Type Material:
Cotton [1939:172], Kaicher [1980:EP2-3044], and Brown & Neville [2015:158] all reported the holotype as D.13300, held by the South Australian Museum. However, this catalogue number has not been able to be located in the South Australian Museum's online collections database [South Australian Museum, 2026].
The following list brings together type material and other cited specimens as reported in the sources examined, grouped under the names and designations used in each source. The same specimen may appear in multiple entries drawn from different sources. Some entries concern other species included by authors for comparison; inclusion in this list does not imply synonymy.
