Abstract

Nineteen new species of Charopidae are described from mainly limestone habitats in eastern New South Wales. Eleven new genera are introduced and some existing genera and species revised. Rhophodon Hedley, 1924 is more clearly defined and R. palethorpei sp. nov., R. silvaticus sp. nov., R. mcgradyorum sp. nov. and R. duplicostatus sp. nov. are described from limestone and rainforest habitats in NE NSW; Egilodonta Iredale, 1937 (type species: Charopa bairnsdalensis Gabriel, 1930) is removed from the synonmy of Rhophodon and E. wyanbenensis sp. nov., E. bendethera sp. nov. and E. paucidentata sp. nov. are described from restricted limestone localities in SE NSW; Letomola lanalittleae sp. nov. is described from restricted limestone localities in the Macleay Valley, NE NSW; Macrophallikoropa gen. nov. is introduced for the widespread, moist forest dweller Helix belli Cox, 1864 and M. stenoumbilicata sp. nov. and M. depressispira sp. nov. are described from restricted localities in the Sydney Basin Bioregion; Allocharopa Iredale, 1937 (type: Helix brazieri Cox, 1868 from the Sydney Basin Bioregion) is shown to be a synonym of Elsothera Iredale, 1933; Egilomen Iredale, 1937 is redefined and a new diagnosis is presented for the type, E. cochlidium (Cox, 1868), which is restricted in distribution; Whiteheadia gen. nov. is introduced for Egilomen globosa Stanisic, 1990; Coricudgia wollemiana gen. et sp. nov. is described from Mt Coricudgy, Wollemi NP; Decoriropa gen. nov. is introduced for the widespread Helix lirata Cox, 1868; Marilyniropa jenolanensis gen. et sp. nov. is described from limestone localities near Jenolan, SE Oberon; Cralopa Iredale, 1941 is redefined and revised diagnoses and new distribution details are presented for the widespread C. stroudensis (Cox, 1864) and C. kaputarensis Stanisic, 1990 from the Nandewar Range; Gouldiropa gen. nov. is introduced for C. carlessi Stanisic, 1990 which is redefined and restricted in distribution to the northern New England Tableland; Sharniropa gen. nov. is introduced for S. wollondillyana sp. nov. and S. borenorensis sp. nov. from limestones in the Abercrombie and Orange areas of central NSW respectively, S. xanana sp. nov. from limestone outcrops in the southern New England Tableland; Acheronopa attunga gen. et sp. nov. is described from limestones in the Manilla-Attunga region of the New England Tableland; Hedleyropa yarrangobillyensis gen. et sp. nov. is described from the Yarrangobilly limestones of SE NSW; Scelidoropa gen. nov. is introduced for the widespread S. sarahjaneae sp. nov. and the narrowly restricted S. nandewar sp. nov. from the Nandewar Range; Diphyoropa gen. nov. is introduced for Helix saturni Cox, 1868 from the Sydney Basin Bioregion and D. macleayana sp. nov. from the Macleay Valley, NE NSW. Patterns of morphological variation are analysed and discussed and a phylogenetic hypothesis for the species is presented based on 32 shell characters and 12 anatomical characters. Biogeographic discussions focus on the effects of climate-induced fragmentation and isolation of mesic communities since the Miocene on species distributions and the role of limestone outcrops as important secondary refugia (next to rainforest) for this biota. A conservation priority for these species is outlined.
