As a first supplement to the list of the water mites (Acari, Hydrachnidia) fauna of Turkey compiled by Erman et al. (2010), a faunistic list of water mites from Turkey is presented based on published data after 2010. Including the new data, the total number of taxa recorded from Turkey reaches 335 species, in 62 genera and 25 families. The new synonym is established Trichothyas (Lundbladia) anatolica Boyacı & Gülle, 2014 = Dacothyas kandilliensis Oezkan & Bader, 1988. Furthermore, for each family, the number of species is given, both, for this study and totally.

New records of water mites from Iran and Turkey revealed by DNA barcoding are presented. DNA barcodes were recovered from 44 water mite specimens morphologically assigned to 18 species. The DNA barcoding data for the twelve species were uploaded into the BOLD database. One species of the Hygrobates longiporus-complex, H. thori Pešić & Smit sp. nov. is described as new for science and Hydrodroma persica Pešić & Saboori, 2012 is reported as new for Turkey. We propose to lower the taxonomic status of Hydrodroma golestanica to a subspecies of H. torrenticola, i.e. H. torrenticola golestanica nov. stat.

During the period from December 2003 to November 2004 a study has been held to examine the water quality and zooplankton of highly alkaline Lake Burdur. The lake showed thermal stratification between June and October. Six zooplankton taxa were determined, Hexarthra fennica, Brachionus plicatilis from Rotifera and Arctodiaptomus burduricus from Copepoda were the dominant species. Average zooplankton density was 399,074 ind.m -3 and they were 51% H. fennica, 9% B. plicatilis and 40% A. burduricus. In addition, vertical zooplankton distributions have been investigated in this study. Generally, zooplankton groups were concentrated between 5-20 m. However, rotifers and A. burduricus were determined to have the highest density at 5 and 15 m, respectively.

Eighty species of water mites belonging to 15 families were identified in the field surveys carried out between 2013-2016 within Burdur Province. The family represented by the largest number of species was Hygrobatidae, which includes 25% (20 species) of the identified species. In our study, distribution of the determined species to the families is as follows:

Description of a new Atractides species, Atractides reinhardi n. sp., from Burdur Province of Turkey is given. Water mites of the genus Atractides Koch, 1837 have been found in all biogeographical regions except for Australia and Antarctica, most of the 297 species described so far are known from Northern Hemisphere: 56 species have been found in the Oriental Region, 47 species have been found in the Afrotropical region, 32 and 27 species have been described from the Neotropical and Neartic regions, while 138 species (46% all described species) known from the Palaearctic and mainly the Mediterranean countries (Gerecke 2003; Pešić & Smit2011). Most species are found only in clean waters with well conserved substratum, thus they are probably sensitive to many forms of human impact (Gerecke 2003). With 29 species, the genus Atractides is among the most species rich genera of the water mite fauna of Turkey which has been insufficiently known (
