Geizing, 1700 m, Alnus nepalensis, 12 III. All collected by me in 1991. (SMTD, NMNH, HNHM). Head ivory with some yellowish suffusions at base of vertex. Pronotum ivory except a broad medial streak and broad transverse fascia at hind margin that is golden-yellow or ochre-yellow, scutum and scutellum concolorous with the fasciae. Fore wing golden-yellow on clavus, cua and m cells, paler (almost white) costad. Veins at wing apex yellow. Smoked infuscation in the 1st, distal part of 2nd and in 3rd apical cells. Proximal part of 1st apical cell distinctly darker than distal. In some females almost whole vertex yellow. Length M 3.6-3.9, F 3.6-4.0 mm. Penis stem (Figs 234, 236) slim. Upper pygofer appendage almost straight, only slightly curved at apex (Fig. 243). Lower pygofer appendage nearly horizontal (Figs 235, 242). Upper part of paramere rounded subapically (Figs 237, 238). Comparison. The new species is distinguishable from A. (s. str.) indica Dwor. by its male genitalia. In A. indica penis stem is dilated basally, both pygofer appendages strongly arcuate and subapical curvature of paramere angulate. Alnetoidia (Alnella) defecta sp. n. (Figs 244-253) Type material. - Holotype male: Sikkim, Rumtek, 1700 m, lamp domes, 1990. Paratype 1 M, Labrang, 1800-2000 m, forest, 8. III. All collected by me and deposited in SMTD. The holotype lost its natural colouration during prolonged exposition to heat inside lamp dome, the paratype is without head. Probably colouration of upper side of head and thorax is yellow as in majority of species of the genus. Fore wing citrine, its base paler, the colour fades costad. Apical cells smoked: 1st and 4th totally and 2nd and 3rd in their apical 2/3 and 1/2 respectively. Length M (holotype) 3.80 mm, fore wing of paratype 3.4 mm. Terminal part of penis stem desclerotized, bent caudo-dorsad (Fig. 244) of the latero-ventral processes. Upper pygofer appendage arcuate, broadened subbasally (Figs 245, 249). Pygofer lobe bearing sclerotized conical extensions terminating internal ledge at ventro-caudal angle (Figs 245, 252). (This structure might correspond to the lower pygofer appendage of the nominate subgenus). Apical part of paramere (Figs 247, 248) broadened. Comparison. Male genitalia of the new species resemble A. (Alnella) sudzhuchenica Anufr. but the ventral prong on penis stem in A. defecta is divided into two processes while in the previous species it is single. Paramere of the new species is broadened apically while in A. sudzhuchenica it is tapering. Alnetoidia (Alnella) orientális Dwor. 17 M, 32 F, Sikkim, Rumtek, 1700 m, 5. Ill; 1 F, Labrang, 1800-2000 m, forest, 8. HI. 1991,1. Dworakowska.
