First Australian records of Scalaronoba Powell, 1927 (Gastropoda: Aclididae?), with the description of two new species from Victoria

The marine microgastropod genus Scalaronoba Powell, 1927 (Gastropoda: Aclididae?) is recorded from Australia for the first time, with the new species Scalaronoba kryptopleurakia n. sp. and Scalaronoba arenula n. sp. described from central Victoria. Three other indeterminate Victorian specimens are illustrated and discussed. These are the first records for the genus outside New Zealand. The uncertainty of the familial placement of Scalaronoba is discussed. These species are noted as being amongst the smallest gastropods to be recorded from Victorian waters.
