The giant isopod genus Bathynomus A. Milne-Edwards, 1879, is recorded for the first time in Indonesian waters, from deep waters off southern Java in the Indian Ocean. Bathynomus raksasasp. nov. is described and notes on juvenile specimens of an unidentified species found in the same locality are also provided. Bathynomus raksasasp. nov. is characterized by the large size (averaging at 330 mm), narrowly rounded clypeus apex, prominent longitudinal carina on the clypeus, convex lateral margins of the uropodal exopod and endopod, produced distolateral corners of the uropodal exopod and endopod which have acute ends, an uropodal exopod with a setal fringe of medium length (69%), a pleotelson 1.6 times wider than long with the posterior margin medially concave, and the large number (11–13) of spines on the pleotelson.

The benthic ctenophore Vallicula multiformis Rankin, 1956 is recorded for the first time in the Arabian Sea, from the Gulf of Kutch, west coast of India in March 2013. This occurrence represents a remarkable extension of its geographic distribution that until now included only known the Pacific and Atlantic oceans.

Sergestes edwardsii Kröyer, 1855 species group is composed of 9 species: S. semissis  (Burkenroad, 1940);  S. gibbilobatus (Judkins, 1978);  S. orientalis (Hansen, 1919);  S. geminus (Judkins, 1978);  S. tantillus (Burkenroad, 1940); S. consobrinus (Milne, 1968) California Current Form;  S. consobrinus (Milne, 1968) Central Form; S. edwardsii (Kröyer, 1855); S. brevispinatus (Judkins,1978).  The bathypelagic  shrimps  belonging  to  the  genus Sergestes  are  being studied from the  IIOE  material  for  its  taxonomy  and distribution.  Two species, S. brevispinatus (Judkins,1978) and  S. edwardsii (Kröyer, 1855), have been collected by the research vessels  ANTON BRUNN, ARGO, DIAMANTINA, METEOR, OSHORO MARU and VARUNA in the Indian Ocean for the first time.  Sergestes edwardsii is broadly distributed throughout the tropical Atlantic; it occurs from the New Land Plaza, Canada, to the wide of the Great Power of the North; throughout the Caribbean and Gulf of Mexico. Records at high northern latitudes in the Western Atlantic are probably due to transport by the Gulf Stream (Judkins, 1978). In Brazil it occurs in Para, in the Archipelago of Are Peter and Sao Paulo, Great River of North Fermando De Noronho  (D’Incao, F., 1995, 1998). Specimens of the present material are housed in the Marine Reference Collection and Resource Centre (MRC&RC), University of Karachi.

Tridentella memikat sp. nov., Tridentella tanimbar sp. nov. and Tridentella brandtae sp. nov. are described and figured. T. memikat sp. nov. is the largest species in the family and can be identified by the broadly rounded pleotelson posterior margin, complete lack of dorsal ornamentation and antennule peduncle articles 2 and 3 each with the posterodistal angle produced. T. tanimbar sp. nov. is a sister species to T. recava Bowman, 1986, both species characterised by a flattened body shape, lack of dorsal ornamentation and deep excision to the pleotelson apex; T. tanimbar sp. nov. is identified by free lateral margins to pleonite 5, antennal flagellum extending to pereonite 5 or 6, pleon wider than pereon, the propodus of pereopods 1–3 lacking long slender robust setae, uropod exopod shorter (0.8) than endopod and the uropods not extending beyond the pleotelson. Tridentella brandtae sp. nov. is characterised by the posterior margin of the pleotelson being subtruncate and weakly emarginate; posterior margins of pereonites 6 and 7, pleonites 3–5 and the dorsal surface of the pleotelson weakly nodulose; inferior margins of the propodus of pereopods 2 and 3 with a double row of robust setae; the shape and setation of the uropods; adult males are further characterised by the presence of a large bluntly rounded robust seta at the inferodistal angle of the carpus. These species constitute the first record of the family from the Indian Ocean.

Abstract The eggs of Polka-dot ribbonfish Desmodema polystictum have been recorded for the first time in the Indian Ocean. Although the only previous information on eggs from this species consists of line drawings from 1973 (Pacific Ocean), the identification was possible by combining morphological and molecular analyses. As far as we are aware, only few confirmed records of adult individuals have been previously reported from the Indian Ocean. We found eggs in the proximity of numerous adults (57 and 42 individuals at two stations) indicating that the Central Indian Ocean is potentially an important spawning ground of D. polystictum.

Euroxenus vayssieresi (Bonfils, Attie & Reynaud, 2001) (Issinae, Sarimini) was described (in the genus Borbonissus Bonfils, Attie & Reynaud, 2001) from Réunion Island, in the Indian Ocean and previous to this report has not been recorded elsewhere. Euroxenus vayssieresi is here illustrated and redescribed to improved taxonomic diagnosis. Euroxenus vayssieresi is recorded for the first time from the island of Hawaii in the Hawaiian Archipelago. This is first record of the family Issidae from the Hawaiian Archipelago.

A New Species

The genus Smacigastes Ivanenko & Defaye, 2004 (Harpacticoida, Copepoda) is the most primitive genus in the family Tegastidae Sars, 1904, occurring in deep-sea chemosynthetic environments, such as hydrothermal vents, cold seeps, whale falls and wood falls. Our exploration of the Onnuri Vent Field, the sixth active hydrothermal vent system in the Central Indian Ridge, resulted in the discovery of a new species in the genus Smacigastes. A detailed morphological analysis of S. pumilasp. nov. reveals that it most resembles S. barti Gollner, Ivanenko & Martínez Arbizu, 2008, described from a hydrothermal vent in the East Pacific Ridge; the new species can be distinguished from the existing species by the 8-segmented female antennule, the absence of an abexopodal seta on the antennary basis, the mandibular exopod represented by a single seta and the exopod of the first leg with five setae. This is the first record of Smacigastes in the Indian Ocean. A dichotomous key to species of the genus Smacigastes worldwide is provided.

A new whipray, Himantura randalli sp. nov., described from material collected off Bahrain, Kuwait and Qatar, appearsto be endemic to the Persian Gulf. It has been frequently confused with forms of the more widely distributed whiprayHimantura gerrardi Gray and other presently unidentified species from the Indian Ocean. Himantura randalli sp. nov. isdistinguished from these species by a combination of characters, i.e. disc shape, morphometrics, squamation (includingits rapid denticle development and denticle band shape), plain dorsal disc coloration, and whitish saddles on a dark tail inyoung. It is a medium-sized whipray with a maximum confirmed size of 620 mm disc width (DW) and a birth size ofaround 150–170 mm DW. Males mature at approximately 400 mm DW. Himantura randalli sp. nov. is relatively abundantin the shallow, soft-sedimentary habitats of the Persian Gulf from where it is commonly taken as low-value or discarded bycatch of gillnet and trawl fisheries.
