Notes: This name was previously used (see Marschall, 1873, p. 402) in Crus- 

 tacea. It was merely an error for Asthenognathus and is not here consid- 

 ered to invalidate Reitter's usage. 

 ASTENUS Dejean, 1833, p. 65. 



Oenotype: Astenus angustatus (PaykuU) (Staphylinus) . 



Fixed by: Westwood, 1838a, p. 17, by subsequent designation, as "Staphylinus 



angustatus Fabricius." 

 Later citations : A. angustatus (PaykuU), by Shuckard, 1839, p. 102. A. brun- 

 neus Stephens ("= gracilis PaykuU"), by des Gozis, 1886, p. 14, neither one 

 originally included. A. immaculatus Stephens, by Lucas, 1920, p. 124, not 

 originally included. A. brunneus Stephens, by Blackwelder, 1939, p. 117. 

 A. angustatus (PaykuU), by Tottenham, 1940, p. 51; by Blackwelder, 1943, 

 p. 366. 

 Discussion : Dejean in 1833, Westwood in 1838, and Shuckard in 1839 credit 

 the name angustatus to Fabricius instead of PaykuU. The species referred 

 to is the same.

 Notes : This genus has generally been credited to Stephens, but that author 

 cites Dejean who validated the name by including several previously 

 established species.
