Six new species of Laboulbeniales occurring on termiticolous Carabidae from Guinea and Cote d'Ivoire are described. Four new species are in the genus Laboulbenia: (1) L. procleti, parasitic on Procletus minor, (2) L. claudei and (3) L. strigomeri parasitic on Strigomerus spp., and (4) L. nimbaensis, parasitic on Lophidius testaceus, Paralophidius septentrionalis, Somoplatodes kuntzeni and Somoplatus spp. Two are in the genus Rhachomyces: (1) R. lamottei, parasitic on Eunostus chappuisi, and (2) R. oraeborensis, parasitic on Somoplatus spp. and Paralophidius septentrionalis. Four of the species are polymorphic: L. nimbaensis, L. strigomeri, R. lamottei, and R. oraeborensis. Rhachomyces schweitzeri, parasitic on Lophidius testaceus, Somoplatodes kuntzeni and Somoplatus spp. is newly reported, as it was previously only known from the type collection.
