Type species. Rovnoxestus rasnitsyni sp. nov. here designated.
Etymology. The genus name, a masculine noun, was formed by combining the name of the fossil amber, Rovno, with an abbreviation of the name of a possibly related modern genus, Xestocephalus; from Greek: ξεστός, smooth, polished.
Diagnosis. The new genus differs from other fossil and modern cicadellid genera in having the following combination of traits: head slightly broader than pronotum with anterior margin slightly produced and rounded to face, ocelli on anterior margin well separated from eyes, lateral frontal sutures extended to ocelli; forewing fully developed, venation somewhat elevated and complete, appendix very narrow; hind wing well developed with submarginal vein narrowly separated from apical margin; front tibia with stout anteroventral seta near midlength; hind femur macrosetal formula 2+2+1, tarsomere I with elongate ventromesal seta at apex.
Rovnoxestus resembles Xestocephalites Dietrich & Gonçalves, 2014 from Eocene Baltic amber in overall habitus and in having a stout anteroventral seta near the midlength of the front femur, but differs in having the head wider than the pronotum, the pronotum relatively long, the hind femur macrosetal formula 2+2+1, and hind tarsomere I with an elongate ventroapical seta.
