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.

Abstract The taxonomic status of previously misplaced species of an ant-like stone beetle from Spanish amber (Albian) is clarified. Specimens of Kachinus magnificus (originally placed as incertae sedis within Scydmaenitae) were re-examined and their characters were found different from those of the type species of Kachinus from Myanmar amber. Consequently, Archeutheia gen. nov. is proposed to accommodate the Spanish species, resulting in Archeutheia magnifica comb. nov. Moreover, in a comprehens...

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 The Neotropical genus Leptochromus Motschulsky (Coleoptera: Scydmaenidae) is revised, and a phylogenetic analysis of Clidicini is presented. Leptochromus includes five species distributed from Veracruz, Mexico to Manaus, Brazil. Leptochromus fulvescens Motschulsky, L. mexicanus (Sharp) and L. agilis (Sharp) are considered valid species. Leptochromus bicolor O'Keefe, sp.n. from Veracruz, Mexico and L. palaeomexicanus O'Keefe, sp.n. from Miocene amber from Chiapas are described. Male geni...

We compared the postabdominal architecture of Mastigini with extremely long (Stenomastigus) or short (Palaeostigus) aedeagus. A novel mode of copulation was discovered: males of Stenomastigus insert a paramere between the female's abdomen and elytra, and the intromission is stabilized by several structures of both sexes. The intrinsic aedeagal mechanism is indicated as responsible for inflating the endophallus, and the long flagellum does not penetrate the ductus spermathecae during copulation. ...

Abstract Amber (‘Burmite’) from the Hukawng Valley of Myanmar has been known since at least the 1st century AD. It is currently being produced from a hill known as Noije Bum, which was first documented as a source of amber in 1836. Several geologists visited the locality between 1892 and 1930. All of them believed that the host rocks to the amber are Tertiary (most said Eocene) in age, and this conclusion has been widely quoted in the literature. However, recent work indicates a Cretaceous age. ...

Genera of Eutheiini are reviewed and Eutheimorphus is removed from this tribe of ant-like stone beetles (Scydmaeninae) and transferred to Cephenniini. A monogeneric Marcepaniini trib.n. is described to accommodate Marcepania gen.n. from Malaysia, with five species: M. semengohensis sp.n. (the type species of Marcepania), M. tuberculata sp.n., M. seramaensis sp.n., M. minutissima sp.n. and M. elongata sp.n. A phylogenetic analysis of all genera of Cephenniini, Eutheiini and Marcepaniini based on ...

Ant-like stone beetles (Coleoptera: Scydmaenidae) include more than 4,850 described species in about 90 genera main- tained as a separate cosmopolitan family since 1815. Recent authors have hypothesised that Scydmaenidae might be rooted deep inside rove-beetles (Staphylinidae). To test this hypothesis we analysed 206 parsimoniously informative larval and adult morpho- logical characters scored for 38 taxa. Strict consensus topologies from the shortest trees in all 12 analyses consistently placed...

Abstract Oxyporinae is a distinct staphylinid subfamily characterized by a large body, remarkably long and projecting mandibles, and large, crescent-shaped terminal labial palpomeres. Previously, only three compression fossils from the Lower Cretaceous Yixian Formation in China were known for the subfamily from the Mesozoic Era. This study describes a remarkable new species, Oxyporus cretaceous sp. nov., based on a single specimen in Upper Cretaceous Burmese amber. This finding is the earliest r...

Abstract A second species of the extinct scydmaenine genus Cretoleptochromus Cai & Huang, C . burmiticus sp. nov., is described and figured based on three exquisitely preserved specimens embedded in mid-Cretaceous Burmese amber. The new taxon possesses an extremely elongate body form and strongly extended legs and antennae that provide reliable means for species diagnosis and a ready separation from the only known congener, the type species C. archaicus Cai & Huang, also reported from Burmese am...

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 †Lepicerus mumia Jaloszynski & Yamamoto, sp. nov. is described based on a Cenomanian Myanmar amber inclusion. This is the third known and the best preserved fossil of ‘lepiceroid’ myxophagan beetles, making it possible to carry out a more detailed comparative study than previously published findings. Detailed analyses of diagnostic characters given by previous authors for †Haplochelus (†Haplochelidae) and †Lepichelus (= Lepiceroides ) (Lepiceridae) led to conclusions that some features ...

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, ...

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 ...

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 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...
