Emblyna uintana
(Chamberlin, 1919)
Emblyna uintana is a of mesh-web weaver in the Dictynidae, first described by Chamberlin in 1919. It belongs to a of small spiders that construct irregular, tangled webs. The species is known from the western United States, with records from Utah and surrounding regions. Like other dictynids, it is a small-bodied spider with relatively simple web architecture compared to -weaving relatives.

Identification
Distinguishing E. uintana from requires examination of genitalic structures, particularly male and female . The name 'uintana' references the Uinta Mountains/region, suggesting geographic association with that area. Separation from other western North Emblyna species depends on subtle differences in sclerotized reproductive structures visible only under magnification. Field identification to species is not reliable without microscopic examination.
Habitat
Specific associations for E. uintana are not documented. Based on patterns and collection locality (Utah/western USA), likely occurs in montane or semi-arid environments with sufficient vegetation or rock crevices for web placement.
Distribution
Known from the western United States. The specific epithet and original description suggest association with the Uinta region of Utah. GBIF records indicate multiple occurrences within USA, consistent with a regional western distribution.
Behavior
As a dictynid, constructs irregular mesh-like webs for capture. Web architecture consists of tangled strands rather than geometric patterns. Specific behavioral observations for E. uintana have not been published.
Ecological Role
Functions as a small in terrestrial , capturing small flying and crawling in its web. Serves as for larger , birds, and other vertebrates.
Human Relevance
No documented economic or medical significance. Too small to be of concern to humans; not known to bite.
Similar Taxa

Taxonomic Note
Chamberlin's 1919 description established this based on material from Utah. The specific epithet 'uintana' derives from the Uinta Mountains or Uinta Basin region, a major geographic feature of northeastern Utah.
