Most soil and litter arthropods are unidentifiable based on current DNA barcode reference libraries.

We are far from knowing all species living on the planet. Understanding biodiversity is demanding and requires time and expertise. Most groups are understudied given problems of identifying and delimiting species.

Systematics and biogeography of Appalachian Anillini, and a taxonomic review of the species of South Carolina (Coleoptera, Carabidae, Trechinae, Anillini).

In the eastern United States, 74 species of Anillini in two genera have been described, with most belonging to Casey. Until now, no systematic framework has existed for this large genus, hampering integrative studies. Using DNA sequences from 101 Nearctic species, we present a well-resolved molecular phylogeny supporting a sound systematic framework.

Bio-inspired design of hard-bodied mobile robots based on arthropod morphologies: a 10 year systematic review and bibliometric analysis.

This research presents a 10-year systematic review based on bibliometric analysis of the bio-inspired design of hard-bodied mobile robot mechatronic systems considering the anatomy of arthropods. These are the most diverse group of animals whose flexible biomechanics and adaptable morphology, thus, it can inspire robot development. Papers were reviewed from two international databases (Scopus and Web of Science) and one platform (Aerospace Research Central), then they were classified according to: Year of publication (January 2013 to April 2023), arthropod group, published journal, conference proceedings, editorial publisher, research teams, robot classification according to the name of arthropod, limb's locomotion support, number of legs/arms, number of legs/body segments, limb's degrees of freedom, mechanical actuation type, modular system, and environment adaptation.

A second species of the pill millipede genus Wesener, 2012 (Diplopoda, Glomerida) from the Great Smoky Mountains, USA.

We describe a second species of Wesener, 2012, a genus of pill millipede endemic to the southern Appalachians, based on morphological and molecular evidence. The fauna of Glomerida in America is characterized by its low diversity, and is only the fifth species of the order known from the eastern United States. Our phylogenetic analyses based on COI sequences recover a tentatively monophyletic lineage including both eastern American genera Cook, 1896 and , with a common ancestor in the Late Cretaceous to Mid Eocene and extant diversity within genera dating back to the Miocene.

Mitochondrial Genomes Assembled from Non-Invasive eDNA Metagenomic Scat Samples in Critically Endangered Mammals.

The abundance of many large-bodied vertebrates, both in marine and terrestrial environments, has declined substantially due to global and regional climate stressors that define the Anthropocene. The development of genetic tools that can serve to monitor population's health non-intrusively and inform strategies for the recovery of these species is crucial. In this study, we formally evaluate whether whole mitochondrial genomes can be assembled from environmental DNA (eDNA) metagenomics scat samples.

Long-term population persistence of flightless weevils (Eurhoptus pyriformis) across old- and second-growth forests patches in southern Appalachia.

Background: Southern Appalachian forests are dominated by second-growth vegetation following decades of intensive forestry and agricultural use, although some old-growth patches remain. While it's been shown that second-growth areas may exhibit comparable species richness to old-growth in the area, the extent to which populations of arthropods in second-growth areas have persisted vs. recolonized from other areas remains unexamined.

A revision of the genus LeConte, 1876 (Curculionidae, Cryptorhynchinae) of America north of Mexico.

The genus LeConte, 1876 is revised for America north of Mexico. Eight species are recognized including LeConte, 1876, (LeConte, 1876), (Hamilton, 1893), resurrected name, and five new species as follows: new species (type locality, Texas, Hidalgo County, Bentsen Rio Grande State Park), new species (type locality, Texas, Bandera County, Lost Maples State Natural Area), new species (type locality, Texas, Bandera County, Lost Maples State Natural Area), new species (type locality, Texas, Brewster County, Big Bend National Park), and new species (type locality, Alabama, Winston County, Bankhead National Forest). Descriptions or redescriptions, and images of taxonomically important structures are presented for all species.

Revision of the genus Motschulsky, 1855 (Staphylinidae, Pselaphinae: Jubini). Corrections.

In my revision of the genus Pselaphomorphus Motschulsky, 1855 (Vásquez-Vélez 2016) the depository of the holotype of P. cayennensis Vásquez-Vélez, 2016 was not listed. As a result, the requirements of Article 16.

Revision of the genus Pselaphomorphus Motschulsky, 1855 (Staphylinidae, Pselaphinae: Jubini).

The genus Pselaphomorphus Motschulsky, 1855 is revised to include 33 species. The type species, Pselaphomorphus sculpturatus Motschulsky, 1855, and the previously described species P. longiceps Raffray, 1890 and P.
