Koch, 1850, and updates the counts of extant and extinct genera and species through the end of 2025. Including the revisions implemented herein, there are 459 genus-group names available in Scorpiones by the end of 2025. Of these, 318 refer to currently accepted extant genera (220), subfossil genera (1) and extinct genera (97). Fifty-four genus-group names are newly synonymized, raising to 145 the number in synonymy, whereas sixteen genus-group names are revalidated and/or newly elevated to the rank of genus. Including the revisions implemented herein, Scorpiones includes 3,089 currently accepted species-group names (2,918 extant species, 1 subfossil species, and 170 extinct species) and 22 <em>nomina dubia</em>. Forty-seven species-group names are newly synonymized, whereas 43 species-group names are revalidated and/or newly elevated to the rank of species. 197 (62%) of the currently accepted genus-group names were described since 1950. Despite this descriptive activity, the suprageneric phylogeny and classification of Recent scorpions remains in a state of flux and largely decoupled from the phylogeny and classification of fossil forms.</span></span></span></p>2026-04-21T00:00:00+12:00Copyright (c) 2026 Magnolia Press Limitedhttps://www.mapress.com/mt/article/view/megataxa.19.2.3<p><strong>Taxonomic revision of the wolf spider genus <em>Artoria </em>(Araneae, Lycosidae, Artoriinae) from Northern Territory and Queensland, with additions to the fauna of New South Wales and the Australian Capital Territory</strong></p>2025-10-30T12:26:35+13:00ANDRÉ W.

Three species are recorded from the Northern Territory: <em>A. parvula</em> Thorell, 1877 (♂♀, type species), <em>A. superelliptica</em> <strong>sp. nov. </strong>(♀) and <em>A. vectis</em> <strong>sp. nov. </strong>(♂♀). Twenty-seven species (including 18 new ones) are recorded from Queensland: <em>A. albopilata</em> (Urquhart, 1893) (♂♀), <em>A. berenice</em> (L. Koch, 1877) (♂♀), <em>A. bicornuta</em> <strong>sp. nov.</strong> (♂), <em>A. catinata</em> <strong>sp. nov.</strong> (♂♀), <em>A. coclearia</em> <strong>sp. nov.</strong> (♂♀), <em>A. cunicularia</em> <strong>sp. nov.</strong> (♂♀), <em>A. geniculata</em> <strong>sp. nov.</strong> (♂♀), <em>A. globula</em> <strong>sp. nov.</strong> (♂♀), <em>A. grahammilledgei</em> Framenau & Baehr, 2018 (♂♀), <em>A</em>.<em> halterata</em> <strong>sp. nov.</strong> (♀), <em>A. hamifera</em> <strong>sp. nov.</strong> (♂♀), <em>A. laciniata</em> <strong>sp. nov.</strong> (♀), <em>A. lineata</em> (L.

This study also added 13 new species of <em>Artoria </em>to New South Wales, seven of these species endemic to the state—<em>A. abscondita </em><strong>sp. nov.</strong> (♀), <em>A. ancorata </em><strong>sp. nov.</strong> (♀), <em>A. cucurbita</em> <strong>sp. nov.</strong> (♀), <em>A. limitata</em><strong> sp. nov.</strong> (♀), <em>A.</em> <em>longinqua</em><strong> sp. nov.</strong> (♀), <em>A. serpentidens</em><strong> sp. nov.</strong> (♂♀), and <em>A. tenuis</em><strong> sp. nov.</strong> (♀), and one also occurring in the Australian Capital Territory—<em>A. pedroi</em><strong> sp. nov.</strong> (♂♀). Summing up, 39 species are taxonomically treated in this paper, including 28 new ones. In addition, we propose the <em>beaury </em>and<em> lingulata</em> species-groups, and redefine the <em>lineata</em> species-group based on male and female genital characters.</span></span></span></p>2026-04-21T00:00:00+12:00Copyright (c) 2026 Magnolia Press Limitedhttps://www.mapress.com/mt/article/view/megataxa.19.2.4<p><strong>BlasTax—a user-friendly stand-alone tool to leverage the BLAST+ program for molecular taxonomy</strong></p>2025-10-28T14:14:58+13:00MIGUEL VENCESm.vences@tu-braunschweig.deSTEFANOS PATMANIDISstefanpatman91@gmail.comNIKITA KULIKOVn.kulikov@leibniz-lib.deIKER IRISARRIiker.irisarri@mncn.csic.esANJA-KRISTINA SCHULZanjakris@posteo.deLAILA-DENISE ROTHEl.rothe@tu-braunschweig.deALICE PETZOLDpetzoldalice@gmail.comMARK D.

BlasTax is designed to serve both general users of local BLAST who seek a simple and user-friendly interface, and taxonomists engaged in phylogenomics and museomics projects. BlasTax is driven by a graphical user interface that makes various BLAST functions accessible without separately installing the BLAST+ executables. It introduces several advanced modes to retrieve matching reads from FASTQ files of high-throughput sequencing of archival DNA from recent or historical collection material, to append matching sequences to existing alignments, or to decontaminate sequence data sets from sequences of non-target taxa. The program also comprises functions for the preparation of sequence files to be used as reference or query for BLAST, as well as utilities for sequence merging based on species labels, codon trimming and codon-aware multiple sequence alignments.</span></span></span></p>2026-04-21T00:00:00+12:00Copyright (c) 2026 Magnolia Press Limited
