Figures 91–104 in Reanalysis of Teruelius and Grosphus (Scorpiones Buthidae with descriptions of two new species

Figures 91–104. Light reflection properties of sternites VII and VI. Figures 91–102. Spatial distribution of intensity at 45° reflection angles of laser beam with 45° incidence to normal on sternites VII (odd numbered figures) and VI (even numbered figures) from Grosphus madagascariensis ♂ (91–92), Grosphus angulatus sp. n. ♀ (93–94), Lychas mucronatus, ♀ (95–96), Teruelius limbatus, ♀ (97–98), Teruelius flavopiceus, ♀ (99–100), and Teruelius ankarana, ♀ (101–102). Illumination source: 650 nm laser diode (650MDLC-5-1235), 5 mW, focused to 40 μm diameter spot on medial areas of sternites. Imaging device: Canon EOS 7D Mark II digital camera with 100 mm f/2.8 macro lens focused on translucent white diffuser screen intercepting reflected beams. TIFF files generated by linear RAW conversion. Scale: largest circle in each bounding box subtends 0.1022 sr. Figure 103. Horizontal bar chart comparing mean radii of dispersion of reflected beams in Figs. 91–102. Means obtained from pixel-normalized radial density functions computed by ImageJ 1.52a Radial Profile plugin, normalized to mean radius of specular reflection off a silver front surface mirror. Inset: sternites VI and VII from T. ankarana, ♀. Figure 104. Horizontal bar chart comparing mean intensities of reflected beams shown in Figs. 91–102. Mean intensities computed for pixels within central circle subtending 0.0637 sr, expressed as percentage mean intensity of specular reflection off a silver front surface mirror.
