OLISTHAERUS Dejean, 1833, p. 69. 



Oenotype: Olisthaerus substriatus (Paykull) (StaphyUnus). 

 Fixed hy : Dejean, 1833, p. 69, by monotypy, as "suhstriatus Gyll." 

 Later citations: O. substriatus (Paykull), by Thomson, 1859, p. 48. 

 O. megacephalus (Zetterstedt), by Lucas, 1920, p. 455, not originally 

 included. 

 Discussion: This genus has generally been credited to Erichson or Heer, 

 in either of which cases the designation of megacephalus by Lucas would 

 have been acceptable except for the prior designation by Thomson. How- 

 ever, Dejean validated the genus by including a single previously described 

 species, making it monobasic.
