Delimit Tigertooth Croakers and
Describe a New Species from the Western Arabian Gulf Using Integrative
Arabian Gulf is a marine region with numerous
potential new fish species for lack of modern taxonomic examination and
tigertooth croakers (Teleost, genus Otolithes)
have been found to have potential new species. We applied analyses on
genetic, morphology, and otolith shape data of Otolithes specimens collected from
the western Arabian Gulf and found one lineage with supports of all
lines of evidence which is named Otolithes
arabicus. This new species can be identified from other congeric
by having a truncate caudal fin margin and three black spots on the
second dorsal fin.
Fresh specimen of Otolithes sp. West Indian Ocean II Group type A (WIO IIA) and type B (WIO IIB) ), and Otolithes arabicus (WA) and the posterior part of the second dorsal fin, respectively. Scale bar = 5 cm.
