Eponymy: Rudolf Hans ‘Ruud’ Wildekamp (1945–2019) was a Dutch aquarist and amateur ichthyologist who described at least twenty-seven fish species. [...] (Ref. 128868), visit book page.
Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce benthopélagique; non migrateur. Tropical; 20°C - 24°C (Ref. 2059)
Africa: Dja and Sangha drainages in Cameroon, Central African Republic and Republic of Congo (Ref. 47461). Also in the upper Ivindo (Ogooué River basin) in north-western Republic of Congo (Ref. 80395). Possibly also in the upper Likouala in Republic of Congo (see map in Ref. 47461), but this needs confirmation. Report from upper Sanaga questionable and unconfirmed in Ref. 80395.
