GENERIC NAMES OF BUTTERFLIES 425 



SYRICTHUS Boisduval, 1840, Gen. Index meth, europ. Lep. : 35 (an incorrect Subsequent 



Spelling of Syrichtits Boisduval [1834]). 

 SYRMATIA Iliibner, [1819], Verz. bekannt. Schmett. (2) : 23. Type-species by selection by 



Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 274) : Limnas nyx Hiibner, [1817], 



Samml. exot. Schmett. 1 : pi. [33]. 



The taxon represented by the nominal species Limnas nyx is currently treated subjectively 



on taxonomic grounds as a form of the taxon represented by the older-established nominal 



species Papilio dorilas Cramer, [1775] (Uitl. Kapellen 1 (4) : 75, pi. 48, fig. C). 



SYRMOPTERA Karsch, 1895, Ent. Xachr. 21 : 308. Type-species by original designation : 

 Syrmoptera melanomitra Karsch, 1895, ibid., 21 : 308. 



SYSTASEA Edwards, June 1877, Canad. Ent. 9 : 120. Type-species through Section (i) 

 (replacement names) of Article 67 : Hesperia zampa Edwards, 1876, Trans, amer. ent. 

 Soc. 5 : 207. 



The name Systasea was introduced by Edwards as a replacement for the name Lintneria 

 Edwards, .March, 1877, which is invalid under the Law of Homonymy. 



The taxon represented by the nominal species Hesperia zampa is currently treated subject- 

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

 nominal species Leucochitonea pulverulenta Felder (I<), 1869 {Yerh. zool.-bot Ges. Wien 19 : 

 478)- 



SYSTASPES Weeks, 1905, ///. diurn. L9p. 1 : 20, 29, 116. Type-species by monotypy : 

 Antigonus corrosus Mabille, 1878, Petites Nouvelles ent. 2 : 196. 



Weeks used this name twice in the text (: 20, 29) and cited it also in the index. He said 

 nothing to indicate that it was 1 new name. Lindsey (1925, Ann. ent. Soc. Amer. 18 : 102) 

 reported that Weeks had stated {in Hit.) that he had received this name from Swinhoe. Lindsey 

 went on to say that Schaus had suggested that this generic name was an Incorrect Subsequent 

 Spelling of the name Systasea Edwards, 1877. Lindsey added that this view was supported 

 by the fact the sole species cited by Weeks was Antigonus corrosus Mabille ; from which it 

 may be inferred that he considered that this species was referable to the genus Systasea. It 

 may be observed, however that in the most recent treatment of the group — that by Evans, 

 T 953> (Cat. amer. Hesp. Brit. Mus. 3 : 158) it was placed in the genus Antigonus Hiibner, a 

 taxon which is however considered to be closely related taxonomically to Systasea. 



It is possible that the Schaus/Eindsey theory corresponds with the true origin of the name 

 Systaspes Weeks, but there is no evidence supporting that theory which would justify its 

 acceptance for nomenclatorial purposes. It follows therefore that the name Systaspes Weeks 

 must be treated as a nomenclatorially available name. From a practical point of view no 

 inconvenience ensures, for, as already explained, Antigonus corrosus Mabille, the type-genus, 

 is currently placed in the genus Antigonus. On this taxonomic view, therefore, the name 

 Systaspes Weeks is a junior subjective synonym of Antigonus Hiibner. 



SYSTOLE Mabille, [1886], in Grandidier, Hist. phys. nat. pol. Madagascar 18, Lep. 2 : pi. 51. 

 Type-species by monotypy : Hesperia amygdalis Mabille, 1877, Bull. zool. Soc. Fr. 1877 : 234, 

 nota. 



In the text Mabille cited other species, in addition to Hesperia amygdalis, but this was not 

 published until 1887 (ibid. 18 Lep. 1 : 33). This has no bearing on the question of the type- 

 species of this genus which had been determined by monotypy when in the previous year this 

 genus had been established on plate 51. Even if the plate and the text had been published 

 simultaneously, Hesperia amygdalis would still have been the type-species, for it was selected 

 as such by Watson in 1893 (Proc. zool. Soc. Lond. 1893 : 130). 



The name Systole Mabille is invalid for two reasons : first, because it is a junior homonym 

 of Systole Walker, 1832 (Ent. Mag. 1 (1) : 22) second, because it is a junior objective 

 synonym of Ploetzia Saalmuller, 1884. 

 SYTHON Geyer, [1832], in Hiibner, Ztr. z. Samml. exot. Schmett. 4 : 20 (an Incorrect Subse- 

 quent Spelling of Sithon Hiibner, [1819].
