Material examined. FSI/VIZAG/CRUST. 229, 1 female (TL 98 mm), 17°43.1’N, 83°32.3’E, 53–54 m, coll. K. Silambarasan, 10 February 2019 .

Remarks. Oratosquillina perpensa is similar to O. inornata in most features but readily differentiated by the length and shape of the rostral plate. In O. perpensa , the rostral plate is relatively short and squarish, whereas, in O. inornata , it has a rectangular elongated form. Furthermore, a significant difference lies in the degree of surface pitting: it is finely and evenly distributed in O. inornata , while it is coarse in O. perpensa . Additionally, the shape of the anterior lobe of the lateral process of thoracic somite 6 differs: quadrate in O. inornata and triangular in O. perpensa ( Ahyong 2001) .

Distribution. India to Malaysia, Thailand, China, Taiwan, and Japan (Ahyong et al. 2008).
