Male. Unknown

Type material. Holotype female and nine paratype females, Karaisali , Adana Province, on young seedlings of Quercus cerris  ( Fagaceae  ), 21 June 2015  ; one female paratype, same location on Arbutus unedo  ( Ericaceae  ), 23 April 2016 (37°14'34"N, 35°00'09"E, 242 metres above sea level). 

Etymology. The name of the new species karaisaliensis  is derived from Karaisali municipality where it was found.

Depository. The holotype female and nine paratype females are deposited in the mite collection of the Acarology Laboratory , Department of Plant Protection, Çukurova University, Adana, Turkey  . One female paratype will also be deposited in the Natural History Museum , London, UK  .

from 11 specimens; b from Livshitz & Kuznetsov, 1972; c from Kolođochka, 1978; đ from Ke & Xin, 1983; e from Rahmani et al., 2010; f from Beglyarov, 1981. The lower anđ upper limits were calculateđ using the abacus proposeđ by Tixier, 2012. *Contrary to Livshitz & Kuznetsov, 1972, Papađoulis et al. 2009 đescribeđ setae StIV anđ Z5 as subequal in length; this reason the lower anđ upper limits are not calculateđ for StIV for commenticius  .

Remarks. This new species is similar to T. (A.) commenticius Livshitz & Kuznetsov, 1972  , T. (A.) inopinatus ( Wainstein, 1975)  , T. (A.) macrum Ke & Xin, 1983  , T. (A.) recki Wainstein, 1958  , and T. (A.) repens ( Beglyarov, 1981)  by having three pairs of solenostomes on the dorsal shield, two pairs of setae on sternal shield, four pairs of pre-anal setae, pre-anal pores present and peritreme associated with setae j3 or z2. Differences between Typhlodromus (Anthoseius) karaisaliensis  and related species are given in Table 2.

When compared with related species, great majority of dorsal setae are longer in the new species. For comparison of the setal lengths, the abacus proposed by Tixier (2012) was applied to the measurements of the five other species to calculate the lower and the upper limits. The non-overlap 95% confidence limits with the measurements of the new species suggested that this species is different from the others.

Most of the dorsal setal measurements are missing in the original description of T. (A.) repens  which seems more close to the new species. However, in the new species, measurements of setae z2, Z5 and StIV are out of the range calculated using the abacus. In addition, peritreme of the new species is longer than that of T. (A.) repens  . Furthermore, Beglyarov (1981) stated that the macrosetae StIV reached and well past the dorsal slit organ, while it does not reach to that organ in the new species. In addition, Z5 and JV5 are almost subequal in length, (69 and 65, respectively) in the new species. Beglyarov (1981) did not measure JV5 and not include scale bars in the drawings. However, the length of JV5 (probably 24–30?) seem to be almost half the length of Z5 which is only 48 in length. According to the original description, the ventrianal shield of T. (A.) repens  has sharp edges at the level of JV2. In the description, T. (A.) commenticius  and T. (A.) repens  were separated based on the shape of ventrianal shield which is more close to that of T. (A.) commenticius  in the new species (having rounded edges instead of sharp edges). In addition, only seta Z5 is serrated in T. (A.) repens  while both setae Z4 and Z5 are serrated in the new species. It should also be noted that this new species is also seems to be close to T. (A.) kazachstanicus Wainstein, 1958  which is known for the Turkish fauna. However, it is distinctly different based on both discrete and continuous morphological characters. The new species can be separated from T. (A.) kazachstanicus  by having preanal pores, longer peritreme, sharp and shorter (almost 35%) macrosetae StIV and at least 25% longer j3, j5, j6, z3, z4, Z4, s4, s6, S2, S4 and JV5 setae.
