Abstract: | Nine species of the family Phacopteronidae are recorded from Cameroon. All are assigned to the large pan‐tropical genus Pseudophacopteron. Eight species are described as new, and P. electum Capener is redescribed. The species are diagnosed and illustrated, and keys for the identification of adults and fifth instar larvae are provided. Information is given on distribution, host plants, and biology. Eight species are associated with plants of the order Rutales/Sapindales (three Sapindaceae, one Burseraceae, one Burseraceae or Anacardiaceae, one Meliaceae, one Rutaceae, and one Anacardiaceae/Simaroubaceae); host plants of one species remain unknown. Four species, namely P. electum, P. fuscivenosum sp. n., P. lecaniodisci sp. n., and P. morion sp. n., induce nut or pit galls on the leaves. |
