Diagnosis. Libythea lepita is sister species to L. celtis and shares with it a gradually incrassate antenna, but the former can be distinguished from the latter by having: 1) a hindwing anterior margin that is weakly lobed near the fusion of the costa and Sc + R 1, and 2) the proximal margin of the forewing dorsal orange mark between M 3 and CuA 2 projects proximally along CuA 1, forming a curved or angled margin, which is straight in L. celtis .
Distribution. Northern India and Pakistan, east to China, Korea, and Japan.
Biology. Host plant species include: Celtis boninensis Koidz, C. formosana Hayata , C. jessoensis Koidz , and C. sinensis Pers. (Celtidaceae) . Trema orientalis (L.) Blume ( Cannabaceae ) has been reported but this record is questionable. Host plant data were extracted from: Kono & Sawamoto (1939), Shirôzu & Hara (1960), Fujioka (1975), Kawazoé & Wakabayashi (1976), Shin Gakkai (1979), and Fukuda et al. (1983).
Remarks. Evans (1910) synonymized lepita with celtis , but without any specification of the number of specimens studied, the types examined, or the species concept used. Many faunal and life-history studies have followed Evans (1910) and treated lepita as a synonym of celtis (e.g., Nagano 1933, Gaede 1932, Shirôzu & Hara 1960, 1962, Fujioka 1975, Kawazoé & Wakabayashi 1976, Fujioka & Ôya 1977, Lee 1982, Fukuda et al. 1983, Inomata 1990, Io 1994, Park & Kim 1997, Aoyama 1998, Io 1998, Osada et al. 1999, Igarashi & Fukuda 2000).
However, Hans Fruhstorfer, an authority on butterflies, treated lepita as a separate species. He wrote, ‘I formerly believed to be right in considering lepita as a geographical form of celtis , but although it is certain that lepita appears everywhere where celtis disappears, I think to be allowed to treat lepita nevertheless as a species’ (1914: 769). Some authors (e.g., Matsumura 1919, Kasahara 1936, Kono & Sawamoto 1939) chose to follow Fruhstorfer (1914) and regarded the Japanese population as L. lepita . Yoshimoto (1999) discussed the possibility that celtis and lepita may be separate species, but did not make any taxonomic changes.
Based on the morphology and distributions of more than 800 specimens examined from Asia and Europe, I follow Fruhstorfer (1914), and treat celtis and lepita as separate species. Two autapomorphies distinguish L. lepita from L. celtis : the hindwing anterior margin is weakly lobed near the fusion of the costa and Sc + R 1, and the proximal margin of the forewing dorsal orange mark between M 3 and CuA 2 projects proximally along CuA 1, forming a curved or angled margin. Furthermore, an orange mark in the dorsal surface of forewing cell CuA 2 and hindwing cell Rs is almost always present in L. celtis but nearly always absent in L. lepita . A lepita adult collected from a natural population can also typically be distinguished by its larger wing size (usually 1–2 mm larger than L. celtis ). The original description is attributed to Moore (1858). While Moore’s A catalogue of the Lepidopterous insects in the museum of the Hon. East-India Company has a publication date of 1857 on the front page, the actual publication date was 1858, according to Cowan (1975).
