ABSTRACT: In recent years many cryptic bat species have been unmasked by differences in their echolocation calls. The yellow house bat (/Scotophilus dinganii/) is 1 of 3 species of /Scotophilus /currently described in southern Africa and is distinguished from the other 2 species by its size and yellow venter. Here we use genetic, morphological, and echolocation call data to show the existence of a cryptic species. We found that /S. dinganii/ consists of 2 forms, one that uses a peak echolocation frequency of 44 kHz and the other a peak frequency of 33 kHz. Both forms have yellow venters. The 44-kHz phonic type is up to 15% smaller than the 33-kHz phonic type and differed genetically by an average cytochrome-b (/Cytb/) sequence divergence of 3.3%. Furthermore, combined phylogenetic analyses of /Cytb/ and control region sequences indicate that the 2 phonic types are reciprocally monophyletic, suggesting that they are sibling species.
