Description. Holotype male (Figs. 1, 3, 4, 6, 7, 17). Total length 32 mm; width across humeri 14.5 mm. Colour: Head (except clypeus), pronotum, scutellum, pygidium, legs, and venter green with weak red reflections. Elytra yellow with dark green band at the disc ending in black humeral and apical maculae; humeral and apical maculae elongate to midpoint of elytral band, not abutting; elytral suture black with green border reduced from scutellum towards elytral apices; elytral margin black. Clypeus tawny and green iridescent at base. Head: Frons posteriorly smooth with fine, sparse punctures becoming densely punctate near lateral and anterior margins; small and large punctures mixed; lateral margin with short, tawny setae. Interocular width equals 5.5 transverse eye diameters. Clypeus ending in a narrowly forked horn with black tips (Fig. 17); width of clypeal fork 2.9 mm; external tubercles bilateral of the clypeal horn ending in transversely blunt apices (Fig. 17). Labium moderately deeply punctate, setigerous; setae long, tawny (Fig. 4). Pronotum: Surface evenly convex in lateral view; sparsely punctate at disc and densely punctate towards margins. Scutellum: Surface sparsely punctate, punctures small. Elytron: Surface punctate; punctures small and dense; 1 row of moderately large punctures adjacent to suture. Pygidium: Disc regularly convex in lateral view; surface rugose with sparse punctation (Fig. 7); setigerous; setae short, tawny. Venter: Mesosternal apex produced; abdominal ventrites 1 to 5 with longitudinal impression. Legs: Colour of the body; protibia denticulate at interior margin; metatibia half green, apically tawny; metatarsi reddish brown, others black (Fig. 1). Parameres: Form symmetrical (Fig. 6). Wings: transparent, tawny with a dark brown bar close to the tip (Fig. 3).
Allotype. Female (Figs. 2, 5, 8). Total length 29.5 mm; width across humeri 14 mm. Colour: Same as in the holotype. Elytra with elongate humeral and rounded, apical maculae; Clypeus tawny with green iridescence. Head: Frons posteriorly with fine to medium, sparse punctures becoming densely, confluently rugopunctate at disc and margins; small and large punctures mixed; lateral margin with short, tawny setae. Interocular width equals 5.0 transverse eye diameters. Clypeus unarmed; Labium rugose (wavy ridges) with both small and deep, large punctures, setigerous; setae long, tawny (Fig. 5). Pronotum: Surface evenly convex in lateral view; sparsely punctate. Scutellum: Surface with small punctures evenly distributed and moderately large punctures sparsely distributed. Large deeper punctures at the anterior margin. Elytron: Surface punctate; punctures small, dense; three parallel rows of large punctures between suture and discal green band. Pygidium: Disc evenly convex in lateral view; surface highly rugose-reticulate without punctation (Fig. 8); setigerous; setae short, tawny. Venter: Mesosternal apex produced; abdominal ventrites without impressions. Legs: Colour of the body; metatibia half green, apically tawny; metatarsi reddish brown, others black. Wing: Same as in holotype.
Paratypes. Male (n = 8). Total length 24–34 mm. Width across humeri 11.0– 14.8 mm. The paratypes from Budongo (Uganda), Semuliki Forest (Uganda), Kisogo (Uganda), and the Taita Hills (Kenya) possess the same appearance as the holotype. Humeral and apical maculae vary in length. Width of clypeal fork: 1.9–2.9 mm. The paratype from Kampala (Uganda) differs in colour; the discal band on the elytron is brighter, the maculae are brown. All legs are reddish brown. Female (n = 2). Total length 30.5–31.0 mm. Width across humeri 14 mm. The paratypes possess the same appearance as the allotype. In one specimen all tarsi are reddish brown.
Diagnosis. This species can be distinguished from other Eudicella (Eudicella) species based on the following combination of characters: clypeus tawny and green iridescent at its base; clypeal fork short and narrow (Fig. 17); pygidium rugosely sculptured (Figs. 7–8); labium deeply punctate in males (Fig. 4) and rugose in females (Fig. 5); wings transparent, tawny with a dark brown bar close to the tip (Fig. 3). Furthermore, the form of the parameres is unique for E. nana and E. darwiniana and can be distinguished from the other species in the genus (Fig. 6).
Etymology. The species name is derived from the Latin word for dwarf (nanus) as it is the smallest species in the subgenus Eudicella.
