Abstract:
We present a comprehensive checklist of cave-dwelling populations of Rhamdia from the Sierra de Zongolica (SdZ) in Veracruz, Mexico, including two new records, based on permanent and verifiable evidence in the form of voucher specimens. We use phylogenetic and phylogeographic analyses of voucher-derived comparative cytochrome b data to shed light on the evolutionary history of these populations. Our results, whilst preliminary, suggest that hypogean forms of Rhamdia from the SdZ are cave-adapted populations of the more widespread and epigean species R. laticauda. Keywords: Rhamdia zongolicensis; Rhamdia laticauda; troglomorphism; cave fishes
