Comment: this species has been collected during Karubenthos 2012 and 2015 with a new minimum depth range set at 23 m, instead of 91 m previously. Gore & Scotto (1979: 28) indicate spinose variations in this species and consider that Solenolambrus portoricensis Rathbun, 1924 from Puerto Rico and S. decemspinosus (also collected during Karubenthos, see comment under that species) are potentially conspecific.

Comment(s) on data
Solenolambrus typicus Stimpson, 1871 has two affiliated species, Solenolambrus portoricensis Rathbun, 1924 (known by unique type specimen in Porto Rico) and S. decemspinosus 'apparently known from only two specimens, the male holotype (Florida, 110 m), and a second male from Puerto Rico'. Considering variation within S. typicus it could be that the 3 species are co-specific (Gore & Scotto, 1979: 29 - Remarks: This species is apparently known from only two specimens, the male holotype, and a second male
from Puerto Rico. Rathbun (1925) noted that it was closely allied to Solenolambrus typicus. The differences between S. decemspinosus and S. typicus, noted by her in the description of S. decemspinosus, are similar to those we noted between juvenile and mature specimens of other parthenopids (e.g., shape of the anterolateral margin of the carapace, development of spination, and others). Furthermore, as we discussed under the species account for S. typicus, males of the latter species tend to be more spinose with sharply acute or spiny dorsal pyramidal protuberances, and with well-developed teeth or spines on the branchial ridge at the posterolateral margin, whereas females do not exhibit these features. In view of these facts, and because S. decemspinosus is known from only two small, male specimens, it seems possible that the species is only a juvenile form of S. typicus. The former species is known from only off northwest Florida and the northeastern Caribbean Sea and has not been collected since 1899. The latter species is widely distributed from North Carolina throughout the Caribbean Sea, and W. Pequegnat (1970) listed a single Gulf of Mexico
specimen from the continental shelf off Texas. 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.
