The Mesozoic chironomid genus Jurochlus Kalugina, 1985, known only as pupae, is reviewed. Four new species of Jurochlus are described from the Upper Jurassic and Lower Cretaceous deposits of Mongolia, viz. J. trivittatus sp. nov., J. limbatus sp. nov., J. lineatus sp. nov. (Shar Teg, J3) and J. adustus sp. nov. (Khutel Khara, J3/K1). Both previously described species, J. sibiricus Kalugina, 198...

Two new taxa of gut fungi within order Harpellales (Kickxellomycotina) are described from a stream in the Tianshan Mountains in northwestern China. These include the new genus and species, Sinotrichium chironomidarum J. Wang, S.Q. Xu & Strongman, and the new species, Stachylina tianensis J. Wang, S.Q. Xu & Strongman, both living in the guts of aquatic chironomid larvae. We also extend the geogr...

The larva, pupa and male of a new Neotropical chironomid species, Ablabesmyia tucuxi Neubern et Fusari sp. n., are described and illustrated. The larvae were found in freshwater sponge colonies of Drulia uruguayensis Bonetto et Ezcurra de Drago, 1968 and Oncosclera spinifera (Bonetto et Ezcurra de Drago, 1973) in Brazilian savanna streams. The morphological characteristics of the larval head an...

Abstract The taxonomic composition, structure, and spatial distribution of zoobenthos have been studied in 25 water bodies the Arctic tundra. Eight types thermokarst bodies, representing stages succession cycle, identified for central Yamal Peninsula. Water initial cycle are located on hills, middle at edge valleys, latest valleys. In total, 161 species found; their abundance diversity vary wit...

Abstract Here we provide the first chironomid record and associated summer air-temperature (T VII ) reconstruction between ca. 16,800–9100 cal yr BP from Lake Saint Anne (SZA), situated in Eastern Carpathians. SZA was formed by youngest volcanic eruption of Ciomadul volcano at 29,600 BP. Our main goals this study are to test whether warming after Heinrich event 1 (H1; 16,200 BP) had similar amp...
