Decapoda - Stenopodidea - Stenopodidae - Richardina
Felder et al. (2009) - 400-1230 m. Fla Keys, E Atl. (for R. spinicincta; R. fredericii is from Mediterranean).
Environnement : Marine - Substrat/Association : Hard bottom (rock and rubbles)
Vertical range : Deep (more than 100 m) - Min-Max observed: 400-1230 m
Lesser Antilles data
Distribution: Florida Keys and eastern Atlantic. Lesser Antilles, ICA (Guadeloupe). 400-1230 m. ATL.
Richardina spinicincta - Guadeloupe (first record for Lesser Antilles?), Karubenthos II 2015, field det. J. Poupin, st. CP4644, 28 June 2015, 15°46.96'N, 61°5.11'W, 898-835 m, MNHN-IU-2013-19177.
Comment: Overall Karubenthos specimen can be attributed to R. spinicincta a species described from eatern Atlantic (Bay of Biscay) and retrieved later by Goy (1982: 344) southwest of the Dry Tortugas, Florida, at a depth of 455-655 m. However the ventral margin of the rostrum is smooth whereas this part is distally dentate in R. spinicincta and also in Richardina fredericii Lo Bianco, 1903 a related species in the Mediterranean Sea. According to J. Goy that has examined the KARUBENTHOS specimen (pers. com. October 15, 2016), variation observed for sp. MNHN 19177 is in the range of variations observed for Richardina spinicincta. The genus Richardina includes currently three other species in the Pacific (Saito & Komatsu, 2009; Goy, 2015).
Comment(s) on data
In Richardina spinicincta A. Milne-Edwards, 1881 disto-vental margin has 2 spines as figured by Goy (1982, fig. 1a), Zariquiez Alvarez (1968, fig. 17c), and Kemp (1910, pl. 23, fig. 1); in Richardina fredericii, a related species in the Mediterranean Sea, there are also spines on disto-ventral margin of rostrum (Macpherson, 1978). Two Pacific species in Saito & Komatsu (2009) also have spines on this part.
