AbstractFour new species of the methane seep-inhabiting kalenterid bivalve genus Caspiconcha Kelly in Kelly et al., 2000 are described: Caspiconcha basquensis from the late Albian of northern Spain, C. yubariensis from the late Albian of northern Japan, C. raukumaraensis from the late Albian to mid-Cenomanian of New Zealand, and C. lastsamurai from the Campanian of northern Japan. The earliest confirmed record of the genus is known from the latest Jurassic. It reached its maximum diversity in the Albian and declined in diversity and abundance through the Late Cretaceous. The youngest species, C. lastsamurai, is currently known from a single specimen only.UUID: http://zoobank.org/2f84cfd3-216c-4f1b-8c9f-c808a47f7aaa

(Abstract.)The genus Phreoryctes has been known to zoologists since the year 1843, but there is no published account of the reproductive system sufficiently detailed to permit of comparison with other Oligochæta. The gonads (testes and ovaries) and spermathecœ were discovered by Leydig, who did not distinguish between ovaries and testes, owing to the immature condition of the specimens studied. This writer considered that the genital products were evacuated through the nephridia of their segment. The supposition is, however, incorrect, as genital ducts exist. Mr W. W. Smith of Ashburton, New Zealand, forwarded to the author in the spring of 1888 a single specimen of a new species of Phreoryctes, which was described in the Annals and Magazine of Natural History for June 1888 as Phreoryctes Smithii. In that paper the gonads and their ducts were briefly described and figured.

Climatic History

Geographic distributions of freshwater sponges are related to the geological and climatic history of the continents, on the presence of gemmules and the morphological complexity of this resistant body to withstand change. Gemmules are characteristic of the freshwater Families Spongillidae, Metaniidae and Potamolepidae. However, Acanthotylotra alvarengai, Echinospongilla brichardi and a number of other species within the genus Potamolepis do not produce gemmules. Potamolepis is endemic to the Afrotropical region with seven valid species. African freshwater sponges however, are mostly known from a single specimen (the holotype), due to the scarcity of material from these freshwater systems. In the present study, we describe two new species of non-gemmule bearing freshwater sponges from the Neotropical and Afrotropical Regions.

New Form

Rhynchocephalian lepidosaurs, though once widespread worldwide, are represented today only by the tuatara ( Sphenodon ) of New Zealand. After their apparent early Cretaceous extinction in Laurasia, they survived in southern continents. In South America, they are represented by different lineages of Late Cretaceous eupropalinal forms until their disappearance by the Cretaceous/Palaeogene (K/Pg) boundary. We describe here the only unambiguous Palaeogene rhynchocephalian from South America; this new taxon is a younger species of the otherwise Late Cretaceous genus Kawasphenodon . Phylogenetic analysis confirms the allocation of the genus to the clade Opisthodontia. The new form from the Palaeogene of Central Patagonia is much smaller than Kawasphenodon expectatus from the Late Cretaceous of Northern Patagonia. The new species shows that at least one group of rhynchocephalians not related to the extant Sphenodon survived in South America beyond the K/Pg extinction event. Furthermore, it adds to other trans-K/Pg ectotherm tetrapod taxa, suggesting that the end-Cretaceous extinction affected Patagonia more benignly than the Laurasian landmasses.

AbstractWe describe a new chimaeriform fish, Callorhinchus torresi sp. nov., from the uppermost Cretaceous (late Maastrichtian) of the López de Bertodano Formation, Isla Marambio (Seymour Island), Antarctica. The material shows it is distinct from currently known fossil and extant species of the genus, whereas the outline of the tritors (abrasive surfaces of each dental plate) shows an intermediate morphology between earlier records from the Cenomanian of New Zealand and those from the Eocene of Isla Marambio. This suggests an evolutionary trend in tritor morphology in the lineage leading to modern callorhynchids, during the Late Cretaceous-Palaeogene interval.

