Etymology. Chthamalus williamsi is named in honour of Prof. Gray A. Williams, Director of the Swire Institute of Marine Sciences, School of Biological Science, the University of Hong Kong, for life-long friendship and mentorship with the first author and for his contributions to the intertidal ecology in the South China Sea. Distribution. Chthamalus williamsi sp. nov. is common inside crevices of the mid shore of the intertidal zone, and on the shell surfaces of the barnacle Megabalanus volcano (Pilsbry, 1916) and M. tintinnabulum (Linnaeus, 1758) on low shores of the eastern waters of Taiwan. Chthamalus williamsi has not been identified previously from Taiwan as it is not easily spotted, due to its small size and low shore location. This species is absent from the N and NE coasts of Taiwan although intensive sampling was conducted (Fig. 1), suggesting its distribution may be associated with the Kuroshio Current. Molecular analysis. From both maximum likelihood and Bayesian inference trees of a COI region, Chthamalus williamsi shows a distinct divergence from C. challengeri, C. dalli, C. moro, C. malayensis and C. sinensis (sequence divergence> 0.13 K 2 P distance from all the Chthamalus species compared; Table 1). Chthamalus sinensis and C. neglectus grouped in the same clade, suggesting C. neglectus is a synonym of C. sinensis (see Liu & Ren 2007 for synonyms of C. neglectus and C. sinensis).Published as part of Chan, Benny K.
