Oberthueria formosibia Matsumura, 1927, Journal of the Faculty of Agriculture, Hokkaido Imperial University (J. Coll. Agric. Hokkaido Univ.), 19: 50, pl. 5, fig. 45. TL: “ Formosa (Horisha)=(Taiwan (Nantou))”. Holotype designation by monotypy: male (HUM) [examined]. The published description referred to only one specimen (the holotype), but two specimens with “ type ” labels were found in HUM.
Oberthueria falcigera Butler, 1878: Chu & Wang, 1993, Sinozoologia 10: 237; Chu & Wang, 1996, Fauna Sinica Insecta 5: 48. Misidentification.
Diagnosis. Characterized by its strongly serrate wing margins, contrasting pattern, non-bifurcate hindwing tail and slender harpe.
Specimens examined. [TAIWAN] 1 male, Holotype deposited in HUM with the label “male, holotype of Oberthueria formosibia Matsumura, 1927, Baibara, 22.VII.1925, Kikuchi leg.”; 40 males, from different localities of Taiwan (Ilan, Taitung, Nantou, Taoyuan, Hualien, Miaoli) (MWM); Yilan County: 2 females, Fushan Botanic Garden, 18.VIII. 2010, 500 m, Guo-Hua Huang leg. (HUNAU); 1 male and 1 female, Mingchi, 1050 m, 23.V.2012, Shipher Wu leg. (TFRI); Nantou County: 1 male and 1 female, Renlun, 1400 m, 22.IV.2010, Shipher Wu leg. (TFRI); Hualien County: 2 males, Ci’en, 1950 m, 25.V.2012, Shipher Wu & Wei-Chun Chang leg. (TFRI); 1 male, Guanyuan, 2400 m, 13.IX.2012, Shipher Wu leg. (TFRI).
Bionomics. The species is apparently montane, being known from altitudes of 500–2900 m, and with two generations per year. Moths are on the wing from late March to early July and again from August to early October (Plate 7E–7G). The larvae feed on Acer species (Plate 7H, 8A–8B), a unique host plant association in Bombycidae. It is illustrated, with a cocoon and a live female, at http://caterpillartaiwan.blogspot.co.uk/search/label/ Endromidae. The larvae have a peculiar cobra-like thoracic “hood” and a long anal horn. Chu and Wang (1996) also reported that the larvae fed on Quercus spp.
Distribution. Taiwan.
Remarks. The species is restricted to Taiwan. It was incorrectly recorded from the continent by Zolotuhin (1995).

Euphranor caeca Oberthür, 1880, Etudes d’Entomologie 5: 40, pl. 6, fig. 2. TL: [Far East of Russia], [south of Vladivostok], “Ascold”. Syntypes: 2 males (BMNH) [examined].
Oberthueria falcigera Butler, 1878; Chu & Wang, L.Y. (1996: 48). Misidentification.
Diagnosis. This species is darker ground color without a pinkish tint and, especially, the angled but not bifurcate hindwing tails most clearly distinguish it from its congeners.
