A new species of the genus Disogmus Förster (Hymenoptera, Proctotrupoidea, Proctotrupidae) from the Eocene Rovno amber

Disogmus rasnitsyni Kolyada & Perkovsky, sp. n. is described from a fossil inclusion of Late Eocene amber (Ukraine). The new species is most similar to Disogmus basalis (Thomson, 1857), in particular, in the shape of the tyloids and the general shortening of the segments of antennae, but distinctly differs from it and the other species of the genus by having tyloids on flagellar segments 2-4 compared to 3-6 and 4-7 in other species.     

A new species of the genus Karnyothrips (Thysanoptera,?Phlaeothripidae) from China

Karnyothrips cyathomorphus sp. n. (Phlaeothripidae: Phlaeothripinae) is described as a new apterous species in the genus Karnyothrips Watson 1923, and it represents the fourth species of the genus to be recorded from China. A key to the Chinese species is given.     

A remarkable new ‘gruiform’ bird from the Middle Eocene of Messel (Hessen, Germany)

Salmila robusta n. gen., n. sp. (Aves: ‘Gruiformes’) is described from the Middle Eocene of Messel (Hessen, Germany). The new species is assumed to have had a predominantly terrestrial habit. It shares derived features of the carpometacarpus with the recent Psophiidae and some taxa of the Cariamae. In several features, however, it distinctly differs from other ‘gruiform’ birds (e. g. in the larger proximal end of the humerus and in the shape of the margo caudalis of the sternum). AlthoughSalmila robusta has been tentatively assigned to the Cariamae in this study, its exact systematic position deserves further investigations. The rather short tarsometatarsus of the new species resembles that of the ‘Messel-phorusrhacid’Aenigmavis sapea Peters 1987.     

New genus of leaf-mimicking katydids (Orthoptera: Tettigoniidae) from the Late Eocene–Early Oligocene of France and England

A new leaf-mimicking katydid (Orthoptera: Tettigoniidae: Pseudophyllinae), Archepseudophylla fossilis gen. et sp. nov. is described based on tegmina from the Early Oligocene of France. Lithymnetes laurenti Théobald, 1937 from the Late Eocene of France is transferred to Archepseudophylla comb. nov. The enigmatic ‘Poekilloptera’ melanospila Cockerell, 1921 from the Early Oligocene of the Isle of Wight (UK) is transferred to Archepseudophylla comb. nov. The present discoveries in the Palaeogene of the Isle of Wight, Céreste, and Marseilles Basins represent the first fossil records of Pseudophyllinae. In addition, these records support warm and humid forest conditions near the palaeolakes of the Isle of Wight, Camoins-les-Bains, and Céreste.     

A synoptic review of the Eocene (Ypresian) cartilaginous fishes (Chondrichthyes: Holocephali,Elasmobranchii) of the Bolca Konservat-Lagerstätte,Italy

Here, we review and discuss the records and taxonomy of the Ypresian (Eocene) chondrichthyans from the famous Bolca Konservat-Lagerstätte in northeastern Italy. Despite the outstanding diversity and the numerous studies focusing on the actinopterygian faunas from Pesciara and Monte Postale, the current knowledge about the systematics, taxonomy and phylogenetic relationships of the cartilaginous fishes from these Eocene sites remains elusive and largely inadequate. The celebrated Eocene Bolca Lagerstätte has yielded several exquisitely preserved articulated remains of chondrichthyan fishes in which delicate structures and soft tissues are preserved, as well as isolated teeth. The cartilaginous fish assemblage of Bolca comprises at least 17 species-level taxa belonging to 10 families in 6 orders, including selachians (Carcharhiniformes, Lamniformes), batoids (Torpediniformes, Myliobatiformes, Rajiformes) and holocephalans (Chimaeriformes). The occurrence of holocephalans represented by an isolated fin-spine of the chimeroid Ischyodus in the Bolca assemblage is reported here for the first time and represents the first record of chimeroids in the Eocene of Italy and also southern Europe. The Bolca chondrichthyan assemblage is remarkably different from those of other contemporaneous Boreal or Tethyan deposits, suggesting that its taxonomic composition is largely influenced by the palaeoenvironmental context. However, this synoptic review also highlights the importance of detailed revisions of all chondrichthyan remains from the Bolca Konservat-Lagerstätten.     

