Discovery of the Puparia of a Whitefly Species Found on Malvaceae in the Pliocene Rajdanda Formation, Jharkhand, Eastern India

A new genus and species of fossil whitefly, Praealeurolobus indicus gen. et sp. nov., is described and illustrated based on puparia found on leaves of a malvaceous plant from the Pliocene Rajdanda Formation in Eastern India. It is the first record of whitefly puparia on leaves from the Neogene deposits of Asia and the second taxon formally named and described from such adpression fossils. The cephalothorax of some of the puparia has a large, irregularly shaped hole with jagged edges, typical of the emergence holes of parasitoids of modern-day whiteflies and represents the earliest record of parasitism on whiteflies. This finding enriches our knowledge of the fossil record of Aleyrodidae in connection with allied fossils and provides new insight into the ecological interactions of the palaeobiota and taphonomy of fossils preserved in the Pliocene Rajdanda Formation.

Miocene Equisetum tubers from the Wulan Basin, Northeast Qinghai-Tibetan Plateau and their paleoecological significance

Equisetum fossils are often reported from the Cenozoic strata in the Northern Hemisphere, but their occurrence in the Qinghai-Tibetan Plateau (QTP) region is scarce. In this investigation, two new species of tuber fossils of Equisetum — Equisetum wulanense Zhang and Xie, n. sp. and Equisetum kekeense Zhang and Xie, n. sp. from the Miocene Youshashan Formation of the Wulan Basin, Qinghai Province are reported. The extant Equisetum plants are usually living in wet habitats. Therefore, fossil species, E. wulanense and E. kekeense, were likely to live in moist environments during Miocene too. The discovery of E. wulanense and E. kekeense in the late Middle Miocene (∼13.4 Ma) indicates that the local climate of the Wulan Basin was more favorable during this period. This new finding confirmed the previous view that the Neogene aridification in the northern QTP was varying: the climate in the Early Miocene and the Middle Miocene were relatively warm and humid and then the climate gradually became colder and drier since the Late Miocene. It is widely accepted that the uplift of the QTP intensified the trend of cooling and drying since the Late Miocene, and eventually formed a cold and dry climate pattern in the northeast margin of the QTP. The discovery of Equisetum fossils in this investigation improved our understanding on the Cenozoic diversity of Equisetum plants in the northern QTP, as well as on the paleoecological environments of the Wulan Basin in Miocene.

New holozoans with cellular resolution from the early Ediacaran Weng'an Biota, SW China

Embryo-like fossils from the early Ediacaran Weng'an Biota (SW China, 609 myr ago), widely interpreted as holozoans, potentially provide insights into the early evolutionary development of metazoans and the rise of the animal kingdom. However, the biodiversity of the embryo-like fossil assemblage is largely underestimated and its more precise phylogenetic affinities within the holozoan tree are still under debate. We describe a new species of embryo-like fossil, Ostiosphaera rara n. gen. n. sp., from the Ediacaran Weng'an Biota. These 3D, phosphatized specimens exhibit a spherical morphology, a thick ornamented envelope with a circular opening and a membrane-bound, multicellular inner body. In terms of biological characteristics, O. rara shows similarities with a number of extant and fossil analogues, including testate amoebae, unicellular green algae, the cellular slime mould Fonticuida and co-occurring Weng'an embryo-like fossils. Although the phylogenetic affinity of O. rara is difficult to constrain precisely based on the available evidence, it is reasonable to follow the holozoan interpretation for these fossils because they share the same grade complexity with co-occurring embryo-like fossils, such as Megasphaera and Helicoforamina , in terms of the combination of biological features. These new holozoans resemble asexual reproductive gemmules of fossil and living demosponges in size, morphology, circular opening and cellular anatomy. If this similarity reflects biological affinity rather than convergent evolution, this discovery would force us to rethink the evolutionary history of Precambrian sponges.

