The name Crebeta Moore was published on the same date (and in the same work) as the name 

 Lopinga Moore, and in consequence the relative precedence to be accorded to these names 

 depends on the choice of the First Reviser. This choice was made by myself in 1964 (Annot. 

 lep. (3) : 78) when I chose the name Lopinga Moore to take precedence over the name Crebeta 

 Moore. 



CREMNA Doubleday, 1847, List Spec. lep. Ins. Brit. Mus. 2 : 14. Type-species by mono- 

 typy : Papilio actoris Cramer, [1776], Uitl. Kapellen 1 (8) : 146, pi. 93, fig. D $. 



Doubleday cited five nominal species as belonging to this genus, but four of these were 

 manuscript species at that time. Accordingly, Papilio actoris, the only published nominal 

 species cited, is, as stated above, the type-species by monotypy. 



The position of the nominal genus Cremna is complicated by the fact that Papilio actoris 

 Cramer, the type-species of this genus, is also the nominal type-species of the older-established 

 nominal genus Napaea Hiibner, [1819]. The last mentioned genus is however based upon 

 a misidentified type-species, for the species which Hiibner placed in the genus Napaea with the 

 specific name actoris is not, as he supposed, the same species as that to which Cramer had 

 applied that specific name. This was recognized as long ago as 1867 when Bates introduced 

 the name Cremna eucharila for the species misidentified by Hiibner as actoris eucharila being 

 in effect a nom. nov. for Hiibner's actoris. The present difficulty only arose when in 1937 on 

 the discovery of the Hiibner manuscripts, it was found that the nominal species Napaea 

 actoris Cramer, Hiibner nee Cramer was the type-species of Napaea Hiibner by monotypy. 

 The case of Napaea Hiibner is, as will be seen from the foregoing particulars, a clear instance of 

 a nominal genus based upon a misidentified type-species. As such, it is being submitted to 

 the Commission under Article 70(a) with a request that the species figured by Hiibner, 

 namely the nominal species Cremna eucharila Bates, be designated as the type-species of 

 Napaea Hiibner in place of the nominal species Papilio actoris Cramer, with which Hiibner 

 misidentified the species which he figured. 



Pending the outcome of the foregoing application, the existing practice is here maintained 

 in the interest of nomenclatorial stability in accordance with the provisions of Article 80. 

 Accordingly, although at present Cremna Doubleday (type-species : Papilio actoris Cramer) is 

 invalid as a junior objective synonym of Napaea Hiibner, [1819], it is here treated as an avail- 

 able name for the genus having Papilio actoris Cramer as type-species.

CRENIS Hiibner, 1821, Index exot. Lep. [2]. Type-species by monotypy : Crenis brylle 

 Hiibner, 1821, ibid. : [2]. 



The name Crenis brylle was introduced as a nom. nov. pro the name Nereis delila Hiibner, 

 [1813] (Samml. exot. Schmett. 1 : pi. [13]). This replacement was quite unnecessary and the 

 earlier name delila Hiibner is the valid name for this taxon. 



The taxon represented by the nominal species Nereis delila Hiibner is currently treated on 

 taxonomic grounds as representing a form of the taxon represented by the nominal species 

 Papilio doris Linnaeus, 1771, Mantissa Plant. 2 : 536).
