Empoasca (Distantasca) tuberculata Zhang & Liu sp. n.

(Figs. 118–127, 169, 182, 195, 208)

Type material. Holotype: 3 (NWAFU), Mengyuan, Yunnan Prov., China, 11 Nov. 1999, coll. Dworakowska. Paratypes, 1 3, same data as holotype; 1 3, Mengyuan, Yunnan Prov., China, 11 Nov. 1999, coll. Qin Daozheng.

Length. Male: 3.2–3.4 mm.

Ground colour of body yellowish-green. Crown with light yellow or cream markings on each side of coronal suture. Eyes blackish-brown. Pronotum with irregular patches on anterior margin of pronotum and behind eyes. Forewing and hind wing semitransparent. Abdomen yellow. Legs light yellow to gold.

Abdominal apodemes subparallel-sided, reaching base of 5th segment (Fig. 123). Male pygofer slightly narrowing caudad, ornamented with 12–16 stout setae on each side of pygofer lobe; ventral pygofer appendage slightly curved dorsocaudad, exceeding caudal margin of lobe (Fig. 118). Anal appendage long, broad at base, tapering to pointed apex with some irregular teeth (Fig. 125). Subgenital plate sinuate, with numerous macrosetae and fine setae scattered irregularly; inner margin with 22–27 short microsetae on apical half and two bands of long, hair-like setae on lateral surface-one near mid-length of plate and one just before apex, often separated by few thin but short setae (Fig. 127). Paramere with 8 teeth on dentifer, 4–6 setae subapically (Fig. 126). Shaft as long as preatrium, broad at base in lateral view, gradually tapering and curved at basal 2/5, shaft subbasally with pair of processes directed caudodorsad; each process with teeth-like or papillose tubercles arranged irregularly at apex, gonopore subterminal on ventral side (Figs. 121, 122). Connective broad, with posterior margin deeply emarginate medially (Fig. 124).

Etymology. The species name is derived from the Latin word “ tuberculata ”, which refers to the tooth-like or papillose tubercles on the apices of the long processes of the aedeagus.

Distribution. Known only from the type locality in Yunnan Province (SW China).

Remarks. This new species is similar to Empoasca (Distantasca) serratipenis Qin & Zhang, 2007, but can be distinguished from the latter by the following characters: aedeagal shaft fairly long, with pair of distally serrate processes arising near base.
