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 tenuiflora (Hiern) Bridson and Keetia mannii (Hiern) Bridson, but differs from both in having alternate (not opposite) flowering twigs with stiff appressed hairs, few-flowered inflorescences, 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.
