The Microphysidae are a very small family of true bugs, comprising only 5 extant genera.

Systematics

female *Loricula* sp. (<2 mm) from Cologne, Germany

Until recently, many authors considered these bugs to belong within the family Anthocoridae.^{[citation needed]} A 2022 molecular phylogenetics study groups them with Joppeicidae in the proposed clade Microphysoidea.^[1] A 2023 study recovers them instead as relatively basal Cimiciformes.^[2]

The following genera belong to this family:

Subfamily Microphysinae

Genus Chinaola Blatchley
Genus Loricula Curtis (= Microphysa)
Genus Mallochiola Bergroth
Genus Myrmedobia Bärensprung
Genus †Myrmericula Popov
Genus †Popovophysa McKellar & Engel 2011, Canadian amber, Campanian
Genus †Tytthophysa Popov & Herczek 2009 Baltic amber, Eocene

Subfamily Ciorullinae

Genus Ciorulla Péricart
