Examination of the morphology of palaemonine shrimps from Tasmania and south-eastern Australia, and molecularanalyses by other authors, necessitated an examination of the validity of some characters used for generic differentiationwithin the Palaemoninae and a redefinition of the genus Palaemon. A new species, Palaemon dolospina sp. nov., isdescribed from Margate Beach in south-eastern Tasmania. Palaemon intermedius (Stimpson, 1860) is redescribed. Bothspecies vary between localities across southern Australia. Keys are presented for the small estuarine and marine shrimpsof Palaemoninae in southern and south-eastern Australia belonging to genera, Palaemon and Palaemonetes. One speciesof Palaemon has been introduced to Australia from overseas. |
