Type genus: Circulifer Zachvatkin, 1935.

Diagnosis

Circuliferina are relatively small and slender ivory, greenish, or brownish leafhoppers. They are distinguished from other subtribes of Opsiini by their relatively small, slender shape, mesal margin of eye notched, forewing macropterous, subgenital plate with a lateral row of macrosetae, valve normal, aedeagus bifurcate apically with branches forming semicircles, and ovipositor not protruding far beyond pygofer apex.

Description

HEAD. Head subequal to or wider than pronotum. Discal portion of crown glabrous with radial or longitudinal striae. Anterior margin of head shagreen. Frontoclypeus not tumid; texture shagreen. Clypellus parallel-sided or tapering apically; 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 ledges absent. Ocelli present; close to eyes; on anterior margin of head. Mesal margin of eye notched.

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; with or without reflexed costal veins; A1-A2 crossvein absent; apical venation not highly reticulate.

LEGS. Profemur with AM1 seta only; intercalary row with one row of five or more fine setae; row AV with short, stout setae. 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; with short point of articulation with pygofer. Pygofer basolateral membranous cleft present; macrosetae well differentiated into several rows. Subgenital plates free from each other, articulated with valve; macrosetae uniseriate laterally. Style broadly bilobed basally, median anterior lobe pronounced. Basal processes of the aedeagus/connective absent. Aedeagus without basal hinge; shaft divided toward apex, with two gonopores. Connective anterior arms somewhat divergent, Y -shaped; articulated with aedeagus.

FEMALE GENITALIA. Pygofer with numerous macrosetae. Ovipositor not protruding far beyond pygofer apex. First valvula convex; dorsal sculpturing pattern granulose, maculose, or imbricate (with overlapping scales); sculpturing reaching dorsal margin; without distinctly delimited ventroapical sculpturing. Second valvula slender throughout; without dorsal median tooth; teeth on apical 1/3 or more; teeth small, regularly or irregularly shaped.
