http://zoobank.org/ 36F889D1-2E27-40BB-95B9-7619031A223E

Type species. Eurygona eugeon Hewitson, 1856 .

Definition. This taxon is sister to the clade formed by Euselasia Hübner, [1819] ( Euselasia gelaena Hübner, [1819] , which is Papilio gelon Stoll, 1787 ) and Maculasia gen. n. and is prominently distinct from it genetically (Fig. 15 purple); hence it is a new genus. It is distinguished from its relatives by its inverted-drop shaped hindwing with extended anal lobe, as well as by its solid-brown color above and lack of eyespots below, fringes dark, legs yellow; and the following combination of nuclear genomic characters: cne 1999.2.1:C203A, cne 1015.3.2:T555C, cne2803.19.1:G88A, cne5471.1.1:T261C, and cne703.2.8:A1414C.

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: Euge [on] + [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 and Euselasia brevicauda Lathy, 1926 .

Parent taxon. Subfamily Euselasiinae Kirby, 1871 .
