Fig. 50 in Phylogeny, Taxonomic Revision, And Character Evolution Of The Genera Chiasmocleis And Syncope (Anura, Microhylidae) In Amazonia, With Descriptions Of Three New Species

Fig. 50. Optimization of absence (gray) and presence (black) of the femoral line in Chiasmocleis. Four equally parsimonious alternative explanations, with four steps each. Scenario (A) shows a single appearance of the femoral line, with three reversals; scenarios (B) and (C) depicts alternative scenarios, involving appearances and reversals to absence; scenario (D) postulates four independent appearances of the femoral line. Taxonomy updated to the one proposed in the present work. Chiasmocleis devriesi is nested within C. anatipes and is not shown.
