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]
