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.

ABSTRACTRecords of flying Jurassic reptiles are very scarce in the Southern Hemisphere. Upper Jurassic pterosaurs have been discovered in marine Tithonian sediments of the Vaca Muerta Formation, in the Neuquén Basin, Patagonia, Argentina. Only four specimens are known so far: the first from Arroyo Picún Leufú, and the other three from the lithographic limestones of Los Catutos. Here, we update knowledge of Late Jurassic pterosaurs from northwest Patagonia. We revise the diagnosis and description of a previously described pterodactyloid, which is named as a new genus and species, Wenupteryx uzi. This small-sized pterosaur shows affinities with Euctenochasmatia or Archaeopterodactyloidea, and represents the most complete Jurassic pterosaur so far known from the Southern Hemisphere. We also report a recent finding suggesting that the new specimen belongs to a new species of pterodactyloid pterosaur. These records show that at least three different taxa of pterosaurs coexisted in the Neuquén Basin: Herbstosaurus, Wenupteryx and a more derived pterodactyloid that represents the largest pterosaur known from the Upper Jurassic of Gondwana.

A New Species

A new species of Crocodyliformes, Sunosuchus junggarensis, is established on the basis of six individuals from the Upper Jurassic of the Junggar Basin, Xinjiang, northwest China. It differs from other species of Sunosuchus primarily in having a dorsoventrally depressed supraoccipital that, in occipital view, lacks a median crest; a frontal that is ridged anteriorly; a distinct depression distal to the foramen aëreum on the dorsal surface of the quadrate; and an elongate, undivided maxillary depression. Cranial ontogenetic variation in S. junggarensis is discussed. Sunosuchus is probably a goniopholidid crocodyliform. It is distinguished from other genera of the Goniopholididae by a narrow and elongate snout, a small skull table, a partially ridged frontal, a pair of anteriorly located anterior palatal fenestrae, a lateroventrally–mediodorsally expanded retroarticular process, some enlarged pits on the frontal, and an elongate mandibular symphysis, with the splenial forming a small part of it. Sunosuchus, Eutretauranosuchus, and some species of Goniopholis may form a monophyletic group within the Mesoeucrocodylia.

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.

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.

Tertiary Period

The occurrence of fossil reptiles in the Lower Miocene of Moghara in Egypt has already been referred to in a paper published in the last volume of this journal (1899, p. 481), where a short account of the deposits in which the remains are found has been given. The specimens which have been received from Captain H. G. Lyons, R.E., Director-General of the Egyptian Geological Survey, include bones and scutes of Crocodile, Trionyx, and of the Chelonian which forms the subject of the present notice. Of the two former the remains are too imperfect for determination, and further material is desirable; but in the case of the last it has been found possible to reconstruct the plastron and most of the carapace, and from these it can be shown that this Chelonian belonged to the Pleuradiran group, and is referable to the genus Podocnemis, forming a new species, to which the name Podocnemis ægyptiaca may be applied. At the present day the genus is found only in South America and Madagascar, but, as in many other cases in which the modern representatives of a group are confined to the Southern Hemisphere, where they may occur in widely separated areas, in the Tertiary period species existed in the Northern Hemisphere.

AbstractBryoria araucana sp. nov. is described from Chile on the basis of morphological, chemical and molecular data. It has a grey to dark greyish brown pendent thallus with the base usually black, branching angles mainly obtuse, terminal branches with few lateral branchlets acutely inserted, fumarprotocetraric acid, and often protocetraric and confumarprotocetraric acids. It is morphologically similar to the Northern Hemisphere B. trichodes, but lacks soralia and has inconspicuous concolorous or slightly darker pseudocyphellae. Bryoria glabra is also reported for the first time from the Southern Hemisphere. New phylogenetic data based on ITS, mtSSU and MCM7 analyses suggest that Bryoria sect. Bryoria is polyphyletic and needs revision.

A New Species

The small polychaete family Trochochaetidae is monogeneric and had been recorded almost exclusively in the northern hemisphere before this study. During a benthic investigation in the coastal shelf zone off Angola at 15°S several specimens were collected from 84 m depth differing from other members of the family and we described it as a new species herein. The only known African species so far was Trochochaeta kirkegaardi from the eastern Atlantic. Trochochaeta ankeae sp. nov. is characterized by having four minute eyes, a small conical antenna, a nuchal crest projecting through chaetiger 2, by lacking notochaetae on chaetiger 2, by having acicular spines on neuropodia 2 and 3 and a pair of conical papillae ventral on abdomen. A key to all 11 known species (including an unnamed one) is given.

Specimens of Andreaea sect. Andreaea collected in Lesotho show morphological differences from the remaining Sub-Saharan Africa species in the group. Particularly, Lesotho specimens have much larger spores, a character diagnostic in the genus. Spore size also separates the Lesotho specimens from typical A. rupestris from the Northern Hemisphere. Consequently, we describe a new species from the highlands of Lesotho (Andreaea barbarae). Additionally, we present a taxonomic key to all accepted species of Andreaea sect. Andreaea in sub-Saharan Africa.

Zatypota albicoxa (Walker) is newly recorded from Mt. Merapi, Java Is., Indonesia. This is the first record of Z. albicoxa from this part of the Oriental region and from the Southern Hemisphere, and the first record of the genus Zatypota from Southeast Asia. The Indonesian population of Z. albicoxa attacks a theridiid spider of the genus Parasteatoda, as do populations of Z. albicoxa in other regions. The spider is a new species, and is described under the name of Parasteatoda merapiensis.

The discovery of a new species,Cyclolampas altusnew species in the upper Callovian of Burgundy (France) leads to the systematic revision of the rare echinoid genusCyclolampasPomel, 1883. Two morphometric approaches are used jointly to describe and quantify variations in test shape: the analysis of linear measurements and the Elliptic Fourier shape analysis. Both analyses yield congruent results that highlight the amplitude of within-species variations and quantify the part due to allometry. Along with the description ofC. altus, the systematic position of species formerly assigned to the generaPygorhytisPomel, 1883 andCyclolampasis amended. Previously attributed to the genusPygorhytis,Cyclolampas castanea(Desor, 1858) is reassigned to the genusCyclolampason the base of new observations. Conversely, the examination of the Bajocian speciesPygorhytis kiliani(Lambert, 1909) andPygorhytis gillieroniDesor in Desor and de Loriol, 1872, which were previously assigned toCyclolampasnow supports their taxonomic reassignment to the genusPygorhytis. Finally, the two speciesCyclolampas verneuili(Cotteau, 1870) andCyclolampas cotteauiMintz, 1966 (nomen nudum) are considered junior synonyms of the genus type speciesCyclolampas voltzii(Agassiz, 1839). The questioned origin date of the genus, estimated either to the Bajocian or to the Oxfordian, is now clearly established to be upper Callovian. These new results fit well with the overall scheme of atelostomate echinoid evolution and migration to deep-sea environments during the Middle and Upper Jurassic.
