Vera & Pequeño (2001) compared the insular populations of Sicyases with those of continental Chile and supported the differentiation between insular and continental species. Vera & Pequeño (2001) followed De Buen (1960) in considering the insular species as S. hildebrandi rather than the earlier S. brevirostris. Sicyases brevirostris is considered by us as senior synonym of S. hildebrandi following Briggs’ (1955) conclusion based on examination of type material, rather than following De Buen’s doubt that Guichenot (1848) ever had specimens from the islands and his ascription of S. brevirostris as junior synonym of S. sanguineus. Briggs (1955) distinguished Sicyases brevirostris from S. sanguineus by a smaller head (>30% vs. <30% SL) and more anal fin rays (9 vs. 7-8). Vera & Pequeño’s (2001) study included an additional feature to distinguish both species: S. brevirostris with smooth skin and S. sanguineus with rugose skin except in the smallest specimens. Further research is needed, possibly at the molecular level, in order to determine whether these island populations are indeed distinct from their continental counterparts and if there has been any dispersal.
