This paper describes a new species of Arctorthezia Cockerell (Hemiptera: Coccoidea:
Ortheziidae) from the Palaearctic region. The specimens were extracted from forest
litter in the collections of Muséum d’histoire Naturelle de Genève, Switzerland,
using Berlese funnels. Three further species, A. cataphracta (Olafsen), A. occidentalis
(Douglas) and A. pseudoccidentalis Morrison, are redescribed and re-illustrated.
The genus Arctorthezia now contains five species. An identification key, diagnostic
illustrations, photographs of un - mounted females and new locality records of the
Arctorthezia species currently known are provided.
