Saini, Muzamil Ahmad and Vikram S. Rathor Department of Zoology & environmental Sciences, Punjabi University, Patiala-147002, India. Email: [email protected] Abstract Five new species of the genus Tenthredo Linnaeus, 1758 are described and illustrated from the Indian Himalayas. Which includes Tenthredo bandata sp.nov., T.clavata sp.nov., T. fuscata sp.nov., T. kalamunitopensis sp.nov. & T. nigrofuscata sp.nov. While compiling the Indian Sawflies Biodiversity (Vol. I), Saini (2007) included these new species only in the key whereas the detailed descriptions and diagnostic combinations of these new species were not provided in that compilation.With the addition of these five new records, the genus Tenthredo is now represented by 196 species from India. The genitalia are illustrated, and all these species are distinguished from related species. The population variation, if any, has also been discussed. Keywords : Hymenoptera, Symphyta, Tenthredinidae, Tenthredo Linnaeus, Himalayas, India. Introduction Mocsary, 1883 (1 sp.); Jakowlew, 1891 (3 sps.); Though the taxanomic work on Indian Konow, 1898, 1900, 1903, 1906, 1907, 1908 (30 Tenthredo is quite scattered, still Malaise’s (1945) sps.); Matsumara, 1912 (1 sp.); Rohwer, 1915, paper is such an exhaustive study that, in addition 1916,1921 (4 sps.); Forsius, 1931, 1935 (2 sps.); to compiling almost all the earlier works for south- Benson, 1941 (1 sp.); Muche, 1982, 1983, 1986 east Asia, adds 18 new species of this genus to (4 sps.); Shinohara 1988, 1998 (3 sps.); Harris the Indian fauna. The only additional Works since 2004 (4 sps.). Malaise (1945) are that by Muche 1982, At present Tenthredo Linnaeus is a complex 1983,1986; Shinohora 1988, 1998 & Haris 2004 genus with almost 979 species on record (Taeger who made an addition of 11 new species to the et al. 2011). Out of these 979 species 439 species earlier census of Indian Tenthredo and brought have been assigned to its 19 subgenera which the total number of described species from this include subgenus Tentredo (100), Adungia (4), country to 90. It was late in the 20th century, Casipteryx (3), Cephaledo (16), Dorhetteryx (26), that Saini and his co-workers (1985-2006) made Elinopsis (1), Elinora (54), Endotethryx (3), some major contributions to this genus and to Eurogaster (25), Maculedo (7), Metallopeus (17), this date the picture is completely changed with Olivacedo (21), Paratenthredo (6), Peus (4), 191 valid species documented from this region. Propodea (2), Temuledo (28), Tenthredella (93), This includes 91 new species recorded by Saini Tenthredina (18) & Zunuledo (11). & his co-workers alone, 33 species as the first record. Other important works prior to Malaise Material and Methods 1945 includes Radoszkowsky, 1871 (2 sps.); Material for the present study was collected Cameron, 1876, 1877, 1899, 1902 (13 sps.); during different field trips to the high altitude Smith, 1878 (5 sps.); Kirby, 1882 (2 sps.); regions of Uttarakhand.
