A new species from Liberia and Co\ˆte d\’Ivoire, Chassalia bicostata O. Lachenaud \& Jongkind, is described and
compared with its two close relatives, C. pteropetala (K. Schum.) Cheek and C. pleuroneura (K. Schum.)
O. Lachenaud, both from central Africa. The latter is here transferred to Chassalia from Psychotria. All three species
share deeply bifid stipules, which are an unusual feature in Chassalia. Full descriptions and illustrations are given for
the three taxa.

Background A novelty is described in the framework of an ongoing revision of Psychotrici in West and Central Africa. Methods Normal practises of herbarium taxonomy have been applied. Key results Psychotria sonkeana O.Lachenaud \& Sene, a new species endemic to southern Cameroon, is described and illustrated. Belonging to section Confertiflorae, it is related to P. subobliquct Hiern and P globiceps Hiern, but differs from both in having fistulose branches, puberulent peduncles and green-andwhite-striped immature fruits. The species is assessed to be Endangered according to the IUCN criteria.
