The Microphysidae are a very small family of true bugs, comprising only 5 extant genera.
Systematics
Until recently, many authors considered these bugs to belong within the family Anthocoridae. A 2022 molecular phylogenetics study groups them with Joppeicidae in the proposed clade Microphysoidea. A 2023 study recovers them instead as relatively basal Cimiciformes.
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
