Type genus: Eremophlepsius Zachvatkin, 1924 .

Diagnosis

Eremophlepsiina are medium sized, robust, ivory or brownish leafhoppers. They are distinguished from other subtribes of Opsiini by the macropterous forewings, pygofer lobes with ventral pointed processes, valve thick and strongly developed, valve longer than wide and parabolically or lanceolate-parabolically shaped, subgenital plates without macrosetae, and aedeagal shafts arising from base.

Description

HEAD. Head subequal to, wider than, or distinctly narrower than pronotum. Discal portion of crown glabrous with radial or longitudinal striae. Anterior margin of head glabrous, irregularly textured, with numerous transverse striations. Frontoclypeus not tumid; texture shagreen. Clypellus widening 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.

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 present; 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 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; with short point of articulation with pygofer; thick and well-developed; longer than wide, parabolically or lanceolate-parabolically shaped. Pygofer dorsoapical margin incised to near mid-length; basolateral membranous cleft present; macrosetae well differentiated into several rows. Subgenital plates free from each other; articulated with valve; with thin hair-like setae or with macrosetae scattered, irregularly arranged. Style broadly bilobed basally, median anterior lobe pronounced. Basal processes of the aedeagus present, fused near base of aedeagus. Aedeagus without basal hinge; shaft divided near base, with two gonopores. Connective anterior arms somewhat divergent, Y -shaped; articulated with aedeagus.

FEMALE GENITALIA. Pygofer with numerous macrosetae. Ovipositor protruding far beyond pygofer apex. First valvula not strongly convex; dorsal sculpturing pattern strigate, concatenate, reticulate, or with rectangular shaped cells; sculpturing reaching dorsal margin; without distinctly delimited ventroapical sculpturing. Second valvula broad, gradually tapered; without dorsal median tooth; teeth on apical 1/3 or more; teeth small, regularly or irregularly shaped.
