Synonymy

Genus Chlosyne Butler, 1870

Cist. Entomol. 1(3): 38, no. 37. Type-species: Papilio janais Drury, 1782, Ill. Nat. Hist., 3: 22, index, pl. 17, figs. 5, 6, as replacement name. Proposed to replace Synchloe E. Doubleday, 1844, preoccupied (Code Articles 60.3, 67.8). The synonymy for this genus follows Wahlberg and Zimmerman (2000), Cladistics 16(4): 347-363.

      =    ‡Synchloe E. Doubleday, [1845]

List Spec. Lepid. Brit. Mus. 1: 76. Type-species: Papilio janais Drury, 1782, Ill. Nat. Hist. 3: 22, index, pl. 17, figs. 5, 6, by designation of Scudder (1875), Proc. Am. Acad. Arts Sci., Boston 10(2): 141, no. 253. Preoccupied by Synchloe Hübner, 1818, Zutr. Samml. exot. Schmett. 1: 26.

Chlosyne acastus (W. H. Edwards, 1874) (1870)

The name acastus has long been associated with this suite of taxa. The discovery that populations given the name sterope (W. H. Edwards, 1870), formerly considered a subspecies of Chlosyne palla (Boisduval, 1852), are actually conspecific with C. acastus, threatens the seniority of the latter name; see A. Warren (2005), Butts. Ore.: 225-232. Replacing acastus with sterope as the species-level name (e.g., Scott (2006), Papilio (n.s.) 12: 37-38), would create an unnecessary and cumbersome reassignment of names. A paper is being prepared to cite the evidence for implementation of Code Article 81.2.3, to grant acastus status as a nomen protectum.

Trans. Am. Entomol. Soc. 5(1): 16-17.

Original Combination: Melitaea Acastus

Type Locality: “Montana...Nevada...Southern Utah”; defined as “Provo Canyon, Utah County, Utah” by F. Brown (1966), Trans. Am. Entomol. Soc. 92(3): 402-403.

Types: Lectotype in CMNH, designated by F. Brown (1966), Trans. Am. Entomol. Soc. 92(3): 404, fig. 16 ♂ D&V; figured by W. Holland (1898), Butt. Book: pl. 16, fig. 11 ♂ D.

 

Chlosyne acastus sterope (W. H. Edwards, 1870)

Trans. Am. Entomol. Soc. 3(2): 189, 190-191, no. 3.

Original Combination: Melitaea Sterope

Type Locality: “Oregon”; defined as “Tygh Valley, Wasco county, Oregon” by Bauer (1975), in: Howe, Butts. N. Am.: 157.

Types: Lectotype in CMNH, designated by F. Brown (1966), Trans. Am. Entomol. Soc. 92(3): 407, fig. 17 ♀ D&V; figured by W. Holland (1931), Butt. Book (rev. ed.): 124, pl. 58, fig. 23 ♀ D.

Types: Holotype probably in OSU.

Gunder (1934), Can. Entomol. 66(6): 130, was the first to recognize that hewesi is a synonym of sterope.
