Figures 26–31 in Etudes on iurids, II. Revision of genus Calchas Birula, 1899, with the description of two new species (Scorpiones: Iuridae)

Figures 26–31: Subaculear setal pair (SSP) in genus Calchas, lateral view unless otherwise noted (note, only the SSP, VDSP, and DDSP setal pairs are shown). Conspicuous in these illustrations is the aculear placement of the SSP in species C. nordmanni and C. birulai. In C. gruberi, the SSP is located at the vesicle/aculeus juncture, common to most scorpions. 26. C. gruberi, sp. nov., female, Mamure Kalesi, Anamur, Turkey. 27. C. birulai, sp. nov., male holotype, Mardin, Turkey. 28. C. nordmanni, female, Tortum, Turkey. 29. C. nordmanni, male, Turkey. 30. C. nordmanni, female, Tortum, Turkey, viewed from the aculeus. 31. C. nordmanni, male, Tortum, Turkey, ventral view. VDSP = ventral distal setal pair, DDSP = dorsal distal setal pair.
