ARNOLD tritineata w viridts â â singata -schreiben b) tiliguerta I' muratis- c I w meli$eltensis I' . sicula wagleriana â erhardii â pityusensis 0 graeca - derjugini â oxycephala. unisexualis Fig. 8. Known or assumed hybridization between species of Lacerta. c indicates hybrid- ization reported from captive animals, vv indicates hybridization assumed from morpho- logically intermediate animals caught in areas of sympatry. * indicates personal observation. For further explanation, see text. evidence of the characters usually employed that L. dugesii is a member of the subgenus Podarcis but its skeletal and hemipenial characteristics do not support such a relationship. Similarly the lizards now separated into the subgenera Archaeolacerta, Lacerta s. str. and Zootoca are all very similar in many features of their hemipenes and postcranial skeletons which may suggest a closer relation- ship than is usually acknowledged. This conflict of evidence makes it necessary to assess what relative taxonomic weight should be given to the various characters available. One factor that seems especially important in making this judgement is the comparative lability of the characters concerned. Obviously, beyond certain.
