1996. The evolution of locomotor morphology in Rhoptropus (Squamata: Gekkonidae): Functional and phylogenetic considerations. African Journal of Herpetology 45 (1) 8-30
… differences in the scaling relationships among the five Namibian species of the genus Rhoptropus. R. afer differs from all other taxa in y-intercept and size of ordinate variable at … reflecting functional constraint imposed by the hyperextensive scansorial system of the toes. Rhoptropus afer also typically has one fewer presacral vertebra than its congeners. There is no evidence that these features of R. afer are shared by its sister taxon, R. bradfieldi. It therefore seems likely that R. afer has evolved these locomotor characteristics, …
