ABSTRACT. Psilargus anufrievi gen. et sp.n. (Psilarginae subfam.n.) from mid-Cretaceous Burmese amber is assigned to the family Jubisentidae in basal (pre-cixioid) Fulgoroidea. The two formerly known genera of this family are placed in Jubisentinae stat.n. The only known specimen of the new species is a minute female with extremely shortened wings. It is the earliest recorded instance of extreme brachyptery in Auchenorrhyncha. All known Jubisentidae were flightless, camouflaged, and likely associated with herbs in the Burmese Cretaceous tropics.
KEY WORDS: planthoppers, Perforissidae, wing dimorphism, brachyptery, sensory pits, phylogeny, fossil, host plants, grasses, camouflage, mimicry.
