 2; palpcoxal seta 22–25 long. Corniculi not on tubercles. Palp, seta av 1 on trochanter with 18–20 barbs, 61 long; av 2 with 3 small barbs, 63 long. Chelicera, fixed digit 200–205 long, movable digit 62 long; fixed digit with 2 large and 1 minute subapical tooth; excrescences consist of a large brush-like process, a short serrated blade, and a ribbon-like process with a toothed margin that extends well beyond the end of chelicerae.

Male: Idiosoma   1150 long, 850 wide. Tritosternum base broad, 70–72 long, 82–84 wide. Presternal processes asymmetrical, left process longer than right, broadly attached to sternal shield and pointing inwards; right process with a tooth-like ridge, left process with a longitudinal ridge. Sternal shield anterior of genital opening smooth. Seta st 1 smooth, 50–65 long. Genital opening 78–80 long, 72–75 wide, with 8–10 large pores laterad the opening. Large lamellae on Cx I. Gnathosoma   . Seta h 3 posterolaterad h 1, anterior h 2.

Remarks. This species is found in the Bunya Mountains and is common on M. quaestionis   .

Etymology. The specific name is derived from the type locality, the Bunya Mountains.
