Abstract 

Pallidelix Iredale, 1933 is revised on the basis of conchological and anatomical morphology. Nine new species Pallidelix lonesome sp. nov., P. expeditiana sp. nov., P. potteri sp. nov., P. staricki sp. nov., P. lambkinae sp. nov., P. moffatt sp. nov., P. grandis sp. nov., P. minerva sp. nov. and P. zamia sp. nov. are described. Penial pilaster patterns and shell sculpture were considered significant species delimiting characters. A key to species is presented. Two species are shown to have relatively widespread distributions while the majority have small circumscribed distributions in scattered and isolated patches of vine thicket. Two species placed in Pallidelix by Stanisic et al. (2010) from south-eastern Queensland, viz. H. bennetti Brazier 1872 and P. chinchilla Stanisic, 2010 are herein excluded from the genus. As part of this revision the taxonomic status of the problematic Helix expeditionis Cox, 1868 (considered a synonym of P. greenhilli by Stanisic et al. 2010) is also discussed.
