Lesser Antilles data
Distribution: ICA (?Guadeloupe). Pelagic (floating objects). Pantropical.
Planes ?major - Guadeloupe , Karubenthos 2012, no station data, coll. D. Lamy, Baie Porte Enfer, 2012, subsurface, 0.5 m, 1 female, MNHN-IU-2013-4171, det. J. Poupin with hesitation [carapace feebly striated as in P. major but with lateral margins not strongly convex, more or less subquadratic, like in P. marinus].
Comment: Planes major is also reported in WA (e.g. Prado & Melo, 2002; Felder et al., 2009) as Planes cyaneus Dana, 1852. Following Ng & Ahyong (2001) and WoRMS (2016) P. cyaneus Dana should be accepted as Planes major (MacLeay).
This record of P. ?major from Guadeloupe is based on the examination of a single specimen with carapace almost smooth, only feebly striated (versus strongly striated in P. marinus). However the lateral margin of its carapace are not convex (as in P. major) but straight (as in P. marinus). The Guadeloupe specimen could also be an hybrid between P. marinus and P. minutus/major (these two species being potential synonyms in Pfaller et al., 2019, Ecology and Evolution, vol. 9, 957-974).
Comment(s) on data
Genomic results presented in Pfaller et al. (2019, Ecology and Evolution, vol. 9, 957-974) indicate that P. minutus (ATL) and P. major (IWP) are probably conspecific and that this 'P. minutus/major species' can hybridizes with P. marinus in the North Atlantic.
