Lophosquilla tiwarii Blumstein, 1974 (Fig. 3A) Squilla costata Kemp, 1913: 84. Lophosquilla tiwarii Blumstein, 1974: 123–124, fig. 8.— Ahyong 2001: 274–278, fig. 135.— Trivedi et al. 2020: 228. Toshimitsu tiwarii. — Manning 1995: 235–236, fig. 142.— Ahyong & Naiyanetr 2002: 302–303. Material examined. FSI/VIZAG/CRUST: 218, 1 male (TL 90 mm), 20°01.6’N, 86°47.2’E, 44–45 m, coll. K. Silambarasan, 12 March 2020. Remarks. The present specimen of L. tiwarii, the largest so far known, closely agrees with the description provided by Moosa & Cleva (1984) and Ahyong (2001). The rostral plate is elongated and the raptorial claw dactylus bears 6 teeth, consistent with previous descriptions, although the telson denticulation exhibits a distinct variation. Previous accounts describe multiple submedian denticles on each side of the median fissure, but our specimen processes only a single submedian denticle per side. The abdominal spination of the present specimen is follows: submedian 6, intermediate 5–6, lateral 3–6, marginal 1–5. Distribution. Myanmar, Thailand, Indonesia, the Philippines and Vietnam (Moosa & Cleva 1986; Ahyong 2001, 2012); a new record for the northeast coast of India.
