Baits containing pyrrolizidine alkaloids (PAs) attracted 17 species of Gabonia and 1 of Nzerekorena in Kenya, East Africa. In Gabonia attraction is strongly male-biased (>>2600 males vs 27 females). Attempts to discover the beetles' hostplants were unsuccessful, but hosts of several other Coleoptera were recorded, including that of 1 Gabonia species not attracted to PAs. In addition to field-observations, the paper provides descriptions of 13 new species (12 Gabonia and 1 Nzerekorena), keys to the species, and a morphological characterization of peculiar structures in males.
