    Two mitochondrial lineages of bats morphologically attributed to Hipposideros ruber have been shown to occur sympatrically in southeastern Senegal. We studied genetic diversity in these bats in the Niokolo Koba National Park using mitochondrial cytochrome b sequences to determine the taxonomic status of the two lineages, and included skull morphology for comparison. Detailed multidimensional analysis of skull dimensions indicated slight morphological differences between them. Exploration of peak frequency of the constant-frequency echolocation signals in a local population was not available for both lineages. Phylogenetic comparison with other West African representatives of H. aff. ruber revealed paraphyletic relationship of the two Senegalese forms, with the less abundant form from Senegal forming a monophyletic group with that from Benin. Based on genetic divergence and sympatric occurrence, the two Senegalese forms might represent cryptic species.
