Key words: Conidae, Range extension, Distribution Kerala, Redlist INTRODUCTION Cone snails are the members of a highly diverse marine gastropod family Conidae that are renowned and appreciated for their fast diversification and species richness, exquisite splendour of shells and sophisticated venoms that are potentially dangerous to humans on one hand and beneficial on other hand by virtue of the forms of drugs derived from it (Puillandre et al., 2014). Though cone shells occur throughout the tropical and sub-tropical oceans, they are most numerous within the Indo-West Pacific region; recorded diversity includes 316 species of cone shells from the Indo-Pacific region (Filmer, 2001; Rockel et al., 1995), 73 species from Indian coastal waters (Apte, 2014) and 53 species from the Andaman and Nicobar islands (Apte, 1998, 2012, 2014; Hylleberg and Kilburn, 2002; Rao, 2003; Venkataraman et al., 2004, 2012). Benjamin et al. (2009) recorded sixty species of cone shells from the Tamil Nadu, southeast coastal region of India. Of late 17 species of cone shells were recently recorded from Kerala coast by Franklin and Laladhas (2014) and 10 species by Sary et al., (2014). Shell collectors and commercial traders have established good trade made of cone shells in global market (Rice, 2007). Conus vicweei is a species with good market prize value globally and has been reported from Indonesia, Myanmar, Thailand and Malaysia (Rockel et al., 1995; Kohn, 2013). In the present paper we record the presence of this species from Lakshadweep Sea, southwestern India. MATERIALS AND METHODS The specimen was collected from the commercial trawlers operating off Kerala coast, India at a depth of about 150-200 m. Identification of specimen was done based on key taxonomic features provided in Old (1973), Rockel et al. (1995) and Robin (2008) and measurements were done using digital Vernier Calliper (Aerospace, China). Voucher specimen is deposited in the museum collections of the Department of Aquatic Biology and Fisheries, University of Kerala (DABF/UOK/GAS- 31).
