Fennah, 1950: 143; Chou & Wang, 1985: 199; Chen, Yang & Wilson, 1989: 35; Chou et al., 1999. Type species: Cixius flavisigna Walker, 1851 .

Description. The distinctive characters used by Fennah (1950), Chen et al. (1989) and Chou et al. (1999) are modified as follows.

Mid-sized species. Head with eyes distinctly narrower than pronotum. Vertex not declivous, broader across base than long in midline, produced before eyes about 1/3 of its length, median carina distinctly basally, obsolete distally, disk distinctly depressed, anterior margin carinate, angulately or roundly convex, triangular areolets at lateroapical angles of head distinct, lateral margins carinate, slightly foliate, diverging basad, posterior margin broadly concave. Frons slightly convex in lateral view, disk in midline longer than wide, basal margin truncate or slightly excavate, median carina percurrent, lateral margin carinate, slightly foliate laterad, sinuately diverging to below level of antennae then gradually incurved to suture. Clypeus with length in midline shorter than frons, tricarinae distinct. Rostrum reaching post-trochanter, with subapical segment shorter than apical segment. Antennae subglobose, not sunk in a depression. Ocelli separated from eyes. Eyes not, or slightly, overlapping pronotum, with lower margin not, or slightly, excavated. Pronotum in midline longer than, or same length, as behind eyes, anterior margin of disk convex-truncate, posterior margin subangulately excavated by about 115 degrees, median carina distinct, incomplete, lateral carinae slightly convex, twice as long as median carina, attaining hind margin, lateral lobe slightly inclined antero-ventrally, carinate between eye and tegula, ventral margins oblique. Mesonotum longer than vertex and pronotum combined, tricarinate, area between lateral carinae with one transverse callus at anterior third. Forewing with costal margin slightly convex, apical margin broadly convex, posterior margin with a reentrant angle of 155 degrees at apex of clavus, vein Sc+R forking proximally of Cu1 fork, slightly distal union of claval veins, clavus terminating slightly distad of middle of forewing. Post-tibiae with one lateral spine between basal 1/4 to 2/5, spinal formula 7-6-6 (5).

Male genitalia. Pygofer in lateral view with dorsal margin at least as long as ventral margin, anterior margin broadly concave; in ventral view medioventral process entire and not divided into two branches. Genital style with 2–3 processes rising from its dorsal margin, inner surface near base with a long process directed outwards. Phallobase sheath-shaped, incompletely or bilaterally asymmetrical; dorsal lobe with apical margin incised or angularly convex in the middle; ventral lobe shorter than dorsal lobe, with apical margin incised or cleft in the middle, 2 lateral lobes distinct or obsolete.

Distribution. Oriental and Palearctic regions.
