3.2. Nomenclature

Heppner (1995: 147) stated: "LACTURA Walker, 1854 ±Eustixis Hübner, [1827-31], Zuträge Samml. Exot. Schmett., 3:24. (Type-species: Eustixis pupula Hübner, [1827-31], ibid., 3:24 (fig. 489-490) (subsequently designated by Grote, 1874, Bull. Buffalo Soc. Nat. Sci., 2:152). Type locality: Georgia, USA). Kyrki (1990) noted this genus (not Eustixia Hübner, 1823, a genus in Pyralidae) as a senior synonym of Lactura. The names have been further confused due to two Hübner species having the same specific name: Eustixia pupula Hübner, 1823, in Pyralidae, and Eustixis pupula Hübner, [1827-31], in Lacturidae. Eustixis could have been a subsequent misspelling, but is here taken as an unused senior synonym, to be suppressed (Heppner, in prep, b) so both the genus name Lactura and the species name L. pupula can be maintained in use: this solution is supported by Nye and Fletcher (1991)." Heppner (1997) therefore made a formal request: "Case 3001. Lactura Walker, 1854 (Insecta, Lepidoptera): proposed conservation, and proposed conservation of the specific name of Eustixis pupula Hübner, |1831| (currently Lactura pupula)". This request was granted by the International Commission on Zoological Nomenclature (1999): "Opinion 1927. Lactura Walker, 1854 (Insecta, Lepidoptera): conserved, and the specific name of Eustixis pupula Hübner, [1831] (currently Lactura pupula): conserved."
