Valgothrombiinae
Valgothrombiinae is a of mites within the Trombidiidae, a group of large, often brightly colored predatory mites commonly known as velvet mites or rain bugs. Members of this subfamily are distinguished by particular morphological features of the gnathosoma and leg chaetotaxy. The group is relatively poorly known compared to other trombidiid subfamilies, with limited published information on their and .

Identification
Valgothrombiinae can be distinguished from other Trombidiidae (Trombidiinae and Eutrombidiinae) primarily by characteristics of the gnathosoma, including the structure of the palpal tibial claw and the arrangement of setae on the palps. The subfamily is also characterized by specific patterns of leg chaetotaxy, particularly on I and II. Detailed examination under compound microscopy is required for definitive identification.
Distribution
The has been recorded from the Palearctic region, with documented occurrences in Europe and parts of Asia. Specific distribution records are sparse and largely based on limited taxonomic revisions.

Taxonomic History
The Valgothrombiinae was established by Feider in 1955. It has undergone limited subsequent revision, and its circumscription remains based primarily on the original morphological criteria. The group is considered one of the smaller subfamilies within Trombidiidae in terms of described .
