Rheanischia new genus, type species Rheanischia brevicornis new species (Eucnemidae, Anischiinae) is described from the Lower Cretaceous of Liaoning, China. The presence of this species in early Cretaceous deposits provides new insight into the evolution of basal lignicolous Eucnemidae clades. Both Anischiinae and Palaeoxeninae species diversified in a world dominated by gymnosperms, before the main radiation of angiosperms. More than 95% of modern eucnemid larvae have a Palaeoxenus-type highly modified head structure, but contrary to the Palaeoxenus larva, they develop in angiosperm wood. Anischiinae utilize angiosperms as well, but their head capsule shows no such modifications. These facts prove that highly specialized morphological features do not offer definite proof of similar way of life in the distant past, nor should non-modified structures be taken as proof for another kind of substrate choice. Eucnemidae have invaded angiosperms with two quite different morphological adaptations. This fact may have implications for the evolution of all clicking elateroids.

A new genus and species of the basal bethylid subfamily Holopsenellinae is described and figured from a female in Burmese amber, the first occurrence of the lineage outside of the Early Cretaceous deposits of Lebanon. Holopsenelliscus pankowskiorum gen. and sp. nov., differs from other holopsenellines most notably in the discontinuous anterior wing margin and open subdiscal cell, among other traits. The genus and species are described in full and distinguished from Holopsenella primotica Engel et al. in Lebanese amber and Cretabythus sibiricus Evans in Taimyrian amber. A key to the genera of Holopsenellinae is provided.

Mesocoprophilus clavatus gen. et sp.n., a new rove beetle belonging to the Recent subfamily Oxytelinae, is described and illustrated on the basis of a well-preserved specimen from the Lower Cretaceous Yixian Formation near Huangbanjigou, Beipiao City, Liaoning Province, Northeast China. This new genus can be placed in the extant tribe Coprophilini as supported by its general habitus, sub-contiguous mesocoxae, 5-segmented metatarsi, and abdominal segments III–VII each with two pairs of paratergites. In addition, it displays some features resembling the more basal tribe Euphaniini, including clavate antennae and short and poorly-sclerotized abdominal sternite II.

High living standards and a comfortable modern way of life are related to an increased usage of various plastic products, yielding eventually the generation of an increased amount of plastic debris in the environment. A special concern is on microplastics (MPs), recently classified as contaminants of emerging concern (CECs). This review focuses on MPs’ adverse effects on the environment based on their bioactivity. Hence, the main topic covered is MPs’ ecotoxicity on various aquatic (micro)organisms such as bacteria, algae, daphnids, and fish. The cumulative toxic effects caused by MPs and adsorbed organic/inorganic pollutants are presented and critically discussed. Since MPs’ bioactivity, including ecotoxicity, is strongly influenced by their properties (e.g., types, size, shapes), the most common classification of MPs types present in freshwater are provided, along with their main characteristics. The review includes also the sources of MPs discharge in the environment and the currently available characterization methods for monitoring MPs, including identification and quantification, to obtain a broader insight into the complex problem caused by the presence of MPs in the environment.

AbstractA new genus and species of the planktonic shrimp family Luciferidae,Sume marcosin. gen. n. sp., is described and illustrated from material collected in calcareous shale of the late Early Cretaceous (Aptian–Albian) Romualdo Formation, Araripe Basin, northeastern Brazil. The material is very well preserved, including the antennae, stalked eyes, second and third maxillipeds, pleopods, and uropods, and represents the first described fossil of the family Luciferidae.UUID:http://zoobank.org/fdf825b8-6fe9-42ae-8fc7-73c220eec03a

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.
