Emeljanov, A. F. & Shcherbakov, D. E., 2020, The first Mesozoic Derbidae (Homoptera: Fulgoroidea) from Cretaceous Burmese amber, Russian Entomological Journal 29 (3), pp. 237-246 : 238

Tribe Derbachilini Emeljanov et Shcherbakov , trib.n.

TYPE GENUS: Derbachile gen.n .

DIAGNOSIS. Tegmina long (tegmen length greater than body length), shallowly tectiform in repose, with achilid-like venation, shallowly convex costal margin,longitudinal branches of M and CuA, CuA2 terminating on apical margin, apically truncate clavus about 1/2 wing length, and sensory pits on C. Hind wing with ScRA long, M forking before crossveins, and 3-branched CuA. Pedicel somewhat enlarged and flattened. Subantennal ridge low or absent. Apical segment of rostrum long.

COMPOSITION. Type genus and Achiderbe gen.n.

REMARKS. The new tribe combines the primitive structure of the hind wing and rostrum with a few characters of moderately derived Derbidae (sensory pits on C, enlarged flattened antennae). The type genus shows also the narrowed metope and primitive structure of pronotum and hind legs, and its type species, a rudimentary subantennal ridge. Such a character combination is unknown in other Derbidae (see Discussion).
