Diptera Chamaemyiidae), an Overlooked Family of Biological Control Agents
Bulletin of Insectology 68 (2): 173-180, 2015 ISSN 1721-8861 Seasonal habits of predation and prey range in aphidophagous silver flies (Diptera Chamaemyiidae), an overlooked family of biological control agents 1 2 3 1 4 2 Serdar SATAR , Alfio RASPI , Işıl ÖZDEMIR , Adnan TUSUN , Mehmet KARACAOĞLU , Giovanni BENELLI 1Department of Plant Protection, Faculty of Agriculture, University of Çukurova, Balcali, Adana, Turkey 2Department of Agriculture, Food and Environment, Insect Behaviour Group, University of Pisa, Italy 3Plant Health Central Research Institute, Yenimahalle, Ankara, Turkey 4Biological Control Research Station, Yüreğir, Adana, Turkey Abstract Aphids are among the most widespread and serious groups of pests in agro-ecosystems, and predaceous arthropods have been proposed as biological control agents against them, including parasitic Hymenoptera, lacewings, ladybugs, hoverflies and silver flies (Diptera Chamaemyiidae). Chamaemyiidae is a small family of predaceous flies, including aphidophagous and coccido- phagous species. Little is known about their ecology, and partial failures of Chamaemyiidae-based biological control programs against aphids may be due to poor synchronization of predator-prey seasonal habits. In this study, we investigated seasonality of predation and prey range of aphidophagous Chamaemyiidae. A field survey was conducted on crops and indigenous flora in seven agricultural sites in southern Turkey. Seventeen host plant families were surveyed for Chamaemyiidae presence and 371 silver flies were studied. All Chamaemyiidae larvae were observed to prey on adult and young instar aphids in the field. Silver fly total larval abundance reached a maximum in autumn and early winter. Six species were identified: Leucopis annulipes, L. formosana, L. glyphinivora, L. revisenda, L. rufithorax and L. -
Estimating the Evolutionary Rates in Mosasauroids and Plesiosaurs: Discussion of Niche Occupation in Late Cretaceous Seas
Estimating the evolutionary rates in mosasauroids and plesiosaurs: discussion of niche occupation in Late Cretaceous seas Daniel Madzia1 and Andrea Cau2 1 Department of Evolutionary Paleobiology, Institute of Paleobiology, Polish Academy of Sciences, Warsaw, Poland 2 Independent, Parma, Italy ABSTRACT Observations of temporal overlap of niche occupation among Late Cretaceous marine amniotes suggest that the rise and diversification of mosasauroid squamates might have been influenced by competition with or disappearance of some plesiosaur taxa. We discuss that hypothesis through comparisons of the rates of morphological evolution of mosasauroids throughout their evolutionary history with those inferred for contemporary plesiosaur clades. We used expanded versions of two species- level phylogenetic datasets of both these groups, updated them with stratigraphic information, and analyzed using the Bayesian inference to estimate the rates of divergence for each clade. The oscillations in evolutionary rates of the mosasauroid and plesiosaur lineages that overlapped in time and space were then used as a baseline for discussion and comparisons of traits that can affect the shape of the niche structures of aquatic amniotes, such as tooth morphologies, body size, swimming abilities, metabolism, and reproduction. Only two groups of plesiosaurs are considered to be possible niche competitors of mosasauroids: the brachauchenine pliosaurids and the polycotylid leptocleidians. However, direct evidence for interactions between mosasauroids and plesiosaurs is scarce and limited only to large mosasauroids as the Submitted 31 July 2019 predators/scavengers and polycotylids as their prey. The first mosasauroids differed Accepted 18 March 2020 from contemporary plesiosaurs in certain aspects of all discussed traits and no evidence Published 13 April 2020 suggests that early representatives of Mosasauroidea diversified after competitions with Corresponding author plesiosaurs. -

HOVASAURUS BOULEI, an AQUATIC EOSUCHIAN from the UPPER PERMIAN of MADAGASCAR by P.J
99 Palaeont. afr., 24 (1981) HOVASAURUS BOULEI, AN AQUATIC EOSUCHIAN FROM THE UPPER PERMIAN OF MADAGASCAR by P.J. Currie Provincial Museum ofAlberta, Edmonton, Alberta, T5N OM6, Canada ABSTRACT HovasauTUs is the most specialized of four known genera of tangasaurid eosuchians, and is the most common vertebrate recovered from the Lower Sakamena Formation (Upper Per mian, Dzulfia n Standard Stage) of Madagascar. The tail is more than double the snout-vent length, and would have been used as a powerful swimming appendage. Ribs are pachyostotic in large animals. The pectoral girdle is low, but massively developed ventrally. The front limb would have been used for swimming and for direction control when swimming. Copious amounts of pebbles were swallowed for ballast. The hind limbs would have been efficient for terrestrial locomotion at maturity. The presence of long growth series for Ho vasaurus and the more terrestrial tan~saurid ThadeosauTUs presents a unique opportunity to study differences in growth strategies in two closely related Permian genera. At birth, the limbs were relatively much shorter in Ho vasaurus, but because of differences in growth rates, the limbs of Thadeosau rus are relatively shorter at maturity. It is suggested that immature specimens of Ho vasauTUs spent most of their time in the water, whereas adults spent more time on land for mating, lay ing eggs and/or range dispersal. Specilizations in the vertebrae and carpus indicate close re lationship between Youngina and the tangasaurids, but eliminate tangasaurids from consider ation as ancestors of other aquatic eosuchians, archosaurs or sauropterygians.

