DESCRIPTION OF A NEW GENUS AND SPECIES BELONGING TO THE FAMILY PHYLLIDIIDAE (NUDIBRANCHIA: DORIDOIDEA)

A new genus of phyllidiid nudibranch, Reticulidia, is described.Distinguishing features are the reticulate pattern of smoothridges on the dorsum and the radially arranged, glandular discswhich make up the pharyngeal bulb. Additional features of theforegut are described and compared with other genera. The importanceof the alimentary system for the separation of genera withinthe Phyllidiidae is supported and its validity reinforced bythis new genus. One species, Reticulidia halgerda, is describedas new and differentiated from a second, sympatric species.Reticulidia is presently known from the eastern Indian Ocean,South China Sea and western Pacific Ocean. ^*Present address: Australian Biological and Environmental Survey,Australian National Parks and Wildlife Service.

REDESCRIPTION OF PHYLLIDIOPSIS SINAIENSIS (YONOW, 1988) (NUDIBRANCHIA: DORIDOIDEA: PHYLLIDIIDAE), WITH A REVIEW OF THE RED SEA PHYLLIDIIDAE

Phyllidiopsis sinaiensis (Yonow, 1988), of which only one single preservedspecimen had been known, was rediscovered in the northern RedSea. The dorsal colour-pattern of living individuals is presented forthe first time, and the anatomy of P. sinaiensis is describedin detail. Major features of the holotype previously used tocharacterise the species are shown to be artifacts. Principaldistinguishing characters of P. sinaiensis include the centraltubercle ridge, large and multicompound, broad based, pink tubercles,bicoloured black and pink rhinophores, the very elongate muscularoesophageal segment, the distinct stomach and the extremelylong, convoluted prostate that is bound together by connectivetissue. In some specimens, the bases of the tubercles may fuseleading to a predominantely pink dorsum with only a few blacklines. Phyllidiopsis sinaiensis appears to be among the mostcommon nudibranchs in the Gulf of Aqaba. The fact that it has notbeen reported since its original collection in 1980 can be explainedby being confused with the externally similar, well-known speciesPhyllidiella pustulosa (Cuvier, 1804). A review of the phyllidiidfauna of the Red Sea reveals eleven valid species that can allbe identified with the key presented herein. With four out of elevenspecies, phyllidiid endemism (36%) is high in the Red Sea. This isin contrast to recent palaeobiological hypotheses of a post-glacial originof the Red Sea coral reef fauna.     

PHYLOGENY AND BIOGEOGRAPHY OF THE ATLANTIC AND EASTERN PACIFIC HYPSELODORIS STIMPSON, 1855 (NUDIBRANCHIA, CHROMODORIDIDAE) WITH THE DESCRIPTION OF A NEW SPECIES FROM THE CARIBBEAN SEA

A new species, based on two specimens from Guana Island, BritishVirgin Islands, is described. The new species agrees with thegenus Hypselodoris in having a high body profile, a large vestibulargland and mantle glands. It differs from other members of thegenus in the Atlantic Ocean by having a reddish background bodycolour. In addition, dorsal colour patterns such as a broadcentral white line with lateral extensions and the lack of yellowlines or spots further differentiate this species. The radularformula of 52x41.0.41 and a smaller seminal receptacle are alsodistinctive. The phylogenetic relationships of 34 species andsubspecies of Hypselodoris from the eastern Pacific and Atlanticare examined using morphological characters. With the exceptionof the new species, these are characterized by a dark blue backgroundbody colour. The phylogenetic analysis of the data matrix resultedin eight most-parsimonious trees. The resulting consensus treeshows that eastern Pacific and Atlantic species of Hypselodorisconstitute a monophyletic group that is basally split into twosister clades. One clade contains the eastern Pacific speciesand most of the Caribbean species, whereas the other clade containsthe eastern Atlantic species. The new species is the sisterto the rest of the Caribbean species, which also form a monophyleticgroup. This phylogenetic hypothesis suggests that two consecutivevicariant events have affected the biogeography of Hypselodoris:(1) the closure of communication between the tropical Indo-Pacificregion and the Atlantic and eastern Pacific, completed withthe formation of the East Pacific Barrier; and (2) the riseof the Panama isthmus.

