Metadenopsis is now Paratrionymus Borchsenius, 1948 (Pseudococcidae)

Paratrionymus Borchsenius 1948c: 582. Type species: Ripersia halocharis Kiritshenko by original designation . (= Paratrionymus halocharis, (Kiritshenko, 1932) ) 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)
Structure: Legs normally developed; claw without denticle. Claw digitules not widened apically. 2 pairs of ostioles present. Anal ring strongly simplified, with several pores and 6 short setae. Multilocular pores and simple pores present. Trilocular pores absent. Tubular ducts not numerous or absent. Cerarii absent. Conical setae and spinulae absent or singular. Both sides of body with flagellate setae. (Danzig & Gavrilov, 2013a)
General Remarks: Good definition and characters of the adult female given by Borchsenius (1948c, 1949) and by Tang (1992).
