plate lamellate, broad, narrowing near its very end (Fig. 950). Penis stem tubular, narrowing apicad, provided with minute lateral extensions at apex (Figs 946, 947). Basal abdominal apodemes of male reaching half of segment 5, parallel-sided, rounded apically (Fig. 953). Comparison Zyginella nadobna sp. n. seems to be the closest related to Z. angusta sp. n. The important similarity includes pygofer and subgenital plate structure and setosity, distribution of setae on paramere (Figs 935 and 950) and penis structure. At the same time distinct differences in colouration and details of penises (as described above) allow to separate them. ACKNOWLEDGEMENTS At this opportunity I like to thank the numerous persons of the Forest Department of the Government of Sikkim for provided help, in particular Mr N. C. Shenga, Chief Conservator of Forests-I, Mr P. K. Basnett, Chief Conservator of Forests-II and Mrs Kalyani Thapa, Herbarium Curator. Some of the local plants have been identified by Mr N. R. Mandai of the Botanical Survey of India in Gangtok and others by Dr S. Chakrabarti of the University of Kalyani, India. Access to the facilities of Spencer Entomological Museum, through the courtesy of Dr G. G. E. Scudder enabled me to prepare the above faunistic review. REFERENCES Datta, B.
