Introduction

The recent description of B. kobylianskyi Gon & Stewart 2014 from New Zealand based on specimens originally misidentified as B. problematicus has raised some doubt over the presence of B. problematicus in Australia. Furthermore, a key to the genus provided by Kobyliansky (1990) also listed B. kobylianskyi misidentified as B. problematicus (see Gon & Stewart 2014). While records of B. problematicus from Australia may prove to be misidentifications we retain the species here until Australian museum records can be re-examined.
