| abstract | Amphotrombium jenseni Zhang gen. & sp.nov. (Acari: Parasitengona) is described from a larva collected on an adult Fimbriaphis (Homoptera: Aphidae) feeding on Streptopus (Liliaceae) in Linn County, Oregon, USA. Standard notations for Acariformes designated by F. Grandjean were adapted and applied in the description. A new family, Amphotrombiidae is proposed for accomodating this genus. A key to superfamilies of larval Parasitengona is provided. |
