Type genus: Koebelia Baker, 1897 .

Diagnosis

Koebeliina are medium sized to large brown leafhoppers. They are distinguished from Grypotina by the crown strongly produced, spatulate, anterior margin of head foliaceous, forewing veins pustulate, appendix absent, metatibia dorsal rows without or with indistinct intercalary setae, metatibia pecten with platellae, first valvula relatively straight and not strongly curved, first valvula dorsal sculpturing pattern reticulate to maculose and submarginal, and second valvula with teeth restricted to apical 1/4.

Description

HEAD. Head subequal to or wider than pronotum. Discal portion of crown shagreen. Anterior margin of head foliaceous. Frontoclypeus not tumid; texture shagreen. Clypellus narrow; parallel-sided or tapering apically; apex extending well beyond normal curve of gena. Lorum subequal to or wider than clypellus near base. Antennal bases near middle or posteroventral (lower) corners of eyes. Antennae short, less than 1.5 x width of head. Gena obtusely incised laterally; with fine erect seta beside laterofrontal suture. Antennal ledges absent. Ocelli present; distant from eyes; on face.

THORAX. Pronotum lateral margin not carinate; lateral margin shorter than basal width of eye.

WINGS. Forewing macropterous or submacropterous; appendix absent or reduced; with 3 anteapical cells; veins not raised or slightly raised; veins pustulate; without reflexed costal veins; A1-A2 crossvein absent; apical venation not highly reticulate.

LEGS. Profemur with AM1 seta only; intercalary row reduced or absent; row AV with relatively long macrosetae. Protibia dorsal surface flat, AD and PD margins at ~90º angles but not carinate. Metafemur apex macrosetae 2+1 or 2+2. Metatarsomere I not expanded apically; plantar surface with one or more platellae.

MALE GENITALIA. Valve articulated with pygofer; with short point of articulation with pygofer. Pygofer basolateral membranous cleft present; macrosetae absent or reduced (≤ two rows). Subgenital plates free from each other, articulated with valve; macrosetae scattered, irregularly arranged. Style broadly bilobed basally, median anterior lobe pronounced. Basal processes of the aedeagus/connective absent. Aedeagus with large apical process arising from ventral margin; without basal hinge; with a single shaft and gonopore. Connective anterior arms somewhat divergent, Y -shaped; articulated with aedeagus.

FEMALE GENITALIA. Pygofer with macrosetae reduced or absent. Ovipositor protruding or not protruding far beyond pygofer apex. First valvula not strongly convex; dorsal sculpturing pattern reticulate or maculose; sculpturing reaching dorsal margin or submarginal; without distinctly delimited ventroapical sculpturing. Second valvula broad, gradually tapered or slender throughout; without dorsal median tooth; teeth restricted to apical 1/4 or less; teeth small, regularly or irregularly shaped.
