DESCRIPTION. External characters. Head, thorax and tegulae with light-brown hairs. Labial palpi grey, straight, apically acute, twice longer than longitudinal eye diameter. Antennae thin, brown. Wingspan 24–29 mm, in holotype 24 mm. Fore wings greyish-brown. Distinct bright wide spot on first lobe above cleft base, oblique light band closer to end of first lobe, also extending to second lobe. Poorly expressed brown spot on fore wings medially. Fringe on outer edge of both lobes brown at base, light-grey at ends. Fringe on outer edge of fore wings with alternating portions of brown and light portions of hairs. Hind wings of the same color as fore wings, fringe on third lobe light with distinct bundle of brown hairs in medium part. Hind legs yellow with brown portions of scales at bases of spurs.

Male genitalia. Valves narrow, symmetric, apices slightly narrowing. Sacculus basally wide, smoothly narrowing distally.Uncus narrow, long, apically acute.Tegumen bilobed. Anellus arms basally wide, then passing to narrow long barlike processes. Saccus round. Aedeagus curved at a right angle, basal process directed forwards, perpendicular to aedeagus.

Female genitalia. Papillae anales wide, oval. Posterior apophyses narrow, long. Anterior apophyses 4–5 times short- er than anterior ones. Antrum tubulate, relatively wide, smoothly passing into narrow sclerotized ductus. Bursa copulatrix oval with two thin slightly curved needle-like signa.

DIAGNOSIS. Externally and in the male genitalia, the new species is close to Platyptilia wojtusiaki Gielis, 2014 , but differs in the presence of the wide light spot above the cleft of the first lobe and in the lighter color of the wings. In the male genitalia, it differs in the narrow valves, narrow uncus, and the shape of the saccus. Additionally, the new species differs in the basal process of the aedeagus, directed forwards, perpendicular to the aedeagus, while in P. wojtusiaki it is clinging to the aedeagus.

Flight period: September–December, April, May.

DISTRIBUTION. Colombia.

ETYMOLOGY. The species is named after Alexey Yakovlev, doctor, naturalist and traveler, participant of Russian entomological expeditions, candidate of medical sciences (Moscow, Russia).
