Type material: Holotype, male, ( ZISP, gen.pr. Nr. 1985), PARAGUAY, Dep. Pte. Hayes Laguna Capitan, S 22°32’ W 59°40’, 27–29. V. 2017, U. Drechsel. GoogleMaps

DESCRIPTION. External characters. Head yellow, with ocher collar, thorax and tegulae with yellowish scales. Labial palpi light-brown, thin, straight, slightly shorter than longitudinal eye diameter. Antennae greyish-brown, scape noticeably thickened. Wingspan 15 mm. Fore wings pale-yellow. Small oblique brown spot at cleft base. Fringe inside cleft yellow, only distally brown on both lobes. Narrow brown spot on second lobe apically from outside. Hind wings of the same color as fore wings. Hind legs pale-yellow.

Male genitalia. Valves narrow, elongated, asymmetric. As base of left valve – small straight harpe slightly narrowing apically. Saccular process on right valve narrow, located at its base, slightly extended distally. Anellus arms of different length, right one longer and wider than left one. Saccus arched. Uncus thin, arched, apically acute. Aedeagus smoothly curved in medium part, 2.5 times shorter than valve in length, with needle-like cornutus distally.

Diagnosis. In the male genitalia, in the elongated narrow valves and the saccular process on the left valve, the new species is close to Hellinsia villagrani Gielis, 2013 , but differs in the structure of the saccular process on the right valve, in the unequal anellus arms and in the special color of wings in the adults.

Flight period. May.

Distribution. Paraguay.

Etymology. The species is named after the Paraguay entomologist Mr. Ulf Drechsel (Asunción), who has been providing us during several years with Pterophoridae specimens for examination.
