Figure 6. Scanning electron photomicrographs show the scale microstructure in E. carinatus : upper head scales (A, 1000X; B, 3000X).
The scale microstructure of the head in E. rafsanjanicus andL. maynardi appear flat and smooth. At first glance, the scale structure in the two species looks alike, but thin longitudinal raised lines distinguishes the scale of E. rafsanjanicus from L. maynardi (Figure 7).
