The Poronoticae are a group of oribatid mites possessing an octotaxic system, a series of glandular openings (most typically four pairs) on the notogaster in the form of porose areas or saccules. Monophyly of the group is uncertain; a number of taxa lacking the octotaxic system are otherwise similar in morphology to clearly poronotic species and it is probable that the octotaxic system has evolved more than once and/or been lost in some subgroups.

Members of the Poronoticae include the Achipterioidea, known from soil, litter, mosses and liverworts. Members of the Achipteriidae have characteristic spiral internal thickenings in the bothridium and a distinct long, thin, dorsally concave genu in leg IV (Norton & Behan-Pelletier 2009). The Epactozetidae are a Neotropical family with large, auriculate pteromorphs and foveate patterning on the notogaster (Norton & Behan-Pelletier 2009).
