Seeman, on M. quaestionis   ( S 74209 View Materials - 10); 2 M, JSF, Peter’s Rd, 17.iii. 1996, O. Seeman, on M. quaestionis   ( S 74211 View Materials - 12); M, Mt Tamborine, 8.ix. 1996, N. Power & D. White, on M. quaestionis   ( S 74213 View Materials ) All specimens deposited in QM.

Diagnosis. Both sexes: idiosoma   1390–1520 long; anterior hyaline projection does not extend past CxI; exopodal patterning between CxII –III striped; pedofossae III present, IV absent; seta h 1 with 6–7 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 35 long, shorter than base of tritosternum; setae st 2-4 <10 long; sternogynial shield smooth, anterior margin straight. Male: tetartosternum absent, presternal processes articulated with sternoventral shield, symmetrical, with truncate ends, directed inwards; sternoventral shield (anterior of genital opening) reticulate; seta st 1 50–60 long; genital opening placed between CxII –III, flanked by 12–18 pores.

Remarks. The holotype and paratypes are in good condition. This species is found in Southeast Queensland on M. quaestionis   and specimens from my collections are larger than Womersley’s ( idiosoma   1450– 1520 long), but morphologically alike.
