A new species of sergestid shrimp,acetes orientalis (Crustacea: Decapoda,Sergestidae) from Goa,Central West Coast of India

Acetes orientalis, a new species of sergestid shrimp belonging to the genus Acetes H. Milne-Edwards collected from the Mandovi estuary, Goa, Central West Coast of India has affinities to most of the Indo-Pacific species. The petasma of the male has resemblance in shape to. A. sibogae, A. vulgaris, A. sibogalis, A. australis, A. erythraeus and Acetes sp. and very much alike in structure to that of A. sibogae. The female genital area has a pair of protuberance as in A. vulgaris and A. indicus. These combinations in characters along with several other important features which justify the creation of this new species are discussed in comparison with those of the other Indo-Pacific species having closet affinities.
