Abstract
Abstract The new family Apotomouridae fam. nov. (Coleoptera: Polyphaga: Tenebrionoidea) is described based on Multispinus multispinosus gen. et sp. nov. and Apotomoura fortiscrura gen. et. sp. nov. from Burmese amber (lower Cenomanian, ca. 99 Ma). The retractile wedge-shaped body and tarsal formula 5-5-4 placed Apotomouridae fam. nov. in Tenebrionoidea. The new family shares similarities with the Mordellidae, whereas the absence of pygidium and the combination of other microstructures assigned it more closely to the Jurassic beetle genus Wuhua. The morphological characters suggest the similar flower feeding style as to Mordellidae and Ripiphoridae, which represent the flower diet and pollinating strategy in the Tenebrionoidea.

Beetles (Coleoptera) are the most diverse and species-rich group of insects, and a robust, time-calibrated phylogeny is fundamental to understanding macroevolutionary processes that underlie their diversity. Here we infer the phylogeny and divergence times of all major lineages of Coleoptera by analyzing 95 protein-coding genes in 373 beetle species, including ~67% of the currently recognized families. The subordinal relationships are strongly supported as Polyphaga (Adephaga (Archostemata, Myxo...

Summary During the mid-Cretaceous, angiosperms diversified from several nondiverse lineages to their current global domination [1], replacing earlier gymnosperm lineages [2]. Several hypotheses explain this extensive radiation [3], one of which involves proliferation of insect pollinator associations in the transition from gymnosperm to angiosperm dominance. However, most evidence supports gymnosperm–insect pollinator associations, buttressed by direct evidence of pollen on insect bodies, curren...

Abstract A new species of Dicranoptycha from Burmese amber (lowermost Cenomanian, Upper Cretaceous) is described, Dicranoptycha burmitica sp. nov. The morphology comparison with their closest recent and fossil relatives is provided. The distribution of fossil representatives of Dicranoptycha is presented and their morphological traits discussed.

The phylogenetic relationships of the beetle superfamily Tenebrionoidea are investigated using the most comprehensive genetic data set compiled to date. With ∼34,000 described species in approximately 1250 genera and 28 families, Tenebrionoidea represent one of the most diverse and species-rich superfamilies of beetles. The interfamilial relationships of the Tenebrionoidea are poorly known; previous morphological and molecular phylogenies recovered few well-supported and often conflicting relati...

The Coleoptera (beetles) constitute almost one-fourth of all known life-forms on earth. They are also among the most important pollinators of flowering plants, especially basal angiosperms. Beetle fossils are abundant, almost spanning the entire Early Cretaceous, and thus provide important clues to explore the co-evolutionary processes between beetles and angiosperms. We review the fossil record of some Early Cretaceous polyphagan beetles including Tenebrionoidea, Scarabaeoidea, Curculionoidea, ...

This paper contains a review of beetle species (Coleoptera) described from Baltic amber. The compiled checklist contains 434 species from 149 extinct and 138 extant genera. At this moment, 90 families are registered. The best known and therefore most diverse families are: Staphylinidae (77 described spp.), Curculionidae (46 spp.), Carabidae (32 spp.), Scirtidae (21 spp.), Cleridae (17 spp.), Elateridae (16 spp.), Dermestidae (16 spp.) and Cerambycidae (15 spp.). Possibly, about 530 species of be...

The beetle Mordellaria friedrichi sp. nov. is described from the Baltic amber. The new species differs from extant species of the genus in the shape of the eyes and antennae and in the ratios of the length of the pygidium and length of the elytron, pronotum, and anal sternite.

Amber from northern Myanmar has been commercially exploited for millennia, and it also preserves the most diverse palaeobiota among the worlds' seven major deposits of Cretaceous amber. Recent estimated ages vary from Albian to Cenomanian, based on palynology, an ammonoid, and Mesozoic insect taxa preserved within the amber. The burmite-bearing rock is sedimentaryand consists mainly of rounded lithic clasts (0.03w0.15 mm in diameter), with minor fragments of quartz and feldspar. Among the lithic...

Abstract Within this study the subfamily Praemordellinae is reviewed and the holotype of Praemordella martynovi Scegoleva-Barovskaja, 1929 is re-described. The genera Cretanaspis Huang and Yang, 1999, Mirimordella Liu et al., 2007, Bellimordella Liu et al., 2008 and Wuhua Wang and Zhang, 2011 is attributed to Praemordellinae. One new species, Wuhua peregrina sp. nov., is erected based on two well-preserved specimens from the Middle Jurassic Daohugou Biota (Inner Mongolia, China). The morphologic...
