Remarks

There are three species in the type series for E. variabilis comb. nov., which include a single paratype and 10 cotypes. The paratype of E. variabilis shows similarity with E. acuta sens. lat., but further research is necessary to confirm if they are the same species and to revise morphologically similar species of Eocanthecona across the Indo-Pacific region. The cotypes of E. variablis are different species from the paratype and include a mix of Eocanthecona ( cf. vollenhoveni : RMNH.INS.1093148, RMNH. INS.109314850 to -109314852, RMNH.INS.109314854 to -109314855) and Cantheconidea mitis (RMNH.INS.1093149, -1093153, -1093156, RMNH.INS.1092852). Consequently, the C. variabilis cotypes are no longer considered E. variabilis . The two illustrations of C. variabilis from the original description do not match the appearance of the paratype, namely the paratype has spinose rather than the illustrated blunt humeri ( Vollenhoven 1868: pl. 1 figs 7–8). We suspect the illustrations were based on cotypes rather than the paratype.
