Data on the Passandridae collection of the Natural History Museum (London, United Kingdom), including type specimens of 50 names, of them 29 valid and 21 invalid, are presented. The type status of several specimens is clarified. Images of type and other significicant specimens are provided for 55 taxa, mainly for the first time. The history of the...

In the evolution of praying mantids, eusocial termites, cave cockroaches and the beetle/ant/bee/wasp-mimicking umenocoleoids, at a single Early Cretaceous diversification point (127 Ma) each lacked hierarchical structure, and independent explosive radiations are revealed. Adult male, female and individuals of unidentified sex of new cockroaches (Co...
Article
We present a genome assembly from an individual male Aelia acuminata (the bishop’s mitre shieldbug; Arthropoda; Insecta; Hemiptera; Pentatomidae). The genome sequence is 1,170 megabases in span. The majority of the assembly (99.78%) is scaffolded into 8 chromosomal pseudomolecules, with the X and Y sex chromosome assembled.

New methods in taxonomy and systematics can influence the overall practice of formally naming and describing biodiversity. DNA barcoding has been controversial since its emergence, but now, large scale species descriptions exclusively based on barcodes have created what can be called a 'new quality of performance'. Its limitations are discussed fro...
Article
Colour polymorphism offers rich opportunities for studying the eco-evolutionary mechanisms that drive the adaptations of local populations to heterogeneous and changing environments. We explored the colour morph diversity and composition in a Chrysomela lapponica leaf beetle across its entire distribution range to test the hypothesis that environme...
Article
New Prioninae material from Guadalcanal, Solomon Islands has led to the re-evaluation of two undetermined female specimens from 1965 in the collection of the Natural History Museum, London. The male and additional females have since been found, and the distinctive new species Psalidocoptus satori sp. nov. is described in this paper, the first addit...

ABSTRACT We describe reports of adult brown marmorated stink bugs (Halyomorpha halys) in the UK and discuss the implications for possible establishment of this global invasive species. Reports of interceptions at ports date back to 2010, but more recently (since 2018) adults have been observed free in the environment within England. Sentinel pherom...

This article presents a summary of species recorded in the Wildlife Garden since the last report (Sivell et al. 2020). Recording and monitoring in the Wildlife Garden during 2020 and 2021 was again disrupted by the coronavirus pandemic, with repeated lockdowns resulting in staff being forced to work from home and no recording days, such as bioblitz...

Abstract. For 160 years, Anthrenus pimpinellae isabellinus Küster, 1848 has been considered a subspecies of A. pimpinellae Fabricius, 1775. However, habitus shape differs between the subspecies with A. p. isabellinus being broader than A. p. pimpinellae and resembling more closely A. dorsatus Mulsant & Rey, 1868. Here A. p. pimpinellae and A. p. is...

Two ancient Egyptian child mummies at the University of Tartu Art Museum (Estonia) were, according to museum records, brought to Estonia by the young Baltic-German scholar Otto Friedrich von Richter, who had travelled in Egypt during the early 19th century. Although some studies of the mummies were conducted, a thorough investigation has never been...

Ischaliidae (Tenebrionoidea) is a small, relatively poorly known family of beetles, with fewer than 50 described species. The Coleoptera collections of the Natural History Museum, London are among the largest and most comprehensive in the world, but the Ischaliidae holding is relatively small (136 specimens, 18 species). However, this collection is...

The earliest eusociality of cockroaches is conserved in termites. New wood-boring mole “roaches” from Cretaceous Burmite belong to a new, most primitive, termite family Pabuonqedidae. Cock- roach symplesiomorphies include hypognathous head concealed under pronotum/ paranotalia, regular wing venation, clavus, long cercal sensillae, carinated legs, u...

Elmidae is one of the most diverse families of aquatic beetles, with more than 1500 species in 148 genera. Cylloepus is the genus with the most species in Americas, with 52 species and 2 subspecies currently known. The genus is easily recognised by external morphology; body elongate, pronotum with a longitudinal impression on the disc and elytra st...

Half of Borneo's forest has been logged and oil palm plantations have replaced millions of hectares of forest since the 1970's. While this extensive land-use change has been shown to reduce species richness across landscapes, there is limited current knowledge on how deforestation affects the spatial arrangement of ecological communities. Identifyi...

A lectotype for Pogonocherus setosus Audinet-Serville (currently Cosmotomidius setosus) is designated. Cosmotomidius Melzer is transferred from Pogonocherini Mulsant to Acanthoderini Thomson, and the retention of the former tribe is questioned and discussed. The differences between Cosmotomidius and Zikanita Lane are discussed. A new genus and spec...

The lowland forest of Borneo is threatened by rapid logging for timber export and clearing for the expansion of timber and oil palm plantations. This combination of processes leaves behind landscapes dotted with small, often heavily-degraded forest fragments. The biodiversity value of such fragments, which are easily dismissed as worthless, is unce...

Aporrhipis flexilis Pascoe, 1887 is the sole species of a monospecific genus of beetles from Brazil, originally described in the family Ripiphoridae. Despite the fact that this genus was moved to Lycidae, its correct tribal placement remains uncertain. In this study, A. flexilis is redescribed, its tribal placement is discussed, and it is tentative...

Introduction In summer 2006, dead branches of Scots pine Pinus sylvestris from 2-5 cm in diameter were collected by MR in two old pine forest localities in Scotland 75 km apart, with a view to rearing longhorn beetles (Cerambycidae) using the method described in Rejzek (2006). One recently fallen branch was collected from the ground and found to co...
