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.
