Resumo(s)
Molecular (partial mitochondrial 12S ribosomal DNA sequences), morphological and meristic analysis of Lepadogaster
lepadogaster lepadogaster, L. l. purpurea and L. zebrina were performed to investigate the relationships
between these taxa. On the western shore of mainland Portugal, where the two subspecies of L. lepadogaster occur
sympatrically, they differ in microhabitat preferences and their breeding seasons are largely out of phase. This information,
combined with data on distribution patterns, led to the following conclusions: Lepadogaster l. purpurea is
considered to be a valid species, L. purpurea (Bonnaterre, 1788), different from L. l. lepadogaster, now designated
L. lepadogaster (Bonnaterre, 1788). L. zebrina was found to be a synonym of L. lepadogaster. The two newly defined
species were found to be in sympatry at Madeira and the Canary islands, the Atlantic coast of the Iberian Peninsula,
and the Mediterranean at least as far as Genoa (Italy). Diagnostic characters and a list of synonyms are
provided. © 2002 The Linnean Society of London, Biological Journal of the Linnean Society, 2002, 76, 327–338.
