https://www.ntnu.no/ojs/index.php/chironomus <p>The CHIRONOMUS Journal of Chironomidae Research is devoted to publishing peer-reviewed research articles related to all aspects of chironomid research. The journal also serves as an updated news bulletin for the Chironomidae research community. The journal has one issue per year, but articles are published online continuously after they are accepted. The journal is open access, and can be downloaded freely from this website. All research articles submitted to CHIRONOMUS<em>&nbsp;Current Reseach</em>&nbsp;section are subject to peer-review. There are no page charges for manuscripts accepted for publication.</p> Norwegian University of Science and Technology en-US CHIRONOMUS Journal of Chironomidae Research 0172-1941 <p>Authors who publish with this Open Access journal agree to the following terms:</p> <ol> <li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a&nbsp;<a href="http://creativecommons.org/licenses/by/3.0/" target="_new">Creative Commons Attribution License</a> 4.0 that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.</li> <li>Authors are able to enter into separate, additional contractual arrangements for the non-exclusive distribution of the journal's published version of the work (e.g., post it to an institutional repository or publish it in a book), with an acknowledgement of its initial publication in this journal.</li> <li>Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work (See&nbsp;<a href="http://opcit.eprints.org/oacitation-biblio.html" target="_new">The Effect of Open Access</a>).</li> </ol> https://www.ntnu.no/ojs/index.php/chironomus/article/view/6282 <p><em>Parametriocnemus lausannensis</em> Widmann, Marle &amp; Brodin sp. n. is described and figured based on five barcoded specimens collected in the city of Lausanne, Switzerland. This species is morphologically similar to <em>P. stylatus</em> (Spärck, 1923), <em>P. lundbeckii</em> (Johannsen, 1905), <em>P. scotti </em>(Freeman, 1953) and <em>P. adzharicus</em> Kownacki &amp; Zosidze, 1973 which is raised here from subspecies to species level. Males of <em>P</em>.<em> lausannensis</em> can be separated from related species by the squarish shape of the inferior volsella and by its DNA barcodes.</p> Christian Widmann Pierre Marle Yngve Brodin Copyright (c) 2025 Christian Widmann, Pierre Marle, Yngve Brodin http://creativecommons.org/licenses/by/4.0 2025-06-08 2025-06-08 39 10.5324/cjcr.v0i39.6282 https://www.ntnu.no/ojs/index.php/chironomus/article/view/6302 <div><span lang="EN-US">In this communication, we report on correcting DNA barcoding records of <em>Limnophyes stagnum</em> Namayandeh, Guerra &amp; Ram, 2024. The five sequences we submitted to BOLD and published in Namayandeh et al. (2024) under <em>L. stagnum</em>match the CO1 sequences of <em>Limnophyes</em> sp. 14ES and the two species are not conspecific. Both species were collected from the type locality of <em>L. stagnum</em> but at different times with a misassumption that both species represent a single taxon. We have corrected our records in BOLD, replacing the names of the five sequences with <em>Limnophyes</em> sp. 14ES. Additionally, we obtained and uploaded a single CO1 sequence of <em>L. stagnum</em> in BOLD and incorporated it into new molecular analyses reported here. Based on our results, the closest sequences to <em>L. stagnum</em> were those of <em>Limnophyes natalensis </em>(Kieffer, 1914). The minimum K2P distance of <em>L. stagnum</em> with <em>L. natalensis </em>was 10.0% (average 11.4%), large enough to support the delimitation of <em>L. stagnum</em> sp. nov. from <em>L. natalensis</em>. Further discussion on the morphological differences of the two species and those of <em>L. stagnum</em> and <em>Limnophyes</em> sp. 14ES are provided.</span></div> Armin Namayandeh Edris Ghaderi Jeffrey L.
