Ereynetinae
Genus Guides
3Ereynetinae is a of mites within the Ereynetidae, order Trombidiformes. These are small arachnids belonging to the diverse group of prostigmatic mites. The subfamily is distinguished by particular morphological features of the gnathosoma and idiosoma. Relatively few observations exist in public databases, suggesting either cryptic habits or limited survey effort.

Identification
Separation from other ereynetid relies on characters of the gnathosoma, particularly the cheliceral bases and palpal setation. The subfamily Ereynetinae is distinguished from Rudniellinae by differences in the structure of the subcapitulum and the arrangement of idiosomal setae. Detailed microscopic examination is required for definitive identification.

Appearance
Mites of this are minute, generally less than 1 mm in length. The body is divided into the gnathosoma (mouthpart-bearing region) and the idiosoma (main body). Key diagnostic features include the structure of the and the arrangement of setae on the idiosoma. The is typically soft and unornamented or weakly sclerotized.
Distribution
Records are sparse and scattered. Observations in iNaturalist suggest presence in North America, but the actual range is likely broader and poorly documented due to the cryptic nature of these mites and limited identification.

Taxonomic note
The Ereynetidae and its have undergone taxonomic revision. Some authorities have questioned the monophyly of traditional groupings. The subfamily Ereynetinae as currently constituted may not represent a natural evolutionary lineage pending further phylogenetic study.
