Dicranota rivularis
Osten Sacken, 1860
Dicranota rivularis is a of in the , first described by Osten Sacken in 1860. It is a small to -sized with a Nearctic distribution centered in the eastern United States. The species is associated with riparian , as suggested by its specific epithet. Like other Pediciidae, it belongs to a group of crane flies formerly classified within . Very few observations exist in public databases, indicating it is either genuinely rare or underreported.

Identification
Separation from other Dicranota requires examination of male and details. The is distinguished from similar by features of the wing venation and larval preferences, though field identification to species level is generally not possible without specimen examination.
Habitat
Associated with streams and riparian zones, as indicated by the specific epithet 'rivularis' (Latin: of brooks or streams). of typically inhabit moist terrestrial environments near water, including saturated soils and mossy stream banks.
Distribution
Nearctic: eastern United States from New Hampshire south to Virginia.

More Details
Taxonomic History
was elevated from status within based on phylogenetic and morphological studies. Dicranota rivularis was described in the 19th century and has received limited modern taxonomic attention.
Data Deficiency
Only two observations recorded in iNaturalist as of source date, and GBIF distribution records are sparse. This likely reflects genuine rarity, specificity, or undercollection rather than absence.
