TYPE MATERIAL. Holotype: ♂, ( ZISP, gen.pr. Nr. 1919), PANAMA. Chiriqui province, near Volcan town, Totumas Mountain Cloud Forest , 8°53´N, 82°41´W, h – 1920 m, v–vi. 2018, A. Kozlov & Yu. Kovaleva.

DESCRIPTION. External characters.White hairs on forehead, the collar is dark brown. Thorax and tegulae are white. Labial palpi is thin, short, slightly tapered apically, equal to eye diameter in length, pale outside, brown inside. Antennas are pale yellow. Wingspan is 20 mm. Fore wing is pale yellow. Oblique brown stroke stretching from cleft base to costal edge. Small dark brown spot in first third of a fore wing. Apical part of a first lobe is framed in fine longitudinal brown strokes. Inside the cleft, fringe is yellowish-grey. Hind wings are grey, noticeably darker than fore wings, the fringe is monochrome grey. Leg are yellowish-grey. Spurs on legs of unequal length, outer spur is shorter than inner one, bases of spurs darkened with brown scales.

Male genitalia. Valves are asymmetric, narrow. Harpe on left valve is thin, long, noticeably protruding over valve apex. Saccular process on right valve is thin, bluntly rounded apically, extending almost to apex of a valve. Anellus arms are long, of unequal width, right one is slightly wider than left one. Saccus has an arc form. Uncus is narrow, arc formed. Aedeagus thin, almost straight, more than twice shorter than valve in length.

Female unknown.

DIAGNOSIS. In the male genitalia, by the harpe on the right valve, the anellus arms and the aedeagus, the new species is similar to Hellinsia shishkini Kovtunovich, Ustjuzhanin et Sinyaev, 2018 , but differs in the sacculus shape, in the pale yellow color of the fore wings with the oblique brown stroke and in the dark grey color of the hind wings, while in H. shishkini , all the wings are unicolorous silver-white without similar strokes.

ETYMOLOGY. The species as named after Jeffrey and Alma Dietrich for their invaluable assistance provided during the entomological research.
