گزارش جدید کنه‌هایی از خانواده‌های Chyzeriidae، Microtrombidiidaeو Erythraeidae (Acari: Parasitengona) از ایران

Terrestrial Parasitengona mites are ectoparasite of arthropods in larval stage. Deutonymphs and adults are usually predators on other arthropods. The dispersion of this group is mostly in the larval stage, which are transferred to other places by connecting to hosts belonging to different orders of insects. During 2021–2024, to identify terrestrial Parasitengona mites in Sistan and Baluchestan province, samples were taken from different regions and ecosystems of the province. Due to the difference in the habitats and host range of this group, in this study used several sampling methods including: direct host collecting, pitfall trap, light trap and tubular trap. It should be mentioned that the tubular trap was also used for the first time as a sampling method in the science of Acarology, and good results were obtained. The specimens were cleared in lactophenol solution and mounted on microscope slides in Hoyer’s medium. The slides were placed in an oven at 45°C for two weeks. During this study, the genera Perumaropta Haitlinger, 1999 (Chyzeriidae: Chyzeriidae) associated with Gryllidae (Orthoptera) and Scarabaeidae (Coleoptera) and Hexathrombium Cooreman, 1944 (Microtrombidiidae: Eutrombidiinae) associated with Cicindelidae (Coleoptera) and Orthoptera and the subgenus Leptus (Amaroptus) Haitlinger, 2000 (Erythraeidae: Leptinae) on Acrididae (Orthoptera) were collected and identified, which are new report for Iran and the species are new for the science. Also, two new species from Pteridopus Newell and Vercammen-Grandjean, 1964 (Chyzeriidae: Pteridopinae) collected by tubular trap (off host) and Eutrombidium Verdun, 1909 (Microtrombidiidae: Eutrombidiinae) were collected associated with Gryllidae (Orthoptera).
