    Abstract

    The deep water penaeoid shrimp is an important commercial crustacean resource along the Indian coast. The molecular and morphological information of this group from the Indian coast is scarcely known. In this study, we investigated the identification and phylogenetic relationships of the deep water penaeoid shrimps using three mitochondrial (cytochrome oxidase subunit I (COI), cytochrome b, 16S rRNA) genes, which were compared with 54 morphological characters and further used to evaluate character evolution. Our study revealed remarkable molecular divergence (3.3–33.0%) in nine species from three genera of Solenoceridae, four species from three genera of Penaeidae and one species from Aristeidae using COI. Phylogenetic analysis using maximumlikelihood and Bayesian approaches revealed that all species from these families are monophyletic. The present analysis revealed the existence of subgroups in the genus Solenocera suggesting the slow reduction of postrostral carina which corresponds to the increase in distributional depth during the evolutionary process which further indicates the origin of the genus in the continental shelf and extending up to the continental slope. In addition, we generated the DNA barcode database involving these species which can help further to investigate the detailed evolution and biogeography of these valuable crustacean resources.
