Port Lincoln, South Australia.
Molecular and morphological analysis#R has shown that the characters defining the forms semitorquatus, macgillivrayi and barnardi are unstable and inconstant, and that genetically there is poor evidence for recognizing more than one species (B. zonarius), with just two subspecies (zonarius and barnardi). While a single species of Barnardius is accepted here, with synonymization of races occidentalis and whitei (recognized in HBW), four populations are judged to be sufficiently distinct, despite remarkable degree of variation within each one, to warrant subspecific recognition (following main published authority#R). Forms myrtae and dundasi are, like occidentalis, included within nominate zonarius; form whitei is judged to be an intergrade between nominate and barnardi. Four subspecies recognized.
