Fig. 3. Bar charts showing frequencies (y-axis) of characters in each homoplasy class (x-axis) for each anatomy-based partition (i.e., HD, MP, … GN/ST). Bar heights indicate the proportion from the total number of characters in each anatomy-based partition that would fall into a particular homoplasy class as defined in the Bayesian analysis based on homoplasy scores. For example, the high frequency of ~0.4 in the 0.0 homoplasy class of leg characters (LG) shows that most characters from this anatomical region are perfectly congruent (i.e., zero homoplasy) with the implied weights parsimony tree. Abbreviations: H: mean homoplasy value across characters in a given partition; HD: head characters (except mouthparts); MP: mouthpart characters; MS: mesosomal characters (except legs and wings); LG: leg characters; WG: wing characters; MT: metasomal characters (except genitalia/sting); GN/ST: characters from the male genitalia and female sting apparatus.
