A new subfamily of ichneumon wasps, Labenopimplinae subfam. nov. (Ichneumonidae), is described from the Cenomanian Ola Formation of the locality Obeshchayushchiy, Magadan Region, Russian Far East. The subfamily is highly diverse morphologically and combines characters of the Labeninae and Pimplinae. It includes 11 new species described in five new genera: Labenopimpla rasnitsyni gen. et sp. nov., L. kasparyani sp. nov., Armanopimpla zherikhini gen. et sp. nov, Ramulimonstrum intermedium gen. et sp. nov., Rugopimpla vulgaris gen. et sp. nov., R. fallax sp. nov., R. angusticella sp. nov., R. macra sp. nov., R. matrona sp. nov., Micropimpla lucida gen. et sp. nov., and M. obscura sp. nov. Also described is a new monotypic genus, Tryphopimpla xoridoptera gen. et sp. nov., which combines characters of the Tryphoninae, Pimplinae, and Xoridinae and cannot be currently placed into any of the known subfamilies. The population of fossil ichneumon wasps at this locality is distinctly dominated by females.  相似文献

A new genus and species of heterotrophic dinoflagellate, Cryptoperidiniopsis brodyi gen. et sp. nov., are described. This new species commonly occurs in estuaries from Florida to Maryland, and is often associated with Pfiesteria piscicida Steidinger et Burkholder, Pseudopfiesteria shumwayae (Glasgow et Burkholder) Litaker et al., and Karlodinium veneficum (Ballantine) J. Larsen, as well as other small (<20 μm) heterotrophic and mixotrophic dinoflagellates. C. brodyi gen. et sp. nov. feeds myzocytotically on pigmented microalgae and other microorganisms. The genus and species have the enhanced Kofoidian plate formula of Po, cp, X, 5′, 0a, 6″, 6c, PC, 5+s, 5″′, 0p, and 2″″ and are assigned to the order Peridiniales and the family Pfiesteriaceae. Because the Pfiesteriaceae comprise small species and are difficult to differentiate by light microscopy, C. brodyi gen. et sp. nov. can be easily misidentified.  相似文献

One new genus and four new species of ichneumon wasps are described from the Lower Cretaceous of Buryatia (Khasurty locality): Amplicella mininae, sp. nov., A. shcherbakovi, sp. nov., A. bashkuyevi, sp. nov., Khasurtella buriatica, gen. et sp. nov. The species Tanychora sinensis Zhang, 1991 is transferred to the new genus Khasurtella. Similarity of the ichneumonid faunas of Khasurty and the Chinese localities Yixian and Laiyang indicates the age similarity between these localities. Identification key to genera and species of Tanychorinae is given.  相似文献

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora. An emended diagnosis of the genus Ascoporella Krutchinina, 1986, is provided. This genus comprises nine species, of which two, A. lecta sp. nov. and A. mera sp. nov., are described as new species.  相似文献

The problematic lizard family Changjiangosauridae, representatives of which inhabited Asia in the Early Paleogene, is discussed. Six new species of this group, including Acrodontopsis robustus gen. et sp. nov., Agamimus gracilis gen. et sp. nov., Graminisaurus interruptus gen. et sp. nov., Khaichinsaurus reshetovi gen. et sp. nov., Lavatisaurus elegans gen. et sp. nov., and Lentisaurus giganteus gen. et sp. nov., from the Middle Eocene of the Khaichin Uul 2 locality (southern Gobi, Mongolia) are described. It is shown that Changjiangosauridae are probably related to the Late Cretaceous Isodontosauridae and recent Uromastycidae; independent development of a number of dental features in different lineages of Acrodonta (Iguania) is corroborated.  相似文献

Abstract: Acid preparation of samples of a bonebed from the Cenomanian of central Canada yielded several thousand well‐preserved chondrichthyan teeth, in addition to numerous other vertebrate remains. Teeth and other remains of one species of chimaeroid, one species of hybodont shark, three species of Ptychodus, 10 species of neoselachian sharks and two species of batoid were recorded. The family Archaeolamnidae fam. nov., genera Meristodonoides gen. nov. and Telodontaspis gen. nov. and species Ptychodus rhombodus sp. nov., Telodontaspis agassizensis gen et sp. nov., Eostriatolamia paucicorrugata sp. nov., Roulletia canadensis sp. nov., Cretorectolobus robustus sp. nov. and Orectoloboides angulatus sp. nov. are described. Status of the genus Palaeoanacorax and the species Cretoxyrhina denticulata, Squalicorax curvatus and ‘Rhinobatosincertus are discussed, and reconstructed dentitions of Archaeolamna and Roulletia presented. The fauna is of low diversity and dominated by active hunters, with many species apparently endemic to the northern Western Interior Seaway.  相似文献

