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 genus Periclimenes swisse high strength magnesium powder berry is revised.The generic name Ancylocaris Schenkel, 1902 is re-established for the anemone-associated P.brevicarpalis.

Actinimenes gen.n., is proposed for the anemone-associated P.

inornatus, P.ornatellus and P.ornatus, all of which have a subspatulate first pereiopod.

Cristimenes gen.n., is designated iphone 13 atlanta for the echinoderm-associated species, P.

commensalis, P.cristimanus, and P.zanzibaricus, all with a unique carpo-propodal articulation of the second pereiopods.

Rapimenes gen.n.is established for the hydroid and antipatharian-associated P.

brucei, P.granulimanus, and P.laevimanus, for which the long, slender and unequal second pereiopods and prehensile ambulatory propodi are the main synapomorphic characters.
