Longhorned beetles ( Coleoptera : Cerambycidae ) from Chhattisgarh , India

Acknowledgements: Authors are grateful to Dr. K. Venkataraman, Director, Zoological Survey of India, for providing necessary facilities and encouragements. Thanks are also due to Chhattisgarh Forest Department for providing necessary permissions and support to carry out the present work The pioneering taxonomic and biological investigations on cerambycid beetles in India were initiated in the 20th century. Gahan (1906) was the first to compile and describe the known cerambycid beetles, excluding Lamiinae, from the Indian region in the ‘Fauna of British India’. After that, extensive work on the diversity and distribution of cerambycids from India is particularly lacking. Some scattered publications on longhorned beetles of India by White (1853), Sengupta & Sengupta (1981), Khan & Maiti (1983), Basak & Biswas (1985, 1993), Biswas & Basak (1992), Raychaudhuri & Saha (2000), Mukhopadhyay & Biswas (2000, 2002) and Mukhopadhyay & Halder (2003, 2004) are available. Recently, Sen & Ghate (2006) and Ghate (2012) also published some information on cerambycid fauna of Maharashtra, India. This report is the first report on the family cerambycidae from the state of Chhattisgarh after its separation from the erstwhile Madhya Pradesh State. The present study accounts for 10 species of Cerambycid beetles belonging to eight genera and six tribes under two subfamilies and constitute a first record from Chhattisgarh State. Materials and Methods: Study period: The specimens were collected from different parts of Chhattisgarh during the period July 2011 to December 2012. Collections were mostly made during the monsoon (July to September) and post monsoon (October and November) seasons. Study area: Chhattisgarh is a newly carved out state from Madhya Pradesh in 2001. The state extends between 17046’–2408’N and 80015’–84024’E in the central Indian landscape having a total area of 1,35,194km2. Nearly 44% of the area is covered by forests but a major part (35,736.239km2) is outside protected areas. Biogeographically, the state belongs to the Deccan Plateau and includes provinces, 6D-Chota Nagpur Plateau, 6C-Eastern Highland and 6E-Central Highland (Rodgers et al. 2002). Methods: Cerambycid beetles are best collected at night with the help of a light trap. Mercury bulbs (160 Watt) were used to attract insects on a white sheet of cloth measuring approximately 2x2 m. The coordinates of the collection sites were recorded using GPS (Garmin Oregon 550) which were further used in preparing maps of the survey sites in DIVA-GIS (Fig. 1). Specimens were studied under Leica EZ4 HD binocular microscope for identification. The specimens were identified with the help of available published literature on Cerambycidae from India and confirmed by comparing the reference collection of National Zoological Collection at Zoological Survey of India, Kolkata. The studied material is deposited in the National Zoological Collection, Zoological Survey of India, Kolkata. ISSN Online 0974–7907 Print 0974–7893

Discussion: The present report is the first comprehensive account on the cerambycid beetles from Chhattisgarh.The state's forest cover is almost 60% which indicates very good timber production.It is imperative to study the longhorned beetles being destructive to forests.A thorough survey in different areas of the state can reveal more than twice the number of species reported in this paper.
