Study of morphological variation of northern Neotropical Ariidae reveals conservatism despite macrohabitat transitions

Table 4 Strength of convergent evolution based on the’ C-metrics’ including the calculated probability that the observed convergence exceeds what would be expected from randomly evolving lineages (P), and Procrustes distance (ProcD) between convergent taxa in Procrustes shape space

convergent taxa	C1	C2	C3 (= C2/L_tot.lineage)	C4 (= C2/L_tot.clade)	ProcD
A. jimenzi + S. herzbergii CLA	0.305 (P = 0.038)	0.023 (P = 0.041)	0.137 (P = 0.067)	0.006 (P = 0.061)	0.065
A. seemanni + S. herzbergii GOV	0.324 (P = 0.023)	0.018 (P = 0.087)	0.113 (P = 0.107)	0.005 (P = 0.108)	0.049

L_tot.lineage, L_tot.clade are defined as the total amount of change from the common ancestor of the convergent taxa leading to those taxa, and of the entire clade that contains the convergent taxa, respectively (see [61] for details). Values of C3 and C4 can be compared across datasets, whereas C1 and C2 can only be compared within the presented study
