The present paper deals with a new thrips of Mt. Namjagbarwa region of Xizang (Ti-set), collected by Mountaineering and Scientific Expedition, Academia Sinica in 1982. The type specimens are kept in the Institute of Zoology, Academia Sinica.Taeniothrips glanduculus sp. nov. (figs. 1-4)Similar to Taeniothrips major Bagnall an Tacniothrips picipes (Zetterstedt). But many characteristics of the new species are often variable. Some characteristics of identical individuals consist with major and some consist with picipes often. It is difficult to distinguish the famale of the new species from that of major or picipes, whereas the male of the new species has very small sternal glands by which one can easily distinguished the new species from major and picipes. The sternal glands cover 32 μm and 0.16 of the sternal widths at most, and 15 and 0.08 at least; the average value, segment Ⅲ. 22 and 0.12, Ⅳ. 23 and 0.12. Ⅴ. 22 and 0.12, Ⅵ. 19 and 0.11, Ⅶ. 18 and 0.11.Holotype ((?)) and allotype ((?)) and paracypes (4(?), 17(?)) in the flowers of Heracleum candicans, Bomi Co., Xizang (Tibet), 3050M, 3-Ⅸ-1982; paratypes 4(?), 3(?) in the flowers of Polygonaceae, Getong, Bomi Co., Xizang, 3050M 3-Ⅸ-1982; paratypes 1(?), 2(?), in the flowers of Sambucus sp., Tiqin, Medog Co Xizang, 3400M, 7-Ⅸ-1982; by Han Yin-heng all. ACKNOWLEDGMENTI am grateful to Dr. Jenny Palmer of the British Museum (Natural History) London for here friendly letter and sending female and male specimens of Taeniothrips picipes to me. The -comments in her letter and specimens are of great usefulness to tny study.
