A new larval record of Demicryptochironomus Lenz,1941 (Diptera, Chironomidae) for the Turkish fauna

Abstract

Seather, and Seatheria Jakson. These remained in the same tribe, and in the "Harnischia complex" (Şahin, 1984). Schadinia Lipina 1939 is being accepted as a junior synonym of Demicryptochironomus and it was entirely ignored in original descriptions (Yan et al., 2005). It resembles the species of the genera Cryptochironomus and Gillotia, owing to the double coloration in the dentalium of the labium plate, and the concave structure of the mentum originating from the protruding position of the lateral teeth in comparison with the median teeth. The numbers of the teeth on the labium plate for Cryptochironomus, Gillotia, and Demicryptochironomus are 5, 6, and 7, respectively. The antennae have 5, 6, and 7 articulations in parallel. It is a transitional form between the genera Gillotia, Cryptochironomus, and Demicryptochironomus (Şahin, 1984). Thirty-five species belonging to the genus Demicryptochironomus were described in the world, and among them, Demicryptochironomus vulneratus is a widely Abstract: Demicryptochironomus (Demicryptochironomus) vulneratus (Zetterstedt, 1838) was collected as a total of 4 individuals from the Garzan Brook, Batman Brook (Beşeri), and Tigris River (Hasankeyf) and recorded as a new chironomid larva species for the Turkish potamofauna. The species was identified morphologically under light microscope and photographed with a photomicroscope. In addition, the taxonomic features of the species were illustrated schematically with a scale.

Biodiversity of freshwater macroinvertebrates on Gökçeada Island (North Aegean Sea, Turkey)

“…Several studies have been carried out on benthic macroinvertebrates in freshwater ecosystems of Gökçeada (i.e. Şahin et al 1988;Balık & Ustaoğlu 1993;Özkan 2006;Çamur-Elipek & Aslan 2007;Özbek & Özkan 2017;Zeybek et al 2017;Aslan et al 2018;Odabaşı et al 2019). In addition to the records of benthic macroinvertebrates reported in the above studies, 51 taxa were recorded for the first time during this study.…”

“…Similar to the Aegean Islands, no complete documentation is available for freshwater invertebrates of Gökçeada and Bozcaada (the northeastern Aegean Sea). Several studies have been carried out to investigate specific taxa on Gökçeada, including Chironomidae, Ephemeroptera, Odonata, Amphipoda, Isopoda, Gastropoda, and Oligochaeta (Şahin et al 1988;Özkan 2006;Özbek & Özkan 2017;Zeybek et al 2017;Aslan et al 2018;Odabaşı et al 2019).…”
