Type species. Syrichthus [sic] festiva Erichson, [1849].

Definition. A sister genus of Sostrata Godman and Salvin, 1895 (Type species. Leucochitonea scintillans Mabille, 1876 , which is treated as a junior subjective synonym of Sostrata bifasciata (Ménétriés, 1829)) , where these species were placed before ( Fig. 6 ). Keys to E.42.1a in Evans (1953). Distinguished from Sostrata by blue ventral hindwing, broader wings and in male genitalia by longer harpe, clearly separated from the rest of valva. In DNA, a combination of the following base pairs is diagnostic: aly276665.9.3:C95G, aly923.23.1:G274A, aly 2790.3.6:A367C, aly923.23.1:T688G, aly2101.22.7:A31C.

Etymology. The name is a feminine noun in the nominative singular, given for the type species and for the festive looks that distinguish this genus from Sostrata .

Species included. The type species, Leucochitonea cronion C and R. Felder, 1867, Pythonides caerulans Mabille and Boullet, 1917 , Pythonides adamantinus Mabille, 1898 , Sostrata grippa Evans, 1953 , and Sostrata jinna Evans, 1953 .

Parent taxon. Subtribe Erynnina Brues and Carpenter, 1932.

Comments. Although this genus does not disrupt monophyly of the former concept of Sostrata that included these species, genetic distance between these sister genera is not less than that between Potamanaxas and Anaxas , gen. n., or between Mylon and Anastrus . This comparatively large genetic differentiation is present in both nuclear and mitochondrial genomes. The two genera are also clearly diagnosed by wing patterns and shapes.
