Anania coronata (Hufnagel), a Holarctic species of pyraustine crambid moth, has long been treated as having two geographically separated subspecies – the nominotypical Anania coronata in the Palaearctic Region and Anania coronata tertialis (Guenee)´ in the Nearctic Region. Maximum likelihood and Bayesian inference analysis of mitochondrial DNA barcodes both recover four well-supported, reciprocally monophyletic groups within Anania coronata. Qualitative and quantitative analyses of genital structures reveal diagnostic differences that correspond to the four barcode lineages. On the basis of both molecular and morphological evidence, we conclude that Anania coronata is actually a complex of four species. Anania coronata (Hufnagel) is restricted to Europe, whereas three species occur in North America: Anania tertialis (Guenee),´ Anania plectilis (Grote & Robinson) and Anania tennesseensis sp.n. Yang. Introduction taxa have long been regarded as synonyms of Anania coronata tertialis: Botys plectilis Grote & Robinson and Anania coronata (Hufnagel) is a Holarctic species that ranges Botys syringicola Packard (Dyar, 1903; McDunnough, 1938; from Europe through Asia to Japan, and to North America Munroe, 1976; Munroe et al., 1995; Hodges et al., 1983). (Munroe, 1976; Inoue, 1982; Speidel, 1996; Sinev, 2008). Munroe (1976) indicated that more than one species might Munroe (1954, 1976) and Munroe et al.

He retained Botys syringicola as a synonym of Anania tertialis. Despite the great value of genital characters for species Material and methods recognition, the preparation of genitalia is so time consuming that it limits the use of this approach for large-scale specimen Taxon sampling sorting and examination. As a consequence, cryptic species are commonly overlooked, particularly in taxa with broad Eighty-nine specimens of Anania coronata from Europe distributions (Smith et al., 2006; Burns et al., 2007; Kristensen and North America (Fig. 1) were analysed as well as 20 et al., 2007).
