Abstract(s)
The phylogenetic relationships of 27 north-eastern Atlantic and Mediterranean blennioids are analysed based on a
total of 1001 bp from a combined fragment of the 12S and 16S mitochondrial rDNA. The most relevant results with
implications in current blenniid taxonomy are: (1)
Lipophrys pholis
and
Lipophrys
(
=
Paralipophrys
)
trigloides
are
included in a well-supported clade that by the rule of precedence must be named
Lipophrys
; (2) the sister species of
this clade are not the remaining species of the genus
Lipophrys
but instead a monotypic genus comprising
Coryphoblennius
galerita
; (3) the smaller species of
Lipophrys
were recovered in another well-supported and independent
clade, which we propose to be recognized as
Microlipophrys
; (4) although some authors included the genera
Salaria
and
Lipophrys
in a single group we have never recovered such a relationship. Instead,
Salaria
is more closely related
to the genera
Scartella
and
Parablennius
; (5) the genus
Parablennius
, which was never recovered as a monophyletic
clade, is very diverse and may include several distinct lineages; (6) the relative position of
Aidablennius sphynx
casts
some doubts on the currently recognized relationships between the different blenniid tribes. Meristic, morphological,
behavioural and ecological characters support our results and are also discussed. The possible roles of the tropical
West African coast and the Mediterranean in the diversification of blenniids are discussed.
