Fossil history of Mesozoic weevils (Coleoptera: Curculionoidea)

Abstract The first synopsis of Mesozoic weevils (Curculionoidea: Coleoptera) is presented. Changes of family, genera and species abundance during the Mesozoic revealed three distributional patterns. The Jurassic (Karatau) fauna was dominated by the Nemonychidae. During the Early Cretaceous (beginning at the Jurassic/Cretaceous border), the Ithyceridae was the prevalent group with a significant role played by the Nemonychidae. In the Late Cretaceous (Cenomanian and Turonian), the major groups were the Curculionidae and Brentidae. Obviously, the change of weevil fauna during this period was due to the expansion of the angiosperms, which provided multiple niches in their vegetative and reproductive organs for weevil development.     

A NEW LATE CRETACEOUS MACROSEMIID FISH (NEOPTERYGII, HALECOSTOMI) FROM MOROCCO, WITH TEMPORAL AND GEOGRAPHICAL RANGE EXTENSIONS FOR THE FAMILY

Abstract:  A recent collection of actinopterygian fossil fishes from a previously unreported locality in the Cenomanian or Turonian of southeastern Morocco includes a single specimen of a macrosemiid fish. Macrosemiids are more common in Jurassic and Early Cretaceous deposits, with the previously known range of the family being Late Triassic through Aptian or Albian. This discovery therefore extends the temporal range of the family into the Late Cretaceous. Moreover, macrosemiids had not previously been reported from northern Africa or the Moroccan area of the Tethys basin; therefore, this fossil also increases the geographical range of the family. The Moroccan macrosemiid is described in a new genus and species, Agoultichthys chattertoni . A phylogenetic analysis places it basal to all other genera of the family with the exception of Notagogus . Diagnostic characters of the new species include the high number of scales laterally along the body and the greater number of dorsal fin rays than in other members of the family.     

Diversity variation and tempo-spatial distributions of the Dipteridaceae ferns in the Mesozoic of China

The extant family Dipteridaceae is a remarkable leptosporangiate fern because it includes only one genus with a restricted distribution to tropical regions. The fossil record of this family has been widely reported from the Mesozoic strata in Eurasia, America, Australia, and Greenland. In China, numerous fossils of the Dipteridaceae have been documented, in total, about 74 species of 6 genera. Geographically, they are distributed both in the Southern and Northern Floristic Provinces, and were particularly well developed in the Southern Floristic Province during the Late Triassic and the Early Jurassic intervals. Fossil diversity of Dipteridaceae varies in the different episodes of the Mesozoic in China. It is shown that Dipteridaceae has undergone a diversity development process and a distinct turnover during the Mesozoic. They appear to have diversified in the warm and humid Late Triassic–Early Jurassic, but declined sharply as aridity developed in the Middle Jurassic, and became extinct at the end of the Early Cretaceous. The diversity variation and tempo-spatial distribution pattern is suggested to be linked with paleoclimatic variations during the Mesozoic.     

Mesozoic conifers

The Coniferophyta attained their greatest diversity and abundance during the Mesozoic Era. Many early forms died out without apparent involvement in the evolution of the modern types. Yet, all living coniferophyte families and a surprising number of their present-day genera are clearly in evidence in the Mesozoic. Generally, modern families are recognizable by the Late Triassic or Early Jurassic while certain contemporary genera make their appearance as early as the Middle Jurassic. The Pinaceae appears to lag behind other families in that it lacks unequivocal representation before the onset of the Cretaceous although certain Late Triassic and Jurassic remains may belong to the family. Modern coniferophyte families appear to have originated somewhat earlier than was formerly believed and this brings to light problems in envisioning their evolution from the known Voltziales. Seed cones of certain of the latter are now known from petrified material which show a greater modification than was formerly known. Various kinds of detached organs that cannot be assigned to existing families are described and discussed and the bearing of the fossil record in certain questions on coniferophyte systematics is evaluated.     

