Agdistis vansoni View in CoL sp. n.

Figs 3, 4 View Figs 3, 4

Etymology:The species is named after Georg (Yuri) Stephanovich van Son (1898–1967), a famous South African lepidopterologist who collected numerous Pterophoridae .

Diagnosis: The new species resembles A. krooni in having a similar shape of the valvae and sternite VIII, but differs significantly from that and all other known species in a beak-shaped uncus and in the shape of the costal projections of the valvae.

Description:

Male.

External characteristics ( Fig. 3 View Figs 3, 4 ): Wingspan 21–27 mm (22 in holotype). Forewing ashy grey. Two black spots in distal part of forewing parallel to outer margin; another black spot closer to forewing base and posteriad of costal margin. Hindwing uniformly grey.

Male genitalia ( Fig. 4 View Figs 3, 4 ): Valvae asymmetrical with angular projections along costal margin. Left valva slightly narrowed distally and acute apically. Costal projection on left valva ends with strong brush-like plate with serrate outer margin. Right valva slightly narrowed distally and forms small incisions on cucullar side. Costal projection on right valva has strong serrated plate on upper edge, projection’s tip markedly narrowed. Uncus beak-shaped, strongly developed and bifurcated. Sternite VIII with oval-shaped incision. Lobes of stenite VIII rather long, noticeably narrowed distally.Aedeagus slightly longer than costal projection on right valva, apically slightly bent and tapering.

Female. Unknown.
