Abstract: Evolution of three Canary Island Vespertilionid bat species, Pipistrellus kuhlii, Pipistrellus maderensis, and Hypsugo savii was studied by comparison of similar to1 kbp of mtDNA (from cytochrome b and 16S rRNA genes) between islands. mtDNA reveals that both P. kuhlii and P. maderensis exist in sympatry on Tenerife (and possibly other islands). Their morphological similarity explains why their co-occurrence had not been detected previously. Levels of sequence divergence are quite low within P. maderensis. Haplotypes were either identical or separated by less than or equal to 2 mutational steps on two of the islands (La Gomera and El Hierro). However there is sufficient between-island divergence between haplotypes from Tenerife, La Palma, and La Gomera/El Hierro to suggest that they could represent three evolutionary significant units (ESU). H. savii has an overlapping island distribution but a contrasting phylogeographical pattern. Most significantly, sequence divergence is greatest between La Gomera and El Hierro ( greater than or equal to 12 mutational steps) indicating colonization of the latter from the former sometime during the last similar to 1.2 Ma, with low subsequent gene flow. Unlike P. maderensis the El Hierro population alone appears to represent an ESU. The H. savii haplotypes detected in Gran Canaria and Tenerife are identical or separated by 1 mutational step.
