A contribution to the knowledge of Coccalicus clavatus Willmann, 1952 (Trombidiformes, Iolinidae) new to Asian fauna.

The iolinid mite Coccalicus clavatus Willmann, 1952 was collected during a survey from the soil of Gilanegharb, Kermanshah, Iran in 2022. This species was first described in the family Alycidae by Willmann in 1952 and then André and Uusitalo transferred it to the family Iolinidae in 2006, accompanied by transferring species from the genus Paratydaeolus to the genus Coccalicus. Some challenges about species characters of this mite are discussed in this paper and the synonymy of C. lukoschusi and C. clavatus is proposed. The genus consists of 12 species with clavate trichobothria, and is related to various habitats like soil, stored products, under barks, on leaves of different plants, and on birds. They have been reported from Europe, Antarctica and North America and this is the first record of the Coccalicus mites from Asia. [ABSTRACT FROM AUTHOR]
