Ripe fruits of Chytranthus obliquinervis were sampled from a tree in Buda Forest in coastal Kenya. Four species of insects were reared from the fruits, two species of Tephritidae, an undescribed species of gelechiid moth, and a new species of tortricid moth, Grapholita chytranthusi Razowski, sp. n., described herein. No parasitoids were reared. Notes on the biology, distribution, and conservation status of the host and its pests are included.