A checklist of the genus Tomosvaryella Aczél (Diptera: Pipunculidae) from the Middle East with the description of a new species

A checklist of 39 species of the genus Tomosvaryella Aczél (Diptera, Pipunculidae) known from the Middle East is provided. A new species, T. hamata Majnon Jahromi &; Kehlmaier sp. n. is described from southern Iran and diagnostic characters of male and female terminalia are illustrated. Tomosvaryella dentiterebra (Collin, 1949 Collin, J. E. (1949): Results of the Armstrong College Expedition to Siwa Oasis (Libyan Desert), 1935, under the leadership of Prof. J. Orner-Cooper. Diptera Empididae, Dolichopodidae, Aschiza and Acalypterae. Bulletin de la Societe Fouad I^erd'Entomologie, 33, 75–225. [Google Scholar]) is redescribed and male and female terminalia are illustrated for the first time. A phylogenetic maximum-likelihood analysis and uncorrected pairwise genetic distances of 18 out of 22 Iranian species of Tomosvaryella based on DNA barcodes of the mitochondrial COI gene are presented and also discussed.

A new species of Phoenicopsis (Leptostrobales) from the Maastrichtian–Danian of Chukotka,Russia

A new species, Phoenicopsis anadyrensis Nosova, is described based on the leaf morphology and cuticle features from the Maastrichtian–Danian Rarytkin Formation, Chukotka, North-East of Russia. It is characterized by hypostomatic leaves with stomatal bands on the abaxial side, undulate anticlinal epidermal cell walls and papillae on the epidermal cells and on the subsidiary cells of the stomata. The new species is the youngest reliable representative of the genus Phoenicopsis. This record extends the stratigraphic range of Phoenicopsis from its previously known latest records in the early Campanian up to Maastrichtian–Danian. The persistence of the genus Phoenicopsis up to the Cretaceous–Paleogene boundary is most likely related with vicinity to mountain floras associated with Late Cretaceous and Paleogene volcanic uplands.     

A new recent genus and species of three‐toed jerboas (Rodentia: Dipodinae) from China: A living fossil?

The new recent genus and species of three‐toed jerboas (Rodentia: Dipodinae), from southern Ningxia, China, is described. This form demonstrated a unique mixture of external, cranial, and dental characters that individually are typical for one or another of all known genera of Dipodinae. Based on morphological characters, it is recovered as the part of Dipodinae tree, distinct from all other members due to its unique combination of morphological characters, and appears to be a nearly ideal living ancestor of all other dipodines. In contrast to morphology, the molecular data indicate a relatively young age for this lineage and consistently place it as the sister group to Stylodipus. The results of the molecular clock analysis suggest that the separation of the two lineages dates back to the Early Pliocene or the Pliocene/Miocene boundary. The estimated geographic range of the new form seems extremely small. The conservational status of the new species remains to be determined; however, the available information suggests that it requires protection.     

Eocene sand tiger sharks (Lamniformes,Odontaspididae) from the Bolca Konservat-Lagerstätte,Italy: palaeobiology,palaeobiogeography and evolutionary significance

Here we report the first record of one of the most common and widespread Palaeogene selachians, the sand tiger shark Brachycarcharias, from the Ypresian Bolca Konservat-Lagerstätte. The combination of dental character of the 15 isolated teeth collected from the Pesciara and Monte Postale sites (e.g. anterior teeth up to 25 mm with fairly low triangular cusp decreasing regularly in width; one to two pairs of well-developed lateral cusplets; root with broadly separated lobes; upper teeth with a cusp bent distally) supports their assignment to the odontaspidid Brachycarcharias lerichei (Casier, 1946), a species widely spread across the North Hemisphere during the early Palaeogene. The unambiguous first report of this lamniform shark in the Eocene Bolca Konservat-Lagerstätte improves our knowledge concerning the diversity and palaeobiology of the cartilaginous fishes of this palaeontological site, and provides new insights about the biotic turnovers that involved the high trophic levels of the marine settings after the end-Cretaceous extinction.     

A new genus and eight new species of the subtribe Anillina (Carabidae,Trechinae, Bembidiini) from Mexico,with a cladistic analysis and some notes on?the?evolution of the genus

One new genus and eight new species of anilline carabids are described from southern Mexico. The new genus, Zapotecanillus gen. n., is established for Z. oaxacanus (type species) sp. n., Z. nanus sp. n., Z. iviei sp. n., Z. ixtlanus sp. n., Z. montanus sp. n., and Z. kavanaughi sp. n. from the Sierra Madre de Oaxaca, Z. pecki sp. n. from the Sierra Madre del Sur, and Z. longinoi sp. n. from the Sierra Madre de Chiapas. A taxonomic key for all described species of Zapotecanillus and a cladistic analysis, based on morphological data, are provided. Morphological, behavioral and biogeographical aspects of the speciation in the genus obtained from the resulting cladogram are discussed.     

A synoptic review of the genus Thaumaspis Bolívar (Orthoptera,Tettigoniidae, Meconematinae) with the description of a new genus and four new species

Two new species of the new genus Athaumaspis gen. n., Athaumaspis minutus sp. n. and Athaumaspis tibetanus sp. n. from Vietnam and China are described. The subgenus Pseudothaumaspis of Thaumaspis is elevated to generic status and another two new species Pseudothaumaspis bispinosus sp. n. and Pseudothaumaspis furcocercus sp. n. are described, the remaining species of Thaumaspis are reviewed and keyed with the four new species.     

