Type species. Ectropona dargei Kurshakov & Zolotuhin, 2013 (by original designation)

Holotype. Male.

Type locality. Usambara Mountains , Tanzania ( MWW).

Genus re-description. Small size. Antennae bipectinate, beige or pinkish-brown. Ground colour of head, thorax, abdomen and wings beige or pinkish-brown speckled with a few indistinct dark brown scales. Forewing broad, rounded; discal spot rounded. Postmedial line grey to dark brown, sharply angled at vein R5. Distal margin grey or dark brown, fringe long, generally slightly darker than ground colour. Hindwing rounded, scalloped near anal margin; postmedial line gently arcuate. Fringe long, slightly darker than ground colour, cilia sometimes dark grey in distal quarter. Underside. Ground colour and legs beige or pinkish-brown, hindtibia with two pairs of spurs. Ground colour of wings as upperside, postmedial lines widely convex. Forewing discal spot visible, and discal marking on hindwing also sometimes present. Male genitalia. Single posterior process of transtilla broad triangular; no anterior processes. Valve wide at base, triangular, tapering to a rounded point distally. Phallus very short, with slight curve and large vesica with a single long or group of short cornuti.

Diagnosis. Species of Ectropona and Pseudectropona both share a very similar habitus with the postmedial line of the forewing sharply angled at vein R5. However, these two sibling genera can easily be separated based on the absence of anterior processes of the transtilla and the broad triangular valves lacking a saccular process in Ectropona .

Distribution. Restricted to mountainous regions of eastern Tanzania and south-eastern Kenya.
