Phylogenetic tree. Phylogram of vespertilionid bat species from Senegal (IVB S) and GenBank data with selected tribes indicated. A Bayesian phylogenetic tree based on the concatenated dataset of 6 mitochondrial and 2 nuclear genes (cytb + tRNAThr + 12S + tRNAVal + 16S + nd1 + rag1 + rag2; 5,665 bp; total n = 200) is presented. Nodes supports are indicated by posterior probabilities and/or bootstrap values resulting from ML analysis of the same dataset (BA values are left and ML values right of the hashes). Nodes, which were not supported with ML and were in different position than in BA, are indicated with “-”. Nodes are considered supported when Bayesian posterior probabilities are ≥0.95 and/or ML bootstrap proportions are ≥75%. The bar indicates genetic distance (the number of nucleotide substitutions per site). The map of Africa, shows the sampling localities of the five taxa considered to be cryptic in Senegal. The map shows the position of Senegal (S) and the countries, where the specimens from GenBank, used here for the genetic distance comparison, were sampled: SA – South Africa (Pipistrellus hesperidus), T – Tanzania (Scotoecus hirundo), K – Kenya (Neoromicia somalica, Nycticeinops schlieffenii, Neoromicia nana). The same symbols and colours are used to show the origin of the respective specimens in the phylogram.
