CHIRONOMUS Journal of Chironomidae Research 2018-10-03T08:04:37+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> Cricotopus (s. str.) latellai sp. n., a new rheophilic species of the tremulus-group from the Italian and French Maritime Alps (Diptera: Chironomidae) 2018-10-03T08:04:35+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## Oviposition behavior and host records for the parasitic midge Trichochilus lacteipennis (Johannsen) (Chironomidae: Orthocladiinae) 2018-10-03T08:04:37+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> 2018-02-07T09:21:29+00:00 ##submission.copyrightStatement## First record of the genus Heterotrissocladius (Chironomidae: Orthocladiinae) from the Neotropical region 2018-10-03T08:04:34+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> 2018-08-28T10:40:56+00:00 ##submission.copyrightStatement##
