Prosopocoilus motschulskii (Waterhouse, 1869)) are distributed in the flatland to low-altitude sub-forests of western Taiwan, China, and the main activity season of adult insects is April to July, with certain phototropism.
Males with high sand saw spades have thick and sharp downward curvatures in their large jaws, with 3-4 small toothed protrusions on the medial side.

The high sand saw shovel and the Japanese Yaeyama saw shovel are closely related species, and they are also relatively similar in terms of guanguan.
The female of the high sand saw spade is about 24–30 mm long, dark brown in color, covered with obvious markings on the back, and has a broad body, with an arched bulge in the side view, and an enlarged end of the posterior tibia.
