A revision of Charopidae with a finely cancellate protoconch sculpture from mideastern Queensland (Eupulmonata: Charopidae)

Abstract

This study reviews the charopid land snails of mid-eastern Queensland possessing finely cancellate sculpture on the protoconch. Microscopic features of shell sculpture and qualitative and quantitative measurements of conchological features are utilised to delimit species due to lack of animal material suitable for DNA analysis. This study confirms the generic status of Pereduropa Stanisic, 2010 and Isolderopa Stanisic, 2010 and expands the brief descriptions of the species previously described in these genera. One new species of Pereduropa, P. burwelli sp. nov. and three new species of Isolderopa viz. I. teemburra sp. nov., I. diamante sp. nov. and I. whitsunday sp. nov. are described. A new genus, Tristanoropa gen. nov., is diagnosed for two new species T. hughesae sp. nov. and T. conwayensis sp. nov.  Mollusca, Eupulmonata, Charopidae, protoconch sculpture, finely cancellate, new genera, new species.
