Type locality. Bhandarkhal, Kathmandu, Nepal. (Forest Research Institute, Dehra Dun, India). Distribution. Nepal, India (Sikkim).

Empoasca (Matsumurasca) spinalis Qin and Liu , sp. nov. ( Figs 119–127 , 146 , 155 , 164 , 173 )

Type material. Holotype, 3 ( NWAFU), China: Mt. Jigong, Henan Prov., 11 Jul. 1997, coll. Jian Hu. Length. 3 3.9 mm.

Color. Vertex cyan, with longitudinal creamy patch along coronal suture not reaching anterior margin, between eyes with creamy streak sublaterally at each side of vertex. Eyes brown, ocelli surrounded by creamy patch mesocaudad. Frontoclypeal area yellowish green, centrally with longitudinal creamy patch in basal half; anteclypeus and genae green. Pronotum bearing irregular creamy patches at anterior margin and arcuate area behind eyes; scutellum with quadrate creamy patch antero-mesally and apicad of scutoscutellar sulcus with an irregular creamy patch. Forewing yellowish green, fore- and hindwing subhyaline. Legs yellowish except tarsi and apical half of hind tibia cyan.

Abdominal apodemes parallel-sided, rounded apically, surpassing midlength of segment V ( Fig. 127 ). Male pygofer slightly elongated and rounded apically, with about 11 stout setae on each side; ventral pygofer appendage nearly straight, directed dorsocaudad and exceeding caudal margin of pygofer lobe, tapering in apical 1/4 to pointed apex ( Figs 119, 120 ). Subgenital plate far exceeding pygofer, prominently broadened at base and triangularly protruded basolaterad, apical 1/4 curved dorsocaudad, basal group with 4 long, thick setae, about 23 short marginal microsetae, 22–23 long lateral macrosetae and fine microsetae arranged in 2 irregular rows ( Fig. 122 ). Paramere with 5 apical teeth and 2 relatively big teeth subapically preceeded by about 4–5 setae and few sensory pits ( Fig. 126 ). Aedeagal shaft straight in lateral view, nearly as long as preatrium, broad basally and narrowing terminally, with short spinose process baso-ventrally and 2 teeth on dorsal side, dorsal surface in basal 1/3 and ventral surface mostly concave, dorsal apodeme of aedeagus short, in ventral aspect expanded laterad, gonopore ventrad near apex ( Figs 123, 124 ). Connective lamellate, caudal margin incised medially ( Fig. 125 ). Anal tube process curved anteroventrad and gradually tapered to pointed apex ( Fig. 121 ).

Female. Unknown.

Etymology. The new species name alludes to the spinose process on the aedeagal shaft.

Discussion. Empoasca (M.) spinalis sp. nov. is similar to E. (M.) onukii Matsuda, 1952 , but differs from the latter by the ventral pygofer appendage being straight (sinuate in E. (M.) onukii ), and by the aedeagal shaft armed with a short spinose process baso-ventrally and 2 dorsal teeth (spinose process and teeth absent in E. (M.) onukii ).
