Remarks. This new species is similar to T. (T.) athiasae Porath & Swirski , T. (T.) octogenipilus Kreiter, Tixier & Duso , T. (T.) pyri (Scheuten) , T. (T.) sirikariensis Stathakis, Kapaxidi & Papadoulis and T. (T.) tiliae (Oudemans) . Differences between Typhlodromus (T.) antakyaensis Stathakis & Döker n. sp. and the related species are given in Table 2 .

Etymology. The name of this new species is derived from the Antakya province where it was collected.

T. (T.) antakyaensis T. (T.) athiasae T. (T.) octogenipilus T. (T.) pyri T. (T.) sirikariensis Reference new species Porath & Tixier et al., 2010 Chant & Yoshida- Stathakis et al.,

Swirski, 1965 Shaul, 1987 2012 With this study, number of known phytoseiid species from Turkey reached 69. Among them, there are natural populations of commercially available phytoseiid mites such as Amblyseius swirskii Athias-Henriot , Iphiseius degenerans (Berlese) , Neoseiulus californicus (McGregor) , N. cucumeris (Oudemans) and Phytoseiulus persimilis Athias-Henriot. This and previous studies clearly showed that Turkey has great potential to supply new phytoseiid mites due to its geographical position (bridge between Asia and Europe) and its diverse flora of wild endemic plants which could serve as host for these predators. However, very little information is available about new species and/or newly recorded species regarding their food habits and biology. Further studies should be conducted to determine their possible use in biological control programs in Turkey.
