A New Species

A deep-sea species of snake eel (family Ophichthidae, subfamily Ophichthinae) Ophichthus mccoskeri sp. nov. is described based on 6 specimens (331–447 mm total length) trawled at 314–363 m depth in Andaman waters, India. This species is differentiated from its deep-water congeners by a combination of characters such as its large eyes, dorsal-fin origin a short distance behind pectoral-fin tip, anal fin black posteriorly, three preopercular pores, maxillary and mandibular teeth ending as triserial, and in a vertebral formula of 20/55/153.

A new species of snake eel, Ophichthus chennaiensis sp. nov. (Anguilliformes: Ophichthidae: Ophichthinae), is described on the basis of a specimen collected from dumped fish disposed of by bottom trawlers at Kasimedu fishing harbour, Chennai. Ophichthus chennaiensis sp. nov is distinguished from its congeners by having its dorsal-fin origin one pectoral-fin length behind the pectoral-fin tip, preanal length 2.4 in TL, biserial maxillary, uniserial mandibular teeth, biserial to uniserial vomerine teeth, and its vertebrae (predorsal 19, preanal 53, and total vertebrae 154).

A New Species

Parmaturus nigripalatum, a new species of catshark of the genus Parmaturus is described from a single specimen collected from a deep-water shark longliner operating in south Sumbawa waters, Indonesia. This new species is distinguished from its closest geographic congener P. lanatus by having prominent enlarged caudal crests, well-developed labial furrows with the uppers and lowers of equal lengths, mouth roof blackish with dark pores, first dorsal fin origin more posteriorly positioned on body trunk, and much lower tooth counts than all other known Parmaturus species. This is the second Parmaturus species recorded from Indonesian waters.

A New Species

A new species of slipper lobster of the genus Petrarctus Holthuis, 2002 was discovered from southwestern India during a survey of deep sea crustaceans. The new species closely resembles P. veliger Holthuis, 2002 from the Andaman Sea and western Pacific but differs mainly in the color marking on abdominal somite I, having a relatively lower cardiac tooth but with better developed tubercles on the abdomen, as well as a differently shaped anterior part of the thoracic sternum. Molecular genetic analysis also confirms the distinct taxonomic status of the new species. To fix the identity of the type species of the genus, a neotype of P. rugosus (H. Milne Edwards, 1837) was selected from a recently collected Indian specimen with color and genetic information.

Rrna Sequences

A new snake eel, Pisodonophis sangjuensis, is described based on 24 specimens collected from the South Sea of Korea (water depth 5–100 m) between 2005 and 2010. This species is characterized by the following morphological features: fleshy protrusions before and behind the posterior nostril; 1–2 regular rows of conical teeth in both jaws, prevomer and vomer are slightly separated from each other; the origin of the dorsal fin above the middle of the pectoral fin; and the pectoral fin is rounded and not elongated. Pisodonophis sangjuensis is most similar to P. cancrivorus in morphology, but the two species differ in their teeth shape (conical in P. sangjuensis vs. granular in P. cancrivorus), and their numbers of vertebrae (143–153 vs. 153–164, respectively). Pisodonophis sangjuensis differs from P. boro in the origin of the dorsal fin (above the middle of the pectoral fin in P. sangjuensis vs. far behind the pectoral fin in P. boro), their numbers of vertebrae (143–153 vs. 170–177, respectively), and their teeth shape (conical in P. sangjuensis vs. granular in P. boro). Pisodonophis sangjuensis is also easily distinguishable morphologically from the remaining seven Pisodonophis spp. worldwide. Molecular analysis using mitochondrial DNA 12S rRNA sequences supported that P. sangjuensis is a new species because of the considerable genetic distance from what appears to be its most closely related species, P. cancrivorus (d=0.068).

A new species of the genus Osteobrama is described from the Mahanadi River, Tikarpada, Angul District, Odisha state, India. Osteobrama tikarpadaensis, new species, differs from its congeners in having two pairs of minute barbels; iii–iv unbranched dorsal-fin rays with 25–33 serrae on the last unbranched ray; 15–16 branched pectoral-fin rays, and 25–27 branched anal-fin rays. The status of Osteobrama dayi is discussed and shown to be a valid species. A key to the species of the genus is provided.

A new species of deepwater gurnard, Pterygotrigla (Otohime) madagascarensis sp. nov. is described, based on two specimens collected on the upper continental slope south of Madagascar, in the southwestern Indian Ocean. The new species belongs to the tropical Indo-Pacific subgenus Otohime in having a short rostral projection, short posttemporal spine, long opercular spine and no cleithral spine. It is most similar to P. (O.) multipunctata, and P. (O.) urashimai, in having no large blotch on the first dorsal fin, a jet-black blotch and no white ocellus on the inner pectoral-fin surface, with no scales on the breast and front of the pectoral-fin base. However, the new species differs from the latter two species by the combination of the following characters: first dorsal-fin spines 7, second dorsal-fin rays 12, dusky rays on the inner pectoral-fin surface, one row of blackish botches on second dorsal fin, and no papillae on the dorsal surface of oral cavity. A key is provided for the twelve Pterygotrigla species now in the subgenus Otohime.

Plectranthias cruentus new species is described from the holotype and two paratypes collected off Ball’s Pyramid and a paratype from Lord Howe Island. It resembles P. pelicieri Randall & Shimizu 1994 in live coloration and most morphological details, including absence of predorsal scales anterior to the supratemporal commissure, but differs in having the fifth or sixth (versus third) dorsal-fin spine longest, at least some pectoral-fin rays branched (versus all unbranched), and inconspicuous (versus distinct) serrations on the interopercle. It also differs in live coloration details.

A new species of the snapping shrimp genus Alpheus Fabricius, 1798, A. longipalma, is described and illustrated on the basis of material from Kagoshima Bay, Kyushu, Japan. It is referred to the A. brevirostris (Olivier, 1811) species group, and appears closest to A. macroskeles Alcock & Anderson, 1894, known with certainty from the Bay of Bengal and Andaman Sea, and A. talismani Coutière, 1898 from the eastern Atlantic. The greatly elongate minor cheliped in males, being subequal to or longer than the major cheliped with proportionally shorter dactylus distinguish the new species from A. macroskeles. The less elongate antennular peduncle and better-developed, rounded distal lamella of the antennal scaphocerite differentiate the new species from A. talismani. All specimens of the new species were trawled from depths greater than 200 m.
