Remains of sea turtles from the Ikovo locality (Lugansk Region, Ukraine; Middle Eocene)

Fragmentary remains of sea turtles (Cheloniidae sensu lato: Argillochelys sp., Puppigerus nessovi Averianov, 2005, and Cheloniidae gen. indet.) from the Ikovo locality (Lugansk Region, Ukraine; Lower Lutetian, Middle Eocene) are described. The genera Argillochelys and Puppigerus are recorded for the first time in Eastern Europe. The turtle assemblage from Ikovo is similar at the generic level to West European assemblages (Belgium, Great Britain) of approximately the same age (Lower-Middle Eocene). In the presence of P. nessovi, the Ikovo assemblage is similar to that from the Middle Eocene Dzheroi 2 locality (Uzbekistan).     

New and little-known orthopteroid insects (Polyneoptera) from fossil resins: Communication 4

New taxa of Ensifera and Caelifera orthopterans (Insecta, Orthoptera), from the families Gryllotalpidae [Marchandiinae, subfam. nov. (Lower Cretaceous)], Haglotettigoniidae [?Haglotettigonia aenigmatosa, sp. nov. (Lower Cretaceous)], Tettigoniidae [Meconematinae: Archixizicus occidentalis, gen. et sp. nov. (Eocene), Eogrigoriora gracilis, gen. et sp. nov. (Eocene), Miophlugis rostratus, gen. et sp. nov. (Miocene)], Stenopelmatidae [Siinae: Electrosia baltica, gen. et sp. nov. (Eocene); Gryllacridinae: Plesiolarnaca prior, gen. et sp. nov. (Eocene)] and Tridactylidae [Mongoloxyinae: Birmitoxya intermedia, gen. et sp. nov. (Upper Cretaceous). The Eocene species Lipotactes martynovi Zeun. and L. bispinatus Weidn. are transferred to the genus Eomortoniellus Zeun. (Tettigoniidae: Tympanophorinae); Prorhaphidophora zeuneri Chop. and P. tachycinoides Chop. are transferred to the genus Protroglophilus Gor. (Rhaphidophoridae: Protroglophilinae). The Eocene species E. handlirschi Zeun., species of the genus Protroglophilus, and a possible member of the genus Succinotettix Piton (Tetrigidae: Tetriginae), as well as a Miocene representative of the genus Archaeoellipes Heads (Tridactylidae: Tridactylinae) are also discussed.     

A new seabird (Aves, cf. Phaethontidae) from the Lower Eocene phosphates of Morocco

A proximal part of humerus from the basal Ypresian (lowermost Eocene) of the Ouled Abdoun Basin, Morocco, is described as a new genus and species tentatively assigned to the Phaethontidae (tropicbirds). This fossil possibly represents the oldest record of the Phaethontidae and markedly differs from Lithoptila, a contemporaneous Prophaethontidae from the same locality. This new taxon lived in a tropical climate and was probably an efficient flier with pelagic habits, like extant tropicbirds of the genus Phaethon.     

First fossil record of the genus Nageia (Podocarpaceae) in south China and its phytogeographic implications

The first fossil record of the genus Nageia Gaertner from the Tertiary of southern China is reported. Nageia hainanensis sp. nov. is described from the Eocene Changchang Formation of Hainan Island. The extant species of Nageia are widely distributed in southeastern Asia, from northeastern India to southeastern China and southern Japan, and southward through Indochina to the Malay Archipelago and New Guinea. The fossil evidence of Nageia has been discovered from the Lower Cretaceous of the Far East of Russia and Japan. The distribution of both modern and fossil species of Nageia indicates that this genus could have originated in the northeastern part of Asia in the Early Cretaceous and spread to south China at least in the Eocene. Discovery of Nageia fossil record in south China provides important evidence for the geological and phytogeographic history of the genus.     

New taxa of Mesorthopteridae (Insecta: Grylloblattida) from the Permian of Russia

New taxa of grylloblattids of the family Mesorthopteridae are described from the Permian of Russia: Parastenaropodites aquilonius sp. nov. from the Soyana locality (Middle Permian); P. circumhumatus sp. nov. from the Kul’chumovo locality; and Tshermyaninus biforis gen. et sp. nov., Permorthopteron foliaceus gen. et sp. nov., Parastenaropodites pannea sp. nov., P. exossis sp. nov., Mesoidelia procera sp. nov., and M. riphaea sp. nov. from the Isady locality (Upper Permian). Two species of the genus Khosaridelia Storozhenko, 1992 (family Permotermopsidae) and one species of the genus Megakhosarina Storozhenko, 1993 (family Megakhosaridae) are transferred to the genus Parastenaropodites Storozhenko, 1996 (family Mesorthopteridae); one species of the genus Parastenaropodites is transferred to the genus Austroidelia Riek, 1954; as a result, four new combinations are established: Khosaridelia rigida Aristov, 2005 =Parastenaropodites rigidus (Aristov, 2005), comb. nov. (Vorkuta locality, Lower Permian of Russia); Khosaridelia vyatica Aristov, 2009 =Parastenaropodites vyaticus (Aristov, 2009), comb. nov. (Karaungir locality, Middle Permian of Kazakhstan); Megakhosarina intricata Aristov, 2008 =Parastenaropodites intricatus (Aristov, 2008), comb. nov. (Soyana locality, Middle Permian of Russia); and Parastenaropodites nervosa Storozhenko, 1996 =Austroidelia nervosa (Storozhenko, 1996), comb. nov. (Madygen locality, Middle Triassic of Kyrgyzstan). An identification key to species of the genus Parastenaropodites is given.     

