Hemming (1967) stated:-

In the early nineteen-thirties there were differences of opinion among specialists on the question whether Papilio lubentina Cramer, the type-species of the present genus should on taxonomic grounds be treated as being congeneric with Symphaedra alcandra Hübner, [1819], the type-species of the genus Symphaedra Hübner. For those who took the view that these species were congeneric with one another, the names Euthalia and Symphaedra were subjective ;- 9 synonyms of one anther. As these names were published on the same date and in the same work (Euthalia on page 41 ; Symphaedra on page 40), the question arose as to which of these names should be given precedence over the other. This was a question on which at that time there was no clear provision in the Code, some authors adopting the First Reviser Principle (a course which in retrospect is now seen to have been correct), while others, including the majority of lepidopterists, guided themselves by the so-called Page Precedence Principle. Thus, from the standpoint of this last group of specialists the name Euthalia Hübner would be a junior subjective synonym of Symphaedra Hübner for any worker who might identify with one another the genera bearing these names. From the point of view of stability in nomenclature, the rejection of the name Euthalia in favour of the name Symphaedra would have been open to very strong objection : the genus Euthalia is a large and highly characteristic genus of Indo-Oriental Nymphalids, while Symphaedra, as hitherto interpreted, consists of a single species occurring in Ceylon, Southern India and Sikkim.

To obviate the risks described above, it was decided to ask the Commission to give a ruling which would protect the name Euthalia Hübner from the danger of attack by the name Symphaedra Hübner on grounds of priority. An application in this sense was submitted to the Commission jointly by myself and Mr. N. D. Riley in October 1934. It was approved by that body at its meeting held at Lisbon in September 1934 but various causes combined to delay the promulgation of Opinion 167, containing that decision, until 1945 (Opin. int. Comm. zool. Nom. 2 : 399-410). By the ruling given in that Opinion it was directed that the Law of Priority should not be invoked to secure precedence for the name Symphaedra Hübner over the name Euthalia Hübner, and the name Euthalia Hübner, so endorsed, was placed on the Official List of Generic Names in Zoology as Name No. 613.

EUTHALIA was included within the subfamily NYMPHALIDAE: LIMENITINAE by Ackery et al., in Kristensen (1999).

The higher classification used here follows Lamas (2008).
