Xu, Deliang & Zhang, Yalin, 2022, Taxonomy of the leafhopper genus Favintiga (Hemiptera: Cicadellidae: Deltocephalinae: Drabescini) with description of a new species from China, Zootaxa 5222 (4), pp. 395-400 : 397

Favintiga polyacantha sp. nov.

( Figs. 1 , 2 )

Description. Body length (including tegmina), male: 4.8–5.1 mm, female: 5.2 mm.

Body color tawny. Crown ( Fig. 1 , A, B) yellow, extended to pronotum. Face ( Fig. 1 , C) yellowish. Scutellum ( Fig. 1 , A, B) with near middle and hind region yellow. Forewing ( Fig. 1 , A, D) with veins yellowish brown.

Face ( Fig. 1 , C) with transclypeal suture obscure, laterofrontal sutures ( Fig. 1 , C) reaching the corresponding ocelli. Fore femur with anteromedial (AM1) row of seta present, intercalary (IC) row with about 11 fine and long setae. Hind femur ( Fig. 1 , F) with apical setal formula 2+2+1.

Male pygofer side ( Fig. 2 , I) with apical margin broad, with numerous long macrosetae near caudal margin and several bristles subapically arising from ventral margin. Valve rectangular. Subgenital plate ( Fig. 2 , J) with lateral margin sharply constricted near the middle, with microsetae arising from basal to middle region; apical process long, digitate, strongly curved dorsad, inner margin with one or two short macrosetae. Style ( Fig. 2 , K) with apical process long and bent, beak-like, apex sharply constricted and pointed, lateral lobe prominent. Connective ( Fig. 2 , L, M) Y-shaped; stem about as long as anterolateral arms, with a long process subapically on ventral surface; process directed ventrolaterad and tapered apically, not bifurcated. Aedeagus ( Fig. 2 , M, N) situated dorsad of connective and linked to it by membrane from apex of stem; aedeagal shaft curved dorsad in lateral view, ventroposterior margin with a pair of long basal broad processes; process strikingly extending beyond apex of shaft, terminating in a long slim process; lateral margin of process with six to seven uneven long and slender processes near the middle, inner margin with three to four short dentate processes; dorsoatrium developed, apically membranous bifurcation; gonopore ( Fig. 2 , M, N) situated upper near middle on posterior surface. Anal tube ( Fig. 2 , I) short and stout, strongly sclerotized laterally and dorsally.

Female: First valvulae ( Fig. 2 , O, P) with sculpturing pattern strigate dorsally, reaching dorsal margin; second valvulae ( Fig. 2 , Q, R) with serrate teeth on apical 1/3 or more.

Material examined. Holotype: ♁, Hainan Province, Diaoluo Mountains , 18°40.440′N, 109°52.600′E, 494 m, 10-VIII-2010, Coll. Zheng Guo ( NWAFU) . Paratypes: 1♁ 1♀, same data as the holotype .

Etymology. This new species epithet derives from the Latin combination “polyacantha” referring to the aedeagus with numerous similar spine-like processes.

Remarks. This species can be distinguished from other known species by the following unique characters: connective with a long process subapically on ventral surface,process not bifurcated;ventroposterior margin of aedeagal shaft with basal process extending well beyond apex of shaft, with several long or short similar spine-like processes.
