Yellow mite

In Lorryia formosa, like all Acariformes mites, the capitulum is the head segment and the idiosoma is the body segment. The idiosoma is further subdivided into the propodosoma, metapodosoma, and opisthosoma. The Tydeinae subfamily, to which Lorryia formosa belongs, is characterized by having three pairs of lyrifissures (grooves that encircle the surface of an appendage) and a pair of primitive eyes (oculi) which commonly occur laterally on the propodosoma, the middle body segment to which the first two pairs of legs are attached. The genital region includes a progenital aperture flanked by setae. Specimens are generally less than 250 µm long.