A New Species of Pennsylvanian Plant Fossil (Cyclopteris N.Sp.) from the Placid Shale Member, Brad Formation, Near Ranger, Eastland County, Texas

A new species of Cyclopteris sensu was discovered in the upper sandstone beds of the Placid Shale. New species is distinguished by chevronate veins present between major radiating veins characteristic of Cyclopteris. Discovery of this species expands this genus into the Carboniferous delta deposits of Central Texas, and demonstrates the need to revisit these classic sites.

First record and a new species of the fossil dragonfly genus Proinogomphus (Odonata: Liassogomphidae) from the Early Jurassic of Bascharage in the Grand Duchy of Luxembourg.

A new species of fossil dragonfly, Proinogomphus kreuzerorum sp. nov. (Liassogomphidae), is described from the Early Jurassic black shale of Bascharage in the Grand Duchy of Luxembourg, based on a very well-preserved isolated female hind wing. This genus was previously only known from the Liassic of Braunschweig region in Germany, and is here recorded for the first time for this fossil locality. The classification of the family Liassogomphidae Tillyard, 1935 and the genus Proinogomphus Cowley, 1942 is briefly discussed and the diagnosis of the latter is emended.

Two new species of fossil Eomerope (Mecoptera: Eomeropidae) from the Ypresian Okanagan Highlands, far-western North America, and Eocene Holarctic dispersal of the genus

AbstractTwo new species of Eocene Eomerope Cockerell (Mecoptera: Eomeropidae) are described from the Ypresian Okanagan Highlands deposits of British Columbia, Canada: Eomerope simpkinsaenew species from the Allenby Formation near the town of Princeton, and Eomerope eonearcticanew species from the McAbee locality near the towns of Cache Creek and Ashcroft. Eomerope eonearctica is very close to the coeval Eomerope asiatica Ponomarenko from Primorskiy Kray in Pacific-coastal Russia, consistent with Eocene intercontinental dispersal, which is well documented in numerous plant and animal taxa.

Two new species of fossil Corethrella Coquillett from Late Eocene Rovno amber, with a species‐level phylogeny for the family based on morphological traits (Diptera: Corethrellidae)

AbstractSpecies in the genus Corethrella Coquillett, the only genus in the family Corethrellidae, feed on the blood of frogs and toads and are unique among Diptera in locating their hosts by sound. Their fossil record goes back to the Cretaceous and comprises seven previously described species from various amber deposits. Herein, we present the first records of Corethrella from Late Eocene Rovno amber (35 Ma), with the description of two new species: Corethrella sontagae sp.n. based on a single male, and Corethrella rovnoensis sp.n. based on a single female. A revised key to fossil species of Corethrella is given. Phylogenetic relationships within Corethrella are investigated based on Bayesian and parsimony analysis, including the new data. All species groups recognized by Borkent (2008) are recovered as monophyletic, with the exception of the drakensbergensis group, which is found to be a paraphyletic grade. Both of the newly described species can be accommodated within modern species groups: C. sontagae shows affinities with the quadrivittata group and C. rovnoensis with the rotunda group.This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:AE394C59‐775F‐42DC‐A5A8‐AF9C91E16464.

A NEW GENUS AND SPECIES OF THE FAMILY TRACHYPACHIDAE (COLEOPTERAN, ADEPHAGA) FROM THE UPPER LADINIAN (MIDDLE TRIASSIC) OF MONTE SAN GIORGIO

A new genus and species of fossil Trachypachidae Praedodromeus sangiorgiensis gen. n sp. n. (Coleoptera, Trachypachidae, Eodromeinae), with well developed asymmetrical mandibles, shorter than the head, subrectangular pronotum and slender tibiae, longer than femora, is described from the Kalkschieferzone (uppermost member of the Meride Limestone) of the Swiss side of Monte San Giorgio. Trachypachidae are terrestrial Coleoptera well represented in the Mesozoic fossil record by the extinct family Eodromeinae. Up to now, more than 33 fossil species belonging to 13 genera of Eodromeinae have been described. The new species is part of a collection of fossil insects that includes members of at least six different orders. Based on the ecology of corresponding extant taxa, this insect assemblage provides new insights on the paleoenvironment of Monte San Giorgio area during the Late Ladinian. The assemblage includes terrestrial taxa that support the presence of emerged land and taxa with long-lasting aquatic larval stage (as Plecoptera and Ephemeroptera) that confirm the presence of stable fresh water basins.

