The dorsal colour is vivid Magenta Orange with Ecclesiastic Purple iridescence ( Figure 1B View Figure 1 ). The scales are tile- or shovel-shaped with a uniformly toothed anterior margin. The length/width ratio of the tile-shaped scales is 3/1 (150/ 50 mm); the shovelshaped scales are shorter, the length/width ratio is 2/1 (100/ 50 mm). The dentation of the tile-shaped scales is more pronounced while the dentation of the shovel-shaped scales is far less prominent ( Figure 3A View Figure 3 ). We found three types of scale microstructures, which suggest a transformation series (see Discussion):
1. The longitudinal ridges are low, showing flutes on the longitudinal ridges, the cross ribs are straight. The space between the cross ribs is approximately 0.5 mm; but highly variable, there are larger and smaller ratios. The widely open microcells are rectangular with fragmented nanostructures, the trabeculae and the lower scale membrane can be clearly seen ( Figure 2B View Figure 2 ).
2. The longitudinal ridges are moderate with flutes, which with curved cross ribs form rectangular-shaped deeper-laying microcells. Spaces between cross ribs are approximately 0.5 mm, and regular. The microcell openings are circular and pepper-pot nanostructures can be seen through the microcell openings ( Figure 3C View Figure 3 ).
3. The longitudinal ridges with flutes are high and the cross ribs are v-shaped and form rectangular, very narrow, almost completely closed microcells with a single circular opening at the bottom. The spaces between the cross ribs are less than 0.1 mm; their sequence is regular. Pepper-pot nanostructures can be seen beneath the openings ( Figure 3D View Figure 3 ).
