Harpiosquilla annandalei

Harpiosquilla annandalei (Kemp, 1911) (Fig. 2D) Squilla annandalei Kemp, 1911: 99.— Kemp 1913: 92, pl. 7 fig. 78–79. Harpiosquilla annandalei.— Ahyong 2001: 257, fig. 125.— Ahyong & Naiyanetr 2002: 297.—Ahyong et al. 2008: 105, fig. 79–81.— Trivedi et al. 2020: 227. Material examined. FSI/VIZAG/CRUST. 222, 5 males (TL 70–110 mm), 09 females (TL 90–130 mm), 17°46.8’N, 83°28.9’E, 39–44 m, coll. K. Silambarasan, 16 October 2019. Remarks. The present specimen agrees with the description provided by Ahyong (2001), differing in the relative length of the antennular peduncle. In Ahyong’s material, the antennular peduncle was as long as the combined length of the carapace and rostral plate. In our specimen, the combined length of the carapace and rostral plate is 21 mm. Additionally, H. annandalei closely resembles H. sinensis Liu & Wang, 1999 but differs from other species of Harpiosquilla in several features. These include the presence of armed submedian carinae on fifth abdominal segment and the distinctive colour pattern on the distal segment of the uropodal exopod, which is black with a white or yellow median stripe, in contrast to the black inner half and yellowish outer half observed in other species. Moreover, the margins of the large ‘eyespot’ on the telson are sharply defined in H. annandalei, whereas they appear somewhat diffuse in H. sinensis. Distribution. Gulf of Martaban, India, Indonesia, Phuket, South China Sea, Taiwan, Japan, and Australia (Ahyong 2013; Trivedi et al. 2020).
