synonym of one of the nominal species accepted by that author as representing a taxonomically 

 valid species. These doubts were removed in the present revised text of the Code which 

 provides (Article 69(a) (i)) that a nominal species included in a genus in the foregoing manner 

 is to be treated as being eligible for selection as the type-species by a subsequent author. 



TRIARIIA Verity, 1953, Le Farfalle diurn. d' Italia 5 : 186. Type-species by original designa- 

 tion : Papilio triarius Prunner, 1798, Lepid. pedemont. : 70. 



TRICHIOLAUS Aurivillius, 1898, K. svenska VetenskAkad. Handl., Stockholm 31 (No. 5) : 

 29, 317. Type-species by monotypy : Hypolycaena mermeros Mabille, 1878, Bull. 

 Soc. zool. Fr. 3 : 82. 



Aurivillius cited a second species (Iolaus argentarius Butler), but he placed this name as a 

 synonym of Hypolycaena mermeros Mabille. Under Article 68(c) of the current (revised) Code 

 the citation of such a synonym does not detract from the monotypical status of a genus.

 monotypy : Papilio theanus Cramer, [1777], Uitl. Kapellen 2 (12) : 65, pi. 139, fig. F.

 original designation : Tricosemeia subolivescens Holland, 1892, ibid. (6) 10 : 294. 



The taxon represented by the nominal species Tricosemeia subolivescens Holland is currently 

 treated subjectively on taxonomic grounds as being a subspecies of the taxon represented by 

 the older-established nominal species Ceratrichia tetrastigma Mabille, 1891 {Ann. Soc. ent. 

 Beige 35, Bull. C. R. : lxv). 



TRIFURCULA Staudinger, 1894, Iris 7 : 56. Type-species by monotypy : Trifurcula 

 huanaco Staudinger, 1894, ibid. 7 : 56, pi. 1, figs 7, 16, 17. 



The name Trifurcula Staudinger is invalid under the Law of Homonymy, being a junior 

 homonym (a) of Trifurcula Stainton, 1846 (Syst. Cat. Brit. Tin. : 30) and (b) of Trifurcula 

 Zeller, 1848 (Linnaea Entom. 3 : 330). It has been replaced by the name Piercolias Grote, 

 1903.

 by selection by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 286) : Papilio nero 

 Fabricius, 1793, Ent. syst. 3 (1) : 153. 



The name Trigonia Geyer is invalid, as it is a junior homonym of Trigonia Brugiere, 1789 

 (Ency. mith., Vers (1) : xiv).

TRIOPADES Hiibner, [1819], Verz. bekannt. Schmett. (5) : 73. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 286) : Papilio eupalemon Stoll, 

 [1781], in Cramer, Uitl. Kapellen 4 (31) : 146, pi. 366, fig. A. 



Stoll considered that his Papilio eupalemon was a Lycaenid butterfly of the " Plebius 

 Ruralis " Section of the genus Papilio and a similar view was taken by Hiibner. Kirby in 

 1871 (Syn. Cat. diurn. Lep. : 526) placed this species in the Hesperiids. Scudder (1875, loc. 

 cit.) pointed out that Stoll's species was not a butterfly.
