| revision of the western australian pebble-mimic dragon species-group (tympanocryptis cephalus: reptilia: agamidae). | recent work on species complexes of the pebble-mimic dragons of the australian genus tympanocryptis has greatly clarified evolutionary relationships among taxa and also indicated that species diversity has been severely underestimated. here we provide a morphological and molecular appraisal of variation in the t. cephalus species-group and find evidence for recognizing five species-level lineages from western australia. four species-level lineages are strongly supported with a combined mitochond ... | 2015 | 26624468 |
