ABSTRACT. Derbachile hochae gen. et sp.n., D. aschei sp.n. and Achiderbe obrienae gen. et sp.n. from mid-Cretaceous Burmese amber described in Derbachilini trib.n. are the first Mesozoic and the earliest fossil Derbidae. D. hochae sp.n., with 2.6 mm tegmina, is one of the smallest derbids known. Like their modern relatives, Burmite derbids could feed on monocots and woody dicots, and their nymphs could dwell in rotting wood and plant debris. Transformation of achilid-like ancestors into typical derbids is discussed. The new tribe combines achilid facies of primitive derbids with some characters of more advanced tribes, such as sensory pits on the costal vein in tegmen, narrow face, flattened antennae and subantennal carina. The tribe is assigned to the primitive subfamily, which is renamed Breddiniolinae Fennah, 1950, stat.n. (= Cedusinae Emeljanov, 1992, syn.n.) by priority.
KEY WORDS: planthoppers, Achilidae, sensory pits, phylogeny, fossil, Cenozoic.
