An Updated List of Cerambycid Beetles (Coleoptera: Cerambycidae) of Assam, India

The study on long horned beetles from the northeast Indian state Assam is very poor with many species awaiting discovery, study and description. Among the seven sister states, cerambycid fauna of Arunachal Pradesh, Tripura, Meghalaya, Manipur, Mizoram, Nagaland are mostly worked out by the Zoological Survey of India and some other universities and institutions. But nothing has been published on the Cerambycidae fauna of Assam in particular (after separation from other states of north-east India).Therefore, an attempt has been made to prepare a consolidated and updated list of cerambycid beetles reported from Assam state after compilation of the published works on cerambycidae of India. The voluminous works on the cerambycid fauna in north east India were mostly done by Gahan (1894, 1906) and Breuning (1936, 1938a, 1938b, 1954, 1958, 1965). Afterwards, Kapur (1954), Basak and Biswas (1985), Mukhopadhyay and Biswas (2000a, 2000b), Ray Chaudhuri and Saha (2000), Mukhopadhyay and Halder (2003, 2004), Mukhopadhyay (2011), Saha et al. (2013), Mitra and Majumder (2014), Mitra et al. (2016a, 2016b,2016c) have reported some more species from Assam in their published works. Family Cerambycidae includes more than 35,000 species under 4,000 genera in 11 subfamilies in the world, therefore this beetle family is considered as one of important coleopteran family (Agarwala & Bhattacharjee, 2012). This communication is the first updated consolidated list of cerambycid beetles from the state of Assam (after complete separation from other states of NE India in 1987) which includes 95 species under 64 genera of 32 tribes belonging to 3 subfamilies along with their distribution.

Insect Faunal Diversity of the Sunderban Biosphere Reserve, West Bengal, India

Present paper confirms the report of 591 species, under 404 genera of 100 families belonging to 13 orders of insects from the Indian parts of Sunderbans. In terms of species richness, the order Lepidoptera is the most speciose (163 species), followed by Diptera (133 species), Hyemnoptera (96 species), Coleoptera (81 species), Orthoptera (19 species), Dermaptera (8 species), Isoptera (7 species), Neuroptera (6 species), Thysanoptera (2species), Blattodea (2species) and Phthiraptera (2 species).
