Genus RHORUS Foerster 



Rhonis Foerster, 1868. Naturh. Ver. Rheinlande, Verb. 25: 195. 



Type-species: Tryphon mesoxanthiis Gravenhorst. By subsequent monotypy from 

 inclusion by Woldstedt, 1877. 

 Monoblastiis subg. Dolichoblastus Strobl, 1903 (1902) Naturw. Ver. f. Steiermark, Mitt. 39: 

 52. 



Type-species: Monoblastus (Dolichoblastus) flavopictus Strobl. Monotypic. 

 Cyphanza Cameron, 1909. Bombay Nat. Hist. Soc, Jour. 19: 723. 



Type-species: Cyphanza nigra Cameron. Monotypic. The name of the type-species 

 is preocc. in Rhonis by Provancher, 1883 and Ashmead, 1902. Townes' (1970) 

 proposal of the replacement name cameroni was apparently unnecessary because 

 he did not indicate that the synonymy of Monoblastus orientalis Cameron (1909, 

 p. 727) and Cyphanza nigra Cameron (1909, p. 723) by Townes, Townes, and 

 Gupta (1961) had been incorrect. Therefore, R. cameroni Townes should be 

 presumed to be a synonym of R. orientalis (Cameron). 



This is a large genus of Holarctic distribution. The tryphonine name Monoblastus was incor- 

 rectly applied to some species of Rhorus, particularly before World War II.
