Two new species of deepwater flathead Bembras Cuvier, 1829 from the Andaman Sea, eastern Indian Ocean

A new splendid perch, Grammatonotus bianchi sp. nov. is described on the basis of two specimens (45.9–68.7 mm SL) collected at 184 m depth in the Andaman Sea off the coast of Myanmar during bottom surveys conducted by the R/V Dr Fridtjof Nansen in 2018. The new species can be distinguished from all congeners by its large head (37.7–38.6% SL), large orbit (14.4–15.3% SL), caudal-fin shape, and fresh coloration. A key to Indian Ocean species of Grammatonotus is provided.

Two new species of Leptarma, L. dispersum n. sp. and L. reunionense n. sp. are described from Europa Island and Réunion Island, respectively. Genetically, based on the mitochondrial COX1 gene, both species are markedly divergent from other congeneric species. Phylogenetically, L. dispersum n. sp. shows close relationship with L. lenzii (De Man, 1895) while L. reunionense n. sp. clusters with L. aurifrons (Li, Ng & Shih, 2019) and the species pair L. moluccense (De Man, 1892) and L. paucitorum (Rahayu & Ng, 2009). Morphologically, the new species differ most significantly from congeners by the relative length of the ambulatory legs and the shapes of the first gonopods and carapace. After the description of these two new species, the number of species comprised in the genus Leptarma is raised to 20, four of them being distributed in and off East Africa.

Fish Prey

Feeding habit of tuna in Indian Ocean has been described around Sri Lanka, Indian Waters, Andaman Sea, western Indian Ocean (Seychelles Islands), western equatorial Indian Ocean whereas the tunas feeding habit study in Eastern Indian Oceanis merely in existence. The purpose of this study is to investigate the stomach content of three tuna species (bigeye tuna, yellowfin tuna, and skipjack tuna), apex predator in the southern part of Eastern Indian Ocean. The study was conducted in March – April, 2010 on the basis of catches of commercial tuna longline vessel based in Port of Benoa. A total of 53 individual fishes were collected, consisting of bigeye tuna (Thunnus obesus), yellowfin tuna (Thunnus albacores), and skipjack tuna (Katsuwonus pelamis). Stomach specimens were collected and analyzed.Analysis was conducted on the basis of index of preponderance method. The diet of the three tuna species showed fishes as the main diet (56–82%), followed by cephalopods (squids) as the complementary diet (0–8%), and crustaceans (shrimps) as the additional diet (2–4%). Fish prey composed of 6 families i.e. Alepisauridae, Bramidae, Carangidae, Clupeidae, Engraulidae, and Scombridae.

Two New Species

A biodiversity workshop under the title “International Workshop on the Crustacea of the Andaman Sea” was held at Phuket Marine Biological Center (PMBC), Phuket, Thailand, from 29 November to 20 December 1998 in the framework of the Thai-Danish BIOSHELF programme, running from 1996 to 2000. Material of the decapod crustacean families Callianassidae Dana, 1852 and Upogebiidae Borradaile, 1903, collected in 1996 and 1998, has been made available for study. As a sequel to the report on the callianassid collections, published in 2002 (Phuket Marine Biological Center Special Publication,23(2): 461-532 [2002]), the upogebiid collections, are treated in the present paper, with as a result records of seven species of the genusParagebiculaSakai, 2006, including five new species, and three species of the genusUpogebiaLeach, 1814, including two new species. All species are presented in revised keys to the subfamilies, genera, and species of the family Upogebiidae Borradaile, 1903.
