Rheocricotopus (Rheocricotopus) reduncusoides 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 Parametriocnemus hamatus (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 Rheocricotopus Thienemann and Harnisch and Parametriocnemus Goetghebuer, and present a key to the Nearctic adult males of these genera.

My friend and colleague Donald Herbert Deshon Edward died in June 2018 at the age of 85 following a decline in health in the previous months. Thus ended a long career entirely based at the University of Western Australia on the banks of the Swan River in Perth. Don Edward was a versatile aquatic biologist who had a particular affection for the stranger life histories amongst the many chironomids that surrounded him in the south-west of Western Australia. Although quiet on the publication front in his later years (Fig. 2E), he continued to sort samples from projects, including many in Western Australia and from Papua New

Here we report the occurrence of Heterotrissocladius (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.

Cricotopus (Cricotopus) latellai 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 C. latellai sp. n. as male and female adults, pupal exuviae and last instar larvae. The diagnosis of the Cricotopus tremulus-group is supplemented with additional characters in the male adult and pupal exuviae. Cricotopus latellai sp. n. keys near C. mantetanus Moubayed-Breil, 2016 and C. storozhenkoi Makarchenko & Makarchenko, 2016. Geographical distribution of C. latellai 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.

Adult female Trichochilus lacteipennis 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 T. lacteipennis are parasitic on Elliptio complanata at this site and probably additional unionid mussel species elsewhere. Based on our dissections of parasitized mussels and previous reports, it appears T. lacteipennis 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.

We report on 2 first records of Chironomidae for Ontario, Rheosmittia spinicornis (Brundin, 1956) and Sublettea coffmani (Roback 1975), and confirm a previous record of Odontomesa fulva (Kieffer 1919) from Ontario. Specimens of S. coffmani have been only reported from New Brunswick whereas R. spinicornis has records from northern, western and central provinces and territories. Reports of O. fulva were not con-firmed in Ontario. Here we report its occurrence for the second time in south central Ontario, confirming its occurrence within the province.
