Caraboacarus stammeri Krczal, 1959

Material examined – Three large colonies were obtained under the elytra of ground beetles of Calosoma and Harpalus . The host beetles were collected by direct sampling in vicinity of Ziarat village, Gorgan, Golestan Province, 36.71° N, 54.48° E, and altitude 1511 m a.s.l., August 3, 2023, Shast-Kola, Baran-Koh waterfall, Gorgan, Golestan Province, 36.70° N, 54.36° E, and altitude 157 m a.s.l., June 11, 2023 and Alangdareh forest, 36.46° N, 54.26° E, and altitude 337 m a.s.l., July 27, 2023, coll. Vahid Rahiminejad. Furthermore, more than 30 specimens were extracted from various soil samples from A’ali-Kola, Zar’rin-Abad forests and agricultural and horticultural areas around Lak-Dasht village, Mazandaran province, during spring of 2023 were collected by E. Yahyapour.

World distribution and Host specificity – The species recorded from three continents (Asia, Europe and North America) and has least host specificity among all caraboacarid mites (Katlav et. al. 2015). Until now, various carabid beetles, including Amara spp. , Harpalus spp. , Calosoma spp. , Anisodactylus signatus (Panzer, 1796) , Diachromus germanus (Linnaeus, 1758) (Col.: Carabidae ) and Cicindela (Cylindera) germanica (Linnaeus, 1758) (Col.: Cicindelidae ) have been recorded as hosts for C. stammeri ( Rahiminejad et al. 2023) . Also, Trach and Khausov (2012) surprisingly reported C. stammeri under elytra and on the wings of Ablattaria laevigata (Fabricius, 1775) (Col.: Silphidae ) (Rahiminejad and Hajiqanbar 2020; Rahiminejad et al. 2023).
