TYPE MATERIAL. Holotype: ♂, ( ZISP, gen.pr. Nr. 1918),

PANAMA. Chiriqui province, near Volcan town, Totumas Mountain Cloud Forest , 8°53´N, 82°41´W, h – 1920 m, v–vi.2018. Paratypes: 2 ♂♂, 28.iv–02.v.2019; 2 ♂♂, 1 ♀, 24–27.v.2019, same data as holotype, A. Kozlov & Yu. Kovaleva ( ZISP, CUK) .

DESCRIPTION. External characters. Forehead is covered in pale yellow hair, collar is colored brown, thorax and tegulae are white. Labial palpi is thin, short, slightly tapered apically, equal to longitudinal eye diameter. Antennas are pale yellow. Wingspan length is 21 mm. Fore wing is colored pale yellow. Stretching from cleft base to costal edge, there is an oblique brown stroke. On two first lobes of fore wing apical parts there are fine but clear brown horizontal strokes: one on the first lobe, three on the second. On a fringe of an outer edge, fore wing in the middle is covered in brown scales. On the inside cleft the fringe is pale yellow, along an outer edge is slightly darkened with pale brown hairs. Hind wings are grey, noticeably darker than fore wings, with monochrome grey fringe. Legs are pale yellow, almost white. Male genitalia. Valves are asymmetric, narrow. At the base of a left valve there is an harpe, bent at right angle. Saccular process in distal part of right valve is thin and sharpened as a slightly concave needle. Anellus arms are of unequal length, right one is slightly longer and wider. Saccus has an arc form. Uncus is narrow. Aedeagus is thin, slightly concave, twice shorter than valve in length.

Female genitalia. Antrum is cylindrical, passing into short ductus bursae. Bursa copulatrix is oval with a small signum. Ductus seminalis is narrow and long. Posterior apophyses are thin, twice longer than papillae anales. No anterior apophyses.

DIAGNOSIS. In the male genitalia, by the shape of the harpe on the left valve and by the anellus arms, the new species is similar to Hellinsia angulofuscus (Gielis, 1991) , but differs by the thin sharp saccular process in the distal part of the right valve.

ETYMOLOGY. The species is named after Tatiana Dmitrievna Demchenko, the grandmother of the third author.
