Poore, G.C.B.Humphreys, W.F.2016-11-212016-11-211992Invertebrate Systematics, 1992; 6(3):719-7250818-01641447-2600http://hdl.handle.net/2440/102657The crustacean order Thermosbaenacea is reported for the first time from the Southern Hemisphere, from almost fresh water in a cave habitat in tropical Western Australia. Halosbaena tulki, sp. nov. belongs to a genus previously known only from saline waters in the West Indies, Columbia and Canary Is. The discovery is consistent with a very ancient origin of the order and distribution of the genus by plate movements following the breakup of Pangaea.en© CSIRO 1992Journal article003005821510.1071/IT99207192-s2.0-00270378922-s2.0-84970627022278062
