GENERIC NAMES OF THE FAMILY STAPHYLINIDAE 279 



OSORIUS (Dejean, 1821, p. 24; Latreille, 1S25, p. 245; LePeletier and Serville, 

 1825, p. 470; Berthold, 1827, p. 332; nomen nudum) Latreille, 1829, p. 438, 

 without species. 



Oenotype : Osorius brasiliensis Gu6rin-M(5neville. 



Fixed by: Gu^rin-M^neville, 1830, pi. 9, by being the first species included 

 in the genus by name (subsequent monotypy) . 



Later citations: O. incisivrurus Latreille, by Cuvier, 1849, pi. 27. "0. tardus 

 Dejean," by Crotch, 1870, p. 236. 0. latipes (Gravenhorst) , by Blackwelder, 

 1943, p. 174. 



Discussion: Latreille (1829, p. 438), is the first author to mention species, 

 but he does not name them. There is some doubt of the date of Gu^rin- 

 M^neville, but it seems probable that plate 9 appeared before Perty (1830, 

 p. 30) , which is the next author to include species. It is not unlikely that 

 further uses of this name in the period from 1825 to 1830 will be discovered, 

 and the genotype may be changed thereby. The species listed in 1821 by 

 Dejean (tardus) is a nomen nudum at that date and until 1832. The 

 designation of O. tardus Dejean could be accepted through the objective 

 synonymy of tardus and hrasiliensis, but the author of tardus is Latreille 

 (1832, p. 86). Lucas (1920, p. 467) failed to make an unambiguous 

 designation. 



Synonyms : 



MOLOSOMA Say, 1830, p. 49. 



Variant spellings : 



OzoEius Duponchel, 1842, p. 11. 

 OTHIELLUS Casey, 1906, p. 423. 



Oenotype: Othiellus laeviusculus (Stephens) (OtJiius). 



Fixed by : Tottenham, 1939b, p. 229, by subsequent designation. 



Later citations : O. laeviusculus ( Stephens) , by Tottenham, 1949b, p. 371. 



Notes : This name must now be used for the old genus Othius, because of the 

 change in application of the latter name. 

 OTHIOUS [Error for Othius]. 

 OTHIUS Stephens, 1829a, p. 23. [Synonym of Gyrohypnus.] 



Oenotype: Othius fulgidus (PaykuU) (Staphylitius). 



Fixed by : Stephens, 1833, p. 258, by subsequent designation. 



Later citations: O. fulgidus (Paykull), by Westwood, 1838a, p. 16. 0. fulvi- 

 pennis (Fabricius), by Thomson, 1859, p. 26; by Casey, 1906, p. 423; not 

 originally included. O. fulgidus (Paykull), by Tottenham, 1939b, p. 236. 

 0. puncttilatus (Goeze) , by Tottenham, 1949b, p. 671, not originally included. 



Discussion : The designations of fulvipennis and punctulatus can be accepted 

 only through the subjective synonymy of either with fulgidus. Lucas 

 (1920, p. 468) failed to make an imambiguous designation. 



Synonymic homonyms : 



Othius Stephens, 1829b, p. 284. 



Synonyms : ( See Oyrohypnus ) . 



Variant spellings : 



Othious Fowler and Donisthorpe, 1913, p. 235. 



Notes : See Discussion and Notes under Oyrohypnus. The Othius fulgidus 

 (Paykull) of many authors is the same as Gauropterus fulgidus (Fabricius) 

 and does not belong in the same genus as laeviusculus Stephens 

 (= Othiellus). 

 OTYTELUS [Error for Oxytelus].
