Comment(s) on data
Dardanus sanguinolentus (Quoy & Gaimard, 1824) for long considered as a junior synonym of D. lagopodes (the red knee form; see Malay et al., 2018).
An affiliated species to D. lagopodes/D. sanguinolentus is Dardanus umbella Asakura, 2006 from Yap Island, Micronesia. In his thesis, Landschoff (2018: 160) has tentatively identified 'red knee' specimens from South Africa to Dardanus cf. umbella. He has also indicated that 'red knee' D. sanguinolentus reported in this base (Poupin & coll.) from Mayotte and Réunion could be also 'D. cf. umbella'. However in his synthesis (p. 210) Landschoff indicates that his 'D. cf. umbella' from South Africa 'seems to be conspecific with Malay et al's (2018) specimens of D. sanguinolentus' and that 'future studies are likely to show that the latter taxon (D. umbella) is actually a synonym of D. sanguinolentus.
