A review of the Tripterygion tripteronotus (Risso, 1810) complex, with a description of a new species from the Mediterranean Sea (Teleostei: Tripterygiidae)

We compared specimens of Tripterygion tripteronotus from 52 localities of the Mediterranean Sea and adjacent waters, using four gene sequences (12S rRNA, tRNA-valine, 16S rRNA and COI) and morphological characters. Two well-differentiated clades with a mean genetic divergence of 6.89 ± 0.73% were fo...

Two well-differentiated clades with a mean genetic divergence of 6.89 ± 0.73% were found with molecular data, indicating the existence of two different species. These two species have disjunctive geographic distribution areas without any molecular hybrid populations. Subtle but diagnostic morphological differences were also present between the two species. T. tripteronotus is restricted to the northern Mediterranean basin, from the NE coast of Spain to Greece and Turkey, including the islands of Malta and Cyprus. T. tartessicum n. sp. is geographically distributed along the southern coast of Spain, from Cape of La Nao to the Gulf of Cadiz, the Balearic Islands and northern Africa, from Morocco to Tunisia. According to molecular data, these two species could have diverged during the Pliocene glaciations 2.7-3.6 Mya.Se han estudiado especímenes de Tripterygion tripteronotus procedentes de 52 localidades mediterráneas y de aguas atlánticas adyacentes, utilizando cuatro genes mitocondriales distintos (12S rRNA, tRNA-valine, 16S rRNA y COI) así como varios caracteres morfológicos. Se han encontrado dos grupos molecularmente bien diferenciados, la divergencia genética media presente entre ambos es de un 6.89 ± 0.73%, lo que implica la presencia de dos especies distintas. Sus áreas de distribución están separadas y no se han encontrado poblaciones molecularmente híbridas. Además, se han encontrado pequeñas diferencias morfológicas que pueden ser utilizadas como caracteres diagnósticos entre las dos especies. T. tripteronotus se encuentra en la cuenca mediterránea norte, extendiéndose desde la costa NE de España hasta Grecia y Turquía, incluyendo las islas de Malta y Chipre. T. tartessicum n. sp. se extiende por la costa sur de España, desde Cabo La Nao hasta el Golfo de Cádiz, las islas Baleares y el norte de África, desde Marruecos a Túnez. De acuerdo con los datos moleculares obtenidos, ambas especies pudieron diverger durante las glaciaciones ocurridas en el Plioceno hace unos 2.7-3.6 m.a.This research was supported by a pre-doctoral fellowship from the Ministerio de Educación, Cultura y Deporte to J.C.
