The genus Agnippe Chambers, 1872 in the Palaearctic Region is revised. Sixteen species are recognized as valid. Three new synonyms are established: A. conjugella Caradja, 1920 = A. haberlandii Amsel, 1961 syn. n., A. lunaki Rebel, 1941 = A. peni- cillata Amsel, 1961 syn. n., A. kuznetzovi Lvovsky & Piskunov, 1989 = A. zhengi Li, 1993 syn. n. Four new species are described: A. echinuloides sp. n. (S Ural, Tuva, Transbaikalia, Mongolia), A. turanica sp. n. (Uzbekistan, Kazakhstan), A. deserta sp. n. (Uzbeki- stan) and A. separatella sp. n. (S Iran). Description of all the species and an identification key are presented, accompanied by illus- trations of the adults, and male and female genitalia. INTRODUCTION Male and female genitalia were prepared using the unrolling technique as described by Pitkin (1986) and Huemer (1988). The genus Agnippe comprises about 30 species occur- Biological data were mainly extracted from bibliographic ring mainly in the Holarctic Region. There are also a few sources. For some species, personal observations and label data records for the Neotropical Region (Becker, 1984). were also available. Nearctic species are listed by Hodges (1983). Later Lee & The distribution of species was established primarily from the Brown (2008) synonymized Evippe Chambers, 1873 with material examined and supplemented by data in the literature. Agnippe Chambers, 1872, refined the definition of the The “Material” is arranged in geographical order from north- west to south-east and countries referred to by their current genus and proposed a list of Holarctic species based on names. new generic combinations. The Palaearctic Agnippe spe- cies have not been reviewed in full. Detailed descriptions RESULTS of two species that occur in Japan are given by Okado Check-list of Palaearctic Agnippe (1961), and the Chinese fauna was revised by Li (1993), Wang & Li (1994), Li & Zheng (1998) and Li (2002). A. lunaki (Rebel, 1941) =A. penicillata Amsel, 1961 syn. n. There are two European species included in the first A. syrictis (Meyrick, 1936) volume of Gelechiidae of Europe (Huemer & Karsholt, A. novisyrictis (Li, 1993) 1999). A. yongdengensis (Li, 1993) In the course of our study, sixteen Agnippe species A. echinulata (Li, 1993) were recognized in the Palaearctic Region, four of which A. dichotoma (Li, 1993) are described as new; three new synonyms are A. echinuloides sp. n. established. All the species are described or redescribed, A. turanica sp. n. along with illustrations of the adults and the male and A. albidorsella (Snellen, 1884) female genitalia of each taxon.
