Material. Holotype (male): Namibia, Region Iikaras , Klein Ausvista, Umg. Aus Region, 1471 m, S 26º40′19′′ / E 16º14′53′′, 01.ii.2016, leg. H. Sulak, S. Naumann & Elk Ott (Museum Witt, Genital Präparat Heterocera No. 32.731) . Paratype (1 male), same locality (Museum Witt, Genital Präparat Heterocera No. 37.160) .

Description. Antenna bipectinate, crest processes long, 3−3.5 times longer than antenna rod diameter. Male fore wing 10−13 mm in length (holotype – 10 mm). Fore wing brown, with sputtering of silver-grey scales at root and discally, series of big blurred dark-brown spots postdiscally (partially fused into wide transverse band), thin dark-brown transverse line submarginally, very thin light stripe on border of wing, fringe brown, unicolorous. Hind wing brown, without pattern, very thin light stripe on border of wing, fringe brown, unicolorous.

Male genitalia. Uncus long, thin, gnathos arms relatively robust, short; gnathos compact, covered with fine spikes; valve narrow, long, outer edge semicircular, costal and abdominal edge almost smooth; transtilla processes short, laminated, apically strongly curved and tapered, apical end strongly serrated (dorsally and abdominally); juxta tiny, with wide leaf-like lateral processes, saccus almost reduced; phallus short, robust, strongly curved in medium third, with needle-like cornutus in vesica.

Female unknown.

Diagnosis. The new species is characterized by the bright dark coloring, and the transtilla processes apically strongly serrated (dorsally and abdominally).

Etymology. The new species is named after the well-known German entomologist Stephan Naumann – specialist in Saturniidae , one of the collectors of both new species.
