Abstract

The genus Valgothrombium Willmann, 1940 includes thirty one species. Seventeen of them are known postlarval forms and eleven of them are larval forms while three of them only are known both postlarval and larval forms. Valgothrombium alpinum Willmann, 1940 only recorded from Austria and Poland in the world. The mite specimens were collected from Bayburt and Erzincan Provinces, Turkey. The samples were caught with extraction in Berlese funnels. Examined material was preserved in 70% ethyl alcohol and cleaned in 9 % KOH solution. The specimens were fixed on slides in Hoyer’s medium. Measurements were taken and photographing made under a Leica DM 4000 microscope with phase contrast. The adults of Valgothrombium separable with differences of their dorsal setae, palps or crista metopica structures from each other. The examined species defined as adults of V. alpinum. Various characters of this species were photographed with a microscope. Morphological data provided based on adults of this species. Also, Turkish samples of this species were compared with European samples. In the present work, we aimed to contribute to the knowledge on species of Valgothrombium.
