GENERIC NAMES OF THE FAMILY STAPHYLINIDAE 359 



STENOSIDOTUS Lynch— Continued 



Later citations : 8. acnescens Lj'nch, by Blackwelder, 1943, p. 209. 

 Synonyms: (See Hypostenus). 

 STENOSTETHUS (Agassiz, 1846, p. 352; Scudder, 1882b, p. 300; Schulze, 1937, 

 p. 3286; Neave, 1940, p. 298; nomen nudum). [See Stanosthethus, Stanos- 

 thetus, and Stenosthetus.] 

 STENOSTHETUS (Dahl, 1823, p. 17, nomen nudum) Griffith and Pidgeon, 1832, 

 p. 300. 

 Genotype: (Same as Pselaphus in the Pselaphidae). 



Fixed by: Griffith and Pidgeon, 1832, p. 300, through objective synonymy. 

 Synonyms: (See Pselaphus, in family Pselaphidae). 



Notes : This name was validated by citation in the synonymy of Pselaphus. 

 Although this was probably a zoological error, the name can never be 

 used for any other genus, and it is therefore not a staphylinid. It is 

 certain that Stenosthetus is the same as Stenostethus, Stanosthetus, and 

 Stanostethvs. However, this synonymy has never been listed, and the 

 three latter still stand as nomina nuda. 

 STENUS Latreille, 1796, p. 77, without species. 



Genotype : Stenus jiino (Paykull) iStaphylinns). 



Fixed ly: Paykull, 1800, p. 433, by being the first species placed in the 



genus. 

 Later citations : S. jimo (Paykull), by Fabricius, 1801, p. 602. S. liguttatus 

 (Linne), by Latreille, 1810, p. 427, not in first group. S. juno (Paykull), 

 by Curtis, 1827, pi. 164. S. bipustulatus (Linn6), by Westwood, 1838a, 

 p. 17, not in first group. S. juno (Paykull), by Shuckard, 1839, p. 101. 

 8. iiguttatus (Linng), by Cuvier, 1849, p. 185; by Thomson, 1859, p. 28; by 

 Lucas, 1920, p. 611 ; by Blackwelder, 1943, p. 208 ; by Tottenham, 1949b, p. 

 365 ; not in first group. 

 Discussion: Most citations of genotype for this genus have overlooked the 

 fact that when no species is definitely included in the original publication 

 of a genus, only those which are included in the first work to cite such 

 species are available for later selection. In the case of Stenus, most 

 writers have thought that the first group was that included by Fabricius in 

 1801. On that basis the designation by Latreille in 1810 would have been 

 valid. However, in 1800 Paykull included a single species. As long 

 as this is accepted as the first work to include species by name, that one 

 species must be accepted as the genotype by subsequent monotypy.
