title: A re-appraisal of the systematic status of selected genera in Palaemoninae (Crustacea: Decapoda: Palaemonidae).
abstract: Recent phylogenetic work (Ashelby et al., 2012) has demonstrated the need for a fresh appraisal of the systematic status of some Palaemoninae genera. In the present contribution the accumulated morphological as well as molecular evidence is reviewed. The genera Palaemonetes, Exopalaemon and Coutierella are demonstrated to be junior synonyms of Palaemon, which now contains 83 species. As a result of this systematic re-arrangement, two replacement names are needed. Palaemon kwantung nom. nov. now replaces Exopalaemon guangdongensis Guo, Wang & Zhang, 2005, nec Palaemon guangdongensis Liu, Liang & Yan, 1990. Palaemon mundusnovus nom. nov. is the replacement name for Palaemonetes intermedius Holthuis, 1949, nec Palaemon intermedius (Stimpson, 1860).
