Abstract

Abstract. Evolutionary parallelism complicates taxonomy of the bat genus Scotophilus. This implies the necessity for a careful examination of morphologically similar species. Robbins' — or “nutlet” — house bat Scotophilus nucella is an insufficiently known taxon of the African rainforest zone based on just a handful of recorded specimens previously included in the nut-coloured house bat S. nux. Because its phylogenetic relationship to S. nux and other congeneric species is unknown, it was assessed using analysis of DNA sequences of single mitochondrial and nuclear genes. Based on the mitochondrial cytochrome b sequences, S. nucella was placed in sister position to S. nux. A genetic divergence of 7.8–9.4 % between them supports the recognition of S. nucella as a distinct species. Analysis of partial sequences of the nuclear zinc finger protein gene on the Y-chromosome corroborated the sister relationship of S. nucella and S. nux, while showing sufficient differences to consider them as two species.
