[email protected] Introduction Some years ago, I studied the Orthoptera collected during the expeditions of Dr. Dierl, Dr. Forster, and Dr. Schacht to Nepal in 1964, 1967, and 1973 (Ingrisch 1990). The Tetrigidae had to be excluded as there were no reliable tools for Identification. The Tetriginae s. str. that represent the majority of the specimens at hand are not included in the works of Günther (1938a, b, 1939). Some authors even thought it impossible to identify Tetrigidae of several genera with accuracy (Kevan 1966, see also Blackith 1988). The taxonomic Situation of the Tetrigidae of the Oriental Region is still in a desolate State. Numerous of the classical taxa described by Bolivar (1887), Walker (1871), or Hancock (1904, 1907, 1909, 1910, 1912, 1913, 1915) have never been re-examined and from the descriptions alone it is offen impossible to be certain about their identify. A taxonomic revision of the Oriental Tetrigidae based on multivariate analysis of numerous characters that was projected by Blackith & Blackith (1987) did not appear. But meanwhile comprehensive works on the Tetrigidae of North India (Shishodia 1991) and China (Liang & Zheng 1998) are published, and there seems to be some agreement on the identify of the common species. The presenf paper gives a list of species of Tetrigidae collected during the Dierl-Expeditions to Nepal. Moreover, I use the opportunity to revise some of the Tetrigidae collected during an own excursion to Nepal (Ingrisch 1987). The Tetrigidae of the Dierl-Expeditions were collected at light and are all long-winged species. They are offen widespread in North India but several of the species were not yet reported from Nepal. Information on the collection sites can be found in Dierl (1966). The own collection contained two undescribed species. All specimens of the Dierl-Expeditions and the types of the new species are deposited in the Zoologische Staatssammlung München (ZSM); few other speciniens are in my own collection (CI). 147
