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> Current Reseach</em> section are subject to peer-review. There are no page charges for manuscripts accepted for publication.</p>https://www.ntnu.no/ojs/index.php/chironomus/article/view/5037We need chironomid symposia!2022-12-30T21:57:06+00:00Torbjørn Ekremtorbjorn.ekrem@ntnu.no2022-12-30T00:00:00+00:00Copyright (c) 2022 Torbjørn Ekremhttps://www.ntnu.no/ojs/index.php/chironomus/article/view/4737A case of phoresis of midges on Zygoptera2022-01-18T12:46:14+00:00Narcís Pratnprat@ub.edu2022-03-07T00:00:00+00:00Copyright (c) 2022 Narcís Prathttps://www.ntnu.no/ojs/index.php/chironomus/article/view/4833The Chironomus species studied by Letha Karunakaran in Singapore, with a review of the status of selected South-East Asian Chironomus2022-06-03T14:58:07+00:00Jon Martinj.martin@unimelb.edu.au<p>In the 1960s Letha Karunakaran studied the chironomid fauna of Singapore but<span class="Apple-converted-space"> </span>faced a lack of sufficiently detailed descriptions to enable identification of her material with any certainty.<span class="Apple-converted-space"> </span>She recognized seven species of <em>Chironomus </em>(s.s) but sent me fixed larval material of only four of these which she tentatively identified as <em>C. apicatus</em> Johannsen 1932, <em>C. costatus </em>Johannsen 1932, <em>C. javanus</em> Kieffer 1924, and <em>C. stupidus </em>Johannsen 1932. She sent fixed larvae to me for confirmation of her identifications, but died before I was able to determine accurate identities from morphology alone. With additional comparative material, along with polytene chromosome banding patterns and DNA barcode sequence from the mitochondrial COI gene, the species have been identified as a form of <em>C. flaviplumus</em> (auct, not Tokunaga)(here called <em>C. flaviplumus </em>Type B),<span class="Apple-converted-space"> </span><em> C. circumdatus</em> Kieffer 1916<em>, </em>probably<em> C.</em> <em>striatipennis </em>Kieffer 1910,<em><span class="Apple-converted-space"> </span></em> and <em>Kiefferulus barbatitarsis</em> (Kieffer 1911), respectively. The identification of one species as a form of <em>C. flaviplumus</em> required an assessment of the present state of knowledge of this species where the name has been applied to at least five different species. Determination of a valid name for this species is not currently possible. The confusion of species identification is an indication that there are a number of closely related species which constitute a “<em>C. flaviplumus</em> group”.</p>2022-09-15T00:00:00+00:00Copyright (c) 2022 Jon Martinhttps://www.ntnu.no/ojs/index.php/chironomus/article/view/4926Where the rare species hide: a new record of Parachironomus monochromus (van der Wulp, 1874) for Slovakia from artificial urban waterbodies2022-06-03T10:51:47+00:00Ladislav Hamerlikladislav.hamerlik@gmail.comPeter Bitušíkpeter.bitusik@umb.skSilvia Bartókovásilvia.bartokova@student.umb.skJakub Potančokjakub.potancok1@gmail.com<p><em>Parachironomus monochromus</em> (van der Wulp, 1874) was recorded for the first time in Slovakia in an urban pond and a city fountain along with a total of 27 other chironomid taxa recorded both as larvae and pupal exuviae.

Results are limited but indicate nematodes may infest winter-active chironomid communities and significantly affect host chironomid biology. Further research on winter-active insects should include investigations into nematode parasitism to better understand how climate change will affect chironomid survival at the population and community level.</p> <p>.</p>2022-12-28T00:00:00+00:00Copyright (c) 2022 Hannah Bodmer, Corrie Nyquisthttps://www.ntnu.no/ojs/index.php/chironomus/article/view/4596A home at last!

The type material is missing, and the published description and illustrations are limited. Although the genus name <em>Changania</em> Tseng, 1965 becomes a new junior synonym of <em>Thienemanniella</em> Kieffer, 1911, <em>Thienemanniella choui</em> (Tseng 1965), new combination, should be treated as a <em>nomen dubium</em>.</p>2022-03-07T00:00:00+00:00Copyright (c) 2022 Martin Spies, Art Borkent, Peter S.

Cranstonpscranston@gmail.comMatt Kroschkrosch.mattn@police.qld.gov.auHongqu Tangtownningt@gmail.com<p>Molecular data support two distinct species of <em>Nilotanypus</em> Kieffer (Chironomidae: Tanypodinae) differentiated on morphology in all stages. Each is described as <em>Nilotanypus haplochelus</em> new species and <em>Nilotanypus ctenochelus</em> new species respectively. Morphological differentiation is stronger in the larva and pupa, with adult stages less well differentiated, as seems usual in the genus. Both species are distributed widely across the Australian continent, but seemingly absent from offshore islands and Tasmania. A tendency towards lotic psammophily (sand-dwelling) is evident, with sympatry at some tropical / subtropical locations. Additional molecular data from non-Australian taxa indicates that <em>N. ctenochelus</em> is sister to all other sampled taxa and <em>N. haplochelus</em> to an undescribed species from oriental China. Review of all stages of several non-Australian species requires revised generic diagnoses, and, critically, recognition of <em>Pentaneura comata</em> Freeman 1953 as synonymous with the type of the genus, <em>Nilotanypus remotissimus</em> Kieffer 1923 (new synonym).</p>2022-06-27T00:00:00+00:00Copyright (c) 2022 Peter S.
