Resumen:
A morphological study of eight species of Paralichthys, two species of Hippoglossina, and Lioglos
sina tetrophthalma, has revealed head lateralline canal topography differences of taxonomic value. In species
of Paralichthys, segment of the supraorbital canal in nasale of the blind side is connected with other canals
and canaliculi are ramified, whereas in species of Hippoglossina this segment is not connected and canaliculi
are not ramified. These different character states corroborate the generic distinction between ParalichthysParalichthys, two species of Hippoglossina, and Lioglos

Paralichthys until new morphological or molecular data are obtained. Paralichthys species vary in the degree
of ramification of canaliculi, presence or absence of infraorbital canal segment in the lacrimale of the ocular
side and posterior line of CST. Differences in lateralline canal topography of H. macrops and H. bollmaniuntil new morphological or molecular data are obtained. Paralichthys species vary in the degree
