Figure 37 in Etudes on iurids, II. Revision of genus Calchas Birula, 1899, with the description of two new species (Scorpiones: Iuridae)

Figure 37: Key morphometric ratio differences in species of Calchas based on 28 sets of measurements. Top. Metasomal segment V proportions (length/width) show that metasomal segment V is considerably more slender in C. nordmanni than in the other two species, exhibiting considerable standard error as well as absolute range separation. Differences in mean values between C. nordmanni and the other two species, male|female, is as follows: C. birulai = 24.2 %| 27.1 %, C. gruberi = 27.4 %|23.8 %. Bottom. Telson proportions (telson length / vesicle length) show that species C. nordmanni and C. birulai have a longer vesicle than that seen in C. gruberi. The mean value differences between C. gruberi and the other two species (combined) is 13.8 % male and 16.2 % female. Also of interest in both sets of ratios, we see that the differences between the genders across species are negligible.

Figure 33 in Etudes on iurids, II. Revision of genus Calchas Birula, 1899, with the description of two new species (Scorpiones: Iuridae)

Figure 33: Relative position of chelal trichobothrium it in Calchas based on its location with respect to the fixed finger length. Trichobothrium it mean position indicated by open circle based on 30 samples. Method of measurement: ff_LENG = fixed finger length, it_POS = it position. Histogram of morphometric ratio shows mean (vertical bar), minimum, maximum, and standard error (black rectangle) ranges. We see two significant it positional differences in these species: In C. birulai and C. nordmanni, trichobothrium it is approximately at finger midpoint or proximal, most exaggerated in C. birulai, whereas in C. gruberi trichobothrium it is considerably distal of finger midpoint.
