Annotated type catalogue of Bothriembryon (Mollusca, Gastropoda, Orthalicoidea) in Australian museums, with a compilation of types in other museums

Type material of 41 Australian Bothriembryon taxa present in Australian museums is critically listed, indicating systematic issues that need to be resolved in further studies. Information on additional type material of 22 taxa in non-Australian museums is compiled. The seven fossil taxa known so far are included in this catalogue. Based on the current systematic position, 38 species are treated in this paper. B. jacksoni Iredale, 1939, B. notatus Iredale, 1939, B. praecelsus Iredale, 1939 and B. serpentinus Iredale, 1939 are elevated to species level. B. gratwicki (Cox, 1899) is listed as status to be determined.
