Birketsmithiola kingstoni sp. n.

(Figs 8, 23)

Type material. Holotype (Figs 8, 23): “ Malawi: Central Region, | Nyika Plateau, | Chelinda camp. 2330m | S:10°35.295, E:33°48.754′ | 30.iii.2002 | AJ Kingston” / “Slide | AV6786 ♂ | A. Volynkin ” (ANHRT, ex AKW).

Diagnosis. The forewing length is 15.0 mm in the male holotype. Birketsmithiola kingstoni sp. n. is most externally reminiscent of B. bvumba sp. n. from which it differs in the red head (it is orange in the congener), the straighter costal margin of the forewing with a thinner red strip, and the hindwing having a broad area of grey suffusion along the costal margin, which is uniform pale yellow in B. bvumba sp. n. The male genital capsule structure of the new species is similar to B. kruegeri sp. n. but distinguished by the shorter valva (in proportion to the length of the tegumen-uncus complex), and the somewhat longer dorsal costal protrusion of the left valva. The phallus of B. kingstoni sp. n. is somewhat longer than in B. kruegeri sp. n. Compared to B. kruegeri sp. n., the vesica of the new species has a semiglobular subbasal diverticulum (it is absent in the congener), and the slightly larger medial cornutus positioned more laterally.

The female is unknown.

Distribution. The new species is known only from its type locality in northern Malawi (Fig. 34).

Etymology. The new species is dedicated to Mr Anthony J. Kingston, collector of the holotype specimen. The name is a noun in the genitive case.
