Multiple convergent events created a nominal widespread species: Triplophysa stoliczkae (Steindachner, 1866) (Cobitoidea: Nemacheilidae).

ABSTRACT:

Background

Triplophysa stoliczkae is the most widespread species in the genus Triplophysa and may have originated from morphological convergence. To understand the evolutionary history of T. stoliczkae, we employed a multilocus approach to investigate the phylogenetics and the morphological evolution of T. stoliczkae on the Qinghai-Tibetan Plateau.

Results

All phylogenetic analyses (two mitochondrial and five nuclear loci), a genealogical sorting index and species tree inferences suggested that T. stoliczkae consists of distinct lineages that were not closest relatives. The time estimation indicated that the divergence events between "T. stoliczkae" and other Triplophysa species occurred from approximately 0.10 to 4.51 Ma. The ancestral state analyses supported the independe
