Rhinodontus Faust, 1890

Rhinodontus Faust, 1890: 455 (original description); Alonso-Zarazaga and Lyal 1999: 183 (catalogue); Borovec 2003: 32 (genus revision); Borovec 2009: 76 (check-list); Alonso-Zarazaga et al. 2017: 403 (catalogue).

Remarks.

The genus is well defined and distinguished by apex of protibiae strikingly enlarged laterally, armed with wide spines, epistome long, rostrum short and wide, distinctly enlarged before eyes and body wide and robust. It was described as monotypic by Faust (1890) and studied later by Voss (1967) and Borovec (2003). Rhinodontus currently 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.
