| abstract | Larvae of Allothrombium (Acari: Trombidioidea) are ectoparasites of aphids and other arthropods. This paper reviews the systematics of larval Allothrombium. The larvae of 11 species of Allothrombium Berlese, 1903 (= Aphithrombium Childers and Vercammen-Grandjean, 1980; = Nippotrombium Southcott, 1986) are recognized, and a key to known species provided. Larvae of Allothrombium ovatum sp. nov., ectoparasitic on aphids in China, are described. Host records of larval Allothrombium mites, whenever known, are also given. |
