POLISTOMA Casey, 1893, p. 289. [Junior homonym of Polistoma Chiaje, 1837. 

 Not Gemminger and Harold, 1868. Synonym of Emplenota.] 

 Genotype: Polistoma crassicornis (Stephens) (Aleochara). 

 Fixed by : Casey, 1893, p. 289, through objective synonymy with Polystoma 



Stephens, of which crassicornis had already been fixed as genotype. 

 Later citations : P. maritima Casey, by Fenyes, 1918, p. 24. 

 Discussion: This name was proposed definitely as replacement for Poly- 

 stoma (1893), but in 1906 Casey referred to it as a typographical error. 

 The previous use of Polistoma by Gemminger and Harold for the same 

 genus was an error without nomenclatural standing. 

 Synonyms : ( See Emplenota ) .
