VERA S., Rodrigo  and  PEQUENO R., Germán. Comparison of meristics and morfometrics character among clingfishes of the genus Sicyases from Juan Fernández archipelago, Valparaíso and Valdivia, Chile (Osteichthyes: Gobiesocidae). Investig. mar. [online]. 2001, vol.29, n.2, pp.3-14. ISSN 0717-7178.

The results ratify the existence of two species; Sicyases hildebrandi (Schultz, 1944) in the Juan Fernandez archipelago and S. sanguineus (Müller and Troschel, 1843) in the continental coastline of Chile. The specimens from Valdivia showed an overlapped patron, compared to insular specimens and as well as those from Valparaíso; however because they are from the continental coastline are supposedly in a geographical continuity and hence, must belong to the same species, Sicyases sanguineus. The new set of characteristics and the geographic isolation supports the redefinition of S. hildebrandi as the only species of the genus in Juan Fernandez archipelago and a new taxonomic key to recognize the species is presented

Keywords : clingfishes; Sicyases; taxonomy; Juan Fernández archipelago; Chile.
