GENERIC NAMES OF BUTTERFLIES 141 



to the fact that for long there existed no rules for determining what species should be regarded 

 as being eligible for designation as the type-species of a genus established without citation of 

 nominal species and partly also to a reluctance, on the part of those who believed that 

 Fabricius had in mind the species Papilio danis Cramer when he established this genus, to 

 accept tautonymy between generic and specific names. In consequence the name Thyso- 

 notis Hiibner, [1819] was used by various authors for Papilio danis Cramer, it being the type- 

 species of that genus, but in more recent times the name Danis Fabricius has come into use, 

 though not completely replacing its junior objective synonym Thysonotis. 



DANISEPA Moore, 1883, Proc. zool. Soc. Lond. 1883 : 296. Type-species by original designa- 

 tion : Papilio radamanthus [sic] Fabricius, 1793, Ent. syst. 3 (1) : 42. 



The taxon represented by the nominal species Papilio radamanthus is currently treated 

 subjectively on taxonomic grounds as that represented by the nominal species Papilio 

 diocletianus Fabricius, 1793, ibid. 3 (1) : 40. As these names were published in the same work 

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

 made by the First Reviser. This appears to have been Doubleday who in 1847, Gen. diurn. 

 Lep. (1) : 88 accepted the specific name radamanthus, sinking diocletianus as a junior synonym. 

 The specific name radamanthus Fabricius, 1793, is therefore the oldest available name for the 

 present taxon. 



DANISEPPA Fruhstorfer, [1910], in Seitz, Grossschmett. Erde 9 : 261 (an Incorrect Subsequent 

 Spelling of Danisepa Moore, 1883). 



DAPIDODIGMA Karsch, 1895, Ent. Nachr. 21 : 310. Type-species by original designation : 

 Papilio liger Cramer, [1779], Uitl. Kapellen 3 (22) : 109, pi. 254, figs E, F. 



DAPTONOURA Butler, 1869, Cat. diurn. Lep. Fabricius : 209. Type-species by original 

 designation : Papilio lycimnia Cramer, [1777], Uitl. Kapellen 2 (9) : 13, pi. 105, figs E, F. 



DARASANA Moore, 1884, /. asiat. Soc. Bengal, Ft II, 53 (1) : 42. Type-species by original 

 designation : Amblypodia perimuta Moore, 1857, in Horsfield & Moore, Cat. lep. Iu\. 

 Mus. East India Coy (1) : 42. 



DARATVS Lindsey, 1925, Ann. ent. Soc. Amer. 18 : 84. Type-species through Section (i) 

 (replacement names) of Article 67 : Choristoneura apicalis Mabille, [1890], Bull. Soc. ent. 

 Fr. 1889 : clvi. 



Lindsey's designation of the above species was unnecessary and indeed invalid, because, as 

 a substitute name, Daratus takes automatically as its type-species the species [Choristoneura 

 apicalis) which is the type-species of the genus replaced, th.it is, the type-species of Choristo- 

 neura Mabille, [1890]. 



As explained in the note on Choristoneura, the taxon represented by the nominal species 

 Choristoneura apicalis is currently regarded subjectively on taxonomic grounds as being the 

 same as that represented by the older-established nominal species Astictopterus johnstonii 

 Butler, 1887. 



DARDARINA Evans, 1937, Revista Ent., Rio de J. 7 (1) : 88. Type-species by original 

 designation : Cyclopides dardaris Hewitson, 1877, Ann. Mag. nat. Hist. (4) 20 : 328. 



DARPA Moore, [1866], Proc. zool. Soc. Lond. 1865 (3) : 781. Type-species by monotypy : 

 Darpa hanria Moore, [1866], ibid. 1965 (3) : 781, pi. 42, fig. 2. 



DASYOMMA Felder (C.) & Felder (R.), i860, Wien. ent. Monats. 4 : 401. Type-species by 

 monotypy : Dasyomma fuscum Felder (C.) & Felder (R.), i860, ibid. 4 : 401. 



This name is invalid, as it is a junior homonym of Dasyomma Macquart, 1841 {Mim. Soc. 

 Set. Lille 1840 : 309). It has been replaced by the name Mydosuena Moore, 1880. 



DASYOPHTHALMA Westwood, [1851], in Doubleday, Gen. diurn. Lep. (2) : 343. Type- 

 species by selection by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 155) : Morpho 

 rusina Godart, [1824], Ency. mitli. 9 (Ins.) (2) : 451.
