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> Jon Martin Copyright (c) 2022 Jon Martin http://creativecommons.org/licenses/by/4.0 2022-09-15 2022-09-15 35 44 49 10.5324/cjcr.v0i35.4833 Where the rare species hide: a new record of Parachironomus monochromus (van der Wulp, 1874) for Slovakia from artificial urban waterbodies https://www.ntnu.no/ojs/index.php/chironomus/article/view/4926 <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. Our finding emphasizes the role of urban waterbodies as habitats for rare species and for maintaining and documenting aquatic biodiversity in cities.</p> Ladislav Hamerlik Peter Bitušík Silvia Bartóková Jakub Potančok Copyright (c) 2022 Ladislav Hamerlik, Peter Bitušík, Silvia Bartóková, Jakub Potančok http://creativecommons.org/licenses/by/4.0 2022-09-22 2022-09-22 35 50 53 10.5324/cjcr.v0i35.4926 Nematodes infest winter-active chironomids in Minnesota trout streams https://www.ntnu.no/ojs/index.php/chironomus/article/view/5029 <p>We present preliminary findings of the effects of nematode infestation on winter-active chironomid biology, and how short-term temperature spikes could affect host-parasite interactions. 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> Hannah Bodmer Corrie Nyquist Copyright (c) 2022 Hannah Bodmer, Corrie Nyquist http://creativecommons.org/licenses/by/4.0 2022-12-28 2022-12-28 35 54 57 10.5324/cjcr.v0i35.5029 A home at last! Changania choui Tseng, 1965 belongs to Thienemanniella Kieffer, 1911 (Diptera: Chironomidae: Orthocladiinae) https://www.ntnu.no/ojs/index.php/chironomus/article/view/4596 <p>The midge <em>Changania choui</em> Tseng, 1965 (Insecta, Diptera, Nematocera), originally described in the family Cecidomyiidae and recently transferred to the Ceratopogonidae, is recognised as an adult female in the Chironomidae, subfamily Orthocladiinae. 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> Martin Spies Art Borkent Peter S.

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> Peter S.
