Neaspasia malamigambo Aarvik , new species

( Figs. 8 , 24 , 34 )

Type material. Holotype, ♂, UGANDA: Rakai Distr.: Sango Bay , Malamigambo Forest, 1140 m , 0 0o 55,796’S 31o 37,287’E, 1–2.xi.2007, L. Aarvik & M. Fibiger, genitalia slide NHMO 2303 ( NHMO); Paratypes, 5♂♂, 1♀, same data as holotype, genitalia slide ♂ L. Aarvik 2847, genitalia slide ♀ NHMO 2284 ( NHMO).

Description. Male ( Fig. 8 ). Head: Cream, neck tufts brownish black. Antenna brownish black, scape cream. Labial palpus ca. 1.8 times diameter of eye, cream, externally with some light brown suffusion, third segment drooping. Thorax: Brownish black. Fore- and mid-legs grey externally, beige internally, with light rings; hind leg light beige, with grey suffusion, tibia pencil light ochreous. Wingspan 12.0–14.0 mm. Forewing upperside basal third brownish black, distal two thirds white; median fascia represented by olive-grey suffusion on costa and in middle; round patch of olive-grey suffusion also present in subapical area and at tornus; some black scales present along costa, at tornus and subapically; cilia grey, becoming lighter towards tornus. Hindwing light grey, lighter towards base; cilia light grey, becoming lighter towards anal corner; rhopaloid scales present at anal corner. Abdomen: Grey, anal tuft beige. Genitalia ( Fig. 24 ). Uncus concave on lateral sides; cucullus of valva with several strong teeth along ventral edge, ventral lobe without single conspicuous tooth¸ group of spines between caudal edge of sacculus and basal excavation form a relatively narrow band; phallus slender, evenly curved, becoming gradually narrower.

Female. Head and Thorax: Essentially as described for male, except single female larger than males, wingspan 14.5 mm; hindwing darker, lacking anal roll and rhopaloid scales.

Abdomen: Genitalia ( Fig. 34 ) with sterigma rounded; anterior third of ductus bursae membranous, broad; sclerite at origin of ductus seminalis small.

Diagnosis. Externally N. malamigambo is distinguished by the light forewing cilia and the olive grey patches in the distal light part of the wing. The male genitalia are characterised by the relatively narrow band of spines on sacculus. In the female genitalia the long, broad membranous portion of ductus bursae with a small sclerite is diagnostic.

Distribution. The species has been collected in Uganda, close to the Tanzanian border.

Ecology. The habitat is forest.

Etymology. N. malamigambo is named after the type locality, Malamigambo Forest.
