Shrimps of the genusAcetes H. Milne Edwards (Crustacea, Decapoda, Sergestidae) from the estuarine system of river Krishna
Four species ofAcetes, viz.A. indicus, A. erythraeus, A. japonicus andA. sibogae are reported from the estuarine system of river Krishna on the east coast of India. Their systematics is discussed in the light of intra-specific variations. The synonymy ofA. cochinensis withA. japonicus is corroborated.A. australis, A. sibogalis andA. orientalis are all shown to be junior synonyms ofA. sibogae. A key to the identification of species ofAcetes known from India is given.
