CHIRONOMUS Journal of Chironomidae Research <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="" 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="" target="_new">The Effect of Open Access</a>).</li> </ol> Describing the undiscovered Alyssa Anderson ##submission.copyrightStatement## 2018-12-27 2018-12-27 31 2 3 10.5324/cjcr.v0i31.2887 Cricotopus (s. str.) latellai sp. n., a new rheophilic species of the tremulus-group from the Italian and French Maritime Alps (Diptera: Chironomidae) <p><em>Cricotopus</em> (<em>Cricotopus</em>) <em>latellai</em> sp. n. is described and diagnosed based on material comprising male and female pharate adults, pupal exuviae and larvae recently collected in some glacial streams in both the Italian and French Maritime Alps. Taxonomic notes provided in this paper include: description of <em>C. latellai</em> sp. n. as male and female adults, pupal exuviae and last instar larvae. The diagnosis of the <em>Cricotopus tremulus</em>-group is supplemented with additional characters in the male adult and pupal exuviae. <em>Cricotopus latellai </em>sp. n. keys near <em>C. mantetanus</em> Moubayed-Breil, 2016 and <em>C. storozhenkoi</em> Makarchenko &amp; Makarchenko, 2016. Geographical distribution of <em>C. latellai</em> sp. n. is currently restricted to the Italian and French Maritime Alps. It belongs to the Tyrrhenian community of glacial relic species, which are considered to be indicators of climate change in this biogeographical region. Remarks, taxonomic position, and ecology of the new described species are given.</p> Joel Moubayed-Breil Patrick Ashe ##submission.copyrightStatement## 2018-06-29 2018-06-29 31 4 15 10.5324/cjcr.v0i31.2498 A new species in the Rheocricotopus (R.) effusus group from Canada with a review of the Nearctic species of Rheocricotopus and Parametriocnemus (Chironomidae: Orthocladiinae) <p><em>Rheocricotopus </em>(<em>Rheocricotopus</em>)<em> reduncusoides </em>sp. n. is described from Bathurst Island, Nunavut, Canada. Its discovery was made while curating and examining specimens deposited by H. V. Danks in 1969 at the Canadian National Collection in Ottawa, Canada. We also report the first Canadian record of <em>Parametriocnemus hamatus</em> (Johannsen, 1934) from Québec, based on previously unsorted material deposited at the Canadian National Collection. In this paper we provide distributional records of the Nearctic species of <em>Rheocricotopus</em> Thienemann and Harnisch and <em>Parametriocnemus </em>Goetghebuer, and present a key to the Nearctic adult males of these genera.</p> Armin Namayandeh David V.

Pupal exuviae of two species are described for the first time: <em>P</em>. <em>barbatulus</em> Sublette and <em>P</em>. <em>clavus</em> Roback. Adult and larval features are included for <em>P</em>. <em>barbatulus</em>. In addition, specimens of Nearctic <em>P</em>. <em>denticulatus</em> Sublette are compared to Palearctic <em>P</em>. <em>signatus</em> (Zetterstedt) to determine if exuviae can separate these species or suggest that <em>P</em>. <em>signatus</em> is a senior synonym. Finally, associated pupal and larval traits of <em>P.</em> <em>prolongatus</em> Roback are compared to the original description, corroborating the theory that features are unique enough to warrant subgeneric status.</p> Alexander Egan Peter Langton ##submission.copyrightStatement## 2018-12-27 2018-12-27 31 30 36 10.5324/cjcr.v0i31.2865 Oviposition behavior and host records for the parasitic midge Trichochilus lacteipennis (Johannsen) (Chironomidae: Orthocladiinae) <p>Adult female <em>Trichochilus lacteipennis</em> were observed to extrude long strings of eggs (up to 15 cm) in flight over a lake in Maine, USA. Once extruded females dropped to the water surface and released the strings. Larvae of <em>T. lacteipennis</em> are parasitic on <em>Elliptio complanata</em> at this site and probably additional unionid mussel species elsewhere. Based on our dissections of parasitized mussels and previous reports, it appears <em>T. lacteipennis</em> spend all or nearly all of their larval life within their mussel host, with first instars initially free-living inside the mantle. At some point larvae enter the marsupium and complete larval development on a diet of mussel eggs and/or glochidia before pupating within the marsupium. </p> David Harley Funk Sherman Roberts Alan Graham ##submission.copyrightStatement## 2018-02-07 2018-02-07 31 37 42 10.5324/cjcr.v0i31.2436 First record of the genus Heterotrissocladius (Chironomidae: Orthocladiinae) from the Neotropical region <p>Here we report the occurrence of <em>Heterotrissocladius</em> (Diptera: Chironomidae: Orthocladiinae) for the first time in Central America, as well as in the Neotropical region. The report is based on sub-fossil chironomid head capsules from surface sediments of a high elevation lake, Lago Magdalena, Guatemala.</p> Ladislav Hamerlik Fabio Laurindo Da Silva ##submission.copyrightStatement## 2018-08-28 2018-08-28 31 43 46 10.5324/cjcr.v0i31.2601 Memories of D.
