Introduction

Pupisoma orcula is a wide ranging species having been recorded from South Africa, India, Indonesia, New Guinea, Hawaii. The species was first from Australia by Solem (1989). Pupisoma porti from eastern Australia may be a synonym but topotypic collections of this species will be necessary in order to resolve the issue. Recorded from Kimberley coast by Köhler et al. (2012: 26).
