Lectotypus (designated here): EQUATORIAL GUINEA. Fernando Po [Bioko]: 323 m, 1860, Mann 310 (K [K000042912] image seen; isolecto-: P [P00300432] image seen) . Syntypus: EQUATORIAL GUINEA. Fernando Po [Bioko]: 1861, Mann 1155 (K [K000042911] image seen) .

Notes. – This species is found in Nigeria, Liberia, and Bioko in Equatorial Guinea, and its subspecies have separate ranges (VERDCOURT, 1977). The name Psychotria insidens was based on collections made by Mann in Bioko and deposited at K, which VERDCOURT (1975: 269) detailed as the syntypes Mann 310 and Mann 1155. This name has apparently not been typified further, so a lectotype is designated here. The collection Mann 310 has more label data, a duplicate deposited in another herbarium, and mature flowers and it is here designated the lectotype. The other syntype Mann 1155 has immature fruits.
