A. spinistyla; however, in caudal view (Fig. 627) ends of paired subterminal ventral processes are neither liraeform as in A. spinistyla nor straight as in A. paivana. The only unique character in the new species is almost equal length of the paired upper processes and the unpaired one and size and shape of lower lateral paired processes that are larger than in any of the two species and lyraeform in caudal view (Fig. 627). Aguriahana metallica Distant 1 M, Sikkim, Pelling, 2000 m, shrubs, 11. III. 1991,1. Dworakowska. Aguriahana paivana (Distant) 1 M, Sikkim, Rumtek, 1700 m, 5. Ill; 3 F, Pelling, 2000 m, 11. III. 1991, I. Dworakowska. Aguriahana picta Dwor. 1 M, Sikkim, Gangtok, N H-wy, 1800 m, 3. III. 1991,1. Dworakowska. Aguriahana pteridis sp. n. (Figs 635-643) Type material. - Holotype male: Sikkim, Rumtek, 1700 m, lamp domes, 1990, I. Dworakowska (in SMTD). - Paratypes: 1 F, same data as the holotype; 1 F, Rumtek, 1800 m, 6. III. 1991,1. Dworakowska (in SMTD). Body form as in A. aptera Dwor., colouration also similar but brighter and more contrastic. Vertex whitish or pale yellowish with distinct blackish line at its very anterior margin. Face whitish immediately below the blackish line, yellowish ventrad. Pronotum in dorsal view yellow to ochre-yellow with brownish-ochre lateral margins; on its side dark brown horizontal line being continuation of the dark line on vertex, ventrad of the line white. Scutum and scutellum yellowish. Basal triangles slightly tan. Fore wing bluish-white basally and basad of the light transverse fascia at the level of claval apex. Dark pattern shown in Fig. 642 blackish-brown, dark or light brown or tan. Female sternite 7 three-lobate at its caudal margin, yellowish-white with dark brown cephalic margin and a streak in the midline; sternite 6 dark brown except semicrescent-shape yellowishwhite area at its caudal margin; caudal margins of remaining sternites narrowly light. Thoracic sternites darkened. Legs light except sordid brown subbasal part of hind tibia, its dark brown terminal part and foot apicad from the end of 1st segment. Length M 3.25, F 3.10 and 3.20 mm. Comparison. Male genitalia similar to those of A. aptera but pygofer side (Figs 635, 636) and paramere (Figs 637, 638) more compact and penis different. Penis stem compressed laterally, its dorsal and ventral outline sinuate; dorsal process thin, narrow, sinuate, well separated from the stem and longer than in A. aptera; ventral process coalescent with the stem on most of its length; basal penis processes slim, strongly curved cephalad
