GENERIC NAMES OF BUTTERFLIES 201 



It was when selecting the type-species for this genus that Westwood accidentally introduced 

 the Incorrect Subsequent Spelling Goniuris noted above. 



The name Goniarus Hiibner is invalid, as it is a junior objective synonym of Urbanns 

 Hiibner, [1807]. 



GONOPHLEBIA Felder (R.), June 1870, Petites Nonvelles ent. 2 (24) 9 15. Type-species by 

 monotypy : Globiceps paradoxa Felder (C.) & Felder (R.), 1869, loc. cit. 1 (8) : [31]. 



In introducing the name Gonophlebia in the paper cited above, Rudolf Felder gave a 

 figure of the species Globiceps paradoxa established jointly by his father Cajetan Felder and 

 himself in the previous year. In doing so, he cited the name of that species as Gonophlebia 

 (Globiceps) paradoxa. He gave no explanation of his action in citing the older name Globiceps 

 in brackets (parantheses) after his new name Gonophlebia, but it seems likely that he was 

 aware that the earlier name was invalid under the Law of Homonymy. This however, is no 

 more than a conjecture and it seems better therefore to treat this nominal genus as having had 

 its type-species determined by monotypy (Article 68 (c)) rather than through the replacement 

 procedure (Article 67(1)). 



The name Gonophlebia, though an available name, has been completely overlooked in the 

 literature, this genus being invariably known by the name Pseudopontia Plotz also published 

 in 1870. Unfortunately, the name Gonophlebia has priority over Pseudopontia, having 

 been published in June 1870, whereas the name Pseudopontia was not published until Septem- 

 ber of that year. Great confusion would result if it were necessary now to abandon the 

 long-established and universally accepted name Pseudopontia. To prevent this from taking 

 place, the Commission is being asked to suppress the name Gonophlebia for the purposes of the 

 Law of Priority, thus rendering the name Pseudopontia Plotz the oldest available name for the 

 present genus. In accordance with the provisions of Article 80 that in cases such as the 

 present existing usage is to be maintained, pending the publication of the Commission's 

 decision on the application, the name Pseudopontia Plotz is treated in the present work as the 

 oldest available name for this genus, the older name Gonophlebia Felder being treated as having 

 been invalidated in the manner proposed. 



GONOPTERA Billberg, 1820, Enum. Ins. Mus. Billb. : 76 (an Unjustified Emendation of 

 Gonepteryx [Leach], [1815I). 



There was a missprint in this name as actually published by Billberg, the name appearing 

 in the impossible form " Gonrptera ". 



Billberg stated that this was a manuscript name of Dalman's. He did not mention 

 Gonepteryx (Leach], but it is impossible to believe that Dalman and Billberg were both igno- 

 rant of this name published only five years earlier. Gonoptera Billberg is accordingly here 

 treated as an Unjustified Emendation of Gonepteryx [Leach].

GORGO Hiibner, [1819], Verz. bekannt. Schmett. (4) : 64. Type-species by selection by 

 Hemming 1933, Entomologist 66 : 198 : Papilio ceto Hiibner, [1803-1804], Samml. europ. 

 Schmett. : pi. Pap. 112, figs 578, 579. 



The taxon represented by the nominal species Papilio ceto Hiibner is currently treated 

 subjectively on taxonomic grounds as a subspecies of the taxon represented by the older- 

 established nominal species Papilio alberganus Prunner, 1798 (Lepid. pedemont. : 71).
