Genus Euriphene: There have been five species of the genus Euriphene so far recorded from Semuliki. E. doriclea has been reported from Semuliki (Williams, 2022), although it has never been sampled in the fruit-feeding traps and was not included in the checklist publication (Forbes, 2018 ). It has been recorded from the DRC Semliki Valley and the Ituri Forest of the DRC (Ducarme, 2018). These five species contribute to around 40% of Uganda's 12 Euriphene species total, although E. barombina (included in the Davenport Uganda checklist) was recorded in error. E. saphirina (found at Semuliki) replaces E. barombina within the Congo Basin and comprises the species at the eastern extent of its range distribution. The occurrence of three of the species; saphirina, ribensis and atossa in traps was uncommon while only one specimen, a female E. amaranta, has been observed in flight and never sampled in traps. All five species of Euriphene recorded at Semuliki are environmentally sensitive and thrive in forests with good canopy cover and in good condition (undegraded).
The following museum images are taken from The Royal Museum of Central Africa, Tervuren in Belgium and portray the male (left column) and female, both upper and underside. There was only one specimen of Euriphene amaranta at Tervuren, the specimen below was taken from Entomology Collections, Natural History Museum, London.

Field Images: There are field images for all but one of the recorded species at Semuliki: E.amaranta. This has been recorded at Semuliki (then Bwamba Forest): the specimen's identity has been verified and it is stored at at The Hunterian Museum, University of Glasgow in Scotland. This species appears very rare throughout its range.
