Sacura sanguinea Motomura, Yoshida & Vilasri

Sacura sanguinea Motomura, Yoshida & Vilasri Figure 8 Sacura sanguinea Motomura, Yoshida & Vilasri, 2017: 291, figs 1–2 (type locality: Andaman Sea, Thailand). Motomura et al. (2017) described Sacura sanguinea from three specimens purchased at Pak Nam Ranong Fishing Port, Ranong Province, Thailand. The specimens apparently had been trawled from the Andaman Sea, but details on habitat, depth and precise locality are lacking. A single individual of the species was collected during the 2013 cruise, and photographed but not retained (Figure 8). The specimen, 95 mm TL was trawled on the 24 November 2013 off the Ayeyarwady Delta, Myanmar, Andaman Sea (14°9.57’ N, 94°23.97’ E) at a depth of 124 m. Photographs of the specimen agree well with Motomura et al. ’s figure 2 of the female paratype of S. sanguinea, particularly in having: a large dark red spot on the dorsal fin between the sixth and tenth spines; a broad yellow stripe from behind the head, this becoming indistinct and red on the middle of the body and extending to the caudal-fin base; and a yellow caudal fin with bright red spots on the central portion of the fin. These coloration characters are sufficient to distinguish S.

New species of the anthiadin genus Sacura (Perciformes: Serranidae) from the Andaman Sea

discussion

Remarks. The generic classification of the anthiadin fishes has been very confused (Randall & Heemstra 2006) and the generic limits of Sacura have not yet been clearly defined (Heemstra & Randall 1979). In their revision of Sacura, Heemstra & Randall (1979: 1 – 2) gave a large number of characters as diagnostic of the genus and all their characters agreed with those of the Andaman Sea specimens described here. These characters are almost the same as those diagnostic of Odontanthias Bleeker 1873 given by Randall & Heemstra (2006). Although no characters separating Sacura from Odontanthias have been published, the absence of teeth below the vomer path distinguishes the genus Sacura from Odontanthias and, on other hand, the pointed snout and large eyes of the Andaman Sea specimens also indicate that the new species should be included in Sacura.
