我们形态学和遗传学研究了南部非洲电鱼Petrocephalus catostoma，或丘吉尔，和它的六个名义物种，其中五个syndromization（三个有效的亚种）。我们恢复synonymized种，并承认Petrocephalus tanensis（怀特黑德和格林伍德，1959年）从塔纳河在肯尼亚，也使用电器官放电。奥卡万戈三角洲（博茨瓦纳）居住着Petrocephalus okavangensis sp. nov.和Petrocephalus magnitrunci sp. nov.，我们确认赞比西河下游（莫桑比克）的Petrocephalus petersi sp. nov.和赞比西河上游（纳米比亚）的Petrocephalus longicapitis sp. nov.。赞比亚北方的卢富布河流域分布着长额岩首虫Petrocephaluslongianalissp. nov.，其中南部的丘吉尔，Petrocephaluswesselsi克雷默和货车derBank，2000证实了种内和种间分化。线粒体DNA的序列数据证实了两个新的西方和两个东方物种的分化，形成了相互的姐妹群。
We morphologically and genetically studied the southern African electric fish Petrocephalus catostoma, or churchill, and its six nominal species, five of which by synonymization (three valid subspecies). We reinstate the synonymized species, and recognize Petrocephalus tanensis (Whitehead and Greenwood, 1959) from the Tana River in Kenya, also using electric organ discharges. The Okavango delta (Botswana) is inhabited by Petrocephalus okavangensis sp. nov. and Petrocephalus magnitrunci sp. nov., and the Namibian Cunene River by Petrocephalus magnoculis sp. nov. We recognize Petrocephalus petersi sp. nov. for the Lower Zambezi River (Mozambique), and Petrocephalus longicapitis sp. nov. for the Upper Zambezi River (Namibia). The Lufubu River in Northern Zambia is inhabited by Petrocephalus longianalis sp. nov. For the southern churchill, Petrocephalus wesselsi Kramer and Van der Bank, 2000, we confirm intraspecific and interspecific differentiation. Sequence data from mitochondrial DNA confirm differentiation of two new western and two eastern species, forming mutual sister groups.
