摘要

Based on molecular, morphological and field data, the status and zoogeography of the taxa of the Psammophissibilans group north of 12°S are reviewed. Molecular data including sequences from 20 of the 22 described species knownto occur north of 12°S suggest that P. sibilans distribution is restricted to northeastern Africa, from Egypt to Ethiopia. Populationsfrom West Africa are described as a new species, P. afroccidentalis sp. nov., and those from Chad, Cameroon andCentral African Republic are assigned to P. rukwae which is also distributed from Tanzania to Ethiopia. Molecular dataindicate the occurrence within this complex of three additional cryptic species in the Horn of Africa. Populations previouslyassigned to P. phillipsi in Central Africa north, south and east of the Congo forest block are assigned to P. mossambicusand the status of P. occidentalis is discussed. P. phillipsi is restricted to West Africa, with P. irregularis as junior synonym.
