Type species: Empoasca okubella Matsumura, 1931 .

Diagnosis. Body robust ( Figs 1, 2 ). Head including eyes narrower than pronotum ( Figs 1, 3 ). Coronal suture distinct, extending beyond crown midlength ( Figs. 1, 3 ). Face short, convex in lateral view, lateral frontal suture distinct; anteclypeus slightly convex, not expanded ( Fig. 4 ). Pronotum large ( Figs 1, 3 ). Forewing narrow, rounded apically, apical cells occupying nearly one-fourth total length, veins R2 and RM dissociated at their bases, both arise from r cell; MCu arising from m cell, c and r cells nearly equal in width, both narrower than m and cua cells ( Fig. 5 ). Hindwing with CuA unbranched ( Fig. 6 ). Front femur seta AM1 stout, situated near ventral margin; intercalary row with two large basal seta and five smaller setae more distad. Hind femur with macrosetal formula 2+1+1. Hind-tibia row AV with five preapical macrosetae.

Male 2S abdominal apodemes well developed ( Fig. 7 ). Male pygofer elongate, apical half narrowed to apex, bearing few rigid microsetae on each side of lobe and few additional rigid microsetae on ventral margin, ventral appendage present( Fig. 8 ). Subgenital plate surpassing pygofer lobe, darked apically, basal setae poorly differentiated, marginal setae well-developed, almost continuous along entire length of dorsolateral margin of plate, macrosetae starting at one-fourth distance from base arranged in two rows, apical setae in one row, feeble microsetae sparse ( Figs 8, 9 , 17 ). Style bearing few apical teeth and microsetae ( Figs 15, 16 ). Aedeagus with preatrium present, usually long and somewhat arcuate; shaft tubular, well sclerotized, curved dorsad, without processes; gonopore ventrad at apex ( Figs 8 , 12, 13 ). Anal tube weakly sclerotized, with basolateral appendage variably developed ( Figs 8 , 10, 11 ).

Distribution: China (Yunnan and Zhejiang Provinces), Japan.
