( Figures 1 C – E, 11A – E, 13A – E, 15)

Wandella murrayensis Gray 1994 , p. 52, figs. 7, 9, 21, 27 – 29, 61 – 63, 82 – 86, 96 – 97.

Holotype male from Felixstowe, Adelaide, SA, on bank of Torrens River at junction with Forth Creek, 35°46' S, 138°36' E, 7/IX/1985, D. Hirst, under Eucalyptus bark, deposited in SAM ARA 5311(l1), not examined. Male and female paratypes from Parra Wirra NP, Sth Parra River (AM KS.35718*), examined.

Distribution

Southeastern South Australia, southwestern New South Wales and Victoria ( Figure 15 ). Additionally, I have examined a single female from Western Australia ( Figure 13 A); finding males would be desirable to confirm this record, which might represent an introduced population.
