Phylogenetic affinities of the fossil elapids Naja romani and Naja antiqua (Serpentes: Elapidae)


The genus Naja Laurenti, 1768 comprises 32 extant species of venomous snakes, commonly known as "cobras", allocated in four distinct lineages (Wüster et al., 2007, Mol. Phyl. Evol. 45:437–453): the Asian spitting-cobras (11 species, subgenus Naja), the African spittingcobras (seven species, subgenus Afronaja), the African non-spitting open area clade (six species, subgenus Uraeus) and the African nonspitting forest clade (seven species, subgenus Boulengerina). In recent years, the diversity of the genus has grown considerably, mainly given to taxonomic revisions based on new molecular analyses and new discoveries in the field. Furthermore, while the taxonomy of the genus is now considered stable, its evolutionary history remains poorly understood, especially within the known lineages. Apart from the extant species, the genus Naja also presents a rich fossil record that spans from the Early/Middle Miocene to the Late Pliocene in Africa and Europe. This fossil record has been studied in the past, with important remarks on their distribution throughout the European continent (Bachmayer, F. & Szyndlar, Z., 1985, Ann. Naturhist. Mus. Wien, 87:79–100; Szyndlar, Z. & Rage, J. C., 1990, Amphibia-Reptilia 11:385–400; Szyndlar, Z. & Zerova, G. A., 1990, Ann. Naturhist. Mus. Wien 91A:53–61). Szyndlar & Rage (1990) provided an osteological description of the genus based on both extant and extinct species, in an important contribution showing their geographic distribution. However, no attempts have been made to conduct a broader phylogenetic analysis until then. Here, we present the first attempt to elucidate the phylogenetic history of the genus, with a morphological analysis that includes 26 of the 32 extant species along with key-fossil taxa from the Miocene Naja antiqua and Naja romani) and the Pliocene (Naja depereti).
