03F587AA30205A07FF5CFF56FBF1A68E.taxon	discussion	Remarks: Although Okubasca resembles Empoasca (s. s.) in size, coloration and body proportions, it differs in several important respects, including: male pygofer lobe with additional rigid microsetae at ventral margin (Figs 10, 12, 27, 29), ventral pygofer appendage short (Figs 10, 12, 27, 29); subgenital plate apex strongly tapered, apex fuscous, with rigid marginal setae (group B) extended along nearly entire outer margin, group A not differentiated (Figs 11, 28); aedeagus with preatrium well developed but little or no longer than shaft and forming angle of 90 º or less with shaft in lateral view (Figs 14, 15, 31, 32) (Dworakowska, 1982; Liu et al., 2011). All mentioned characteristics are unique and stable, so we proposal to elevate Okubasca to status as a separate, valid genus.	en	Yu, Xiaofei, Yang, Maofa (2019): Okubasca Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) elevated to separate genus status with description of two new species from China.
