Bouvieraxius longipes (Bouvier, 1905)



World Distribution
Sakai (2011, Axioidea of the world: 80) - Porto Rico, Barbados, 255 m. (Porto Rico probably by error from Bouvier, 1905: 804, as this place is for Axiopsis defensus Rathbun)

Bouvieraxius ?longipes - Guadeloupe (first record?), Karubenthos II 2015, field det. J. Poupin, st. CP4558, 15 June 2015, 16°21.98'N, 60°48.72'W, 385-312 m, MNHN-IU-2013-18968; st. DW4612, 24 June 2013, 16°19.3'N, 60°50.94'W, 290-250 m, no MNHN (photo T. Magniez); st. DW4647, 29 June 2015, 15°50.29'N, 61°26.24'W, 263-264 m, MNHN-IU-2013-19179.
Comment: Among differences with Bouvieraxius longipes there are low spines on upper margin of larger chelae that are not illustrated/indicated in Bouvier (1925) and the submedian carinae have 4 spines instead of 3 indicated by Bouvier (1925). However, Poore & Collins (2009) indicate that this character can varies from 3-4 in Bouvieraxius keiensis Sakai, 1992 (cf. mail P. Dworschak September, 2015). Bouvieraxius longipes is indicated by error from Puerto Rico (300 m), as type locality in Sakai & de Saint Laurent (1989), because Bouvier (1905, 1925) mentions only Barbados for this species.

Comment(s) on data
For a species in Paraxiopsis the antennal acicles of the Guadeloupe Karubenthos 2015 specimens are too long (cf. P. Dworschak, mail September 2015).
