Streptacis Meek, 1872
Remarks. This genus is introduced for the first time to the Australian fauna to accommodate Loxonema elegantissima Yoo, 1988, Streptacis gundyensis n.sp. and Streptacis sp. Loxonema elegantissima is here transferred to the genus Streptacis because of its minute shell with strong sinuous collabral lirae.
Australian Carboniferous species. Streptacis elegantissima (Yoo), from 'Marohn'; Streptacis gundyensis n.sp., from 'Marohn'; Streptacis sp. (in this study), from 'Kyndalyn'.
