Material examined. FSI/VIZAG/CRUST. 225, 3 females (TL 99–121 mm), 21°00.4’N, 87°33.0’E, 32–33 m, coll. K. Silambarasan, 19 March 2020 .

Remarks. Our specimen closely aligns with the description provided by Manning (1978c). While this species closely resembles Oratosquillina nordica Ahyong & Chan, 2008 , it is clearly distinguishable by the structure of the anterior lobe on the lateral process of the sixth thoracic somite. In O. quinquedentata , the anterior lobe is approximately equal in length and width, with its width being about half that of the posterior lobe. It has a broad, trapezoidal shape, unlike the anterior lobe of O. nordica , which is more slender, finger-like, and nearly twice as long as its width (Ahyong & Chan 2008).

Distribution. Arafura sea, Australia, and India ( Ahyong 2001; Trivedi et al. 2020).
