A new species of Parapercis
(Teleostei: Pinguipedidae) from the Solomon Islands
Gerald R. Allen & Mark V.
A new species of pinguipedid
fish, Parapercis binotata, is described from
the Solomon Islands on the basis of six adult specimens,
46.5-56.5.5 mm SL. The new taxon belongs to the
Parapercis cylindrica complex, which
contains five other western Pacific Ocean species:
P. australis, P. cylindrica, P. haackei, P. lineopunctata,
and P. snyderi. It is most similar to P.
lineopunctata from the East Indian Archipelago,
but adult males are clearly distinguished by the presence
of two short black bands, one on the cheek and another
on the lower pectoral fin. Although lacking these
markings, females differ from those of P. lineopunctata
by the presence of a curved black band below the
eye. The only known habitat of the new species consists
of a nearly enclosed lagoon in 4-8 m depth. Analyses
of the mtDNA barcode marker COI sequences
for the P. cylindrica species complex show
exceptionally deep divergences between most species,
about 15-20% divergence between all but one pair
of species, with P. binotata 14.52% different
from its nearest relative, P. lineopunctata.
