Specimens examined. E Turkey, Tunceli Province, Pülümür District, Uzuntarla Village , leaf litter under Quercus sp., 25 May 2017 (two females). The specimens are deposited at the Institute of Zoology , Slovak Academy of Sciences , Bratislava.

Remarks. The species shows two atypical characters for Pachylaelaps , namely: (1) posterolateral areas of dorsal shield only with poroids gdS4 modified into a widely slit-like structures (gdZ1 uniform with other poroids on dorsum), (2) genu of legs I with only 12 instead of 13 setae (pd3 absent). Apart from these character states, the original description and illustrations given for this species by Costa (1971) do not require special amendment, except for seven pairs of r/R-setae on soft lateromarginal integument (in addition to eight pairs of opisthogastric setae on ventral soft integument) which were not specified and illustrated in his descriptive paper. Also tubular structures of the sperm induction system were not mentioned in the description but they are probably unsclerotised, rudimentary or absent because we were unable to detect them in our specimens. Pachylaelaps evansi is quite well recognisable species, described on the basis of both adult stages, and it has not been recorded for almost 50 years from its discovery in Israel. This is the first record of the species in Turkey.
