Integrative taxonomy of coastal Cafiusbistriatus (Erichson) species complex (Coleoptera, Staphylinidae)
A systematic review of the marine littoral
(Erichson) along the eastern Pacific and the western Atlantic coasts including the Caribbean Sea is presented based on morphological and molecular (
and
) characters. Specimens of the
species complex [
,
Bierig, and
(LeConte)] are similar to each other, including the form and structure of the aedeagus, and they can be treated as cryptic species. Detailed micromorphological characters (SEM) and molecular analyses support the validity of these three species. Intraspecific genetic divergence of
using uncorrected p-distance among individuals of
ranged from 0% to 1.56%, while interspecific divergence among three species ranged from 4.90% to 14.59%. All three species were each supported as a single lineage using
and
on both parsimony and maximum likelihood trees. Morphological characters among

Coastal Staphylinidae (Coleoptera): A worldwide checklist, biogeography and natural history
We provide a list of the 392 described species of Staphylinidae confined to coastal habitats worldwide. The list is in taxonomic sequence by subfamily, tribe, and genus and includes 91 genera. We provide the page reference of the original description of every species and genus listed and of many synonyms. We note the existence of recent reviews, phylogenies and keys of each of the tribes and genera included. Coastal Staphylinidae contain eight subfamilies: Microsilphinae, Omaliinae, Pselaphinae, Aleocharinae, Oxytelinae, Scydmaeninae, Paederinae, and Staphylininae.By 'coastal habitats' we mean habitats existing on the sea coast and subject to inundation or at least splashing by the very highest tides. This includes rocky, boulder, coral, sandy, and muddy seashores, and at least portions of salt-marshes, estuaries, and mangrove swamps. We exclude the sand dune habitat and higher parts of sea-cliffs.The list notes distribution of all the species, first according to the ocean or sea on whose shores it has been recorded, and second by country (and for the larger countries by province or state). Although this distribution is undoubtedly incomplete, it provides a basis for future development of a dedicated database.The 'Habitats, Habits, and Classificatory Notes' section is designed to provide ecologists with further taxonomic and ecological information. It includes references to descriptions of the immature stages, behavior of adults and immatures, their food, natural enemies, and habitat. We would have preferred to separate these entities, but current knowledge of ecology is developed in few instances beyond natural history.The Pacific Ocean basin was the origin and contributed to the dispersal of the majority of specialist coastal Staphylinidae at the level of genus. However, at the level of species, species belonging to non-coastal-specialist genera are about as likely to occur on the shores of other oceans as on the shores of the Pacific. This difference is a reflection of the antiquity of coastal genera and species.A complete bibliography, and habitat and habitus photographs of some representative coastal Staphylinidae species are provided.

Silica nanoparticles as pesticide against insects of different feeding types and their non-target attraction of predators
The agricultural use of silica (SiO
2
) nanoparticles (NPs) has the potential to control insect pests while the safety and tritrophic effects on plants and beneficial natural enemies remains unknown. Here, we evaluate the effects of silica NPs on insect pests with different feeding niches, natural enemies, and a plant. Silica NPs were applied at different concentrations (75–425 mg/L) on field-cultivated faba bean and soybean for two growing seasons. The faba bean pests, the cowpea aphid
Aphis craccivora
and the American serpentine leafminer
Liriomyza trifolii
, and the soybean pest, the cotton leafworm
Spodoptera littoralis
, were monitored along with their associated predators. Additional laboratory experiments were performed to test the effects of silica NPs on the growth of faba bean seedlings and to determine whether the rove beetle
Paederus fuscipes
is attracted to cotton leafworm-infested soybean treated with silica NPs. In the field experiments, silica NPs reduced the populations of all three insect pests and their associated predators, including rove beetles, as the concentration of silica NPs increased. In soybean fields, however, the total number of predators initially increased after applying the lowest concentration. An olfactometer-based choice test found that rove beetles were more likely to move towards an herbivore-infested plant treated with silica NPs than to a water-treated control, suggesting that silica NPs enhance the attraction of natural enemies via herbivore-induced plant volatiles. In the laboratory, while silica NPs inhibited the development of faba bean roots at 400 mg/L, they did not affect germination percentage, germination time, shoot length, or vigor index compared to the control.

The oldest fossil record of Pseudopsinae from the Lower Cretaceous Yixian Formation of northeastern China (Coleoptera: Staphylinidae: Pseudopsinae)
The Cretaceous witnessed a radiation of rove beetles (Staphylinidae), the most species-rich beetle family. Although most staphylinid subfamilies have been documented from Cretaceous strata over the world, there has been no fossil record of the subfamily Pseudopsinae until a recently reported fossil from the 99-Ma-old Myanmar amber. Here we describe a new compression fossil from the Lower Cretaceous Yixian Formation of northeastern China. It is described as
Cretaceonanobius fossilis.
gen. et sp. nov. and assigned to the extant subfamily Pseudopsinae, based on the well-preserved carinae on the pronotum, a carina on ventrites II and III, and distinctly separated mesocoxae. The discovery of
Cretaceonanobius fossilis
gen. et sp. nov. backdates the earliest fossils record of Pseudopsinae to 125 Ma in the Northern Hemisphere and sheds new lights on the evolution history and paleobiogeography of this subfamily.

