TYPE MATERIAL. Holotype – ♂ (gen. pr. No. 220302, IZBE), South Africa:

Western Cape prov., Kleinmond Nature Reserve , 34°19' N, 18°59' E, 22.XI 2016 ,

leg. K. Nupponen, R . Haverinen, A. Pototski ( IZBE). Paratypes : same data as holotype, 3 ♀ (1 ♀, gen. pr. No. 220303, IZBE) + 2 ex. (without abdomens) ( IZBE,

ZISP, CUK); Western Cape prov., Outeniqua Mts., 32 km SSW of Oudtshoorn,

33°52' N, 22°02' E, h= 832 m, 02.XII 2016, 1 ♀, leg. K. Nupponen, R. Haverinen ,

A. Pototski ( CUK).

DESCRIPTION. Male and female. Head with light-brown hairs, thorax and tegulae yellowish brown. Labial palpi thin, straight, dark brown, in length equal to longitudinal eye diameter. Antennae striated, with alternating dark brown and white segments. Wingspan 13–16 mm, (holotype – 16 mm). Fore wings yellowish brown.

Before cleft – relatively wide dark-brown spot, gradually narrowing as ray and ending with small dark dot in medium part of wing. Longitudinal portions of brown scales along costal margin of first lobe. Inner margin of first lobe and its apical part yellow. Second lobe apically dark brown, with acute tip. Fringe inside cleft dark brown. Hind wings slightly darker than fore wings, unicolorous, brown-grey. Hind legs yellow.

of holotype (gen. pr. No. 220301, IZBE); 6 – female genitalia (gen. pr. No. 220303, IZBE) .

Male genitalia. Valves asymmetric. Saccular process on left valve extend beyond its middle, basally wide, apically narrowing and acute. Saccular process on right valve stick-like, short, located in medium part of valve. Sacculus narrow, hardly reaching middle of valve length. Uncus narrow, short, apically acute. Saccus convex.

Anellus arms narrow, approximately equal in length and width. Aedeagus thin, almost straight, 1.5 times shorter than valve, without cornuti.

Female genitalia. Papillae anales short, triangular. Posterior apophyses straight,

apically slightly extended, bent. Anterior apophyses thin, significantly more narrow than posterior. Antrum relatively short, tubulate. Ductus short, immediately passing into elongated oval bursa copulatrix. Ductus seminalis relatively wide, slightly shorter than bursa copulatrix. No signa.

DIAGNOSIS. In the male genitalia, in the shape of the saccular process on the right valve and the saccus, the new species is similar to Hellinsia bidzilya Ustjuzhanin et Kovtunovich, 2019, but clearly differs in the saccular process on the left valve and the wider valves. Additionally, the aedeagus of the new species is thinner and

1.5 times shorter than valve, while in H. bidzilya the aedeagus is significantly thicker and equal to the valve in length.

DISTRIBUTION. South Africa: Western Cape.

HABITAT. The new species was found in the mountain meadows in November

– December ( Fig. 7 ).

ETYMOLOGY. The new species is named after Risto Haverinen, the Finnish entomologist-lepidopterologist, a participant of the expedition to the South Africa.
