Saini New records of Nesoselandria Rohwer from India (Hymenoptera: Symphyta, Tenthredinidae, Selandriinae) — Four species of the genus Nesoselandria Rohwer are added to the Indian sawfly fauna. Of which three are new to science, while the fourth one is new to the Indian subcontinent. Described as new are: N. emarginata, N. infuscata and N. elost, whereas, N. leucopoda Rohwer, recorded for the first time from this subcontinent, is redescribed along with the construction of a key to the Indian species of this genus. INTRODUCTION Rohwer (1910) erected the genus Nesoselandria taking Paraselandria imitatrix Ashmead as its type species from the Philippines. Again, Rohwer (1915) added a new species to this genus from Calcutta, India. Malaise (1944) shifted Aneugmenus annandalei Rohwer and Neobusarbia flavipes Takeuchi to this genus. Benson (1939) erected a new genus Melisandra taking Selandria morio (Fabricius) as its type species from Holarctic region but Smith (1969) synonymized it under Nesoselandria. Malaise (1944) made two new additions i. e. Nesoselandria sulciceps from Dehradun and Nesoselandria turneri from Shillong. Some of the other important works, concerning this genus from the Oriental region include those of Enslin (1912), Rohwer (1916), Takeuchi (1928) and Forsius (1929-1933). Prior to work, this genus was represented by 22 species from the Oriental region. Of which only four species were on record from the Indian subcontinent. This genus is now represented by 8 species in India, out of which one (N. leucopoda Rohwer) is recorded for the first time, while three (N. emarginata, N. infuscata, N. elost), are added as new to science. The present text deals with the systematic descriptions and illustrations of these four species and also with the construction of a key to the Indian species of this genus. The terminology used in the text is after Ross ( 1937, 1945) and Malaise (1945). This genus is widely distributed throughout the Holarctic and Oriental regions. The type materials of the new species are housed at the Division of Entomology, Pusa National Collections, Indian Agricultural Research Institute, New Delhi, India, while either a female or a male (Paratype: whatever is available) of each species are deposited in the Department of Zoology, Hungarian Natural History Museum, Budapest (henceforth HNHM).
