We studied the systematic status of a form ofPollimyrusof the lower Kwando River that is flanked by the Okavango River, inhabited byPollimyrus castelnaui(Boulenger, 1911), and the Zambezi River, inhabited byPollimyrus marianneKramer et al., 2003. In morphology and electric organ discharges (EODs), the Kwando phenotype proved well differentiated from bothP. castelnauiandP. marianne. Sequence analysis of the cytbgene confirmed that the three forms or species form a monophyletic clade, withP. castelnauisister to the other two species. Genomic fingerprinting with ISSR-PCR confirmed differentiation of the Kwando form, that we recognize as a different species,P. cuandoensissp. nov., from its sister species,P. marianne. A considerable amount of EOD and morphological variation was revealed among samples ofP. cuandoensissp. nov. from four different locations on the lower Kwando River, possibly due to hybrid introgression. This seems an ideal system for testing theories of parapatric speciation. http://www.zoobank.org/urn:lsid:zoobank.org:pub:FB644B21-04F6-44F8-AEB6-8DC09268C17C
