CHIRONOMUS Journal of Chironomidae Research 2019-03-23T09:04:57+00:00 Torbjørn Ekrem Open Journal Systems <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> Describing the undiscovered 2019-03-23T09:04:52+00:00 Alyssa Anderson 2018-12-27T22:11:14+00:00 ##submission.copyrightStatement## Cricotopus (s. str.) latellai sp. n., a new rheophilic species of the tremulus-group from the Italian and French Maritime Alps (Diptera: Chironomidae) 2019-03-23T09:04:56+00:00 Joel Moubayed-Breil Patrick Ashe <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> 2018-06-29T12:10:51+00:00 ##submission.copyrightStatement## A new species in the Rheocricotopus (R.) effusus group from Canada with a review of the Nearctic species of Rheocricotopus and Parametriocnemus (Chironomidae: Orthocladiinae) 2019-03-23T09:04:54+00:00 Armin Namayandeh David V. Beresford <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> 2018-12-27T10:49:47+00:00 ##submission.copyrightStatement## Descriptions of four Nearctic Procladius Skuse pupal exuviae 2019-03-23T09:04:53+00:00 Alexander Egan Peter Langton <p>Associated <em>Procladius</em> Skuse (<em>Holotanypus</em> Roback) material from the Sublette collection was found to have specimens with undescribed immature stages. 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> 2018-12-27T10:50:14+00:00 ##submission.copyrightStatement## Oviposition behavior and host records for the parasitic midge Trichochilus lacteipennis (Johannsen) (Chironomidae: Orthocladiinae) 2019-03-23T09:04:57+00:00 David Harley Funk Sherman Roberts Alan Graham <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> 2018-02-07T00:00:00+00:00 ##submission.copyrightStatement## First record of the genus Heterotrissocladius (Chironomidae: Orthocladiinae) from the Neotropical region 2019-03-23T09:04:55+00:00 Ladislav Hamerlik Fabio Laurindo Da Silva <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> 2018-08-28T00:00:00+00:00 ##submission.copyrightStatement## Memories of D.
