中生代线蛉科化石(昆虫纲,脉翅目)

线蛉科是脉翅目中的一个灭绝科,仅发现于中国中侏罗统和蒙古晚侏罗统地层中。线蛉科昆虫脉序独特,为其分类地位的确定以及整个脉翅目翅脉演化的研究提供了重要的线索;此外,线蛉科昆虫前后翅上均具有条带状的斑纹,初步推测这种斑纹在其生存繁衍过程中发挥了积极作用,也可能是导致其灭绝的最直接因素之一。目前线蛉科已发表3属9种,本文对其进行了简要的回顾,并编制了线蛉科化石种检索表,对当时的古环境特征进行了简单推测,初步探讨了翅斑在其生存和灭绝中的作用。     

NEW FOSSIL LACEWINGS AND ANTLIONS (INSECTA, NEUROPTERA) FROM THE LOWER CRETACEOUS CRATO FORMATION OF BRAZIL

Abstract:  Remarkable new fossil taxa of Neuroptera from the laminated limestone of the Crato Formation, north-east Brazil, are described: Nuddsia longiantennata gen. et sp. nov. (Osmylidae, Gumillinae), the first fossil record of this family from South America, Parapalaeoleon magnus gen. et sp. nov. (Palaeoleontidae), and Triangulochrysopa formosa sp. nov. (Mesochrysopidae). A diagnosis of Gumillinae is provided; Epiosmylidae is considered to be a synonym of this subfamily. A revised diagnosis of Palaeoleontidae is provided, based on a new interpretation of venational characters evident on the exceptionally well-preserved specimen of P. magnus ; vein homologies are determined and the fusion of MP and CuA is discussed. The genus Triangulochrysopa has been known previously only from the Lower Cretaceous of Las Hoyas, Spain.

仙女蝎蛉科的最古老化石(昆虫纲,长翅目)在中国陕西首次发现

AN EXCEPTIONALLY PRESERVED ANTLION (INSECTA, NEUROPTERA) WITH COLOUR PATTERN PRESERVATION FROM THE CRETACEOUS OF BRAZIL

Abstract:  A new species of palaeoleontid neuropteran Baisopardus cryptohymen sp. nov. is described. The holotype is remarkable for the preservation of fine body structures and colour patterning on all of its four wings. The specimen is nearly complete, lacking only the abdomen and the right mesothoracic leg, and is preserved as a black-brown compression in laminated limestone of the Nova Olinda Member, Crato Formation (late Aptian, Early Cretaceous), Ceará, Brazil. The colour pattern of the forewings comprises a series of dark brown bands that overlap with colourless bands of the hindwings; it produced a cryptic colour pattern when the wings were folded.     

旗腹蜂总科化石研究进展

A NEW FOSSIL HOVERFLY (INSECTA, DIPTERA: SYRPHIDAE) FROM THE RANDECK MAAR (EARLY MIOCENE, SOUTH-WEST GERMANY)

Abstract:  Helophilus nothobombus sp. nov. (Diptera: Syrphidae) is described from Early Miocene lake sediments of the Randeck Maar (Swabian Alb, south-west Germany) and compared to other fossil species of the genus. Helophilus primarius Germar, 1837 and Helophilus villeneuvi Théobald, 1937 do not show diagnostic features that allow assignment to the genus Helophilus or even to the tribe Eristalini. Helophilus miocaenicus (Stackelberg, 1925) and H. nothobombus thus are the only plausible fossil species of the genus. The rat-tailed maggots of Helophilus most probably were part of the biocoenosis of the shores of the Randeck Maar lake. The frequency of larvae of Stratiomyidae shows that there were also suitable habitats for species of Helophilus and related genera.

GOING FURTHER INTO LATE MESOZOIC MESOLYGAEIDS (HETEROPTERA, INSECTA)

A large collection of fossil insects has recently been recovered from the Late Mesozoic nonmarine sediments throughout East Asia, with many specimens regarded as the mesolygaeids, representing a new family Mesolygaeidae of Heteroptera. As Lycoptera Muller and Eosestheria Chen, Mesolygaeus Ping is the common genus of the Jehol fauna Since some of them are geographically widespread and can be easily collected, they are significant to stratigraphic divisions and correlations in East Asia.
