We present a genome assembly from an individual male Ocys tachysoides (ground beetle; Arthropoda; Insecta; Coleoptera; Carabidae). The primary assembly has a total length of 493.76 megabases. Most of the primary assembly (83.47%) is scaffolded into 7 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled, with a length of 18.2 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.

We present a genome assembly from an individual male Leistus fulvibarbis (ground beetle; Arthropoda; Insecta; Coleoptera; Carabidae). The assembly contains two haplotypes with total lengths of 261.71 megabases and 218.71 megabases. Most of the haplotype 1 assembly (67.81%) was scaffolded into 23 chromosomal pseudomolecules, including the X sex chromosome. Most of haplotype 2 (71.48%) is scaffolded into 22 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 18.39 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.

We present a genome assembly from an individual female Chaetocnema hortensis (flea beetle; Arthropoda; Insecta; Coleoptera; Chrysomelidae). The assembly contains two haplotypes with total lengths of 384.62 megabases and 383.80 megabases. The haplotype 1 assembly and the haplotype 2 assembly each contain 10 chromosomal pseudomolecules, including the X sex chromosome; these account for 93.56% and 93.72% of their respective sequences. The mitochondrial genome has also been assembled, with a length of 19.64 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.

We present a genome assembly from an individual female Magdalis barbicornis (weevil; Arthropoda; Insecta; Coleoptera; Curculionidae). The assembly contains two haplotypes with total lengths of 1,457.47 megabases and 1,399.10 megabases. Most of the haplotype 1 assembly (89.76%) was scaffolded into 21 chromosomal pseudomolecules, including the X sex chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 23.36 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.

We present a genome assembly from an individual female Rhyzobius forestieri (ladybird beetle; Arthropoda; Insecta; Coleoptera; Coccinellidae). The primary assembly has a total length of 753.45 megabases. Most of the primary assembly (94.89%) is scaffolded into 9 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled, with a length of 18.95 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.

We present a genome assembly from an individual female Coccinella magnifica (Scarce Seven-spot Ladybird; Arthropoda; Insecta; Coleoptera; Coccinellidae). The assembly contains two haplotypes with total lengths of 498.77 megabases and 558.91 megabases. Most of the haplotype 1 assembly (85.36%) was scaffolded into 10 chromosomal pseudomolecules, including the X sex chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 19.5 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.

New distribution records and a redescription are presented for Caperhantus cicurius (Fabricius, 1787), a diving beetle endemic to the Cape region of South Africa, which is only distantly related to other Afrotropical dytiscids. We show that the species is much more widely distributed than previously recognized and present details of occupied habitats for the first time. Caperhantus cicurius occurs throughout the winter rainfall zone in South Africa, from Namaqualand to the Eastern Cape Province, particularly in temporary waters in the Fynbos and Succulent Karoo biomes.

We present a genome assembly from an individual male Harpalus rufipes (a ground beetle; Arthropoda; Insecta; Coleoptera; Carabidae). The genome sequence spans 890.50 megabases. Most of the assembly is scaffolded into 19 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled and is 17.37 kilobases in length. Gene annotation of this assembly on Ensembl identified 13,884 protein-coding genes.

The ant genus Strumigenys is a hyper diverse pantropical group of specialised predatory leaf litter dwelling ants. Species richness peaks within tropics, with few species extending into the West Palaearctic realm. A significant proportion of Strumigenys species known from the West Palaearctic are non-native, spread via human commerce, and predominately establishing populations within artificially heated greenhouses. In Britain, two Strumigenys species were previously known, S. rogeri Emery, 1890 and S. perplexa (Smith, 1876). Here we add a third species, S. emmae (Emery, 1890) based upon specimens from the humid tropical biomes at the Eden Project, Cornwall (UK). A single record outlined here is noted as the earliest known record of S. emmae from Europe thus far, pre-dating previous records by four years. We provide high resolution images, measurements, and discussion on the ecology of the species. In addition, an updated key to the Strumigenys of the Europe is supplied.
