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...

Abstract Exoskeletal morphological structures of all extant genera currently included into Mastigitae are very well studied, whereas the larvae are poorly known. Larval morphology provides a valuable character system for phylogenetic reconstructions, and as all hitherto carried out analyses of Mastigitae were based on adult characters only, it is important to fill this major gap by studying immature stages. We here describe in detail the second- and third-instar larvae of the South African ant-l...

Abstract † Praphennium gen. nov. is described to include † Praphennium carinatum sp. nov. from the Cenomanian Myanmar amber. Two other species are placed in the same genus, but they remain unnamed. This is the first known extinct genus of the large tribe Cephenniini that includes cosmopolitan extant ant-like stone beetles with uniquely modified mouthparts adapted to feed on armored mites. † Praphennium shares most exoskeletal characters with its extant relatives, and the structure and position o...

The Afrotropical genus Oreoeudesis Franz was previously known to occur in Tanzania, Kenya and Cameroon. A new species, Oreoeudesis ruandensis sp. nov. is described on the basis of a material coming from Rwanda. Differences in cephalic, pronotal, mesonotal and genital structures justify placing the new species in a separate subgenus, Suboreon subgen. nov. Morphological structures of O. ruandensis, especially the large composite eyes and fully developed wings, seem to be plesiomorphic as compared ...

Some Scydmaeninae are strict specialists that feed exclusively on heavily sclerotized oribatid or uropodine mites. The chapter reviews the available literature on the feeding habits of Euconnus , Stenichnus , Scydmaenus , and Cephennium beetles and presents previously unpublished observations on Neuraphes and Microscydmus species. Species with unspecialized mouthparts attack the mite’s gnathosoma, removing movable parts to gain access to soft tissues. They also often remove genital or anal plate...

Larvae of ant-like stone beetles are exceptionally poorly known. Scydmaeninae comprises over 5000 species, but the immature stages have been described for less than 0.5% of them; the pupa has been illustrated for four species, and the first larval instar for only one species. In several tribes, larvae still remain unknown, and many descriptions are inaccurate or poorly illustrated. Chaetotaxic structures have been coded in only six species. Our knowledge of larval Scydmaeninae is so fragmentary ...
