Comment: New genus Williamstimpsonia is from Štev?i? (2011) with type species Xantho stimpsoni A. Milne-Edwards, 1879, an EP species analogous to Xantho denticulatus White, 1848 in WA.

Comment(s) on data
According to note 413 in Felder et al. (2009): Štev?i? (2005) established a new genus Olivioxantho for Xantho denticulatus, which has also been formerly treated by some authors as Xanthodius denticulatus (nb, Olivioxantho treated as a nomen nudum by Ng et al., 2008); present distributional treatment conforms to that of Manning and Chace (1990), who included both Ascension Island and West African records for this species; Guinot (1968a: 712) earlier suggested that the eastern Atlantic form differed in minor morphological features from that of the western Atlantic, but made no subsequent taxonomic reassignment; records include TCWC 2-2247, 2-2248, and 2-2249 from Isla Lobos in the southwestern GMx, ID by J. P. Ray.