The First Possible Choristoderan Trackway from the Lower
www.nature.com/scientificreports OPEN The frst possible choristoderan trackway from the Lower Cretaceous Daegu Formation of South Korea and its implications on choristoderan locomotion Yuong‑Nam Lee1*, Dal‑Yong Kong2 & Seung‑Ho Jung2 Here we report a new quadrupedal trackway found in the Lower Cretaceous Daegu Formation (Albian) in the vicinity of Ulsan Metropolitan City, South Korea, in 2018. A total of nine manus‑pes imprints show a strong heteropodous quadrupedal trackway (length ratio is 1:3.36). Both manus and pes tracks are pentadactyl with claw marks. The manus prints rotate distinctly outward while the pes prints are nearly parallel to the direction of travel. The functional axis in manus and pes imprints suggests that the trackmaker moved along the medial side during the stroke progressions (entaxonic), indicating weight support on the inner side of the limbs. There is an indication of webbing between the pedal digits. These new tracks are assigned to Novapes ulsanensis, n. ichnogen., n. ichnosp., which are well‑matched not only with foot skeletons and body size of Monjurosuchus but also the fossil record of choristoderes in East Asia, thereby N. ulsanensis could be made by a monjurosuchid‑like choristoderan and represent the frst possible choristoderan trackway from Asia. N. ulsanensis also suggests that semi‑aquatic choristoderans were capable of walking semi‑erect when moving on the ground with a similar locomotion pattern to that of crocodilians on land. South Korea has become globally famous for various tetrapod footprints from Cretaceous strata1, among which some clades such as frogs2, birds3 and mammals4 have been proved for their existences only with ichnological evidence. -

Diptera Chamaemyiidae) Described by Camillo Rondani: a Revision of Eight Silver Fly Species
Bulletin of Insectology 69 (2): 199-219, 2016 ISSN 1721-8861 On the identity of Leucopis (Diptera Chamaemyiidae) described by Camillo Rondani: a revision of eight silver fly species Alfio RASPI, Giovanni BENELLI Department of Agriculture, Food and Environment, University of Pisa, Italy Abstract The dipterologist Camillo Rondani described a wide number of new Diptera species, including 12 species of silver flies (Diptera Chamaemyiidae). The first Rondani description of Chamaemyiidae was carried out in 1847 in his research “Osservazioni sopra parecchie specie di esapodi afidicidi e sui loro nemici”. Among them, Ochtiphila obscuripes Rondani 1875 was considered by Czerny (1936) synonymous of Chamaemyia geniculata (Zetterstedt 1838). Later on, Raspi shed light on the identity of Leucopis palumbii Rondani 1872 (Raspi, 1983b; 1988); Leucopis bursaria Rondani 1848 (Raspi, 2003) and Ochtiphila frontella Rondani 1875 (Raspi, 2006). In this research, the identity of the other Leucopis species described by Rondani is estabilished. The valid species are Leucopis (Leucopis) aphidivora Rondani 1847, of which Leucopis fiorii Raspi 1986 is a new synonym; Leucopis (Leucopis) aphidiperda Rondani 1848; Leucopis (Leucopis) misaphida Rondani 1848; Leucopis (Leucopis) minuscula Rondani 1875; Leucopis (Leucopis) talaria Rondani 1875; Leucopomyia palliditarsis (Rondani 1875), of which Leucopis alticeps Czerny 1936 is a new synonym. Leucopis (Leucopis) armillata Rondani 1875 is a new synonym of Leucopis palumbii Rondani 1872, and Leucopis ballestrerii Rondani 1875 is a new synonym of Leucopomyia silesiaca (Egger 1862). Overall, concerning the twelve species of Chamaemyiidae described by Camillo Rondani, nine of them are still considered valid species. This study adds basic knowledge to silver fly systematics and has helpful implications concerning Chamaemyiidae-based biological control programs. -

Diapsid Phylogeny and the Origin and Early Evolution of Squamates by Tiago Rodrigues Simões A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in SYSTEMATICS AND EVOLUTION Department of Biological Sciences University of Alberta © Tiago Rodrigues Simões, 2018 ABSTRACT Squamate reptiles comprise over 10,000 living species and hundreds of fossil species of lizards, snakes and amphisbaenians, with their origins dating back at least as far back as the Middle Jurassic. Despite this enormous diversity and a long evolutionary history, numerous fundamental questions remain to be answered regarding the early evolution and origin of this major clade of tetrapods. Such long-standing issues include identifying the oldest fossil squamate, when exactly did squamates originate, and why morphological and molecular analyses of squamate evolution have strong disagreements on fundamental aspects of the squamate tree of life. Additionally, despite much debate, there is no existing consensus over the composition of the Lepidosauromorpha (the clade that includes squamates and their sister taxon, the Rhynchocephalia), making the squamate origin problem part of a broader and more complex reptile phylogeny issue. In this thesis, I provide a series of taxonomic, phylogenetic, biogeographic and morpho-functional contributions to shed light on these problems. I describe a new taxon that overwhelms previous hypothesis of iguanian biogeography and evolution in Gondwana (Gueragama sulamericana). I re-describe and assess the functional morphology of some of the oldest known articulated lizards in the world (Eichstaettisaurus schroederi and Ardeosaurus digitatellus), providing clues to the ancestry of geckoes, and the early evolution of their scansorial behaviour. -

As such they contribute to diverse fauna and are indicators of rich habitats. As part of the effort to document the biodiversity of Costa Rica, we here describe a new species of Meromacrus and provide additional details on the eight other Mesoamerican species. The genus Meromacrus is endemic to the New World the included species ranging from the southern United States to northern Argentina. -
