Metadenopsis is now Paratrionymus Borchsenius, 1948 (Pseudococcidae)

Paratrionymus Borchsenius 1948c: 582. Type species: Ripersia halocharis Kiritshenko by original designation . accepted valid name
Metadenopsis Matesova 1966: 98. Type species: Metadenopsis halogetonis Matesova by original designation . junior synonym (discovered by DanzigGa2015: 335)

Systematics: Subfamily: Pseudococcinae (Choi & Lee, 2022) In the description of the genus, Paratrionymus, Borchsenius erroneously noted the presence of 3-locular pores and 3 pairs of cerarii in adult females. These mistakes may have provoked Matesova to describe a new genus, Metadenopsis. Danzig & Gavrilov-Zimin (2015) compared the type material of the two genera and ascertained that the species are identical except for the presence of a few tubular ducts in M halogetonis and none in Ripersia halocharis. (Danzig & Gavrilov-Zimin, 2015)
General Remarks: Good definition and characters of the adult female given by Borchsenius (1948c, 1949) and by Tang (1992).
