Clepsis unifasciana (Duponchel) 3 
Tortrix unifasciana Duponchel, 1843, Hist. Natur. Lepid. France, Suppl. 
4: 135; Klots, 1941, Bull. Brooklyn Entomol. Soc., 36: 12 6. 
Clepsis unifasciana: Obraztsov, 1955, Tijdschr. v. Entomol., 98: 215 
(synonymy) . 
Diagnosis. — Clepsis unifasciana most closely resembles C. peritana 
(Clemens) and C. vires cana (Clemens) among Nearctic species but 
has a rusty or reddish brown tint. From C. peritana it differs also in 
having a well developed costal fold in the male and a less distinctly 
marked forewing; from C. vires cana,, in having a longer costal fold, 
no strongly contrasting outer costal spot, and a dark gray (rather 
than pale) hindwing (figs. 3 and 4). With their forewing patterns 
usually obscure, females of all three species look more similar than 
the males; but the lack of any differentiation of the outer costal 
spot and the rust-orange coloration of the forewing distinguish C. 
unifasciana females. 
The male genitalia of C. unifasciana are at once set apart by the 
elongate, curving, flattened setae of the medial face of the valva 
(see Obraztsov 1954; Pierce and Metcalfe 1922). The female 
genitalia have an elongate sclerotized band in the ductus bursae, 
somewhat as in Archips argyrospilus (Walker), and are unlike 
C. peritana and C. virescana. 
Geographic distribution. — Clepsis unifasciana is widespread in 
the Palearctic, having been recorded from the British Isles, main- 
land Europe, northwest Africa, Turkey, Syria, and the Amur and 
southern Ussuri region of the eastern Soviet Union (Meyrick 1895; 
Kennel 1910; Obraztsov 1955). 
In the Nearctic we know of only four localities. Klots’ (1941) 
record was based on specimens taken at Valley Stream, New York, 
in western Long Island in 1939. Our latest record comes from this 
same general area. Klots was next to collect the species, 1 1 years 
later, immediately north of New York City on the mainland. After 
another 13 years, C. unifasciana was found in central Connecticut 
(fig. 6). 
Biology. — In Europe this species feeds on privet, Ligustrum 
vulgare (Meyrick 1895; Kennel 1910) ; and at Valley Stream, New 
York, A. G. Richards, Jr., found adults of C. unifasciana excessively 
3 Bradley and Martin (1956) exhumed the name consimilana Hiibner, 
1822, for this species and relegated unifasciana to synonymy. The Hiibner 
name had been treated as of doubtful status by Obraztsov (1955) and 
others, presumably because there is no type; Bradley and Martin gave no 
explanation for their reversal.
