Systematics: Subfamily: Pseudococcinae (Choi & Lee, 2022) Kiritshenko (1931) presented the name Longisomus in a list of coccoids, with collection data, but without dignosis either of the genus or species. Longisomus festucae Kiritshenko [NOMEN NUDUM], the single binomen listed by Kiritshenko in Longisomus, was regarded by Borchsenius (1949: 186) as indentical with Metadenopus festucae Sulc.
Structure: Body elongate, subparallelsided or oval. Antennae 6-segmented. Legs with shortened and thickened segments. Claw without denticle. Only posterior ostioles present. Discoidal pores of one type: multilocular. Tubular ducts very small (their length about half diameter of multilocular pore), with collar. Cerarii and conical setae absent. Both sides of body with flagellate setae. (Danzig & Gavrilov, 2013a)
General Remarks: Good definition and characters given by Borchsenius (1949), Tereznikova (1975), Kosztarab & Kozár (1988F), and by Tang (1992).
