Anadarinae, Anadara, East Coast of India, First report, Mosambicarca, Tegillarca


Two species of ark shells i.e., Anadara consociata (E.A. Smith, 1885) and Anadara troscheli (Dunker, 1882) reported for the first time from Indian waters. These two species were identified based on the collections from different surveys along east coast of India and specimens of National Zoological Collections of Marine Aquarium and Regional Centre, Zoological Survey of India, Digha. Overall eleven species of subfamily Anadarinae of family Arcidae are presented in the current paper. The taxonomic compilation of the eleven species is done with specimens available in the study localities. A key of the eleven species is presented here for future references. These two species are overlooked with related species during the earlier studies from this region.
