Name
Biston quercii (Oberthür, 1910) – Wikispecies link – Pensoft Profile
- Amphidasis quercii Oberthür, 1910[1], Études Lépid. comp., 4: 676, pl. 51, fig. 433. Holotype ♀, China: Sichuan, Tien-Tsuen. (ZFMK)
- Biston quercii : Prout, 1915[2], in Seitz, Macrolepid. World, 4: 359.
- Biston (Eubyjodonta)quercii : Wehrli, 1941[3], in Seitz, Gross-Schmett. Erde, 4 (Suppl.): 434, pl. 36: f.
Diagnosis
The wing pattern of this species is similar to that of Biston falcata as follows: the forewing antemedial line is black, slightly waved; the postmedial lines of both wings are black and dentate; broad brown bands are present basally of the forewing antemedial line and distally of the postmedial lines of both wings; the speckles scattered on the wings are black, and often gather to a black patch basally of the submarginal lines; the hindwing medial line is black and double. But it can be distinguished by the following characters: the outer margins are more undulating, there are distinct marginal processes in the centre of both wings, absent in Biston falcata; the hindwing discal spot is present. The male genitalia are similar to those of Biston falcata as follows: the apex of the uncus is round; the median process of the gnathos is broad and round apically; the juxta is long, narrow, acute and with a longitudinal arris apico-ventrally; the cornutus is shaped as a spinous patch. But this species is characterized by the narrower juxta and the longer spines of the cornutus.
