Hemming (1967) stated:-
This is another of the cases in which a generic name was published by Hübner in two works which were published within a very short time of one another, in which he placed different species in the genus so named. The works concerned were volume 1 of the Zuträge and the Verzeichniss respectively. Scudder, while realizing that much of the text of the butterfly portion of the Verzeichniss was published after 1816, the date given on the title-page, decided nevertheless it would be best in the state of information then available to treat all the names in question as having been published in that year - this decision being taken, as he said, for "convenience and uniformity" (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 98) ; he therefore accorded priority to names published in the Verzeichniss over names published in the Zuträge. For Strymon as of the Verzeichniss he selected Hesperia titus Fabricius, 1793, (Ent. Syst. 3 : 293) as type-species as early as 1872 (4th Ann. Rep. Peabody Acad. Sci. 1871 : 53). That species was not cited in the Zuträge as belonging to the genus Strymon, and as the first volume of the Zuträge was published in 1818, it has priority over the name Strymon as published in the Verzeichniss which was published, as is now known, in 1819. Thus, Scudder's type-selection based on the Verzeichniss is invalid. It was not until 1922 that one of the Zuträge species was selected as the type-species of Strymon, Riley in that year selecting Strymon melinus Hübner as type-species.
The case of the name Strymon Hübner was brought to the attention of the Commission in 1934 jointly with the name Bithys Hübner, 1818. No action was then taken by the Commission, the application being withdrawn temporarily in order to permit of a further examination of the issues involved. The Commission's decision was later embodied in Opinion 165 (1945, Opin. int. Comm. zool. Nom. 2 : 359-374). This case was resubmitted to the Commission in a revised form in 1954, in which, so far as the name Strymon Hübner was concerned the Commission was asked to place the name Strymon Hübner on the Official List with Strymon melinus Hübner as type-species. This proposal was approved by the Commission in Opinion 541 (published in 1959, loc. cit. 20 : 87-102), the name Strymon Hübner being placed on the Official List as Name No. 1332.
STRYMON was included within the subfamily LYCAENIDAE: LYCAENINAE by Ackery et al., in Kristensen (1999).
Robbins (2001. J. Lepid. Soc. 55(3): 85-100 included Callipareus Scudder, 1872; Callicista Grote, 1873; Uranotes Scudder, 1876; Eiseliana Toledo, 1978; and Heoda Johnson, Miller & Herrara, 1992 as junior synonyms of Strymon, Hübner, 1818.
