<i>Zavoticus yini</i> gen. et sp. nov., a New Euaesthetine Rove Beetle From Mid-Cretaceous Kachin Amber (Coleoptera: Staphylinidae). [PDF]
Ecol EvolWe describe and illustrate a new euaesthetine rove beetle from mid‐Cretaceous Kachin amber, Zavoticus yini gen. et sp. nov. Based on morphological comparisons and a phylogenetic analysis, Zavoticus is placed in the Octavius generic group. ABSTRACT We describe and illustrate Zavoticus yini gen. et sp.

Structural Diversity of Adipokinetic Hormones in the Coleopteran Suborder Polyphaga (Excluding Cucujiformia). [PDF]
Arch Insect Biochem PhysiolAdipokinetic hormones of Polyphaga beetles (minus Cucujiformia series) were sequenced and confirmed via mass spectrometry. Schgr‐AKH‐II is assumed as ancestral AKH in Coleoptera. Radiation of AKH diversity during the evolution of Scarabaeoidea. ABSTRACT Beetles are the largest animal group, in general.

Arthropod abundances track soil fertility across a lowland tropical forest landscape. [PDF]
J Anim EcolThis study reveals strong, diverse associations between soil phosphorus and the abundances of understorey arthropods across a lowland tropical forest landscape. These patterns were not paralleled in an adjacent site‐level fertilisation experiment, raising the interesting possibility that arthropod–phosphorus associations could be mediated by spatial ...

A new fossil species of the extant genus Vicelva from mid-Cretaceous Kachin amber (Coleoptera: Staphylinidae). [PDF]
Ecol EvolA new species of the extant staphylinid genus Vicelva Moore & Legner, V. rasilis sp. nov., is reported from mid‐Cretaceous Kachin amber of northern Myanmar. The pollen‐containing coprolite attached to the beetle and the crystals within the beetle body provide valuable information about the biology and taphonomy of the fossil.

Sexual Dimorphism of Tarsal Attachment Devices and Their Relation to Mating in Coccinellidae. [PDF]
J MorpholWe explore the coevolution of male attachment devices and female elytral morphology in coccinellids. Specifically: (1) Disco‐setae are present in males of some species, located on the hairy pad which during mating hold on female elytra. (2) The area of male disco‐setae is extended when females have smooth elytra, and reduced when females have hairy ...

The cryptonephridial/rectal complex: an evolutionary adaptation for water and ion conservation. [PDF]
Biol Rev Camb Philos SocABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire and maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in which the renal organs and gut have been dramatically reorganised. Parts of the renal or Malpighian tubules (MpTs) form a close

The Morphology of the Rare Beetle Silphopsyllus desmanae (Leiodidae), a Commensal of the Semiaquatic Russian Desman. [PDF]
J MorpholWe document in detail the morphology of Silphopsyllus desmanae (Leiodidae), a commensal of the endangered semiaquatic Russian desman, and discuss it with respect to phylogeny and function. Silphopsyllus is much less adapted to life on a semiaquatic host than the closely related beaver beetle Platypsyllus.

An annotated checklist of family Hydraenidae (Coleoptera: Staphylinoidea) in the North Africa [PDF]
African Journal of Biological Sciences, 2021 Data from previous literature were used to compile a checklist of the of north African hydraenid beetles. Members of Hydraenidae are mostly 0.5-3 mm in length and genitalia of different species under the same taxonomic group are almost indistinguishable. The external morphology of several taxa, e.g., Ochthebiinae, is largely variable.

High levels of species' extirpation in an urban environment-A case study from Berlin, Germany, covering 1700-2023. [PDF]
Ecol EvolOur study compiled and analysed spatio‐temporal species' extirpation on a broad taxonomic coverage at the city scale. We revealed high number of extirpations, which are in the twenty‐firstcentury already comparable with previous centuries, and showed that cities might be suitable systems for studying species' extirpation processes due to their small ...
