Fig. 1 in Evolution of hyperflexible joints in sticky prey capture appendages of harvestmen (Arachnida, Opiliones)
Fig. 1 Evolution of distal pedipalpal joints in harvestmen. Phylogenetic tree based on Schönhofer (2013) and Groh and Giribet (2014). The right schematic images of the joints between patella, tibia, and tarsus. Numbers below give the relative width of the joint (width of segment at the joint divided by highest width of the segment) and the range of movement (ROM). (Superscript number one) Reconstruction of ancestral states of ROM of the tibiotarsal joint with Mesquite V 3.04; (Superscript number 2) character traces of glandular setae following Wolff et al. (2016); Single asterisk in the p-t-joint of C. agilis, the pivot axis is tilted such that adduction-abduction movement is performed instead of flexion-extension (typical for Eupnoi); Double asterisks in the p-t- and t-t-joints of S. simoni are not uniaxial but perform rotational movements in addition to flexion-extension movements (number represents full range of movement)
