OULEUS Lindsey, 1925, Ann. ent. Soc. Amev. 18 : 95. Type-species by original designation : 

 Achlyodes fridericus Geyer, [1832], in Hiibner, Zutr. z. Samml. exot. Schmett. 4 : 9, pi. 

 106, figs 611, 612. 



Achlyodes fridericus was selected as the type-species of Achlyodes Hiibner by Scudder in 

 1875 (Proc. amer. Acad. Arts Sci., Boston 10 : 100) but that selection was invalid, Butler 

 (1870) having made a valid selection of a different species (Papilio busiris Cramer, [1779]) as 

 the type-species of that genus. The mistaken nature of the action remained undetected until 

 it was pointed out by Lindsey, who, realising that the correction so made left Achlyodes 

 fridericus without an available generic name, made good this deficiency by establishing the 

 nominal genus Ouleus for that species. 



OUROCNEMIS Baker, 1887, Trans, ent. Soc. Lond. 1887 : 176. Type-species by monotypy : 

 Anteros axiochus Hewitson, [1867], III. exot. Butts 4 : [77], pi. [42], figs 1,2. 



The taxon represented by the nominal species Anteros axiochus Hewitson is currently 

 treated subjectively on taxonomic grounds as being the same as that represented by the older- 

 established nominal species Papilio achytas Stoll, [1787], the type-species of the nominal genus 

 Aetkius Hiibner, [1819]. That name has however been completely neglected, while the name 

 Ourocnemis Baker has been in continuous use ever since it was published over seventy years 

 ago. Accordingly, as has already been explained, an application is being submitted to the 

 Commission for the suppression of the name Aethius Hiibner, (q.v.) thereby protecting the 

 name Ourocnemis Baker.

OXYPALPUS Holland, 1892, Ann. Mag. nat. Hist. (6) 10 : 293 et nota. Type-species by 



original designation : Pamphila ignita Mabille, 1877, Ann. Soc. ent. Fr. (5) 7, Bull. : xl. 



Holland stated that Oxypalpus was a manuscript name of Watson's. As will be seen from 



the immediately following note, Holland's publication of this name only narrowly anticipated 



its publication by Watson himself. 



The type-species of this genus is currently treated subjectively on taxonomic grounds as 

 being congeneric with the type-species (Teniorhinus watsoni Holland, 1892) of the genus 

 Teniorhinus Holland, 1892. The names Oxypalpus Holland and Teniorhinus Holland are thus 

 subjective synonyms of one another. As these names were published in the same paper and 

 on the same date, the relative precedence to be accorded to them depends upon the choice of 

 the First Reviser. This choice was made in 1937 (Cat. Afric. Hesp. Brit. Mus. : 96) by 

 Evans, who gave precedence to Teniorhinus Holland, while sinking the name Oxypalpus as a 

 junior synonym. 



OXYPALPUS Watson, 1893, Proc. zool. Soc. Lond. 1893 : 71, 78. Type-species by original 

 designation : Pamphila ignita Mabille, 1877, Ann. Soc. ent. Fr. (5) 7, Bull. : xl. 



This case is exactly similar to that of the name Osmodes discussed above. In each case 

 Watson distinguished in manuscript a new genus, giving it a new name ; he communicated 

 his conclusions to Holland who thereupon, in 1892, published the new name in question, 

 thereby anticipating Watson's publication of that name which did not take place until 

 January 1893. The name Oxypalpus Watson, 1893, is thus invalid, both as a junior homo- 

 nym of, and as a junior objective synonym of, Oxypalpus Holland, 1892.
