Fig. 1 a The chelicera of Dysdera (dorsal view) with measured cheliceral parameters. b, c The measurements used for the calculation of the concavity of the basal cheliceral segment. Abbreviations: BL – basal segment length, BW – section where the basal segment width was measured, CO – concavity of the frontal side of the basal cheliceral segment
