First record of Jonas kalpakkamensis Barathkumar, Das & Satpathy, 2016 (Decapoda: Brachyura) and Ozius tuberculosus H. Milne Edwards, 1834 from the northern part of the east coast of India

Abstract

Two brachyuran crabs, Jonas kalpakkamensis Barathkumar, Das & Satpathy, 2016 (Decapoda: Brachyura), and Ozius tuberculosus H. Milne Edwards, 1834, were documented for the first time from the Northern part of the east coast of India. The former species was collected from Chandanipal fish landing centre, Dhamara, and the latter was collected from Aryapalli fish landing centre, Chatrapur, Odisha. The species J. kalpakkamensis differs from its congeners by the distribution of tubercles on the carapace, spines on the fourth leg and the curvature of G2. Ozius tuberculosus differs from its congeners by the presence of tubercles on its dorsal side and the absence of spot marks on the ventral side. The documentation of these two species will be a valuable addition to the carcinological fauna of Odisha, India.
