Description

C. longicornis is a long-legged, green fly with an iridescent exoskeleton. Like other flies in the Condylostylus genus, it holds its wings diagonally while at rest.{{Cite web |title=Field/Photo ID for Flies - Key to Western Sciapodinae |url=https://sites.google.com/view/flyguide/species-guides/dolichopodidae/sciapodinae/key-to-western-sciapodinae |access-date=2023-10-06 |website=sites.google.com |language=en-US}} C. longicornis can be differentiated by dark femora, a brown fore tibia, and non-uniform bristles along the mid- and fore-tibiae. Males of the species have a sparse row of bristles along the mid tibia and basitarsus, and females will always have a yellow mid-tibia.{{Cite web |title=Species Condylostylus longicornis |url=https://bugguide.net/node/view/481318 |access-date=2023-10-06 |website=bugguide.net}}
