Abstract
A new subfamily of Scarabaeidae, †Electrorubesopsinae Bai & Wang subfam. nov., is described from Cretaceous amber of Myanmar (earliest Cenomanian, ∼100 Ma) as the possible sister group of Dynamopodinae. †Electrorubesopsis beuteli Bai & Wang gen. et sp. nov. is the first species of this subfamily, which has probably been long extinct. Its external morphology was analysed and compared with all known genera of Dynamopodinae. A phylogenetic analysis based on 82 morphological characters suggests its placement in a sister relationship between †Electrorubesopsis and Orubesa. The hypothesis of a close relationship between Orubesa (Dynamopodini) and Thinorycter (Thinorycterini) is challenged. †Electrorubesopsis likely lived in a sandy environment or forest.http://zoobank.org/urn:lsid:zoobank.org:pub:15351B5E-337C-49D4-90F0-619269BD1E5A

Abstract Burmese amber has recently provided some detailed glimpses of plumage, soft tissues, and osteology of juvenile enantiornithine birds, but these insights have been restricted to isolated wing apices. Here we describe nearly half of a hatchling individual, based on osteological and soft tissue data obtained from the skull, neck, feet, and wing, and identified as a member of the extinct avian clade Enantiornithes. Preserved soft tissue provides the unique opportunity to observe the externa...

Abstract A new cerambycid beetle ( Qitianniu zhihaoi gen. et. sp. nov.) is described on the basis of a single specimen embedded in Cretaceous Burmese amber (ca. 99 Ma). Unusual characteristics are hairy antennae and large lateral eyes, a pronotum with lateral margin, and sinuate protibiae. Based on a phylogenetic analysis, the systematic position of Qitianniu is still uncertain and we provisionally place it as Cerambycidae incertae sedis .

Abstract The Mastigitae is a small supertribe of ant-like stone beetles that currently includes nine extant and five extinct genera. Extinct taxa are known within tribes Clidicini and Mastigini; the latter with one genus discovered in Baltic amber. For the first time, a Mesozoic genus of the tribe Mastigini is described, Clidicostigus arachnipes Jaloszynski, Brunke and Bai, gen. et sp. nov., from Cenomanian Burmese amber. The new taxon shares an enlarged and spiny scape and pedicel with its exta...

The first fossil Athyreini in the subfamily of Bolboceratinae from the family of Geotrupidae, †Amberathyreus beuteli Bai et Zhang gen. et sp. nov., is described based on a specimen from the mid-Cretaceous Myanmar (Burmese) amber from northern Myanmar. Its external morphology (including 3D reconstruction of the head and pronotum) was analyzed and compared with all known genera of Athyreini. †Amberathyreus’ close relationship between Athyreini and Bolboceratini is supported. †Amberathyreus was lik...

Summary In the two decades since the discovery of feathered dinosaurs [1–3], the range of plumage known from non-avialan theropods has expanded significantly, confirming several features predicted by developmentally informed models of feather evolution [4–10]. However, three-dimensional feather morphology and evolutionary patterns remain difficult to interpret, due to compression in sedimentary rocks [9, 11]. Recent discoveries in Cretaceous amber from Canada, France, Japan, Lebanon, Myanmar, an...

Abstract A new insect species (†Alienopterus brachyelytrus Bai, Beutel, Klass, Wipfler et Zhang gen.etsp. nov.) of a new order and family is described, based on a single male embedded in Cretaceous Burmese amber (ca. 99 Ma). Unusual characters are shortened forewings combined with fully developed, operational hindwings, similar as in Dermaptera, and specialized attachment pads otherwise only found in mantophasmatodeans (heelwalkers). A cladistic analysis suggests a placement as sister to Mantode...

Summary The anomalous occurrence of supposedly Gondwanan taxa in Laurasian-derived regions remains an intriguing chapter of paleobiogeographical history. Representatives of Peripatidae, a major subgroup of velvet worms (Onychophora), show a disjointed distribution in the neotropics, tropical Africa, and Southeast Asia, the latter being the only landmass previously associated with Laurasia [1, 2]. The arrival of these animals in Southeast Asia is explained by two alternative, albeit not mutually ...

Abstract A new family of Scarabaeoidea is revealed from the Cretaceous amber of Myanmar (earliest Cenomanian, near 100 Ma), on a series of males and females, most in perfect condition. Passalopalpidae fam. nov., Passalopalpus cheni gen. et sp. nov., are probably extinct since a long time. Observations were made on the whole body (head, thorax, abdomen) and appendages (mouthparts, antennae, legs, wings). Most characters are remarkable and plesiomorphic, compared to Passalidae Leach, as well as to...

Our knowledge of Cretaceous plumage is limited by the fossil record itself: compression fossils surrounding skeletons lack the finest morphological details and seldom preserve visible traces of colour, while discoveries in amber have been disassociated from their source animals. Here we report the osteology, plumage and pterylosis of two exceptionally preserved theropod wings from Burmese amber, with vestiges of soft tissues. The extremely small size and osteological development of the wings, co...

Abstract Two new species, Cretohypna puncta sp. nov. and Cretohypna robusta sp. nov., of Glaphyridae are described and illustrated. These fossils were collected from the Jehol Biota, Lower Cretaceous Yixian Formation of Liutiaogou Village in Ningcheng, Inner Mongolia, China. Up to date, 18 fossil species in 6 genera of Glaphyridae have been reported, among which ten species are from China. Respective keys to the Mesozoic genera of Glaphyridae and to species of Cretohypna Yan, Nikolajev & Ren, 20...
