a Ratio of male tibia 1 / male tibia 2 in 1662 species (x-axis) of Pholcidae, taken from the taxonomic literature and sorted in each subfamily from smallest to largest values (Art. = Arteminae; Cai. = Caipirinae subfam. nov.; Mod. = Modisiminae; Nin. = Ninetinae; Pho. = Pholcinae; Phy. = Physocyclinae subfam. nov.; Sme. = Smeringopinae). Note that the values for the two new species of Caipirinae subfam. nov. described herein are among the lowest known in Pholcidae. b Scatter plot of the ratio male tibia 1 / male tibia 2 on a proxy of male leg length (tibia 1 length). Note that the lower left corner of the plot is almost entirely filled by Ninetinae and Caipirinae subfam. nov. Erroneous and dubious measurements reported in the literature were excluded (Table S6).
