Abstract
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 extant relatives but has deep elytral grooves and a strongly elongate and asymmetrical maxillary palpomere IV; the beetle has also enormously elongate maxillary palps and legs. The elongation of appendages in combination with only moderately large eyes is postulated to have evolved as an adaptation to running quickly, with tactile and chemical senses predominating over sight. The mode of life of Clidicostigus might have been similar to that of extant Mastigini, especially of particularly slender South African species that run on the ground and climb bushes and trees in search of prey.

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. et sp. 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 Man...

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...

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...

Abstract A new genus and species of the ant-like stone beetle supertribe Mastigitae, Cretoleptochromus archaicus gen. et sp. nov., is described and figured based on an exceptionally well-preserved individual in the Upper Cretaceous (lowermost Cenomanian, ca. 99 Ma) amber from Myanmar. Cretoleptochromus is undoubtedly placed in Mastigitae based on its distinctly geniculate antennae with strongly elongate antennal scape, and pointed labial palpomere III. Cretoleptochromus is most likely the sister...

The Hybosoridae is a cosmopolitan family of Scarabaeoidea that is most diverse in the tropics. Up to now, all published Mesozoic hybosorids were compression fossils, except for one from Lebanon amber which is incomplete. A new species, Hybosorus ocampoi Bai et Zhang sp. nov., of Hybosoridae (Scarabaeoidea) is described and illustrated based on one well-preserved Myanmar amber specimen. The phylogenetic position of H. ocampoi was analyzed by employing 117 morphological characters and 44 extant/ex...

A wingless and eyeless tiny fossil embedded in Cretaceous amber from Myanmar is described and interpreted phylogenetically as beetle larva, very likely belonging to a cucujiform group of Coleoptera with parasitic habits, probably the family Ripiphoridae. Features supporting this are the lobe-like terminal elements of the legs and the pattern of setae on the abdomen. However the larva display specialized features differing from immatures of extant ripiphorid species, such as for instance the abse...

Abstract Eucinetidae is a small beetle family comprising only ten extant genera. Five of them have unusually modified mouthparts with a strongly transformed labium, which shows features interpreted as adaptations to suctorial feeding. Among the hyperdiverse Coleoptera, similar feeding adaptations are known only in several genera of Cerylonidae and Leiodidae. Fossils attributed to Eucinetidae or representing taxa presumably closely related to eucinetids are known from Lower Cretaceous of China an...

Abstract The Glandulariini includes 71 genera comprising over 70% of the extant nominal species of Scydmaeninae. Extant members of this tribe are ubiquitous in forests of all continents. Because of small size of most species (often below 2 mm), taxonomic problems accumulated over the past 200 years, and scarcity of fossils with exposed ventral structures that are crucial for generic diagnoses, Glandulariini are rarely subjects of palaeontological studies. Consequently, only five Cretaceous gener...

The ant-like stone beetle tribe Glandulariini harbours approximately 3700 species, representing more than 70% of the extant diversity of the subfamily Scydmaeninae. Fossil records of this large tribe are rare, and are mostly confined to Eocene to Miocene amber, whereas only four genera were known from Mesozoic deposits. Here we report a new Mesozoic taxon, Pangusyndicus excavatus Yin, Zhou & Cai gen. et sp. nov., from Cenomanian Burmese amber. For the first time the ventral cephalic structures o...

The ant-like stone beetle supertribe Mastigitae (Staphylinidae: Scydmaeninae) comprises nine extant and five extinct genera that exhibit unusual morphological specializations and ecological adaptions. Recent discoveries of mastigite fossils from Upper Cretaceous–middle Eocene deposits have significantly improved our knowledge of the evolutionary history of this group, yet a direct fossil record for two modern tribes of unclear affinities, i.e. Leptomastacini and Papusini, is lacking. Herein we d...

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 ...

ABSTRACTThe exceptionally well-preserved and diverse insect fossil record of the Baltic amber group is a unique source for science. However, bubbles and thick layers of white gaseous froth cover numerous inclusions in this type of amber, rendering their examination with traditional light microscopy impossible. Here, we show that X-ray micro-computed tomography can be an efficient tool in such cases. We scanned a completely covered rove beetle (Staphylinidae) fossil in a piece of the relatively r...

Abstract The extinct ant-like stone beetle genus Cascomastigus Yin & Cai was recently established to accommodate C . monstrabilis Yin & Cai from the mid-Cretaceous Burmese amber. This species developed a highly specialized antennal ‘setal trap’, and was hypothesized to enroll these into predation on fast-moving preys, particularly springtails. However, only a single species of Cascomastigus has been known so far, and the paleodiversity of this peculiar group remains underexplored. Here we descri...

The tribe Scydmaenini represents one of the most successful modern groups of the ant-like stone beetles (Scydmaeninae), displaying a high degree of species diversity (>750 species) and morphological disparity. Surprisingly, direct fossil evidence crucial for elucidating the origin and early evolution of Scydmaenini is lacking. This gap of knowledge is of particular interest as the Cretaceous origin of other major scydmaenine lineages, e.g. , Mastigini, Eutheiini, Cephenniini, and Glandulariini, ...
