| Summary: | Synonymy of Solaster longoi Stampanato & Jangoux, 1993 New specimens of apparent Solaster longoi Stampanato & Jangoux, 1993 showing further size variation, including specimens from R= 1.8 to 6.4 cm were examined indicating that it is a synonym of Solaster regularis . The type series of S. longoi show a size range of R= 1.9 to 4.1 cm with the holotype showing R= 3.3 cm. Specimens with R=1.8 to 2.5 showed several overlapping characters between S. longoi and S. regularis as outlined in Stampanato & Jangoux (1993) and A.M. Clark (1962) indicating that S. longo i are small individuals of S. regularis . Specimens from USNM 1121461 for example showed 1 or 2 actinal intermediate spines as well as 2–3 furrow spines as outlined for type specimens for S. longoi , but also displayed 4 furrow and transverse subambulacral spines. One individual, USNM 1137343 at R= 6.4 cm showed 3 to 6 inferomarginal spines distally ( S. longoi ) but 10–11 spines proximally ( S. regularis ) as well as 5 to 8 spinelets on the paxillae which shows further overlap between S. longoi and S. regularis . These characters are also consistent with the presence of 8 arms and the occurrence of S. regularis in the Ross Sea suggesting that S. longoi shows no clear morphological distinction from S. regularis . Comments A summary of new specimens and published records of Solaster regularis confirms that it possesses a widely occurring high-latitude, including circus-polar distribution, including the South Atlantic (Clark & Downey 1992), the Indian Ocean (Kerguelen, Prince Edwards & Marion Island, unpublished data) (Stampanato & Jangoux 2004), the South Pacific, including Chile and the Ross Sea (Mutschke & Mah 2009, data presented herein). Specimen data also documents its known range from littoral to bathyal settings (2–2060 m). This species has been found in association with methane seep, chemosynthetic bivalve faunas off the Chilean coast (Sellanes et al . 2008). Occurrence South Pacific (Chile), South Atlantic (Brazil, Uruguay, ... |
