The short-range distributions of cave-dwelling Campodeidae species, together with their ancient origin, make them a key taxonomic group from a paleogeographical perspective. Nevertheless, the systematic validity of several campodeid lineages remains unresolved. In this paper, we examine the tachycampoid group (sensu Bareth & Condé 1981) by reassessing its principal taxonomic traits in comparison with Campodeinae and Plusiocampinae. We suggest that the monophyly of the entire tachycampoid lineage (sensu Bareth & Condé 1981) should be rejected based on new morphological, and ecological data for several species of Juxtlacampa , Tachycampa , and Paratachycampa . Furthermore, we provide a comprehensive revision of the entire genus Juxtlacampa and describe two new cave-adapted species: Juxtlacampa gabrielleae Sendra & Ferreira sp. nov. and Juxtlacampa xkiq Sendra & Wynne sp. nov.

The Carboniferous orthoconic or slightly cyrtoconic cephalopod family Brachycycloceratidae Furnish, Glenister & Hansman, 1962 is well described based on material from North America, whereas the Early Carboniferous European occurrences of this family are much less well-known. Almost all records from the Rhenish Mountains have been assigned to the single species Brachycycloceras scalare (d’Archiac & de Verneuil, 1842). This species is revised here and used as the type species of the genus Rhenocycloceras gen. nov. The new Early Carboniferous species Rhenocycloceras conicum sp. nov. and R. denckmanni sp. nov. from the Rhenish Mountains of Germany, R. macdiarmadai sp. nov. from Co. Leitrim in Ireland and R. africanum sp. nov. from the Anti-Atlas of Morocco are described. Additionally, two new Early Carboniferous species of Caneycycloceras Niko & Mapes, 2011 are described from the Rhenish Mountains; these are C. rotersorum sp. nov. and C. fuerstenbergorum sp. nov. The early Late Carboniferous species B. koninckianum (d’Orbigny, 1849) is discussed on the basis of material from the type locality in Belgium.

We present a world catalog of the family Chelodesmidae Cook in Cook & Collins, 1895 (Diplopoda: Polydesmida), compiling all currently valid genera and species (up to the end of 2024), along with their synonymies, original descriptions, and relevant taxonomic literature. The catalog reflects the current classification of the family into subfamilies and, where available, tribes. For each taxon, we provide a chronological list of bibliographic citations, as well as type locality information when known. The work also summarizes historical patterns of taxonomic activity, highlighting the main contributors and publication venues. In addition, we present distribution maps showing the geographic occurrence of the family by country and for each tribe. This catalog offers a comprehensive and updated foundation for future research on the systematics and biogeography of Chelodesmidae.

Sierola Cameron, 1881 is a highly diverse genus of aculeate ectoparasitoid wasps found across the Indo-Pacific region. Species are found on almost all Pacific high islands and mainland Asia. A few species have been described from Australia, but the genus has never been comprehensively treated there. Here, the Australian Sierola is reviewed for the first time, focusing on taxa that lack a high, sharp, clypeal carina. One hundred sixty-nine species from all regions are described as new, and S. vibrissata Ward, 2013 is recorded from Australia for the first time. As a result, there are now 177 species of Sierola recorded from Australia. This remains a first step on fully analyzing the genus, and at least as many or more species remain undescribed.

The northeastern Atlantic species of the gastropod genus Jujubinus Monterosato, 1884 (Trochidae, Cantharidinae) are reviewed based on an integrative taxonomic approach. Based on a comprehensive phylogenetic framework of cantharidine genera, it is suggested that the scope of the genus Jujubinus should be restricted to a radiation in the northeastern Atlantic and the Mediterranean, not including the tropical Indo-West Pacific species frequently ascribed to it. For Trochus montagui Wood, 1828, traditionally ascribed to Jujubinus , we did not find unequivocal evidence of it belonging in this clade, but rather we found some indication of a closer relationship with Clelandella miliaris (Brocchi, 1814) than with the Jujubinus clade. Thirteen morphospecies were checked against a DNA-barcoding dataset ( cox1 ) and a molecular phylogenetic framework ( cox1 , 16S , single genes and combined datasets, analysed by Bayesian inference and Maximum Likelihood analyses). Twenty-two secondary species hypotheses were eventually retained. For fifteen of them an available name has been found; seven are herein described as new.
