Prolivatis Emeljanov

Prolivatis Emeljanov, 1995: 781 ; 1996: 138–139. Type species: P. gorochovi Emeljanov, 1995 , by original designation.

Diagnosis. Small, brown to dark brown delphacids. Vertex quadrate, slightly wider at base than long, anterior margin of vertex rounded, projecting in front of eyes ( Figs 18 , 21 ), in profile rounded to frons ( Figs 19 , 22 ), submedian carinae originating from near base of lateral carinae, converging and meeting before apex of vertex, forming isosceles triangle at base of vertex ( Figs 18 , 21 ), Y-shaped carina with stem faint ( Figs 18 , 21 ). Median carinae of frons simple ( Fig. 20 ). Lateral carinae of pronotum sinuate, not reaching posterior margin ( Figs 18 , 21 ). Mesonotum with five carinae ( Figs 18 , 21 ). Antennal segments distinctly elongate ( Figs 18–20 ). Forewings with more or less continuous transverse veins before apical area, with well-defined bend of the membrane when wings are folded ( Figs 18, 19 ), forewings with 12 closed apical cells, Sc+R with two branches before subapical transverse nodal line ( Fig. 23 ). Post tibial spur spine-like, without teeth on inner margin ( Fig. 33 ), hind tibiae with 3 lateral teeth, metatarsomere I with five apical teeth, metatarsomere II with row of teeth, marginal teeth considerably longer than others. Male pygofer strongly excavated ventrocaudally, with large median process on midventral margin, lateroventral margin with lanceolate lobes ( Figs 25–28 ). Aedeagus 3-segmented, distal segment arched clockwise ( Fig. 31 ). Parameres slender and narrow, convergent apically ( Figs 25, 32 ). Anal segment with anterior margin sinuate, strongly produced at left side ( Figs 25, 35 ).

Remarks. Prolivatis is similar to Punana by the mesonotum having 5 longitudinal carinae, by the hind tibiae having 3 lateral teeth, by the forewings having 12 closed apical cells and by the Sc+R having two branches before subapical transverse nodal line. However, Prolivatis differs from Punana by its distinctly elongate antennae (reaching near apex of postclypeus, segment II about 2.3 times longer than I) (in Punana antennal segments short, at most reaching frontoclypeal suture, segment II a little longer than I); male pygofer having lanceolate lobe at each side of lateroventral margins (in Punana without lanceolate lobes) and laterodistal angle of male anal segment strongly produced at left side (in Punana not produced). Distribution. Southern China (Hainan Province) new record, Vietnam.
