Liu, Yang, Qin, Dao-Zheng, Fletcher, Murray J. & Zhang, Ya-Lin, 2011, Review of Empoasca (Matsumurasca) Anufriev (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini), with description of three new species from China, Zootaxa 3003, pp. 22-42 : 27-29

Empoasca (Matsumurasca) dentalis Qin and Liu , sp. nov.

( Figs 42–50 , 141 , 150 , 159 , 168 )

Type material. Holotype, 3 ( NWAFU), China: Mt. Tianping, Sangzhi County, Hunan Prov., 14 Aug. 2001, 1250 m, coll. Qiang Sun.

Length. 3 4.6 mm.

Color. Vertex yellowish, with narrow creamy patch along coronal suture not reaching anterior margin, between eyes with small creamy streak sublaterally at each side of vertex. Eyes blackish brown, ocelli surrounded by creamy patch mesocaudad. Face yellowish green except base of frontoclypeal area and apical half of anteclypeus yellowish. Pronotum mostly yellowish, anterior margin and arcuate area behind eyes with irregular creamy patches; scutoscutellar sulcus brown. Forewing yellow green, forewing and hindwing subhyaline. Abdomen yellow. Legs yellow to sordid yellow.

Abdominal apodemes reaching segment VI ( Fig. 50 ). Male pygofer slightly elongated, with about 14 stout setae on each side; ventral pygofer appendage exceeding caudal margin of pygofer lobe, bent caudodorsad from basal 1/4 and broadened subapically, apical 1/5 apparently narrowed to pointed apex ( Figs 42, 43 ). Subgenital plate far exceeding pygofer side, broadened in apical 2/5, with 3 microsetae in basal group, about 24 marginal microsetae, 25–27 long lateral macrosetae and fine microsetae arranged in 2–3 irregular rows ( Fig. 45 ). Paramere with irregular rows of teeth apically preceeded by about 5–6 setae and few sensory pits ( Fig. 49 ). Aedeagal shaft Sshaped, in lateral view nearly twice as long as preatrium, broad in basal half and narrowing terminally, with pair of apical processes directed laterad in ventral aspect, gonopore apical ( Figs 46, 47 ). Connective lamellate, caudal margin incised medially ( Fig. 48 ). Anal tube process lamellate in side aspect, straight, almost same width through most of length and bearing 3 teeth at apex ( Fig. 44 ).

Female. Unknown.

Etymology. The new species name alludes to the dentate anal tube process.

Discussion. Empoasca (M.) dentalis sp. nov. is similar to E. (M.) biprocessa sp. nov., but differs from the latter by the anal tube process being straight and bearing apical teeth (sinuate and without teeth at apex in E. (M.) biprocessa ) and by the paramere apex with irregular rows of teeth (teeth arranged in a single file in E. (M.) biprocessa ).
