Sexual size dimorphism within Hymenopodinae.
(a) Time calibrated phylogeny of Hymenopodinae with branch colours according to rates of SSD change (heat map in bottom left indicates rate values). A highly supported rate shift for increased SSD (red ellipse) indicated on branch 1 with shifts for increased proportional femoral leg lobe area on branches 2 and 3. Posterior probabilities (PP) greater than 99 (black circles) and below 75 (black squares) indicate support. Numbers adjacent to species name indicate corresponding photograph to the right. (b) Step plot of pronotum lengths for males (black) and females (red) with dashed horizontal lines highlighting taxa with SSD greater than 1.9, which correspond to the three species photographed to the right. (c) Scaled images of Hymenopodinae (numbers indicate species on phylogeny) for males and females with SSD ≥1.9 and ≤1.4 (specimen photographs by Rick Wherley).
