Résumé : A new species of Rubiaceae from the Democratic Republic of Congo, Keetia namoyae O. Lachenaud & Q. Luke, is described and illustrated. The species resembles Keetia tenuifora (Hiern) Bridson and Keetia mannii (Hiern) Bridson, but difers from both in having alternate (not opposite) fowering twigs with stif appressed hairs, few-fowered inforescences, a longer corolla tube, and larger fruits. The species is only known from the type locality in Maniema Province, and is assessed to be "Critically Endangered" according to IUCN Red List Categories and Criteria.
