Type locality. Port Jackson, New South Wales, Australia. Material examined. 1 spec. from Bermagui (400 km S of Port Jackson, Australia), 8/6/1989, Wim Vader collected on a hermit crab in shallow water. Stored at the Australian Museum (AM xxx) Sydney. Remarks. In Haswell (1879) two species of Montagua were described from Port Jackson, Sydney: Montagua miersii , directly followed by Montagua longicornis . It appears that the first was the female, the latter the male of the same species, belonging to Stenothoe . J.L. Barnard (1974) described four species of Stenothoe from Australia. One of these he called Stenothoe? miersi , doubting about the synonymy, as no type material is available. Barnard's description matches the different populations around most of the Australian coastline, also the Lizard Island specimens ( Krapp-Schickel 2009 : 873-875), and again the illustrations given here of a female. Ecology. It may well be that this specimen lived among the encrusting hydroids and bryozoans growing on top of the hermit-crab-shell and thus had no direct association with the crab; it was the only Stenothoe specimen found among many hermit crabs.
