Material examined. Holotype. Male, China, SW Yunnan, Xishuanbanna, Guanping env., 1000 m, 60 km N Jinghong, 28−30.iv.2003, leg. S. Murzin ( MWM, GenPr- Heterocera MWM – 28.018) . Paratypes: 2 males, same locality ( MWM) ; 1 female, China, W. Yunnan, Mou Ding county , 1300 m, 25°19′N / 100°32′E, 16.iii.−10.iv.2000, leg. Brechlin’s loc. coll ( MWM) ; 1 male, Yunnan, Manxi Ba Mts., Simao distr. , 18 km S Simao city, 16.iii.−10.iv.2000, ex coll. R. Brechlin ( MWM) .

Description. Male. Length of fore wing 13−13.5 mm. Antenna short, bipectinate, setae in medium third of antenna twice longer than antenna rod diameter, thorax and abdomen from above covered with long brown scales (except for medium third of abdomen, covered with light-grey scales), abdomen apically with long modified scales. Fore wing with blurred brown pattern, brown spots in discal cell; cubitally (from base to tornal angle) long, relatively wide crescent portion of grey androconium scales, between veins of radial trunk – two relatively wide short portions of grey androconium scales; marginal area and fringe mottled (with alternating brown and creamy spots). Hind wing light-grey with poorly expressed reticulated dark-grey pattern, anal angle creamy without pattern, marginal area and fringe mottled (with alternating brown and creamy spots).

Male genitalia ( Fig. 22 ). Uncus wide, with wide semicircular bifurcation apically, apical halves of uncus diverging at a right angle, wide, short, apices of uncus halves almost smooth; scaphium and subscaphium fused into long, relatively narrow spindle-like tube; gnathos arms short, lamellar; gnathos lamellar, with long thin lateral processes; valve short with equally rounded edges; saccular edge (in basal half) strongly sclerotized, tubulate, curved in distal third, with pyramidal harpe directed dorsally; juxta lamellar, robust; saccus almost reduced; phallus 2.5 times shorter than valve, thick, in distal third with robust spiky cornutus directed at a right angle to axis of phallus.

Female ( Fig. 13 ). Length of fore wing 17 mm. Antenna bipectinate, setae 1.5 times longer than antenna rod diameter. Thorax and abdomen (except for base of abdomen covered with brown scales) covered with creamy scales. Fore wing creamy with small brown spots along costal edge, brown strokes basally, underlining discal cell from below, brown stroke at top of discal cell, postdiscally – short oblique band from R 5 to CuA 1 consisting of three round brown spots, postdiscally and submarginally – dense sputtering of brown scales. Hind wing creamy with dense reticulated brown pattern of strokes. Fringe on all wings mottled, light at veins, brown between veins.

Female genitalia not studied.

Diagnosis. The new species clearly differs from all the species of the genus in the blurred brown pattern, in the curved end of the sclerotized saccular edge of the valve, and in the large females.

Distribution. China (Yunnan Province, south-western part).

Etymology. The new species is named after the collector of the type series – Sergej Murzin (Moscow).
