Silambarasan, 16 October 2019. Remarks. The specimen agrees with the descriptions provided by Kemp & Chopra (1921) and Ahyong (2016). Carinosquilla lirata closely resembles C. multicarinata, but several distinguishing features separate the two species. Notably, C. multicarinata possesses a pair of dark brown to black submedian patches on abdominal somite 5, which are absent in C. lirata. Additionally, the mandibular palp is present in C. multicarinata but absent in C. lirata. The shape of the prelateral lobe of the telson also differs, being sharp in C. multicarinata and blunt in C. lirata. Furthermore, the dactylus of the raptorial claw in C. lirata bears six teeth, whereas C. multicarinata has only five. Distribution. Vietnam, Thailand, Indonesia, Singapore to Madras, India (Ahyong 2016) this study). A new record for northeast coast of India.