The first New World occurrence of the Eocene birdPlesiocathartes (Aves: ?Leptosomidae)

Two new species of the Eocene avian taxonPlesiocathartes (Aves: ?Leptosomidae) are described. They are similar in size and overall appearance to other members of the genus, as well as to the extant Madagascan cuckoo-rollerLeptosomus discolor. So far, putative fossil Leptosomidae have been found only in the Eocene European de-posits of Messel, Geiseltal, Quercy, and London Clay. Both new species are from the Lower Eocene Green River Formation (USA) and thus the first New World representatives of this taxon.     

New jewel beetles (Coleoptera: Buprestidae) from the Cretaceous of Russia,Kazakhstan, and Mongolia

A new jewel beetle genus, with one species (Cretofrontolina kzyldzharica gen. et sp. nov.) from the Upper Cretaceous of Kazakhstan is described based on a body; and three new species of the formal genus Metabuprestium are described based on isolated elytra: Metabuprestium sibiricum sp. nov. and M. arkagalense sp. nov. come from the Arkagala locality (Upper Cretaceous of Russia) and M. ichbogdense sp. nov. is from the Shar Tologoi locality (Lower Cretaceous of Mongolia).     

Deux nouvelles tortues de l'Éocène inférieur de Saint-Papoul (Aude, France)

Two new turtles from the Lower Eocene of Saint-Papoul (Aude, France). Among the fossil turtles from of the Lower Eocene of Saint-Papoul (Aude, France), two new taxa of freshwater Testudinoidea are described. The first is a new species of the genus Palaeoemys, known before in the Lutetian of Germany. The second taxon is a new genus, also described on material of Pépieux-Cesseras and Eygalayes. To cite this article: S. Hervet, C. R. Palevol 2 (2003).     

A new species and a new combination of the Mesozoic genus Podocarpophyllum Gomolitzky (Coniferales)

Podocarpophyllum Gomolitzky is studied in detail from the type locality Angren (Uzbekistan, Middle Jurassic). Emended diagnoses of the genus and its type species P. singulare Gomolitzky are provided. For the first time, members of the genus are reported from the Lower Jurassic of the Mangyshlak Peninsula (western Kazakhstan), where P. kazachstanicum sp. nov. is described, and from the Middle Jurassic of the eastern Ural Mountains, where P. mesozoicum (Kiritchkova) comb. nov. is established. The epidermal morphology of the genus Podocarpophyllum is compared with that of fossil and modern members of the Podocarpaceae.     

New grylloblattids of the family Lemmatophoridae (Insecta: Grylloblattida) from the Permian of Russia

New grylloblattids of the family Lemmatophoridae (Insecta: Grylloblattida), Artinska sojanensis sp. nov., Sylvaprisca colorata sp. nov., and Uraloprisca lisca gen. et sp. nov., from the Soyana locality (Lower Kazanian, Arkhangelsk Region) and Paraprisca solikamskensis sp. nov. from the Tyul’kino locality (Ufimian, Perm Region) are described. Two species are transferred from the genus Paraprisca to Uraloprisca gen. nov.: Uraloprisca uralica (G. Zalessky, 1952), comb. nov. and Uraloprisca causaria (Novokshonov, 2000), comb. nov. (both from the Kungurian of the Perm Region). The evolution of the family is discussed.     

Taxonomy of the fossil grylloblattid nymphs (Insecta: Grylloblattida)

Nymphs of fossil grylloblattid insects are revised. Newly described taxa are Lemmatonympha gracilissima gen. et sp. nov. and Kaltanympha vorcutensis sp. nov. from the Verkhne-Syr’yaginsk locality (Ufimian, Lek-Vorkuta Formation in the Vorkuta Coal Basin), genera Sylvalitoralis gen. nov. and Tshebardanympha gen. nov. from the Tshekarda locality (Kungurian, Koshelevka Formation, Middle Urals), Tataronymphakamensis gen. et sp. nov. from the Tikhie Gory locality (Lower Kazanian, linguloid beds of the Baitugan Formation, Tatarstan), and Kaltanympha ornata sp. nov. from the Kerbo locality (Upper Tatarian, lower part of the Degali Formation, Evenki Autonomous Region). Liomopterites (?) gracilis Sharov, 1961 from Lower Kazanian deposits of the Kuznetsk Formation in the Kuznetsk Basin is transferred to the genus Kaltanympha Sharov, 1961; Permonympha arcuata Sharov, 1957 from the same locality is synonymized under Permonympha gracile Sharov, 1957; the nymph described from the Karatau locality (Upper Jurassic, Karabastau Formation in southern Kazakhstan) as Blattogryllus karatavicus Rasnitsyn, 1976 is excluded from grylloblattids. Keys to extinct grylloblattid nymphs are provided.     

