We used mitochondrial cytochrome oxidase I ( COI ) and the large ribosomal subunit ( 16 S ) genes to establish evolutionary relationships amongst species of Calyptraeotheres , evaluate their usefulness as DNA ‐barcoding genes, and assess molecular diversity at the population level within Calyptraeotheres garthi . B ayesian, maximum likelihood, and maximum parsimony phylogenies confirmed the monophyly of Calyptraeotheres, showing that the ancestor of C. garthi , Calyptraeotheres hernandezi , and Calyptraeotheres granti radiated after the formation of the P anamanian isthmus. This finding contradicts the austral/tropical hypothesis previously proposed based on morphological data. The COI and 16 S distance matrices supported separation of species as well as the genera, and corroborated that DNA barcoding is a useful tool and complements the classical taxonomy in P innotheridae. Phylogenetic and genetic distance analyses suggested that C. hernandezi is a junior synonym of C. garthi . Finally, C. garthi did not show a population structure across its distribution range, and showed a pattern consistent with a recent population expansion event that began 230–300 Kya. © 2013 The Linnean Society of London
