Scientists of Tyumen state University (TSU), together with colleagues from the Institute of Zoology of the Academy of Sciences opened three new species of mites living on scarab beetles in Brazil. The results of the study were published in the scientific journal «Zootaxa».

Brazil remains for scientists and taxonomists as one of the most attractive places on the planet where the wildlife still hides many secrets. The result of the next expedition Russian acarologia (acarology – the science of grip) with the aim of the study of the fauna of Brazil was the description of the three previously known to science, species of mites of a cohort Heterostigmata: Athyreacarus primitivus, Pavania neotropica is and Spatulaphorus brasiliensis.

Ticks were collected from dung beetles collected in the Brazilian States of Mato Grosso and Amazonas with the help of special traps. A detailed study of new types conducted in the laboratory of Tyumen state University, where he was made photomicrographs of mites caught male and female specimens.
The diversity of mites in the world, according to some estimates, to reach 10 million views. Just 54 thousand of them are known to scientists. However, as says a leading specialist aerolog of TSU Alexander Khaustov, not all mites are parasites. There are other types of relationships between living organisms, including foresee – using other organisms as a means of transportation.

Ticks live in different environments: soil, water and on plants. Some of them are poisonous. «Mites of certain types of produce very strong toxins-alkaloids. Living in the tropics, the types of wood frogs accumulate in our skin these substances. It makes the frogs themselves poisonous to other animals» – gives the example of TSU Vice-rector for science Andrei Tolstikov.

Scientists now very important description of a new species of mites in tropical regions of the world where due to the reduction of natural habitat loss of biodiversity is the most rapidly.

Over the past five years scientists acarology of TSU for the first time science has described over 600 new species of microscopic mites. Studies are being conducted worldwide in the most different corners of the world: South and Central America, in South Africa, New Zealand, the Philippines and Vietnam. In September 2017 the TSU hosted the international school of young scientists dedicated to soil acarology.
