| disentangling the pelomedusa complex using type specimens and historical dna (testudines: pelomedusidae). | recent research has shown that the helmeted terrapin (pelomedusa subrufa), a species that occurs throughout sub-saharan africa, in madagascar and the southwestern arabian peninsula, consists of several deeply divergent genetic lineages. here we examine all nominal taxa currently synonymized with pelomedusa subrufa (bonnaterre, 1789) and provide mitochondrial dna sequences of type specimens or topotypic material for most taxa. lectotypes are designated for testudo galeata schoepff, 1792, pentonyx ... | 2014 | 24870495 |
