Description. External characters. Thorax and tegulae light-brown. Collar on head with brown sticking out hairs. Labial palpi thin, yellowish-brown, straight, equal to longitudinal eye diameter in length. Antennae yellow, interspersed with tiny brown scales. Wingspan 21-24 mm, in holotype – 24 mm. Fore wings light-brown. Small, round, poorly expressed spot at cleft base. Costal edge of fore wing darkened. Distinct dark-brown almost black elongated stroke on first lobe above cleft along costal edge, followed by white stroke and further to apical part of lobe there are tiny black strokes. Bright dark brown spots and dots along outer edge of fore wing. Hind wings unicolorous, slightly lighter than fore wings. Small dark-brown dots on hind wings along outer edge of three lobes. Fringe on all wings yellowish-brown. Hind legs light-yellow.

Male genitalia: Uncus narrow, slightly curved, apically acute. Valves asymmetric, left valve slightly wider than right valve. S accular process on left valve smoothly bent into ring. Saccular process on right valve narrow, rod-like, apically acute and slightly bent, basally wide. Anellus arms basally wide, gradually narrowing to apices, left arm slightly shorter than right arm. Saccus arched. Aedeagus smoothly arched, twice shorter than right valve.

Female genitalia: Papillae anales narrow, elongated. Posterior apophyses thin, long. Antrum goblet-like. Ductus short, wide, smoothly passing into relatively short oval bursa copulatrix. Ductus seminalis long, more than three times longer than bursa copulatrix. No signa.

Differential diagnosis. In the male genitalia, in the shape of the s accular process on the left valve, the new species is similar to Hellinsia savrasovi Kovtunovich & Ustjuzhanin, 1918 , but differs in the shape of the s accular process on the right valve and in the wings colour.

Distribution: Ecuador (Morono Santiago, Napo and Pichincha Provinces).

Flight period: January, March, October, December.

Etymology: The species is named after Dr. Cees Gielis, a Dutch prominent specialist on Pterophoridae of the world fauna, who made a great contribution to the study of plume moths of the Neotropical region including Ecuador.
