Its type specimen is no number, a skull, and it is a 3D body fossil. Its type locality is Aso, which is in a Langhian/Serravallian coastal shale in the Aoki Formation of Japan.

It was synonymized subjectively with Allodesmus kernensis by Mitchell (1968); it was recombined as Megagomphos sinanoensis by Barnes and Hirota (1995); it was recombined as Allodesmus sinanoensis by Kohno (1996), Kohno et al. (2007), Tonomori et al. (2018), Berta et al. (2018) and Boessenecker and Churchill (2018).
