Empoasca (Distantasca) latibasis Zhang & Liu View in CoL sp. n.

( Figs. 128–139 View FIGURES 128 – 139 , 170 View FIGURES 158 – 170 , 183 View FIGURES 171 – 183 , 196 View FIGURES 184 – 196 , 209 View FIGURES 197 – 209 )

Type material. Holotype: 3 ( NWAFU), Munai, Yunnan Prov., China, 2 Dec. 2004, 1100m, coll. Dworakowska. Paratypes: 1 3 1 Ƥ, same data as holotype; 1 3, Munai, Yunnan Prov., China, 2 Dec. 2004, 1100m, coll. Qin Daozheng.

Length. Male: 3.2–3.4 mm, female: 3.3mm.

Ground colour of body green-yellowish. Crown with pale green patch on each side of coronal suture, in some specimens with narrow brown line along medial suture. Eyes black-brown. Pronotum broad, with irregular patches of cream-yellowish on anterior margin. Forewing semitransparent with light yellow-greenish tint, hind wing transparent. Abdomen yellow. Legs light yellow to gold.

Abdominal apodemes long, reaching middle of 5th segment, subparallel-sided to rounded apices, some specimens (including holotype) with small triangular projection extended ventrad from 4th segment margin on either side of midline, apodeme with lightly sclerotized spot just above each projection ( Fig. 134 View FIGURES 128 – 139 ). Male pygofer slightly narrowing caudad, ornamented with 11–14 rigid setae on each side of pygofer lobe ( Fig. 128 View FIGURES 128 – 139 ); ventral pygofer appendage slightly curved dorsocaudad, exceeding caudal margin of lobe ( Fig. 129 View FIGURES 128 – 139 ). Anal appendage stout, strongly constricted and tapered to acute apex, with big tooth subapically ( Fig. 137 View FIGURES 128 – 139 ), in one specimen anal appendage slightly different ( Fig. 136 View FIGURES 128 – 139 ). Subgenital plate sinuate, with numerous macrosetae and fine setae in somewhat irregular arrangement; inner margin with 22–29 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 ( Fig. 139 View FIGURES 128 – 139 ). Paramere with 7 teeth on dentifer, 4–8 setae subapically ( Fig. 138 View FIGURES 128 – 139 ). In posteroventral view, aedeagus relatively thin, expanding gradually to atrium, shaft thin and subparallel-sided, apex with lateral processes directed caudoventrad in profile, gonopore subterminal on ventral surface. Connective broad, with caudal margin deeply emarginate medially ( Fig. 135 View FIGURES 128 – 139 ).

Etymology. The species name is derived from the Latin words “latus” or broad and the Greek “basis” or foundation and refers to the very strong base of the anal appendage.

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

Remarks. The new species is similar to Empoasca (Distantasca) paraterminalis Qin & Zhang, 2007 , but differs in the length of the pygofer appendage which is shorter than the style; in the aedeagus, with lateral processes apically directed caudoventrad in profile, and in not having two pairs of subbasal appendages.
