Song, Yuehua & Li, Zizhong, 2012, Four new species of the leafhopper genus Kapsa Dworakowska from China (Hemiptera, Cicadellidae, Typhlocybinae), with a key to Chinese species, ZooKeys 212, pp. 25-33 : 27

Kapsa acuminata sp. n. Figures 1-10

Description.

Dorsum beige. Vertex with pair of milky yellow preapical spots; pronotum with anterior margin and median area ivory-white (Fig. 1). Forewing brownish yellow along inner and outer margin (Fig. 2).

Abdominal apodemes nearly reaching posterior margin of 4th sternite (Fig. 4).

Male pygofer with dorsal appendage bifurcate far from base (Fig. 5). Anal tube processes indistinct. Subgenital plate long, extended beyond pygofer apex, with three long macrosetae in oblique row (Fig. 6). Style elongate, preapical lobe distinct (Fig. 7). Connective Y-shaped with central lobe broad and arms short (Fig. 10). Aedeagal shaft laterally compressed distally, tapered to acute apex in ventral view (Fig. 9), with pair of processes at mid-length; gonopore long; preatrium long and dorsal apodeme short (Figs 8, 9).

Measurement.

Body length males 2.3~2.5 mm.

Type material.

Holotype, male, China: Guizhou Province, Mayanghe National Nature Reserve, 4 Oct. 2007, coll. Yue-hua Song. Paratypes: five males, same date as holotype.

Remarks.

The new species is similar to Kapsa 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.
