(Morgenthaler, 1934)

Acarapis dorsalis, is an external parasite infecting the dorsal groove of a honey bee's thorax. These mites are generally less than 175 micrometres (0.007 in) long, and can only be identified under a microscope.

A. dorsalis can be found exclusively along the dorsal scutoscutellar groove of its host bee's thorax.[1] These mites feed on the bee's haemolymph from here.

Two other parasitic bee mites resembling the tracheal mite are A. externus, and A. woodi.
