Material examined. Holotype of Eucosma tonitrualis, 3, Sao Tomé, 5.xi.1932, W.H.T. Tams, genitalia slide BMNH 7012 (BMNH).

Diagnosis. Wingspan 17.0 mm. Together with D. niphadonta characterised externally by the combination of a strongly notched hindwing and a patch of black sex scales. The other African species with a patch of black sex scales on the hindwing upperside, D. solii n. sp., has the hindwing termen only slightly concave. The male genitalia of D. tonitrualis differ from all other Dracontogena species by the slender cucullus (Fig. 45).
