Eurylasia Grishin, new genus

http://zoobank.org/ 44399705-A1CF-43AF-B35E-F510E964BDE0

Type species. Eurygona euryone Hewitson, 1856 .

Definition. Currently within Euselasia Hübner, [1819] (type species Euselasia gelaena Hübner, [1819] , which is Papilio gelon Stoll, 1787 ) but is not monophyletic with it (Fig. 15 pink). Instead, an independent prominent lineage in the same clade with and of the same rank as Methone Doubleday, 1847 (type species Papilio cecilia Cramer, 1777 ) (Fig. 15 brown, gray and red), hence is a new genus. It is diagnosed by its distal ⅖ of hindwing dusted pale-yellow below, large round marginal eyespot in the middle of it, and either large eyespot in the middle by forewing margin below or diagonal orange patch on forewing above. The hindwing tornus is pale above in some species. The following combination of nuclear genomic characters is diagnostic: cne9878.8.1:C146A, cne178.3.20:C595T, cne178.3.20:T596C, cne7676.26.2: T31C, and cne5931.2.1:A478G.

Etymology. The name is a feminine noun in the nominative singular formed as a fusion of the type species name and its former genus name: Eury [one] + [Euse] lasia to keep the word at 9 letters, which is the number of letters in Euselasia and the number of genera Euselasia is being split into.

Species included. The type species, Eurygona effima Hewitson, 1869 , Euselasia thusnelda Möschler, 1883 , and Eurygona eunaeus Hewitson, 1855 .

Parent taxon. Subfamily Euselasiinae Kirby, 1871 .
