Re-Description of the Female of Kampimodromus Langei Wainstein & Arutunjan (Acari: Phytoseiidae) Based on Normal and Abnormal Specimens, with the First Description of Its Male

Abstract

Kampimodromus langei Wainstein and Arutunjan (Acari: Phytoseiidae) is reported for the first time for the Turkish fauna. It is re-described and illustrated, based on normal and abnormal female specimens from material collected from Quercus cerris L. var. cerris (Fagaceae) trees in Samsun Province on the north coast of Turkey. In addition, the male is described for the first time in this study. Our examination of a series of female specimens of K. langei showed no remarkable differences compared to its original description and subsequent redescriptions. However, on both sides of a female specimen, we observed an additional dorsal seta inserted at the location of seta S1 known from other groups of Mesostigmata closely related to phytoseiid mites. The dorsal shield of the abnormal specimen is also illustrated and its setal measurements are provided. To the best of our knowledge of phytoseiids, the extra seta has been reported only for Typhlodromus (Typhlodromus) laurae Wainstein. The possibility of the more rearward location of anterior dorsal setae z6 and s6 which is known for some phytoseiid species, as well as the presence of extra seta/e on other species of phytoseiid mites, are also briefly discussed.
