Material. Holotype (male), India, Sikhim [Sikkim], 2200−3000 m, 7.vii.2003, leg. I.A. Sergeev (slide Prozorov 2023-0576; ZISP).

Description. Male ( Fig. 1 ). Length of fore wing 11 mm. Antennae short, light-orange; proximal half bipectinate, distal half simple (filiform). Head, thorax and abdomen densely covered with black scales. Fore wing narrow, apically sharp, semi-transparent, with sputtering of rare black and ocher scales, narrow mottled field along costal margin (with alternating black and ocher portions), wide mottled area along anal margin, slight sputtering of ocher scales at veins; fringe mottled (dark at veins and ocher between veins). Hind wings short, apex slightly pulled out, semi-transparent, with sputtering of rare black and ocher scales, narrow creamy portion along costal margin, extended black opaque portion at anal margin. Fringe creamy, at black opaque portion – black.

Male genitalia ( Fig. 6 ). Uncus tapered, slightly narrowing from base to apex, apically semicircular; tegumen trapezoidal; gnathos arms thin, long, not fused; gnathos reduced; valve leaf-like with almost even edges, without harpes; juxta semicircular, saddle-like with pair of leaf-like lateral processes of medium length; saccus semicircular, of medium size; phallus slightly shorter than valve, thick, poorly curved in medium third, vesica with large finger-like cornutus (cornutus twice shorter than valve).

Female unknown.

Diagnosis. Externally, clearly differs from R. nigra , which has only a small semi-transparent portion in the middle of the fore wing, this portion is framed in a wide black border, there are also significant differences in the male genital structure – in R. nigra the valve is apically acute, the phallus is very big, slightly longer than valve. Externally, the new species is most close to the recently described species, R. radzha (distributed in Southern India), from which it differs in the following characters: the mottled portion on the anal margin of the fore wing in R. radzha does not reach the anal angle of the wing, the gnathos arms are significantly shorter, the valve is noticeably narrowing basally.

Etymology. The new species named after the well-known original Russian painter Lucy Voronova (Lyudmila Vladimirovna Voronova, 15.12.1953). The name is dedicated to the release of the anniversary catalog which is timed to the 70 th anniversary of the painter.

Distribution. NE India, Sikkim.

Flight period. July.