New species of Agriotherium (Mammalia, Carnivora) from the late Miocene to early Pliocene of central Myanmar

Here we describe a new species of giant short-faced fossil bears, Agriotherium myanmarensis sp. nov. (Ursidae, Carnivora), from the latest Miocene to early Pliocene Irrawaddy sediments in the Chaingzauk area, central Myanmar. A. myanmarensis has a short mandible and a deep premasseteric fossa, both of which are the typical feature of Agriotherium. There are two specimens discovered so far: in the type specimen the inferior border of the mandibular corpus is rectilinearly-shaped, the m1 talonid is rather reduced, m1 metaconid larger than the entoconid–entoconulid ridge, the diastema between canine and p4 is very short, and the postcanine teeth are so reduced that existing cheek teeth are very crowded. Agriotherium had been widely distributed from the late Miocene through Pleistocene in Europe, East Asia (China), North America, and South Africa, but no fossil record has been reported from Southeast Asia. Except its extreme short snout, A. myanmarensis is most similar to that of the European form, Agriotherium insigne, rather than to the Asian species from Siwalik or China, such as Agriotherium palaeindicus, Agriotherium sivalensis, and Agriotherium inexpetans, suggesting the phylogenetic closeness to the European rather than to the South/East Asian forms.

Early Cretaceous mesofossils from Portugal and eastern North America related to the Bennettitales‐Erdtmanithecales‐Gnetales group

Four new genera and six new species of fossil seed (Buarcospermum tetragonium, Lignierispermum maroneae, Lobospermum glabrum, L. rugosum, L. stampanonii, Rugonella trigonospermum) are described from five Early Cretaceous mesofossil floras from Portugal and eastern North America. The four genera are distinguished by differences in size, shape, and details of seed anatomy, but all are unusual in having an outer seed envelope with a distinctive anatomical structure that surrounds the nucellus and the integument. The integument is extended apically into a long, narrow micropylar tube. The four new genera are part of a diverse, but previously unrecognized, complex of extinct plants that was widespread in Early Cretaceous vegetation and that coexisted in similar habitats with early angiosperms. The distinctive structure of these seeds, and the strong similarities to other fossil seeds (Ephedra, Ephedripites, Erdtmanispermum, Raunsgaardispermum, and some Bennettitales) already known from the Early Cretaceous, suggests that this newly recognized complex of extinct plants, together with Bennettitales, Erdtmanithecales, and Gnetales (the BEG group), is phylogenetically closely related.

Carnegie Museum

THE forty-seventh annual report of the Carnegie Museum covers the year ended December 31, 1944, and includes the financial statement as well as a note on publications and on the library and museum (Carnegie Institute, Pittsburgh). Several projects in the field were either sponsored or conducted by the Museum. Dr. A. C. Twomey and Mr. O. F. von Fuehrer visited the west coast of Hudson Bay, near Churchill, where they secured a splendid set of caribou and a few birds of special interest. Dr. J. LeRoy Kay and Mr. J. K. Doutt spent two months in Montana, where they obtained the best collection of big game mammals which the Museum had collected in one venture. In researches in vertebrate palæontology in Montana during the summer months on a somewhat different plan from that of preceding years, numerous new species of fossils were collected, and the material on certain Tertiary forms like marsupials and insectivores from a type locality of the Pipestone Springs Chadron formation was practically doubled. Preliminary plans were made for a far-reaching project for a biological exploration on the northern sector of Labrador or the Ungava Peninsula. The most spectacular display of the year in the galleries was devoted to an interpretation of the Asiatic and Pacific theatres of war from the point of view of the natural history and the distribution of indigenous peoples. The growth of the collections and researches based on a series of scientific specimens have steadily advanced, and some improvements have been made in the laboratories. Educational services were somewhat reduced in scope owing to transport difficulties but were carried on substantially as before. The director's report is supplemented by more detailed sectional accounts of developments and activities.
