Acarophenacidae is a family of mites in the order Trombidiformes that are egg parasitoids and ectoparasites of beetles or thrips. [1] It contains eight genera and around 40 species. [2]
Acarophenacidae are <200 μm in length and elongate to oval in shape. Distinguishing features are the gnathosoma (mouthparts) partially/completely fused into the propodosoma, indistinct palps and the first leg pair being thickest. [1]
Acarophenacidae have a reduced life cycle, in which the larvae complete their development within their mother; the entire life cycle can take only 4–5 days. [1]
Some Acarophenacidae have been suggested as biological control agents as they reduce populations of their hosts. These include Acarophenax mahunkai for the lesser mealworm ( Alphitobius diaperinus ), [3] and Acarophenax lacunatus for red flour beetle ( Tribolium castaneum ) and lined flat bark beetle ( Cryptolestes ferrugineus ).
