GENERIC NAMES OF THE FAMILY STAPHYLINIDAE 315 



PLESIOLINUS Bernhauer— Continued 

 Synonyms : ( See Platydracus) . 



Notes : This has previously been listed as a subgenus of Staphylinus. 

 PLESIOSIPALIA Bernhauer, 1943a, p. 173. 

 Genotype : Plesiosipalia arroici Bernhauer. 

 Fixed by : Bernhauer, 1943a, p. 173, by monotypy. 



Notes : This work has not been seen. The fixation may also have been by 

 original designation. 

 PLEUROTOBIA Casey, 1906, p. 273. [Synonym of Ditropalia.] 

 Genotype : Plewotobia sutnraUs Casey. 

 Fixed by : Fenyes, 1918, p. 24, by subsequent designation. 

 Synonyms : ( See Ditropalia ) . 

 PLOCHIONOCERUS Dejean, 1833, p. 64. 



Genotype: Plochionocerus violaceus (Olivier) (Staphylinus). 



Fixed by : Dejean, 1833, p. 64, by virtual monotypy. 



Discussion: Dejean listed tvpo species, but one of these was a nomen nudum. 



Synonyms : 



Stekculia Laporte, 1835, p. 118. [Isogenotypic] 

 Agbodes Nordmann, 1837a, p. 161. [Subgenus.] 

 Araeocnemus Nordmann, 1837a, p. 113. 

 Plociocerus Agassiz, 1846, p. 299. [Emendation.] 

 Callictenus Chevrolat, 1848b, p. 24. [Isogenotypic] 

 Variant spellings : 



Plociocebus Agassiz, 1846, p. 299. [Emendation.] 

 Notes : There seems to be no reason for not recognizing this Dejean name, 

 unless it were set aside under the Plenary Powers to save Plochionocerus 

 Sharp. The present genus is currently known under two names. 

 PLOCHIONOCERUS Sharp, 18S5, p. 471. [Junior homonym of Plochionocerus 

 Dejean, 1S33. Synonym of iSendrt.] 

 Genotype: Plochionocertis forinicarius (Laporte) {Sterculia) . 

 Fixed by : Sharp, 1885, p. 471, by original designation. 



Later citations: P. formicarius (Laporte) by Lucas, 1920, p. 526; by Black- 

 welder, 1943, p. 491. 

 Synonyms : ( See Renda) . 

 Variant spellings: 



Pi.O(;iONocHORUS Luederwaldt, 1917, p. 45.° 

 Ptochionoceeus Borgmeier, 1931, p. 360. 

 Notes : So long as Plochionocerus Dejean is recognized, this is a junior homo- 

 nym of it. This genus thus requires a new name, at least until the Plenary 

 Powers are invoked to save it. 

 PLOCIOCERUS Agassiz, 1846, p. 299. [Emendation of Plochionocerus Dejean.] 

 Genotype: Plociocerus violaceus (Olivier) (Staphylinus). 

 Fixed by : Agassiz, 1846, p. 299, through objective synonymy with Plochiono- 

 cerus Dejean, of which violaceus had already been fixed as genotype. 

 Synonyms: (See Plochionocerus Dejean). 

 ^ PLOCIOPTERUS Kraatz, 1857c, p. 539. 



• Genotype: Plociopterus fetialis (Erichson) (Staphylinus). 



Fixed by : Blackwelder, here, by subsequent designation. 

 Discussion: Lucas (1920, p. 526) failed to make an unambiguous designation. 

 Notes : Kraatz mentioned no species by name but cited the "Staphylinus Fam. 

 IV of Erichson," which contains five species.
