Beck leg.; 1 ex. without abdomen (CUK), S-E Ethiopia, Bale, Bale Mts., 13km SW Goba, 3300 m, Hangaso, V.2008, R. Beck, leg.; 1 male (ZSM), S. Ethiopia, Kafa Region, SNNPR, Bonga, 1767 m, N 7°16'0.39'', E 036°11'424'', 01–13.XII.2014, D. Wiersbowsky leg.   
 External characters. Head, thorax and tegulae brown. Labial palpi brown, twice longer than longitudinal eye diameter, apically acute. Forehead with conical bundle of scales, equal to eye diameter. Antennae thin, dark-brown. Wingspan 28–30 mm, in holotype 28 mm. Fore wings brown-yellow. Base and rear portion of wing yellow, front portion brown, darker than rear portion. Dark-brown narrow transverse stroke at cleft base. Outer edge of both lobes brown. Small spots of scales along rear margin of fore wing medially and distally. On hind wing, fringe of third lobe with dark-brown hairs from base to middle. Fringe basally more extended with saturated color, then, to medium part, more narrow and fading.   
 Male genitalia. Valves symmetric. Cucullus detached and slightly narrowing. Sacculus basally extended, medially narrowing, apically acute. Tegumen bilobed. Uncus narrow, slightly curved, apically slightly tapered. Juxta narrow, arched. Anellus arms short, wide. Saccus with narrow oval outer edge from below and with two sclerotized spikes slightly tapered apically, on inner edge. Aedeagus curved almost at right angle, basal process wide, directed to aedeagus, equal to coecum in length. Cornuti absent.   
 Female genitalia. Papillae anales short, oval. Posterior apophyses thin, long, more than three times longer than papillae anales. Anterior apophyses shorter than posterior, slightly concave. Antrum tubulate. Ductus bursae long, sclerotized, membranous only at confluence to bursa. Bursa copulatrix large, pearshaped. Signa narrow, slightly curved, apically tapered.   
 Diagnosis. In the wings color and in the fringe on the third lobe of the hind wing, the species belongs to the species group: Platyptilia aarviki Gielis, 2008, Platyptilia mughessi Kovtunovich & Ustjuzhanin, 2014, Platyptilia sabia (Felder & Rogenhofer, 1875), Platyptilia stanleyi Ustjuzhanin & Kovtunovich, 2016. In the male genitalia, in the shape of the saccus with two spikes, the new species is close to P. aarviki, from which it differs in the wide arms of the anellus not fused apically like in P. aarviki.   
 Flight period. May, October–December.   
 Distribution. Ethiopia.   
 Etymology. The species is named after a reliable friend and a professional collector, Robert Beck (Munich, Germany), who managed to get the type series of the new species in Ethiopia.
