title: Towards a revision of the genusPericlimenes: resurrection ofAncylocarisSchenkel, 1902, and designation of three new genera (Crustacea, Decapoda, Palaemonidae).
abstract: Based on recently published molecular phylogenies of Indo-West Pacific palaemonid shrimps and further morphological evidence, the systematic position of several species of the polyphyletic genusPericlimenesis revised. The generic nameAncylocarisSchenkel, 1902 is re-established for the anemone-associatedPericlimenes brevicarpalis.Actinimenesgen. n., is proposed for the anemone-associatedPericlimenes inornatus,Periclimenes ornatellusandPericlimenes ornatus, all of which have a subspatulate first pereiopod.Cristimenesgen. n., is designated for the echinoderm-associated species,Periclimenes commensalis,Periclimenes cristimanus, andPericlimenes zanzibaricus, all with a unique carpo-propodal articulation of the second pereiopods.Rapimenesgen. n.is established for the hydroid and antipatharian-associatedPericlimenes brucei,Periclimenes granulimanus, andPericlimenes laevimanus, for which the long, slender and unequal second pereiopods and prehensile ambulatory propodi are the main synapomorphic characters.
