A new species of Eudicella White, 1839 (Coleoptera: Scarabaeidae: Cetoniinae), is described from Uganda and Kenya: Eudicella nana new species. Morphological and genetic analyses of the new taxon and phenotypically allied species are given. Eudicella nana is compared with its hypothesized sister species, E. darwiniana Kraatz, 1880, and diagnostic characters that distinguish it from other species occurring in the same region are provided.

Eudicella (Eudicellanana Seidel, 2016

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.
