Eucosma deltozyga Meyrick, 1928: 440 .

Fulcrifera deltozyga, Razowski & Krüger 2007: 132, figs. 129, 251.

Material: 3, MALAWI: Nyika Plateau, S of Vitintiza Hill, Sambara River, 1700 m., Brachystegia forest , 15.x.1996, W. Mey & M. Nuss, genitalia slide L. Aarvik 2007.010 (ZMHU) .

Description. Adult. Male (Fig. 22). Head: Dark brownish black. Antenna dark brown, scape white above. Labial palpus 1,5 times diameter of eye, brownish black. Thorax: Dorsum and tegulae black, with broad white band in middle and white posterior tuft. Fore and mid legs black, hind leg beige; fore and mid tarsi with white rings; fore and mid tibiae with basal, medial and distal white dots; hind tibia with beige scale tuft, hind tarsi with grey rings. Wingspan 17.0–20.0 mm. Forewing black, suffused with brown in tornal area, dorsal white maculae rounded, outer macula with dark brown strigulae on dorsum; costal strigulae distinct; white patch at termen below apex; cilia grey with white patch below apex. Hindwing brownish grey, with single cilia line.

Male genitalia (Figs. 53, 54). Valva with broad cucullus, strongly widened dorsally; between sacculus and cucullus shallowly concave, phallus (Fig. 54) 653 μm. (n=1), broadest in middle, with ca. 50 small cornuti. Tergite 8 (Fig. 33) short, incised laterally.

Female genitalia (Figs. 72, 73). We tentatively identify the following two females from Malawi as D. deltozyga: Central Region, Lilongwe District: Ntchisi Forest Reserve, 1Ƥ, 18.ii.2004, L. Aarvik, genitalia slide L. Aarvik 2737 (LA); 1Ƥ, 12.xii.2002, D.J.L. Agassiz, genitalia slide T. Karisch 2244 (DA). Sternite 7 with deep Ushaped excavation; sterigma large, strongly sclerotised posteriorly; ductus bursae with weak internal sclerite near ostium; paired oval sclerites posterior of sterigma large, dish-shaped, overlapping with posterior edge of sterigma, ductus bursae with weak internal sclerite near ostium.

Diagnosis. The presence of a dorsal process on the phallus is diagnostic for this species.

Distribution. Republic of South Africa and Malawi.

Remarks. D. deltozyga was described from a single male from Transvaal, Rep. S. Africa (Meyrick 1928). The type was examined by Razowski & Krüger (2007) who figured the wings and genitalia. These authors placed the species in the genus Fulcrifera Danilevsky & Kuznetsov, 1968 . This decision was obviously based on the presence of a small dorsal process on the phallus. We transfer the species to Dracontogena based on the typical wing pattern and the male genitalia that resemble other species of Dracontogena . We will not speculate whether the dorsal process on the aedegus of D. deltozyga is homologous with the fulcrum in Fulcrifera species. We identify the male from Malawi as D. deltozyga based on the male genitalia, viz. the shape of cucullus and the presence of the dorsal process on the phallus.
