It was described as monotypic by Faust (1890)and studied later by Voss (1967)and Borovec (2003).  Rhinodontuscurrently contains five valid species from China and Mongolia ( Alonso-Zarazaga et al. 2017). Among material from IZCAS and ZIN we discovered specimens which add to our knowledge distribution of the species, which were previously known from only a limited number of specimens.
