Wang, Ran, Zhang, Yalin & Cao, Yanghui, 2025, Review of the genus Ishiharella Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae), with description of two new species, Zootaxa 5604 (2), pp. 176-184 : 181-182

Ishiharella wuxiensis sp. nov.

( Figs 5–8 , 11, 16 , 29–36 )

Type material: Holotype. ♂ ( NWAFU), China, Chongqing, Wuxi County, 17-VIII-2023, Qingquan Xue.

Paratypes. 3 ♂♂ ( NWAFU), same data as holotype .

Description. Length: male 3.8–4.0 mm.

Crown yellowish orange. Vertex with the central subcircular black patch at base blackish, submedially with a small brownish spot on each side. Eyes dark, ocelli white. Face yellow, except anteclypeus black apically. Pronotum laterally with sinuate transverse depressions black brown on each side. Scutellum yellow, apex slightly black, scutoscutellar sulcus brownish. Abdomen dark brown infuscated in dorsally. Forewing brown, hind wing hyaline. Legs yellowish except claws black ( Figs 5–8 ).

Male 2S abdominal apodemes reaching the posterior margin of segment IIV, basal apodemes broad, apically narrowed ( Fig. 29 ). Male pygofer brown, elongated in lateral view, narrowed in apical 1/5, terminally with 10 rigid microsetae on each side of lobe, with ca. 8 filamentous setae on outer face near dorsal margin, caudoventral protrusion of pygofer short, in lateral view not surpassing the end of pygofer side and incised subbasally ( Figs 11, 16 , 30 ). Subgenital plate surpassing pygofer lobe, fused almost to apex; ca. 40 microsetae uniseriate in most part; arising near middle of plate with 6–7 feeble macrosetae in alignment, reaching apex ( Figs 11, 16 , 30–31 ). Aedeagal shaft slight long, broad, ovoid, width of base nearly equal to width subapically, gonopore terminal, basoventral protrusion of aedeagus slender, sinuate, slightly shorter than shaft, in ventral aspect bifurcated at the middle, parallel extended with pointed apex, without dorsoatrium, ( Figs 11, 16 , 32–33 ). Connective lamellate caudally and crimped basally, caudal margin concave medially ( Figs 11, 16 , 34 ). Paramere surpassing pygofer in lateral view, almost the same length with subgenital, curved medially and bifurcated near apically, bearing a rigid tooth basad of bifurcation ( Figs 11, 16 , 35 ). Anal tube appendage developed, skeletonized, curved toward apex ( Figs 11, 16 , 36 ).

Notes. This new species is similar to I. iochoui Dworakowska and I. falcata Yu, Yang & Dietrich in having the aedeagal process branched, but differs in the structure of the paramere and pygofer. It can be distinguished from I. iochoui by the subgenital plate fused almost to apex ( Fig. 31 ) and anal tube appendage developed ( Fig. 36 ). It also differs from I. falcata by the paramere branched near apically and the position, structure of the branching of aedeagal basoventral protrusion ( Figs 33, 35 ).

Etymology. The new species is named after its type locality: Wuxi County, Chongqing Municipality.

Distribution. China (Chongqing).
