Typhlocyba tata sp. n. (Figs 833-844) Type material. - Holotype male: Sikkim, Rumtek, 1700 m, lamp domes, 1990, I. Dworakowska (in SMTD). - Paratypes: 2 M, same data as the holotype (in SMTD and NMNH). Vertex only slightly longer centrally than by the eyes. Head and pronotum whitish. An indistinct tan line on vertex, parallel but at some distance from the anterior margin. Scutum and scutellum yellow. The pattern transversely stripped in Fig. 838, orange. Anteclypeus of male not dilated. Fore wing whitish with bright orange patches and brownish to blackish-brown infuscations. Length M 2.75 mm. Comparison. Male genitalia resemble those of 77. dama sp. n. but in the new species there is distinct small lobe at caudo-ventral angle of pygofer and abruption at dorso-caudal angle (Fig. 841). Apex of subgenital plate produced in form of a stump bearing quite long rigid microsetae and the subapical extension is lobate, narrowing apically (Figs 833, 843). Apex of paramere very thin in the new species (Fig. 837), solid in T. dama. Penis stem in 77. tata is thick in lateral view, its lateral processes sinuate (Fig. 834), in T. dama it is thin apically, with almost straight processes. In posterior view the penis stem in the new species terminates on broad abrupt apex, its teeth situated on lateral cristae (Fig. 835), penis stem in 77. dama is narrow and tapering apicad and the teeth arise from the stem itself. Typhlocyba yacaba sp. n. (Figs 845-854) Type material. - Holotype male: Sikkim, Rumtek, 1700 m, lamp domes, 1990, I. Dworakowska (in SMTD). Vertex strongly produced anteriorly. Ivory, with an orange mark at the tip, two blackish-brown dashes anteriorly and a reddish-orange patches at sides (Fig. 851). The only preserved sides of pronotum as well as scutum and scutellum ivory with an orange pattern; tip of scutellum blackish-brown. Face whitish, with a short orange-red dash in midline apically, brown patch on upper part of anteclypeus and another U-shape on its ventral extreme; a small brown patch at eye above base of antenna and a dark brown crescent-shape patch on inner part of gena at the suture of frontoclypeus below base of antenna. Thorax beneath whitish except darkened centre of mesosternum. Legs yellowish-white, bases of large, partly infuscated setae, dark brown; brownish-black patch at apex of hind tibia. Fore wing damaged very much, its apical part missing, approximated in Fig. 853. Colour whitish, pattern transversely stripped in Fig. 853, orange; that dotted or obliquely dashed beige to brownish. From the reconstruction it is presumed that apical cells are shorter than in any other Asiatic species of the genus. Deduced total length of the single male 2.43 mm. [0.47 mm to the end of pronotum and 1.96 mm approximated length of the fore wing]. Comparison. Male genitalia resemble T. aptera Dwor. the most, especially by the ventral position of rigid microsetae of pygofer and its pigmented and sculptured extension in the region of dorso-caudal angle (Figs 845, 846). Caudal part of paramere (Figs 847, 848) longer than in any species of the T. quercus (L.) group and A. aptera but shorter than in 77. arborea Dwor. group. Connective lamellate, with solid numerous scleroti-
