Ancestral state reconstruction and sampled tip states of coxo-lateropenital and coxo-stylar musculature across the Hymenoptera. Blue = Formicidae; yellow = Leptanillinae. Left and right topologies are identical. Node reconstructions not shown when all sampled descendants were scored as uncertain or inapplicable. See Supplementary Document 1 for explanation of inapplicability and additional notes. Cells represent characters. Cell fill represents character states: white = absent; black = present; diagonal lines = polymorphic absent/present; grey dots = uncertain; solid grey = inapplicable. Left tree: coxo-lateropenital muscles; cells in left-to-right order: 9clm1 (s), 9clm2 (qr), 9clm3 (p) , 9clm4 (o). Right tree: coxo-stylar muscles; cells in left-to-right order: 9csm1, 9cms2 (t), 9csm3 (u), 9csm4 (v).
