The lesser mouse-tailed bat Rhinopoma hardwickii Gray, 1831, of the bat family Rhinopomatidae had been traditonally regarded as broadly distributed throughout the dry and desert regions of the Old World. Recent molecular genetic data, however, showed the African and Middle Eastern populations as a separate species, R. cystops Thomas, 1903, while restricting R. hardwickii s.str. to the remaining Asian regions from Iran eastwards. Several individuals of Rhinopoma, tentatively assigned to R. hardwickii s.l. by external morphology, were captured in southeastern Senegal and northwestern Mauritania. Phylogenetic position of these specimens within Rhinopoma was inferred in order to confirm their taxonomic affiliation using mitochondrial cytochrome b sequences. Two closely related haplotypes clustered as a deeply divergent evolutionary lineage within an unresolved monophyletic group further comprising R. cystops from Morocco up to southern Arabia and R. hardwickii s.str. from Iran and India, differing 7.9–9.1% uncorrected genetic distance from these two lineages. This endemic West African lineage likely represents a remainder of an early colonisation of the African continent from Asia. Given the genetic differentiation from the other lineages of the R. hardwickii s.l. group, a separate species should be considered for this new lineage.
