A New Species

A new species of stomatopod crustacean, Oratosquillina nordica sp. nov. is described from the Indo-West Pacific region (type locality: Taiwan). It is most similar to O. quinquedentata (Brooks, 1886), with which it has been confused. Oratosquillina quinquedendata is presently known only from the southern hemisphere, and most of its northern hemisphere records are referable to O. nordica. Records of O. quinquedentata from India and Sri Lanka require confirmation, possibly representing a third species. A key to the species of Oratosquillina is provided.

A New Species

We describe a new species, Aspidura desilvai sp. nov., closely resembling A. trachyprocta and the last addition to the genus A. ravanai, from Knuckles massif, Matale District, of Sri Lanka. The species represents the ninth species of the genus known from Sri Lanka, and is readily distinguished from all other congeners by its colour pattern, the scale nature in the ischiadic region, and morphometric characteristics specially from its ratio between the snout to eye distance to its eye width. The species is currently known only from the type locality.

Copepoda Cyclopoida

Abstract A new species of the cyclopoid copepod genus Paramacrochiron, P. tridentatum, which is parasitic on the rhizostome medusa, Versuriga anadyoneme (Maas, 1903), is described from Vietnam. This is the tenth species within the genus. The new species is distinguishable from other congeners by the combination of the following features: (1) female second maxillipedal segment with 3 acutely pointed processes terminally; (2) female leg 4 endopod as long as or slightly longer than exopod; (3) male maxilliped with a small, acutely pointed process at subterminal corner of the first segment and a row of relatively coarse spinules along the inner margin of the second segment. The present study most probably implies a high species diversity of Paramacrochiron in the tropical and subtropical waters of the Indo-West Pacific region.

A New Species

AbstractMost species of the genusPliosaurusOwen, 1842 come from the Northern Hemisphere, however, a growing number of new specimens are now available from the Southern Hemisphere. Here, a new species ofPliosaurusis described, the second for the genus from the Southern Hemisphere, collected from the upper Tithonian (Jurassic) levels of the Vaca Muerta Formation, Neuquén Province, Patagonia.Pliosaurus almanzaensisnew species is characterized by two autapomophies: the angular participating in the mandibular symphysis and the occipital condyle without a notochordal pit or several, irregularly arranged grooves. Additionally,P.almanzaensisn. sp. can be differentiated from otherPliosaurusspecies by the following characters: trihedral teeth, nine or more symphyseal alveoli, 15–17 post-symphyseal alveoli, and the parasphenoid without a ventral keel.Pliosaurus almanzaensisn. sp. shows thatPliosaurusspecies with nine or more symphyseal alveoli persisted until the late Tithonian, contrary to previous assumptions that only species with six symphyseal alveoli were present.

Alpheid Shrimp

A new species of the alpheid shrimp genus Salmoneus Holthuis, 1955, probably an obligate associate of ghost shrimp burrows, is described based on material from Oman (type locality: Darsait near Muscat), Iran and the Philippines. Salmoneus durisi sp. nov. is characterised principally by both chelipeds enlarged, robust, with ventral and dorsal margins of chelae carrying long fine setae, and with minor chela fingers armed with a few large teeth on cutting edges. All specimens of Salmoneus durisi sp. nov. were collected either directly from burrows of larger decapod crustaceans with the aid of a suction pump, or by exposing burrows dug under large subtidal rocks. The Iranian specimen was found together with its presumed host, Neocallichirus calmani (Nobili, 1904). Two additional specimens from Indonesia and the Solomon Islands are tentatively assigned to S. cf. durisi sp. nov., awaiting further studies.

A New Species

A new species of frog tentatively assigned to the genus Polypedates is described from the Gilimale forest reserve of theSabaragamuwa province of Sri Lanka. This tree frog is characterized by unique osteological characteristics in the skullwhich distinguish it from all other congeners, such as the presence of a series of maxillary teeth progressively changingorientation from horizontal to vertical from posterior end to anterior; a laterally-curved spine in the quadratojugal bone;and bony co-ossification on the skull resulting in four dorsal spines which are externally seen as protrusions in the parietalarea. Bioacoustic observations of Polypedates ranwellai sp. nov. revealed three distinct call types. High rates of deforestation and anthropogenic activities at the type locality threaten the survival of the species.

Antennular Peduncle

A new species of hippolytid shrimp, Hippolyte ngi n. sp., is described and illustrated based on specimens collected from the Indo-West Pacific region. The new species clearly belongs to the ‘Hippolyte ventricosa H. Milne Edwards, 1837’ species complex, but is distinguished from its congeners by the dactylus of the last three pereiopods, the position of the hepatic spine, the proportions of the segments of the antennular peduncle, and other subtle but constant features.

A New Species

A new species of the uropeltid snake genus Rhinophis Hemprich, 1820 is described from near Balangoda, southwestern Sri Lanka. Rhinophis mendisi sp. nov. superficially resembles R. homolepis (Hemprich, 1820) in colour pattern and in its prominent, conical tail shield, but differs from that species in having far fewer ventrals (159–177, n = 13 versus > 195 in the types of R. homolepis and its subjective junior synonym R. gerrardi). The five type specimens and one of the referred specimens of the new species were collected probably between 1894 and 1925, and the only known additional, referred specimens (n = 8) were collected from within ca. 30 km of the type locality in 1972. A lectotype is designated for Mitylia gerrardi Gray, 1858, a subjective junior synonym of R. homolepis.

Benthic Animals

Stalked jellyfishes (Cnidaria: Staurozoa) are cryptic, benthic animals, known mainly from polar and temperate waters of the Northern Hemisphere. We describe a new species, Calvadosia lewisi, from South Africa and review the staurozoan fauna of the region. Three other species are previously known from South Africa: Calvadosia capensis (Carlgren, 1938); Depastromorpha africana Carlgren, 1935; and Lipkea stephensoni Carlgren, 1933, but all of these are known from very few records and have been poorly illustrated and documented to date. We provide brief descriptions and photographic illustrations for each species and a list of local and global geographical records. Two (L. stephensoni and C. lewisi), but possibly three (D. africana), of the four known South African staurozoan species are endemic from South Africa. The new species, images, and extra distributional records presented here greatly improve knowledge of the staurozoan fauna in South Africa and, consequently, of the Southern Hemisphere.

A New Species

We describe a new species, Aspidura ravanai sp. nov., representing the eighth species of the genus known from Sri Lanka. The new species is readily distinguished from all other congeners by its colour pattern, scalation, and genetic distinctiveness. Our molecular results indicated that Aspidura began diversifying in the Miocene approximately 18 Ma, and A. ravanai sp. nov. diverged from its likely sister lineage A. trachyprocta at least 6.2 Ma. The species is currently known only from the type locality, on the western slopes of Sri Pada Peak in the central highlands of Sri Lanka.