中国锄足蟾科掌突蟾属的分类探讨暨一新种描述(Amphibia:Pelobatidae)

本文讨论了掌突蟾属名Leptolalax和Carpophrys的有效性,认为Leptolalax应为有效属名。同时对中国福建、浙江、广西、湖南、贵州、云南等地的L.pelodytoides标本进行了分类研究,结果表明:前五个地区的标本应改订为新种福建掌突蟾L.liui;云南勐养标本仍保留为L.pelodyto-ides此外,峨山掌突蟾L.oshanensis特征明显,不应作为L.pelodytoides的亚种,应保留为种级;文后简述了新种L.liui的主要特征和生态习性资料。     

DESCRIPTION OF EUBRANCHUS LINENSIS NEW SPECIES (NUDIBRANCHIA), WITH REMARKS ON DIAULY IN NUDIBRANCHS

A new species of nudibranch, Eurbranchus liensis, is described,from specimens collected from the southern Iberian Peninsula.The coloration of this species is characterized by the presenceof blood-red patches over the whole body and opaque white pigmentationon the tips of the cerata, rhinophores and oral tentacles, aswell as along the side of the foot. The jaws are denticulateand the triseriate radula has lateral teeth with a small secondarycusp. The rachidian tooth usually has four denticles on eachside. The reproductive system has a prostate and there is astylet at the end of the penis. The diaulic condition in theEubranchidae and in other families of nudibranchs is discussed.

SYSTEMATICS OF ANADYOMENE SPECIES (ANADYOMENACEAE,CHLOROPHYTA) IN THE TROPICAL WESTERN ATLANTIC1

Three new species of Anadyomene are described. Anadyomene lacerata has pinnately branched veins and a unique lacerated margin formed by elongated vein cells. Anadyomene linkiana consists of a perforate blade arising by polychotomous branching from a distinct stripe, and A. howei has an eperforate, delicate blade of polychotomously branched cells and a smooth margin of elongated vein cells. Distinguishing features of the five previously described species are clarified, and all eight taxa are illustrated. Observations in the field and from more than 400 herbarium specimens form the basis for a discussion of Indo-Pacific affinities, ecological adaptations, cell division, reproduction, and ordinal status. A phylogenetic analysis based on 17 equally weighted characters produced a cladistic gradation, indicating that Anadyomene is a monophyletic genus. The most basal species (A. saldanhae, A. linkiana, A. howei, A. menziesii) show only polychotomous branching. In contrast, the distal group (A. pavonina, A. stellata, A. rhizoidifera, A. lacerata) have pinnate interstitial cells along the veins in addition to polychotomous branching at the vein apices.

The new species Spurilla columbina differs from its Europeancongeners in coloration and the shape of its cerata. Comparativedata derived from S. norvegica (Odhner, 1939), S. coerulescens(Laurillard, 1830) and S. verrucicornis (Costa, 1864) are tabulated. ^* T. E.

A REVISION OF THE DEEP-WATER OCTOPUS GENUS SCAEURGUS (CEPHALOPODA: OCTOPODIDAE) WITH DESCRIPTION OF THREE NEW SPECIES FROM THE SOUTHWEST PACIFIC OCEAN

Deep-water trawl surveys on seamounts around New Caledonia yielded62 specimens of the little-known genus, Scaeurgus. Members ofthis genus of octopuses typically occur at depths of 200–500m in temperate and tropical latitudes worldwide. Prior to thisstudy, Scaeurgus was considered to contain one to two species.The new material from New Caledonia contained a surprising diversityof Scaeurgus species from a small area: three distinct new speciesare described and limited material of a further two taxa isreported. A pygmy member of this genus is reported for the firsttime. Distributions of these new taxa are consistent with reportsof high endemism on the seamount systems in this region. Fifty-eightof the 62 specimens were collected from seamounts, with fourof the five taxa unique to a single seamount. (Received 12 January 2004; accepted 28 January 2005)