Evolution of Lycopodiaceae (Lycopsida): estimating divergence times from rbcL gene sequences by use of nonparametric rate smoothing

By use of nonparametric rate smoothing and nucleotide sequences of the rbcL gene, divergence times in Lycopodiaceae are estimated. The results show that much extant species diversity in Lycopodiaceae stems from relatively recent cladogenic events. These results corroborate previous ideas based on paleobotanical and biogeographical data. Previous molecular phylogenetic analyses recognized a split into neotropical and paleotropical clades in Huperzia, which contains 85-90% of all living species. Connecting this biogeographical pattern with continent movements, the diversification of this epiphytic group was suggested to coincide with that of angiosperms in the mid to Late Cretaceous. Results presented here are consistent with this idea, and the diversification of the two clades is resolved as Late Cretacous (78 and 95 Myr). In the related genera Lycopodium and Lycopodiella, the patterns are somewhat different. Here species diversity is scattered among different subgeneric groups. Most of the high-diversity subgeneric groups seem to have diversified very recently (Late Tertiary), whereas the cladogenic events leading to these groups are much older (Early to Late Cretaceous). Our analysis shows that, although much living species diversity stems from relatively recent cladogenesis, the origins of the family (Early Carboniferous) and generic crown groups (Early Permian to Early Jurassic) are much more ancient events.     

Phase contrast X‐ray synchrotron microtomography and the oldest damselflies in amber (Odonata: Zygoptera: Hemiphlebiidae)

Electrohemiphlebia barucheli gen. et sp. nov. and Jordanhemiphlebia electronica gen. et sp. nov. , two new genera and species are described, based on exceptional inclusions of hemiphlebiid damselflies in Cretaceous amber from France and Jordan. The type specimen of E. barucheli was studied using phase contrast X‐ray synchrotron microtomography, giving exceptional images and detailed information. Its comparison with the recent Hemiphlebia mirabilis confirms the attribution of several Cretaceous damselflies to the Hemiphlebiidae, showing that this particular group was widespread in the Early Cretaceous and probably originated in the Late Jurassic or earlier. The ecological niches today occupied by the small coenagrionoid damselflies were occupied during the Triassic and Jurassic by Protozygoptera, hemiphlebiids during the Early Cretaceous, and modern taxa in the Cenozoic.     

A well-preserved aneuretopsychid from the Jehol Biota of China (Insecta, Mecoptera, Aneuretopsychidae)

The Aneuretopsychidae is an unspeciose and enigmatic family of long-proboscid insects that presently consist of one known genus and three species from the Late Jurassic to Early Cretaceous of north-central Asia. In this paper, a new genus and species of fossil aneuretopsychid is described and illustrated, Jeholopsyche liaoningensisgen. et sp. n. Fossils representing this new taxon were collected from mid Early Cretaceous strata of the well known Jehol Biota in Liaoning Province, China. This finding documents the first formal record of fossil Aneuretopsychidae in China. In addition, this well-preserved and new material reveals previously unknown and detailed morphological structure of the mouthparts, antennae, head, thorax, legs and abdomen of this distinctive insect lineage.

Phylogeny of Stephanidae (Hymenoptera: Apocrita) with a new genus from Upper Cretaceous Myanmar amber

A new wasp species, Lagenostephanus lii Li, Rasnitsyn, Shih and Ren gen. et sp.n. , is assigned to Stephaninae (Hymenoptera: Stephanidae). The specimen is described from the lowermost Upper Cretaceous Myanmar (Burmese) amber. This is the second stephanid wasp described from Myanmar amber after Kronostephanus zigrasi Engel & Grimaldi, representing the earliest fossil occurrences of Stephanidae. Based on morphological characters of all extant and extinct genera, a phylogenetic analysis of Stephanidae was conducted. The results indicate that Schlettereriinae and Stephaninae are monophyletic, whereas Electrostephanus Brues, as the only genus within Electrostephaninae, belongs to Stephaninae. Therefore, we propose a synonymy of Electrostephaninae with Stephaninae. Based on the fossil evidence, we infer that the family of Stephanidae was significantly diverse in the Late Cretaceous and that they originated during the Early Cretaceous or late Jurassic. A key to genera of Stephanidae is provided. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:C082C245-8FD3-42B0-880F-94333286500B .
