Yang, Xiao, Luo, Guimei & Song, Yue-Hua, 2022, Two new species of the genus Kapsa Dworakowska from the karst area of Southwest China (Hemiptera: Cicadellidae: Typhlocybinae), Zootaxa 5174 (2), pp. 195-200 : 196-198

Kapsa (Kapsa) huajiangensis sp. nov.

Description. Head brownish, as wide as pronotum. Face light yellow-brownish, relatively short, with anteclypeus pentagonal ( Figs 1, 3, 4 ). Pronotum white yellow. Scutellum yellowish with white spots. Forewing and hind wing almost transparent ( Figs 1, 3 ).

Male abdominal apodemes extended to hind margin of 4th sternite ( Fig. 13 ).

Male genitalia. Male pygofer without macrosetae and with dorsal appendage long, not bifurcate at apex. Ventro-caudal margin sharp (Fig. 6,11). Subgenital plate broadened subbasally, with two short macrosetae on lateral surface, numerous peg-like setae along dorsal margin from subbase to apical part ( Fig. 7 ). Style long, with apex foot-like, with sculpture; preapical lobe prominent ( Fig. 10 ). Aedeagus with paired processes arising from base of shaft; preatrium much longer than shaft, forming obtuse angle with shaft ventrally in lateral view; dorsal apodeme broadened, triangular in lateral view; shaft almost straight, apex divergent and tapered in ventral view ( Figs 8, 9 ). Connective with central lobe broad and lateral arms robust, stem almost absent ( Fig 12 ).

Specimen examined. Holotype: ♂, CHINA, Guizhou Prov., Huajiang , 24 VI 2020, coll. Jia Jiang. Paratypes: 3♀, same data as holotype .

Measurement. Body length ♂ 1.6 mm; ♀ 1.8~2.0 mm.

Remarks. This species is similar to Kapsa (K.) acuminata Song & Li (2012) , but differs in having the aedeagus with processes as long as the shaft; the aedeagal shaft narrow, figure-like in lateral view ( Fig. 8 ), the aedeagal preatrium much longer than shaft ( Figs. 8, 9 ) and the pygofer dorsal appendage not bifurcate at apex ( Figs 6, 11 ).

Etymology. The new species is named for its type locality: Huajiang.