We describe a new Procellaria petrel species from the late Pliocene of Taranaki, New Zealand. The new species is most similar morphologically to the White-Chinned Petrel (P. aequinoctialis), Spectacled Petrel (P. conspicillata) and the Westland Petrel (P. westlandica). Compared with those taxa, the new species has a deeper and shorter premaxilla, longer coracoid and shorter wings, while its legs are a similar size. Today, New Zealand is the centre of global diversity of the genus, with four breeding species. This is the first fossil species of Procellaria to be described from New Zealand, attesting to a reasonably long history of this genus in the region.

The group of Asian colubrid species morphologically similar to Oligodon taeniatus (Günther, 1861), previously containing only O. taeniatus, Oligodon mouhoti (Günther, 1864) and Oligodon barroni (Smith, 1916), is revised on the basis of variation in external morphology and dentition of 175 specimens. The confused nomenclatural history of O. taeniatus and its name bearing type is discussed. A neotype is described for Simotes quadrilineatus Jan & Sordelli, 1865, a synonym of O. taeniatus. The holotype of Simotes taeniatus var. mouhoti Boulenger, 1914 is identified. Three new species within this group are described. Oligodon pseudotaeniatus spec. nov. is described on the basis of specimens from central Thailand. This species is morphologically similar to Oligodon taeniatus, but differs by the combination of 17 dorsal scale rows at midbody, 8 supralabials, the absence of dark dorsal and tail blotches and the presence of a vertebral stripe edged with black but no dorsolateral stripes. Oligodon deuvei spec. nov. is described on the basis of specimens from southern Vietnam and Laos; it differs from other known species of the group by the combination of 12–15 maxillary teeth, 17 dorsal scale rows at midbody, usually seven supralabials, the absence of dark dorsal and tail blotches and the presence of a broad vertebral stripe, often conspicuously orange or rusty red. This species is most similar to Oligodon barroni but differs from the latter by a higher number of maxillary teeth and the absence of dark dorsal and tail blotches. Lastly, Oligodon moricei spec. nov. is described on the basis of a single specimen from southern Vietnam. It differs from other species by the combination of a broad rusty brown vertebral stripe edged with two broad black stripes, 12 maxillary teeth, 17 dorsal scale rows, a high number of ventral scales, seven supralabials and a dark cloudy or smoky venter. These new species are compared with other species known from the Indo-Chinese Region. The diagnoses of O. taeniatus, O. mouhoti and O. barroni are revised. A key to members of the group is given.

Sphaeropezia leucocheila is described as a new species from New Zealand. Known from a single specimen, its fruiting bodies were consistently associated with a patch of dead and dying leaves in a liverwort colony that included several species of Lepidoziaceae. A phylogenetic analysis places this fungus in Sphaeropezia, a genus that includes several putative parasites of liverworts and mosses from the Northern Hemisphere.

A New Species

New Zealand is a globally significant hotspot for seabird diversity, but the sparse fossil record for most seabird lineages has impeded our understanding of how and when this hotspot developed. Here, we describe multiple exceptionally well-preserved specimens of a new species of penguin from tightly dated (3.36–3.06 Ma) Pliocene deposits in New Zealand. Bayesian and parsimony analyses place Eudyptes atatu sp. nov. as the sister species to all extant and recently extinct members of the crested penguin genus Eudyptes . The new species has a markedly more slender upper beak and mandible compared with other Eudyptes penguins. Our combined evidence approach reveals that deep bills evolved in both crested and stiff-tailed penguins ( Pygoscelis ) during the Pliocene. That deep bills arose so late in the greater than 60 million year evolutionary history of penguins suggests that dietary shifts may have occurred as wind-driven Pliocene upwelling radically restructured southern ocean ecosystems. Ancestral area reconstructions using BioGeoBEARS identify New Zealand as the most likely ancestral area for total-group penguins, crown penguins and crested penguins. Our analyses provide a timeframe for recruitment of crown penguins into the New Zealand avifauna, indicating this process began in the late Neogene and was completed via multiple waves of colonizing lineages.
