( Figures 1A View Figure 1 , 2 View Figure 2 )
The dorsal colour is Burnt Orange without iridescence ( Figure 1A View Figure 1 ). The scales are tile- or shovel-shaped with a toothed anterior margin. The length/width ratio of tile-shaped scales is 3/ 1 (120/ 40 mm). The shovel-shaped scales are shorter and wider (length/width52/1, 80/ 40 mm). The dentation of the tile-shaped scales is deeper ( Figure 2A View Figure 2 ). We could not detect any qualitative difference between the microstructures of the two types. The longitudinal ridges are parallel and low, with flutes. The space (5length of the microcells) between the ridges is approximately 1 mm. Cross ribs are straight, their intervals are slightly irregular and less than 0.5 mm. The microcells are oblong or rectangular and widely open ( Figure 2B, C View Figure 2 ). The nanostructures are irregularly fragmented and sparse or lost with the trabeculae, and the reverse surface of the scale can be clearly seen at higher magnification ( Figure 2D View Figure 2 ).
