Examples of boxplots from male quantitative measurements used in species diagnosis (x-axis represents species). A, B, D are ratios: A carapace length/metatarsus III length B palpal tibia length/metatarsus III length D extent of scopulation on metatarsus IV C is carapace length (a proxy for body size), clearly showing the size differences between the miniature species and all other species (y-axis in mm). Additional boxplots can be viewed in Suppl. material 2.
