Type genus: Adama Dlabola, 1980 .

Diagnosis

Adamina are medium sized to large yellow, green, or black leafhoppers, sometimes with longitudinal reddish stripes (subgenus Adama ). They can be identified by the anterior margin of the head with 3 sharp carinae or with numerous irregular carinae, the aedeagus united to the connective only by a thin membrane, with long paraphyses (or "pseudostyles") usually articulated with or fused to the connective, and first valvulae widening apically, with irregular margins near the apex, and with reticulate sculpturing.

Description

HEAD. Head subequal to, wider than, or narrower than pronotum. Discal portion of crown glabrous with radial or longitudinal striae or shagreen.Anterior margin of head with 3 parallel carinae or with numerous irregular carinae. Frontoclypeus not tumid; texture shagreen. Clypellus widening apically. Clypellus apex following or slightly surpassing 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 ledge weakly developed (carinate or weakly carinate). Ocelli present; close to eyes; on anterior margin of head.

THORAX. Pronotum lateral margin carinate; lateral margin shorter than basal width of eye.

WINGS. Forewing macropterous; appendix restricted to anal margin; with 3 anteapical cells; veins not raised; without reflexed costal veins; A1-A2 crossvein present; apical venation highly reticulate or not reticulate.

LEGS. Profemur with AM1 and with one or more additional proximal setae; intercalary row with one row of five or more fine setae; row AV with relatively long macrosetae. Protibia dorsal surface rounded, convex. Metafemur apex macrosetae 2+2+1. Metatarsomere I not expanded apically; plantar setae simple, tapered.

MALE GENITALIA. Valve articulated with pygofer; lateral margin short, articulating with pygofer at a point. Pygofer basolateral membranous cleft present;macrosetae well differentiated into several rows.Subgenital plates free from each other; articulated with valve; without macrosetae. Style broadly bilobed basally, median anterior lobe pronounced. Basal processes of the aedeagus/connective present, connected or articulated to connective or near base of aedeagus. Aedeagus with single shaft and gonopore; dissociated from and lying far above connective, attached to connective only by thin membrane. Connective anterior arms somewhat divergent, U -shaped.

FEMALE GENITALIA. Pygofer with numerous macrosetae. Ovipositor protruding or not protruding far beyond pygofer apex. First valvula convex; margins irregularly undulate or notched subapically; dorsal sculpturing pattern strigate, concatenate, reticulate, or with rectangular shaped cells; sculpturing reaching dorsal margin; without distinctly delimited ventroapical sculpturing. Second valvula abruptly broadened medially or subapically; without dorsal median tooth; teeth restricted to apical 1/4 or less; teeth small, regularly or irregularly shaped.

Geography and ecology

Distribution:Afrotropical.Adamina are frequently collected at lights and likely feed in the forest canopy.

Remarks

Adamina contains the type genus, 4 subgenera, and 49 valid species. All members are found in the Afrotropical region.