New observations on the anatomy and paleobiology of the Eocene requiem shark 2Eogaleus bolcensis (Carcharhiniformes,Carcharhinidae) from Bolca Lagerstätte,Italy

Here we provide new information about the anatomy of the extinct shark 2Eogaleus bolcensis from the early Eocene Bolca Konservat-Lagerstätte. The combination of morphological and dental characters of the three known articulated specimens and a single isolated tooth collected from the Pesciara and Monte Postale sites (e.g., head bulky with rounded snout, pectoral fins of semiplesodic type, cutting-clutching dentition, dermal denticles shell-shaped and of drag-reducing type, caudal fin accounting for one fourth of the entire body length, 135–153 vertebrae) supports the assignment of 2Eogaleus to the family Carcharhinidae and allows us to confirm definitively its distinct taxonomic status from the sympatric carcharhiniform, the triakid 2Galeorhinus cuvieri. Moreover, the analysis of the dermal denticle morphology and the size and maturity age estimates of the studied specimens provide new paleobiological information about 2Eogaleus, suggesting a close association of this small top predator with the tropical shallow-water marine context hypothesized for the Bolca paleobiotopes.     

A small, “wader-like” bird from the Early Eocene of Messel (Germany)

A small bird with a shorebird-like beak and a very long hind toe is described from the Early Eocene of Messel in Germany. Vanolimicola longihallucis, gen. et sp. nov. is one of the few candidate species for a “wading bird” from Messel, that is, a bird that may have foraged along the shoreline of the ancient lake. A few features indicate a relationship to charadriiform birds and Jacanidae (jacanas) in particular, but charadriiform affinities are only weakly supported. In the preserved skeletal elements, V. longihallucis also resembles the taxon Songzia from the Early Eocene of China, which is considered to be a representative of the Ralloidea (rails and allies). A potential biogeographic significance of the new Messel fossil is strengthened by similar fossils from the North American Green River Formation.     

Three new species of Metalasia (Asteraceae–Gnaphalieae) from the Western Cape and an updated key to the genus

Three new species of Metalasia from the Western Cape of South Africa are described; Metalasia tristis A.Bengtson & P.O.Karis, a small shrublet from the Groot Winterhoek Mountains, and Metalasia formosa A.Bengtson & P.O.Karis and Metalasia eburnea A.Bengtson & P.O.Karis both found in the Langeberg Mountains. The morphology and relationships of the three new species are discussed, and an updated key to the genus is provided.     

A new species of the genus Megasis Guenée, 1845 from Turkey (Lepidoptera: Pyralidae)

A new species in the family Pyralidae is described: Megasis kocaki sp. n., of which the adult, head and the male genitalia are illustrated. The new species is compared with the closely allied Megasis hyrcanella Ragonot, 1893.

First fossil record of Discocephalinae (Insecta,Pentatomidae): a new genus from the middle Eocene of Río Pichileufú, Patagonia,Argentina

A new genus and species of Discocephalini, Acanthocephalonotum martinsnetoi gen. n. et sp. n. is described from Río Pichileufú, middle Eocene of Patagonia, Argentina at palaeolatitude ~ 46°S. The new species is the first fossil representative of the Discocephalinae. This taxon is extant in equatorial to subtropical America, and some species reach warm temperate latitudes (Buenos Aires province). The new genus is distinguished from the other genera of Discocephalini by the combination of these characters: interocular width greater than head length; head massive and quadrangular with the anterior margin almost straight; juga touching each other; labrum thick and curved; triangular ante-ocular process extending beyond the eye; broad spine-like antero-lateral process of the pronotum; pronotum explanate and bean shaped; scutellum triangular with a circular tongue reaching the anterior side of abdominal segment 7; and wings well developed with membrane just surpassing end of abdomen.     

A new genus and a new species of Cladorchiidae (Digenea: Dadayiinae) from Podocnemis expansa (Chelonia) of the neotropical region, State of Pará, Brazil

A new species of amphistome digenean from the stomach and intestine of Podocnemis expansa (Pelomedusidae), of the tropical rain forest, from the State of Pará, Brazil, is described and allocated to a new genus ( Oriximinatrema noronhae ). The new species is characterized by the presence of an esophageal bulb, an esophageal extension uncovered by an extension of the pharyngeal sacs, a well-developed cirrus sac, post-bifurcal genital sucker, a ventro-terminal acetabulum with an anterior lip, and medium-sized eggs. This is the first report of a Dadayiinae trematode infecting a reptilian host.
