Brevitentoria is an infraorder of Trichoptera (caddisflies) within the suborder Integripalpia, established by Weaver in 1984. It comprises of case-making caddisflies characterized by shortened, reduced in the skeleton. A comprehensive inventory in Espírito Santo State, Brazil documented 40 from 3,420 adult specimens, including three newly described species in the Phylloicus, Helicopsyche (Feropsyche), and Marilia. The estimated total for this infraorder in the state is approximately 72 species.

Identification
distinguished from other Integripalpia by reduced —shortened internal skeleton structures that support the brain and musculature. This morphological reduction in the tentorium is the defining synapomorphy of the infraorder. Larval cases are typically constructed from sand grains, plant material, or silk, depending on .
