Area cladograms illustrating geographic components (areas of endemism) shared between Sibynomorphus and other taxa of western South America. "Austral South America" here refers to all of cis-Andean South America south of Amazonia; the exact area delimited varies somewhat in each case (see discussion and references in the text). Solid lines in the cladograms indicate shared geographic components. Dashed lines indicate one or more geographic components not present in Sibynomor- phus. (A) Geographic components in Sibynomorphus. Neither the monophyly of the genus itself nor its geographic components ("northern" and "southern" species groups) is strongly supported (see text). (B) Geographic components in the frog Ceratophrys (Leptodactylidae or Ceratophryidae). (C) Geographic components in the lizard Ctenoblepharys (Liolaemidae). (D) Geographic components in the lizard Microlophus and related lizard genera (Tropiduridae). uador/Peru taxon is most closely related to American taxa. For Ctenoblepharys (Fig. the Amazonian species, whereas in Micro- 45C), the area cladogram is identical with lophus (Fig. 45D), the Amazonian taxa are that of Sibynomorphus (, no Amazonian more closely related to the austral South component is present) except that species.