New Triassic beetles (Coleoptera) from northern European Russia

Beetle remains from the Triassic Khey-Yaga locality, Nenets National District, Korotaikha Basin, Nyadeita Formation, Olenekian-Anisian are described. Only isolated elytra have been found. Tetracoleus tshalyshevi gen. et sp. nov. and T. minimus sp. nov. are described and assigned to Tricoleidae, and six new species are described in formal taxa. Tetracoleus is close to Permian tricoleids just found in the Newcastle Group of Australia and the Vyatkian Aristovo locality of northern European Russia. The composition of elytra in the locality is closer to that of Lower Triassic localities than other Middle Triassic localities and characterizes the beginning of a recovery after the Permian-Triassic ecological crisis. Longxianocupes Hong in Liu, Liu et Hong, 1985 is shown to be a junior synonym of Sogdelytron Ponomarenko, 1969. The species Palademosyne ovum Ponomarenko, 2004, P. elongatum Ponomarenko, 2004, and P. latum Ponomarenko, 2004 are transferred to the genus Pseudochrysomelites Handlirsch, 1906.     

The “miacids” (Carnivoraformes,Mammalia) from the Early Eocene locality of Le Quesnoy (MP7, France); first occurrence of Vassacyon in Europe

We describe here “miacid” taxa from the Early Eocene Paris Basin locality of Le Quesnoy (Oise, France). We describe the new species Vassacyon taxidiotis, the first European record of this genus. The other “miacids” identified from Le Quesnoy are Miacis latouri and Gracilocyon solei. The P4 of G. solei is described here for the first time. Its morphology (e.g., wide protocone, short postmetacrista) supports a close relationship with Miacis rundlei from Abbey Wood (MP8 + 9, England). The latter species is therefore classified as Gracilocyon rundlei. Three new tooth positions are known for Miacis latouri: P4, p4 and m2. They support its reference to Miacis. These specimens imply that the European species is more basal than the North American species. The fauna from Le Quesnoy shares with Dormaal the presence of Miacis latouri and Gracilocyon solei, but the “miacid” fauna from Le Quesnoy also contains Vassacyon taxidiotis. The presence in Le Quesnoy of the two former taxa supports a reference to MP7 level of the French locality. The presence of three distinct genera in European localities show that the “Miacidae” were diversified in Europe, as previously observed in North America. The genera Gracilocyon, Miacis, and Vassacyon probably dispersed from Europe to North America during the Palaeocene/Eocene boundary.     

The first record of dicosmoecinae from the Cenozoic of the Russian Far East with a brief global overview of fossil Limnephilidae (Insecta: Trichoptera)

A new genus and species, Prodicos rasnitsyni gen. et sp. nov. (Trichoptera, Limnephilidae), from the Upper Eocene–Lower Oligocene of Russia is described. The global fossil record of adult Limnephilidae is reviewed.     

New species of the genus Acar (Bivalvia) from the Eocene of Ukraine

New bivalve species of the genus Acar from the Upper Eocene of Dnepropetrovsk (Ukraine) are described. The differences in ontogenetic development of these species from the close genus Barbatia are discussed.     

Presence of Zanthopsis M’Coy, 1849 (Crustacea: Decapoda: Brachyura) in the Early Eocene of Iran,and comments on the different species and/or morphotypes and their palaeobiogeography

In the present work, we report the discovery of several carapaces of Zanthopsis sp. from the Lower Eocene of Central Iran, which represent the easternmost record of the genus. In addition, we discuss on the similarities of the different species and/or morphotypes of the genus, and conclude that the European species could be ascribed to the “Zanthopsis leachii complex”, until future works determine the validity of the species therein contained. In this sense, Zanthopsis jacobi Van Straelen, 1924, in agreement with Artal and Vía (1988), is herein considered a junior synonymous of Z. dufouri (H. Milne Edwards in d’Archiac, 1850). The presence of Zanthopsis in the lower Eocene of Iran suggests homogeneity of the brachyuran fauna on both sides of the Tethys Realm.     

On the mesozoic taxa of scarabaeoid beetles of the family Hybosoridae (Coleoptera: Scarabaeoidea)

Three new species of scarabaeoid beetles of the family Hybosoridae are described in the new genus Protohybosorus, gen. nov. from the Middle-Upper Jurassic of Kazakhstan (Karatau-Mikhailovka locality). The Lower Cretaceous species Geotrupoides fortus Ren, Zhu et Lu, 1995 (Inner Mongolia, China) is transferred to the genus Leptosorus Nikolajev, 2006.     

A new genus of the subfamily Anaidinae (Coleoptera, Scarabaeoidea, Hybosoridae) from the Mesozoic of Transbaikalia

A new genus and species, Protanaides sibiricus gen et sp. nov., of the subfamily Anaidinae (family Hybosoridae) from the Lower Cretaceous Baisa locality in Transbaikalia is described. This find adds considerably to knowledge of the diversity of this subfamily in the Mesozoic of Asia and gives evidence of the relict status of the Recent Anaidinae.
