(Figs. 20, 21, 32, 51, 52)
Type material. Holotype, 3, UGANDA: Kabarole Distr.: Ruwenzori Mts., Nyakalengija 0o20.994’N 30o01.820’E, 1700 m., 10–11.xi.2007, L. Aarvik & M. Fibiger, genitalia slide L. Aarvik 2810 (NHMO). Paratypes: 233, same data as holotype, genitalia slide L. Aarvik 2809 (LA); 13, same data as holotype, genitalia slide L. Aarvik 2811 (NHMO). DEMOCRATIC REPUBLIC OF CONGO: 13, Congo Belge: P.N.A. Massif Ruwenzori, Riv. Katauleko, aff. Butahu, 2180 m., 28–29.vii.1952, P. Vanschuytbroeck & J. Kekenbosch, genitalia slide L. Aarvik 2010.002 (RMCA).
Description. Adult. Male (Figs. 20, 21). Head: Dark brownish black. Antenna dark brown. Labial palpus 1,5 times diameter of eye, brown, intermixed with black scales. Thorax: Dorsum and tegulae dark brownish black, light grey in middle. Fore and mid-legs dark grey, hind leg light beige; fore and mid-tarsi with paler rings; fore and mid-tibiae with basal, medial and distal light dots; hind tibia with beige scale tuft, hind tarsi with grey rings. Wingspan 21.0–24.0 mm. Forewing dark brownish grey, suffused with black in basal two thirds, shape of dorsal maculae and costal strigulae obscured by dark suffusion. Hindwing brownish grey, with single cilia line.
Variation. The description is based on the holotype. Two paratypes agree externally with the holotype, whereas the other paratypes (Fig. 21) have a more contrasting forewing pattern with a white dorsal maculae and a reddish suffusion.
Male genitalia (Figs. 51, 52). Dorsal edge of valva straight, shallowly concave between sacculus and cucullus, with cluster of spines at concavity, phallus (Fig. 52) 734–801 μm., tapered from middle, with ca. 20 small cornuti. Tergite 8 (Fig. 32) not incised laterally.
Female unknown.
Diagnosis. The male genitalia of D. sundi n. sp. differ from those of both D. kingstoni n. sp. and D. gilligani n. sp. by having fewer small cornuti in the phallus and the 8th tergite not laterally incised.
Distribution. Ruwenzori Mountains, both on the eastern Ugandan side and the western Congolese side.
Biology. The habitat is mosaic of mountain forest and small cultivated fields.
Etymology. The species is named after Karsten Sund, Natural History Museum, Oslo, who photographed the species treated in the present work.
Remarks. Additional males from Uganda externally resembling D. sundi n. sp. differ in the number of cornuti and the shape of 8th tergite. This material represents up to three undescribed species. Until more material becomes available, we refrain from describing these species. Some of these specimens were DNA barcoded (Fig. 78) and are denoted as Dracontogena sp. A, Dracontogena sp. C and Dracontogena sp. D.
