Abstract
Identification of taxonomical units underpins most biological endeavours ranging from accurate biodiversity estimates
to the effective management of sustainably harvested, protected or endangered species. Successful species
identification is now frequently based on a combination of approaches including morphometrics and DNA markers.
Sequencing of the mitochondrial COI gene is an established methodology with an international campaign directed
at barcoding all fishes. We employed COI sequencing alongside traditional taxonomic identification methods and
uncovered instances of deep intraspecific genetic divergences among flathead species. Sixty-five operational taxonomic
units (OTUs) were observed across the Indo-West Pacific from just 48 currently recognized species. The most
comprehensively sampled taxon, Platycephalus indicus, exhibited the highest levels of genetic diversity with eight
lineages separated by up to 16.37% genetic distance. Our results clearly indicate a thorough reappraisal of the current
taxonomy of P. indicus (and its three junior synonyms) is warranted in conjunction with detailed taxonomic work on
the other additional Platycephalidae OTUs detected by DNA barcoding.
