Kozár, F., & Konczné Benedicty, Z. 1999 Ortheziola (Homoptera: Coccoidea) of Africa with descriptions of new species.. Acta Phytopathologica et Entomologica Hungarica 34(1/2): 127-136.
Notes: Three new Ortheziola species are described from Africa. By these descriptions the number of the known Ortheziola species of the world increased to 20. Distribution records and zoogeographical considerations are given. One new species represents a link between Palaearctic and Ethiopian Regions. The data give a new insight about species richness of this genus. The new data indicate that this group needs further study in other regions of the world.