Seven new species of Paramunnidae from the Magellan Strait are described, two of which are placed in new genera: Paramunna magellanensis sp. nov., P. menziesi sp. nov., P. parasimplex sp. nov., P. patagoniensis sp. nov., Allorostrata ovalis gen. et sp. nov., Austrosignum dentatum sp. nov., and Magellianira serrata gen. et. sp. nov. Four known paramunnid species from the same location are redescribed: Parammunna integra, P. simplex, P. subtriangulata and Munnogonium tillerae . While investigating the genus Paramunna , two species of this group, Acutomunna foliacea (Chardy, 1975) gen. nov. and Paramunna foresti Carvacho , 1977 were removed, which involved the erection of a new genus. The allocation of P. foresti remains uncertain. Some diagnostic characters of the Paramunnidae and a key to the Magellanic species of Paramunna are presented.  相似文献

A new fossil genus and species of oribatid mite, Cretaceobodes martinezae gen. et sp. nov., belonging to the family Otocepheidae is described. The new species is preserved in a piece of amber from the San Just outcrop (Teruel Province, Spain), which is believed to be Albian in age. The new genus is compared with the extant genus Carabocepheus Berlese, 1910 and its relationships with the superfamilies Otocepheoidea and Carabodoidea are discussed. Carabocepheidae is regarded as a junior synonym of Otocepheidae. Ranking Carabocepheus lounsbury latior Balogh et Mahunka, 1966 as a separate species is proposed.  相似文献

Abstract:  Three new genera and four new species of the extinct mantidfly subfamily Mesomantispinae (Insecta: Neuroptera: Mantispidae) are described from the Lower Cretaceous Yixian Formation of Liaoning and the Middle Jurassic Jiulongshan Formation of Inner Mongolia: Archaeodrepanicus nuddsi gen. et sp. nov., A. acutus gen. et sp. nov., Sinomesomantispa microdentata gen. et sp. nov., (Yixian Formation) and Clavifemora rotundata gen. et sp. nov. (Jiulongshan Formation). The specimens described herein represent the first Mesozoic mantidfly compression fossils to have body parts preserved, including the specialized raptorial forelegs articulated to the prothorax anteriorly, an autapomorphy of the family. These new taxa further confirm the placement of the subfamily Mesomantispinae within the family Mantispidae; however, the monophyly of Mesomantispinae has not been confirmed, and it is likely that it will prove to be paraphyletic.  相似文献

In this paper, five new pollen genera and twenty new pollen species of angiospermae from the Late Cretaceous of a certain basin in central China are described. Four new organ genera and their species include: Morinoipollenites normalis gen. et sp. nov., Morinoipollenites minor gen. et sp. nov., Morinoipollenites polyprojectus gen. et sp. nov., Morinoipollenites rhombiformis gen. et sp. nov., Jianghanpollis ringens gen. et sp. nov., Jianghanpollis, mikros gen. et sp. nov., Jianghanpollis radiatus gen. et sp. nov., Jianghanpollis sayangensis gen. et sp. nov., Jianghanpollis arciformis gen. et sp. nov., Myoporumpollonites variabilis gen. et sp. nov., Myoporumpollenites striatus gen. et sp. nov., Lythraites giganteus Yu, Guo et Mao gen. et sp. nov. Lythraites clavatus sp. nov., Lythraites dilutus sp. nov., Lythraites magnus sp. nov., Lythraites varrustriatus sp. nov., Lythraites pachyrrhachis sp. nov.; the new-form genus and its species are: Crassimarginpollenites reticulatus gen. et sp. nov., Crassimerginpollenites mirus gen. et sp. nov., Crassimarginpollenites psilatus gen. et sp. nov. The new pollen genera and their species described herein have been compared in some details with recent pollens and considered their affinity with such recent families as Dipsacaceae, Myoporaceae, Apocynaceae and Lythraceae. According to the age of the pollen-bearing strata, a preliminary discussion is made regarding to the taxonomy of the recent plants families with which our new described pollens are related. Hence, this study may provide some mieropalaeobotanical information for deciphering 'the phylogeny of these plants.  相似文献
