Description. Male ( Figs 1–3, 6 ). Forewing. Forewing length: 18–22 mm. Slightly c-shaped. Hindwing. May have medioanal brown field. Genitalia ( Figs 20–23 ). Cucullus with blunt apex, caudal half covered with minute dents. Female ( Figs 4–5 ). Forewing. Forewing length: 27–28 mm. Wing pattern and genitalia ( Fig. 31–32 ) with generic characters, see above.

Variability. Males may be paler ( Fig. 2 ) or darker ( Fig. 3 ). Medial and lateral spurs of the eighth sternite in male genitalia vary in size ( Figs 20–23 ). Females may be paler ( Fig. 5 ) or darker ( Fig. 4 ).

Diagnosis. Adult males of R. yahya sp. n. have apically narrower forewing without medial dark strokes in the external line, the hindwing lacks an external dark brown field and the overall coloration is paler ( Figs 1–3, 6 ), the cucullus and lateral spurs of the eighth sternite are relatively short ( Figs 20–23 ), whilst adult males of R. edita sp. n. have wider forewings with medial dark strokes in external line, the hindwing has an external dark brown field and the overall coloration is darker ( Figs 7–11 ), the cucullus and lateral spurs of the eighth sternite are relatively long, the caudal margin of the sternite has tiny dents ( Figs 24–27 ).

Distribution ( Fig. 37 ). Zambezian Baikiaea woodlands in northeastern Botswana, Zambezian mopane woodlands in eastern Zimbabwe and southwestern Mozambique, Zambezian-Limpopo mixed woodlands in southwestern Zimbabwe, dry miombo woodlands in northeastern Zimbabwe, central bushweld and Limpopo lowveld in northeastern RSA.

Biology. Adults were collected from November to December and from February to March from an altitude of 125 to 1650 meters a.s.l. Preimaginal stages are unknown.

Etymology. The species is named in honor of Yahya Barham—a grandson of Prof. Dr. Dr. Edita E. Revay .
