Lu, Lin & Zhang, Yalin, 2018, Taxonomy of the Oriental leafhopper genus Favintiga Webb (Hemiptera: Cicadellidae: Deltocephalinae: Drabescini) with description of a new species from China, Zootaxa 4370 (4), pp. 446-450 : 449

Favintiga paragracilipenis Lu & Zhang , sp. nov.

Length (including tegmen). Male: 6.5 mm.

Brownish yellow; forewing with small dark brown spot near middle of subcostal region, on apex of clavus and in apical cells; ocelli reddish ( Figure 2A–C, E ).

Crown produced parabolically with anterior margin angularly rounded to front and with some longitudinal striations on vertex and three carinae and two sutures medially ( Figure 2B ); ocelli located 4.0 times their diameter distant from eyes ( Figure 2C ); coronal suture extended to midlength of vertex, median length of vertex 1.5–2.0 times length next to eyes ( Figure 2B, C ); fore femur row IC with 11 setae ( Figure 2O ); apical setal formula of hind femur 2+2+1.

Male genitalia. Style moderately long with apex beak-like and filamentously tapered to apex, tenuous distally ( Figure 2M ). Connective Y-shaped, stem very long, 2.0 times length of arms, single process posteriorly on ventral surface strongly bifurcated, scissorlike ( Figure 2J ), directed ventrally and curved dorsad more strongly ( Figure 2J, L ). Aedeagus with dorsal atrium developed elongate and with one denticulate process on each side in caudal view ( Figure 2G, K ); with basal paired sinuate processes closer to shaft and directly articulating to connective ( Figure 2I ); shaft with slight basal dorsal bulge, curved dorsad and tapered to apex with long pair of basal processes, processes subapically expanded, tapered distally ( Figure 2F, L ).

Holotype: Male, China, Hainan Province, Jianfengling Mountains , 2008-05-07, 980m, Coll. Men Qiulei.

Etymology. The specific epithet “ paragracilipenis " indicates that this new species is very similar to F. gracilipenis .

Remarks. The new species is very similar to F. gracilipenis , but differs in the following characters: 1) style apical apophysis filamentously tapered to apex (more slender than in gracilipenis ); 2) connective with stem longer than apical process (process equal to stem in gracilipenis ); 3) process of connective directed ventrally and curved dorsad more strongly than the latter; 4) aedeagus with processes closer to aedeagal shaft on each side, subapically expanded, tapered to apex and slightly shorter than shaft in ventral and lateral view (more distant from shaft and nearly equal in length to shaft in gracilipenis ); and 5) shaft with slight basal dorsal bulge (absent in gracilipenis ).
