Differences in wing morphology are described for three Eurasian populations of Drosophila lummei. A truss network of wing characters was used to quantify wing size and shape for 149 individuals from Japan, Sweden and Russia. Sexual dimorphism in wing size and shape was not substantial, so the sexes were pooled and multivariate analyses conducted. Both principal components analysis and discriminant analysis of wing morphology revealed signi®cant differences among all geographic groups. These differences indicate that morphometric analysis of wing characters can reliably discriminate between geographic groups and accurately classify individuals of the three Drosophila lummei populations. Principal components analysis also revealed that characters occurring in the same section of the wing formed correlated suites which corresponded to morphologically and functionally distinct areas of the wing. This study is unique because it detects subtle morphological differences within a single species of fruit¯y across an intercontinental distribution.The results corroborate genetic studies in which geographic variation was found for inversion polymorphisms among spatially separated populations of Drosophila lummei.

The genus Pedioplanis reaches its northernmost limit in western Angola, where it is represented by three species, Pedioplanis benguelensis, P. haackei and P. huntleyi. The taxonomic status of P. benguelensis remains problematic, mainly due to the vague original description and the loss of the original type material. Here we provide a revision of the Angolan representatives of the genus, with the description of a new species, Pedioplanis serodioi sp. nov., from the lowlands of southwestern Angola. Phylogenetic analyses using a combination of mitochondrial (16S and ND2) and nuclear (RAG-1) markers, as well as morphological data, support the recognition of the new species. For purposes of nomenclatural stability, we designate a neotype for P. benguelensis and provide motivation to correct the spelling of the specific epithet to “benguelensis”. The clarification of the status of P. benguelensis and the description of a new species contribute to a better understanding of the taxonomy and biogeography of the genus Pedioplanis, as well as the general biogeographic context of southwestern Angola, adding to the growing evidence in favor of the recognition of this region as a hotspot of lizard diversity and endemism. An updated key to the genus is also provided.
