Glaesotropis rohdendorfi sp. nov. belongs to the subgenus Electranthribus, described from Eocene Rovno amber. The new species is similar to G. zherikhini from Baltic amber. It is the first described beetle from the Olevsk amber locality, the sixth amber species reported from the Zhytomyr region, the first record of the subgenus Electranthribus, and the third Anthribidae from Rovno amber. An aggregation of glaesacarid mites as a syninclusion with the fungus weevil is reported for the first time.

A new mid-Cretaceous rhopalosomatid wasp, Cretolixon alatum Lohrmann gen. et sp. nov., is described from Burmese (Kachin) amber. The new genus has a unique mixture of characters, some of which are only known from the recent brachypterous genus Olixon and others of which are known only from the recent macropterous genera. Thus, Cretolixon not only provides further evidence for the monophyly of the family but also contributes evidence for the monophyly of the Rhopalosomatinae.

In this paper, we describe a new species of embolomere from 255-million-year-old fossil beds from northern China. This group of ancient animals is closely related to amniotes (reptiles, birds, and mammals) and was previously thought to have gone extinct around 273 million years ago. The new discovery indicates that North China, with its ancient tropical rain forest, became a last reservoir for these animals right before the end-Permian mass extinction.

The new weevil Igneonasus rudolphi gen. et sp. nov. of the tribe Ceutorhynchini is described from the late Oligocene of Fossillagerstätte Enspel, Germany. The new genus is similar to the Recent genus Stenocarus and the largest representative of the supertribe Ceutorhynchitae. It is the first fossil Curculionidae species described from the paleolake Enspel. In this ancient ecosystem, weevils were at least sometimes an important food resource for the cyprinid fish Palaeorutilus enspelensis.