DESCRIPTION OF GENITAL STRUCTURES OF VELLEIOPSIS MARGINIVENTRIS FAIRMAIRE, 1882 (COLEOPTERA: STAPHYLINIDAE: STAPHYLININAE) FROM TURKEY1
Male and female genital structures of Velleiopsis marginiventris Fairmaire, 1882 collected in Ankara, Turkey, are described and illustrated for the first time. V. marginiventris was described by Fairmaire in 1882 from Bulgaria, and it also occurs in Turkey having been collected from Gumushane. Male genitalia and the genital segments of both sexes were extracted using standard methods; figures were drawn using a Leica MZ16A stereoscobic microscope. The structure of male genitalia of genus Velleiopsis has been studied only by Coiffait and only the drawings of median lobe and paramere of male genital structure of V. varendorffi were given but tergite X and sternite IX were not. When our results were compared with V. varendorffi, the genitalia greatly differed by the shape of median lobe and paramere and also with the arrangement of peg setae. While median lobe is asymmetrically sinuate in V. marginiventris, it is symmetric and straight in V. varendorffi.

Contributions to Paederus Fabricius, 1775, Paederidus Mulsant & Rey, 1878 and Uncopaederus Korge, 1969 (Coleoptera, Staphylinidae, Paederinae) fauna of Türkiye
In this study, between 2009 and 2021, total of more than thousand specimens belonging to the genus Paederus Fabricius, 1775, Paederidus Mulsant & Rey, 1878 and Uncopaederus Korge, 1969 were collected in Türkiye. Most of the specimens examined were collected from the Marmara, Aegean, Central Anatolia, Western and Central Blacksea Regions. The specimens collected in this study were collected with aspirators and light traps. As a result of field studies, a total of eight species belonging to three genera were recorded. These are Paederidus rubrothoracicus (Goeze, 1777); P. ruficollis (Fabricius, 1777); Paederus balcanicus Koch, 1938, P. fuscipes Curtis, 1826, P. riparius Linnaeus, 1758, P. littoralis Gravenhorst, 1802, P. mesopotamicus Eppelsheim, 1889 and Uncopaederus signiventris (Smetana, 1962). Among these species, P. rubrothoracicus and P. ruficollis from the Marmara and Central Black Sea Regions, P. fuscipes from the Western Black Sea Region, and P. riparius from the Marmara Region of Turkey were reported for the first time. The presence of P. balcanicus in Türkiye has been confirmed. U. signiventris is endemic and distributed only in the Black Sea Region. In addition, P. balcanicus and U. signiventris are figured for the first time.

Good-bye Scydmaenidae, or why the ant-like stone beetles should become megadiverse Staphylinidae sensu latissimo (Coleoptera)
Ant-like stone beetles (Coleoptera: Scydmaenidae) include more than 4,850 described species in about 90 genera maintained as a separate cosmopolitan family since 1815. Recent authors have hypothesised that Scydmaenidae might be rooted deep inside rove-beetles (Staphylinidae). To test this hypothesis we analysed 206 parsimoniously informative larval and adult morphological characters scored for 38 taxa. Strict consensus topologies from the shortest trees in all 12 analyses consistently placed Scydmaenidae as sister to (Steninae + Euaesthetinae) in a monophyletic Staphylinine Group (with or without Oxyporinae). The single fully resolved and most consistently supported topology maintains a monophyletic Staphylinine Group consisting of Oxyporinae + (Megalopsidiinae + ((\"Scydmaenidae\" + (Steninae + Euaesthetinae)) + (Leptotyphlinae + (Pseudopsinae + (Paederinae + Staphylininae))); Solierius lacks larval data and is ambiguously placed within the Group. Eight analyses of variably aligned 18S rDNA data for 93 members of Staphylinoidea under parsimony, neighbour-joining and Bayesian approaches were markedly inconsistent, although partly congruent with the Scydmaenidae + (Steninae + Euaesthetinae) hypothesis. Our results strongly suggest that ant-like stone beetles do not form an independent family, but are morphologically modified members of Staphylinidae and, consequently, should be treated as a 32nd recent subfamily within the megadiverse Staphylinidae sensu latissimo. Formal taxonomic acts are: Scydmaeninae Leach, 1815, status novus (= Scydmaenidae Leach, 1815); Scydmaenitae Leach, 1815, status novus (= Scydmaeninae Leach, 1815); Mastigitae Fleming, 1821, status novus (= Mastiginae Fleming, 1821); Hapsomelitae Poinar & Brown, 2004, status novus (= Hapsomelinae Poinar & Brown, 2004). The family Staphylinidae sensu latissimo becomes the largest in Coleoptera and in the whole of the Animal Kingdom, with 55,440 described species (extant plus extinct), thus surpassing Curculionidae with an estimated 51,000 described species.
