  1. Means with different superscripts at each site are significantly different from each other (one-way ANOVA followed by a Tukey test). In bold, we present statistically significant measurements for all three comparisons in Tukey’s pairwise test for differentiation of the species. Mean in millimeters
  2. TL total length, HL head length, XL thorax length, AL abdomen length, IO interocular distance, AO anteocular distance, PO postocular distance
