Comment(s) on data
Macpherson & Robainas-Barcia (2015, Zootaxa) - Galathea polyphemus n. sp. and G. pilosa De Man, 1888 are closely related. There are not clear morphological differences between the two species, but the living coloration provides the differentiation of them. In this new species, the base color of the carapace and abdomen is purple, whereas it is red in G. pilosa. In spite of the morphological proximity, the genetic divergences between the two are enough great to recognize them as distinct species (15. 3 % for COI, 9.4 % for 16S rRNA). (Tab. 1).
