Family Dorytocidae Emeljanov et Shcherbakov , fam. n.

Type genus: Dorytocus Emeljanov et Shcherbakov , gen. n.

DIAGNOSIS. Small planthoppers. Eumetope without intermediate carinae (for planthopper cranium nomenclature, see Anufriev & Emeljanov, 1988; Emeljanov,

1996, 2001). Rostrum long. Pronotum inverted V-shaped, its disc much displaced anteriorly and deeply incised posteriorly. Legs slender; hind tibia without lateral teeth, with asetigerous apical pecten; hind tarsal pectens setigerous. In nymphs:

median carina of pronotum double; lateral carinae of mesonotal disc running along posterior pronotal margin; disc of meso- and metanotum with sensory pits; fore and mid tibia foliaceous; dorsum of abdomen carinate, without wax-pore plates, with long segments IX and X not retracted between lateral lobes of segment VIII.

COMPOSITION. Type genus.

REMARKS. In many characters similar to Cretaceous Perforissidae , being distinct in the longer legs and rostrum, asetigerous hind tibial pecten, at nymphal stage in the carinate dorsum of abdomen and foliaceous tibiae, and in the elongated head of the type (and only known) genus. In Perforissidae the head, rostrum and legs are short, tibiae not foliaceous, the hind tibial pecten is setigerous; in perforissid nymphs the median carina of pronotum is single, and the dorsum of abdomen ecarinate. The abdominal segments IX–X are well developed, not retracted between lateral lobes of the segment VIII in nymphs of Perforissidae and Dorytocidae fam.

n., whereas in nymphs of other fulgoroid families the segment X is reduced or absent, and the segment IX is often retracted.
