Unverified, CMNZ , see methods section for comment . Type locality. Ross Beach , Westland and Kaiapoi Beach , South Island , New Zealand . Size. Male 12 mm , female 14 mm . Remarks. The original description and illustration by Hurley adequately define and typify the taxon. No additional material of this species could be located in museum collections to establish a habitus illustration or better understand growth stage development of male sexually dimorphic characters. Despite the limited availability of material for study, Bellorchestia spadix is well diagnosed as a species and easily distinguished among New Zealand coastal talitroids based on the male dimorphic pereopods ( Fig. 68 ). Habitat. S upralittoral. Distribution. New Zealand . South Island: Ross Beach, Westland and Kaiapoi Beach ( Hurley 1956 ).
