P. cxxxiv ( MNHN); 2 ♂♂, CHINA: Sichuan, Ebian, Heizhugou, 1800–2000 m, 16–18.VII.2014, leg. S-y. Lang (LSY); 1 ♀, ditto, 18.VIII.2013, S-y. Lang (LSY); 1 ♀, Hanyuan, Qingxi, Mt.

Diagnosis. ♂ Forewing length: 27.5–28 mm. L. manzorum can be distinguished from the other species of the manzorum- group by the combination of the following characters: a) underside of both wings with reddish fasciae and bars that are thicker and wider than those in other species(e.g. width of forewing postdiscal fasciae in space 3: 1.2–1.5 mm in manzorum , 1.0– 1.1 mm in others; width of hindwing postdiscal fasciae in space 3: 1.5–1.6 mm in manzorum , 0.9–1.2 mm in others); b) underside of hindwing with a reddish spot often present near the lower edge of the discoidal cell, which is absent in the other species; c) gnathos evenly broad, whereas it is expanded and pointed distally in L. monilifera ( Fig. 25 a) and gradually tapered distally in the other species ( Figs. 25 c, d); d) the apical part of the valva is pointed without distinct dorsal lobe, whereas it has a well-developed dorsal lobe in L. monilifera ( Figs. 22, 23 ); e) ventral edge of valva only slightly protruding ( Figs. 19, 20 ), whereas the central part of the ventral edge is angular in the other species.

Note. The male illustrated in figs. 5 and 6 is an aberrant individual in which the hindwing postdiscal blackish spots in cells M2 and M3 are fused to a single spot on both sides.

Distribution. China (Sichuan).
