GENERIC NAMES OF BUTTERFLIES 467 



ZIPOETES Wood-Mason, 1881, /. asiat. Soc. Bengal, Pt II, 50 (No. 2) : 86 (an Unjustified 

 Emendation of Zipaetis Hewitson, [1863]). 



In introducing the emendation Zipoetes, Wood-Mason remarked in a footnote that either 

 the spelling Ziboetes or the spelling Zipaetes would have been correct, but not the spelling 

 Zipaetis. 



ZIPOETIS Bingham, 1905, Fauna Brit, hid., Butts, 1 : 104 (an Incorrect Subsequent Spelling 

 of Lipaetis Hewitson, [1863]). 



ZIZEERIA Chapman, 1910, Trans, ent. Soc. Lond. 1910 : 480, 482. Type-species by original 

 designation : Polyommatus karsandra Moore, 1865, Proc. zool. Soc. Lond. 1865 (2) : 505, 



pi. 31, fig. 7. 



ZIZERA .Mi »irc, [1881], Lep. Ceylon 1 (2) 178. Type-species . by original designation : 

 Papilio alsus [Denis & Schiffermiiller], 1775, Ankiindung [sic] eines syst. Werkes Schmett. 

 Wiener Gegend : 184. 



The taxon represented by the nominal species Papilio alsus [Denis & Schiffermiiller], 1775, 

 is currently treated subjectively on taxonomic grounds as being the same as that represented 

 by the nominal species Papilio minimus Fuessly, 1775 (Verz. bekannt. schweizerisch . Ins. : 31). 

 Until recently there existed no means by which to determine the relative precedence to be 

 accorded to these two names, each published in 1775. This was settled in 1958 when by its 

 Opinion 516 (Opin. int. Comm. zool. Nom. 19 : 1-44) the Commission ruled, inter alia, that 

 Precedence was to be given to the \erzeichniss of Fuessly over the Ankiindung of Denis & 

 Schiffermiiller. 



ZIZINA Chapman, 1910, Trans, ent. Soc. Lond. 1910 : 482. Type-species by original desig- 

 nation : Polyommatus labradus Godart, [1824], Ency. mith. 9 (Ins.) (2) : 680. 



ZIZULA Chapman, 1910, Trans, ent. Soc. Lond. 1910 : 483. Type-species by original desig- 

 nation : Lycaena gaika Trimen, 1862, Trans, ent. Soc. Lond. (3) 1 : 403. 



The taxon represented by the nominal species Lycaena gaika Trimen has been identified 

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

 established nominal species Papilio hylax Fabricius, 1775 (Syst. Ent. : 526). This identifica- 

 tion was established by Corbet in 1940 (Entomologist 73 : 276) after an examination of 

 Fabricius' surviving type. The disturbing feature of Corbet's discovery lies in the fact that 

 for over one hundred and thirty years the nominal species Papilio hylax Fabricius has been 

 misidentified with the species accepted as the type-species of the genus Pithecops Horsfield, 

 [1828]. In the note given under that generic name proposals have been put forward for 

 stabilizing the long-established application of the name Pithecops, one of these being that the 

 name hylax Fabricius, as published in the binomen Papilio hylax, be suppressed under the 

 Plenary Powers. On the adoption of this proposal the name Lycaena gaika Trimen will 

 become the oldest available name for the type-species of the present genus, that species thus 

 recovering the name habitually applied to it hitherto. 



ZOGRAPHETUS Watson, 1893, Proc. zool. Soc. Lond. 1893 : 72, 84. Type-species by 

 original designation : Isoteinon satwa de Niceville, 1883, /. asiat. Soc. Bengal, Pt II, 52 

 (No. 1) : 86, pi. 10, fig. 15 o*. 



As explained in the note on Gehenna Watson, 1893, that name, which was published on the 

 same date and in the same paper as that containing the name Zographetus, was given 

 precedence below Zographetus by a First Reviser choice made by Evans in 1949. 



ZONAGA Billberg, 1820, Enum. Ins. Mus. Billb. : 78. Type-species by monotypy : Papilio 

 biblis Fabricius, 1775, Syst. Ent. : 505. 



The name Zonaga Billberg is invalid, as it is a junior objective synonym of Biblis Fabricius, 

 1807. As explained in the note on that generic name, the name of its type-species (Papilio 

 biblis Fabricius) is invalid, as it is a junior homonym of Papilio biblis Drury, [1773], the 

 oldest available name subjectively applicable to the species here in question being Papilio 

 hyperia Cramer, [1779].
