Four new species of the leafhopper genus Kapsa Dworakowska from China (Hemiptera, Cicadellidae, Typhlocybinae), with a key to Chinese species

Abstract In the present paper, four new species, Kapsa acuminata, Kapsa quadrispina, Kapsa puerensis and Kapsa yanheensis spp. n. from southwest China are described and illustrated, and a key to the species recorded from China is provided.


Remarks.
The new species is similar to K. biprocessa Song & Li (2008), but can be distinguished mainly by the aedeagus with pair of basal processes close to shaft; the more acute apex of shaft in ventral view with the gonopore longer (Figs 8, 9).
Etymology. The specific epithet is derived from the Latin word "acuminata" which refers to the acuminate apex of aedeagus in ventral view.
Abdominal apodemes slim, not exceeding 3rd sternite (Fig. 12). Male pygofer lobe with dorsal appendage slightly curved downward in lateral view (Fig. 13). Anal tube with processes very short, indistinct. Subgenital plate with three long macrosetae in oblique row and row of short stout setae along upper margin (Fig. 14). Style elongate, with apex slightly expanded; preapical lobe prominent (Fig. 15). Connective Yshaped with central lobe broad and arms short (Fig. 17). Aedeagus with pair of basal atrial processes, well separated from shaft, the latter with pair of short apical processes; gonopore moderately long; preatrium broad and dorsal apodeme short (Figs 15, 16).
Measurement. Body length male 2.8 mm.

Remarks.
The new species is similar to K. mingorensis (Ahmed, 1970) (see also ), but the aedeagus has a pair of basal processes, without apical vestiture (Figs 30, 31) and the preatrium is not expanded in lateral view (Fig. 30).
Etymology. The new species is named for its type locality: Yanhe.
