A new Atractides Koch (Acari: Hydrachnidia, Hygrobatidae) species from southwestern Turkey.

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 (Erman et al. 2010; Aşçı et al. 2011; Gülle et al. 2010; Esen et al. 2013; Esen & Erman 2013). Among the material collected during an extensive survey of the water mite fauna of Burdur Province in southwestern Turkey in 2013–2014 period, one Atractides species new for science is described. Water mites were collected by hand netting and sorted on the spot from the living material, preserved in Koenike’s fluid and dissected for slide mounting in Hoyer’s fluid. All measurements are given in μm. For a detailed description and discussion of the characteristics of the genus Atractides and a detailed methodological introduction, see Gerecke (2003). The following abbreviations are used: Ac= acetabulum, asl. = above sea level, Cx–I = first coxae, dL = dorsal length, H = height, L = length, I–L–6 = Leg 1, sixth segment, mL= median lengt, P–1 = palp, first segment, S–1 = large proximal ventral seta at I–L–5, S–2 = large distal ventral seta at I–L–5, Vgl = ventroglandulare, vL = ventral length, W = width.
