Empoasca (Matsumurasca) schima Thapa 4 M, Sikkim, Rumtek, 1700 m, lamp domes, 1990; 1 M, W Sikkim, Pelling, 2000 m, 11. III. 1991,1. Dworakowska. Empoasca (Matsumurasca) thapae sp. n. (Figs 152-164) Type material. - Holotype male, Sikkim, Rumtek, 1700 m, lamp domes, 1990, I. Dworakowska (in SMTD). - Paratype F, same data as the holotype (in SMTD). The biggest of all known Himalayan species of the subgenus. Olivaceous-green, apex of vertex and frontoclypeus ochre (in specimens from lamp domes). Whitish hypodermal pattern consists of patches at sides of vertex basally, in midline at anterior margin and behind eyes on pronotum, at anterior corners of scutum and in midline of scutellum in its anterior half. Length M and F 4.3 mm. Comparison. Male genitalia differ considerably from majority of species known in Matsumurasca but quite large dorsal apodeme of penis, sclerotized atrial processes and pigmented terminal part of paramere resemble E. (M.) aino (Mats.). In the present new species, however, there are two atrial processes at each side (Figs 152, 153) and paramere apex is uniquely shaped. The usual rised ledges or teeth arranged in a single file, allowing to distinguish dentifer, in E. (M.) thapae broke into irregular rows of separate pigmented teeth adorning club like end of paramere (Figs 157, 158). Ventral pygofer appendage broadened subapically, abrupt and deeply serrated at margin (Figs 161, 162). Anal tube appendage short, tubular, slightly broadened terminally and split there into small extensions (Figs 155, 156). Subgenital plate elongated apically (Fig. 164), setae of the basal group reduced in number and size (Fig. 163). Remark. The new species is named in honour of Mrs. Kalyani Thapa, the herbarium curator of the Forestry Department of the Government of Sikkim. Empoasca (Sabourasca) cornicula sp. n. (Figs 165, 166) Type material. - Holotype male: Sikkim, Singtam, 30. X. 1981, C. A. Viraktamath (in BMNH). Body form and colouration as in E. (S.) peculiaris (Ram. et Menon). Whitish hypodermal pattern distinct on vertex by eyes, in centre and behind eyes on anterior part of pronotum centrally, at anterior angles on scutum and in a form of three triangular patches at anterior margin of scutellum. Fore wing beige. Length M 3.6 mm. Comparison. The new species differs from E. (S.) peculiaris by penis structure. Dorsal extension on penis stem long and narrow in profile, both branches of the ventral apical penis processes of almost equal size (Figs 165, 166) and manubrial single process (not illustrated here) in the new species is shorter and more curved than in E.(S.) peculiaris. In the latter dorsal extension of the penis stem is lamellate and upper branch of apical penis process 4 to 5 times shorter than the lower one.
