Comment: this species was collected during Karubenthos 2012 and 2015. The depth range is extented from 82-110 m to 14-367 m. It is sometimes considered as a juvenile of Solenolambrus typicus Stimpson, 1871 (Gore & Scotto, 1979; Felder et al., 2009, note 331) a species also present in Guadeloupe. The present specimens are tentatively separated from S. typicus based on presence of 6 low denticles on the posterior margin, between spine-tipped postero-lateral angles (margin smooth in S. typicus).

Comment(s) on data
See Remarks in Gore & Scotto (1979: 29) - Although we reluctantly maintain the validity of S. decemspinosus for the present, unless additional material of the species becomes available, we would be inclined to think it only a juvenile of S. typicus. Same remark is in Felder et al. (2009, note 331, As discussed by Gore and Scotto (1979), the description of this species, listed here as questionable (“?”), is possibly based upon an immature specimen of S. typicus.
[Based on 6 low denticles on postero margin, situated between spine-tipped postero-lateral angles. This could be a juvenile characters as discussed by Gore & Scotto (1979: 29) and the specimen could be a juvenile of S. typicus. It is interesting to remark that these authors have published a specimen of S. typicus from Guadeloupe (Fig. 11a-b), very close to Karubenthos II specimen, except for denticulations on postero-lateral margin],
