1- Fuscuropoda(uropodid mite)
Urodinychidae is a of mites in the order Mesostigmata, belonging to the cohort Uropodina. The family includes at least five : Urodinychus, Uroobovella, Vinicoloraobovella, Mengzongella, and Ivoria. in this family are primarily soil-dwelling and have been documented from regions including Turkey, Ivory Coast, and parts of Europe. At least one species, Uroobovella marginata, exhibits complex maternal involving construction of protective chambers.

Identification
Urodinychidae can be distinguished from related uropodine by the structure of the gnathosoma and leg chaetotaxy. The family name refers to the characteristic two-clawed (di-onyx) structure of the pretarsus on the legs, combined with a tail-like (oura) region. Specific diagnostic features vary by ; detailed examination of idiosomal setation, sternal shield , and tritonymphal characteristics is required for accurate identification.
Habitat
Soil and litter . Uroobovella anatolica was collected from Eastern Anatolia, Turkey, though specific microhabitat details were not provided in available sources.
Distribution
Documented from Turkey (Eastern Anatolia, Eastern Black Sea Region), Ivory Coast, and parts of Europe including Norway and Sweden. Distribution records are sparse and likely reflect limited sampling effort rather than actual range limits.
Life Cycle
Females of at least one (Uroobovella marginata) construct protective chambers using substrate particles and excreted material before depositing eggs. Development includes deutonymphal and stages; deutonymphs have been described for some species.
Behavior
Pre-ovipositional substrate exploration and chamber construction observed in Uroobovella marginata. Females actively build protective structures for rather than depositing them directly on substrate.
Similar Taxa
- UropodidaeBoth belong to the superfamily Uropodoidea and share general uropodine body plan. Uropodidae typically have different pretarsal claw structure and gnathosomal ; Urodinychidae is distinguished by the two-clawed condition referenced in the family name.
- TrematuridaeBoth are uropodine with superficially similar habits. Trematuridae such as Trichouropoda ovalis have been studied alongside Urodinychidae species, but differ in idiosomal shield structure and leg chaetotaxy.

Etymology
name derived from Ancient Greek οὐρά (ourá, "tail"), δι- (di-, "two"), and ὄνυξ (ónux, "claw"), referring to the two-clawed pretarsal structure characteristic of the family.
Taxonomic note
The Elegansovella was established by Hirschmann in 1989, though recent sources indicate taxonomic revisions may be ongoing. The genus Ivoria was established in 2019 with a second described from Ivory Coast in 2021.
