The occurrence of Wrinkled Bark Beetle Rhysodes sulcatus Fabricius, 1787 (Coleoptera: Rhysodidae), a rare and threatened saproxylic beetle of primordial and old-growth forests in the Palearctic region, is reported for Montenegro. The species has a discontinuous and localized distribution in the Alpine region, and is included in Habitat Directive and in the risk categories of the IUCN red list for saproxylic beetles. Rhysodes sulcatus was found in the Biogradska Gora National Park, in the north-western part of the Bjelasica mountain range in the Dinaric Alps (Montenegro), during September 2021 while surveying the beetle fauna in a old-growth beech forests at about 1,084 m elevation. This finding extends its known distribution into Alpine region and further confirms the important biogeographical role of this mountainous territory. I discuss distribution and conservation issues and provide recommended conservation measures that may be useful for protecting many other saproxylic beetles (e.g., increase of large deadwood masses).

Background This paper presents the results of 30 years of field studies on the Caraboidea fauna of the southern Sikhote-Alin Mountain, Russian Far East. Material was collected at 300+ geographical localities within 18 administrative and seven urban districts of the Primorsky Krai, Russia. A total of 55,953 adult ground beetles belonging to 426 subspecies, 411 species, 86 genera and three families were studied. The families Rhysodidae and Trachypachidae are represented by one species each, while the family Carabidae the remaining 409 species. The resulting sampling-event dataset includes 12,852 occurrences. New information This is the first dataset underlying an accurate and referenced taxonomic composition, as well as the geographic distribution of the Caraboidea in the southern Sikhote-Alin Mountains, Primorsky Krai, Russian Far East.

The wrinkled bark beetle Rhysodes sulcatus is an endangered saproxylic beetle listed in the European Habitats Directive and in the Bern Convention (Annex II). It is considered a relict of primeval forests and belongs among the most threatened saproxylic beetles in Europe.The purpose of this study was to identify the key habitat requirements of the species. The study was carried out at several locations within different forest types in mid elevation forests dominated by oak, beech and spruce and montane beech‐fir forests in the Czech Republic, Slovakia and Croatia.Coarse woody debris was checked for the presence of the beetle, and parameters of each inspected dead wood unit and its surroundings were recorded, including diameter, length, humidity, insolation, decomposition level and rot type. Surrounding forest characteristics, such as canopy density, main tree species, undergrowth, the amount and quality of the dead wood were also recorded.The analysis shows that the presence of the beetle is affected mainly by the diameter of dead wood as well as its humidity, as R. sulcatus was almost exclusively found in large, moist and well rotten fallen logs with a diameter greater than 60 cm. These findings may provide useful guidelines for sustainable forest management, specifically emphasising the need to retain large fallen logs at sites inhabited by R. sulcatus populations.

The coleopterous fauna was investigated from the surroundings of Réde between 2011-2017. Methods of research were the following: traps baited with red wine and bananas, pitfall trapping, sweep¬netting, observations in the field. 110 pitfall trap samples were collected in several habitat types (beech forest, oak forest, acacia grove, pine forest, meadows, moorish habitat, riparian willow and alder) of 11 localities. Six Natura 2000 species (Lucanus cervus (Linnaeus, 1758), Cerambyx cerdo Linnaeus, 1758, Morimus funereus Mulsant, 1863, Rosalia alpina (Linnaeus, 1758), Limoniscus violaceus (P.W.J. Müller, 1821), Cucujus cinnaberinus (Scopoli, 1763)) are present among the 31 protected beetle species. The collected material includes 2 rare species Neoplinthus porcatus (Panzer, 1798), Bembidion elongatum (Dejan, 1831), comments about these are presented. [ABSTRACT FROM AUTHOR]

Omoglymmius (s. str.) wukong sp. n. (Coleoptera: Rhysodidae: Omoglymmiini) is described from Xizang, China.

All scientific names of Trachypachidae, Rhysodidae, and Carabidae (including cicindelines) recorded from America north of Mexico are catalogued. Available species-group names are listed in their original combinations with the author(s), year of publication, page citation, type locality, location of the name-bearing type, and etymology for many patronymic names. In addition, the reference in which a given species-group name is first synonymized is recorded for invalid taxa. Genus-group names are listed with the author(s), year of publication, page citation, type species with way of fixation, and etymology for most. The reference in which a given genus-group name is first synonymized is recorded for many invalid taxa. Family-group names are listed with the author(s), year of publication, page citation, and type genus. The geographical distribution of all species-group taxa is briefly summarized and their state and province records are indicated.One new genus-group taxon, Randallius new subgenus (type species: Chlaenius purpuricollis Randall, 1838), one new replacement name, Pterostichus amadeus new name for Pterostichus vexatus Bousquet, 1985, and three changes in precedence, Ellipsoptera rubicunda (Harris, 1911) for Ellipsoptera marutha (Dow, 1911), Badister micans LeConte, 1844 for Badister ocularis Casey, 1920, and Agonum deplanatum Ménétriés, 1843 for Agonum fallianum (Leng, 1919), are proposed. Five new genus-group synonymies and 65 new species-group synonymies, one new species-group status, and 12 new combinations (see Appendix 5) are established.The work also includes a discussion of the notable private North American carabid collections, a synopsis of all extant world geadephagan tribes and subfamilies, a brief faunistic assessment of the fauna, a list of valid species-group taxa, a list of North American fossil Geadephaga (Appendix 1), a list of North American Geadephaga larvae described or illustrated (Appendix 2), a list of Geadephaga species described from specimens mislabeled as from North America (Appendix 3), a list of unavailable Geadephaga names listed from North America (Appendix 4), a list of nomenclatural acts included in this catalogue (Appendix 5), a complete bibliography with indication of the dates of publication in addition to the year, and indices of personal names, supraspecific names, and species-group names.
