Abstract A new genus Amblomma gen. nov. of fossil beetles is erected and can be assigned to the family Ommatidae because its two procoxal cavities are contiguous and the articulations of the abdominal ventrites are abutting. The new genus is similar to Zygadenia Handlirsch, 1906 (=Notocupes Ponomarenko, 1964), Tetraphalerus Waterhouse, 1901, Rhobdocupes Ponomarenko, 1966 and Sinocupes Lin, 1976, but can be distinguished from other genera according to the following characters: the second segment… 
New fossil ommatid (Coleoptera: Archostemata: Ommatidae) from Jehol Biota of Western Liaoning, China
TLDR
One new genus and one new species of fossil ommatid, Odontomma trachylaena gen. et sp.
Redescriptions of beetles of the Notocupes generic complex (Coleoptera: Archostemata: Ommatidae) from the Lower Cretaceous of Buryatia
TLDR
The term “generic complex” is proposed for 12 previously synonymized fossil genera of Ommatidae and descriptions contain selected morphological characters that will be used in future redescriptions.
Early Jurassic Coleopterans from the Mintaja Insect Locality, Western Australia
TLDR
The ecology of these fossils is difficult to interpret, although some of the beetles were likely aquatic, and the Ommatidae and Elateridae were both likely xylophilous, though many of these similarities are based on morphotaxa and may be superficial in nature.
New ommatids of Ommatinae (Coleoptera: Archostemata: Ommatidae) from the Yixian Formation of Liaoning, China
TLDR
Four new fossil species of the family Ommatidae from the Yixian Formation of western Liaoning, China are described and a preliminary analysis of geographical distribution suggests a possible migration pathway of the genus Brochocoleus.
The thoracic morphology of Archostemata and the relationships of the extant suborders of Coleoptera (Hexapoda)
TLDR
Important evolutionary changes linked with this branching event are simplifications of the thoracic skeleton resulting in reduced degrees of freedom, and a distinct simplification of the muscle system, which culminates in Polyphaga, which are strongly supported as a clade.
A new cupedid genus (Coleoptera: Archostemata: Cupedidae) from Jehol Biota of western Liaoning, China
A new genus including two new species of fossil cupedids, Latocupes fortis gen. and sp. nov. and L. bellus gen. and sp. nov., is described from the Yixian Formation of western Liaoning Province,
Taxonomic Review of Fossil Coleopterous Families (Insecta, Coleoptera). Suborder Archostemata: Superfamilies Coleopseoidea and Cupedoidea
The paper is the first of a series, which aims to present a consistent interpretation of the suprageneric taxa of fossil beetles in the current century and their generic and species composition.
NEW CUPEDIDS FROM THE MIDDLE JURASSIC OF INNER MONGOLIA, CHINA (COLEOPTERA: ARCHOSTEMATA)
TLDR
The fauna of ptyctimous mites from South Africa is described and analysed and identification keys of the supercohorts, superfamilies, families, genera, subgenera and species are provided.

TLDR
The results of this dating study indicate that the lower Yixian fossil horizons are not Jurassic but rather are at least 20 Myr younger, placing them within middle Early Cretaceous time.
