Species Guides
12Eucyrtopogon is a of robber flies ( Asilidae) established by Curran in 1923. These small to medium-sized predatory flies are morphologically similar to the genus Comantella, with which they have been confused in field observations. The genus is poorly studied, with limited biological information available. -level relies on subtle morphological characters including antennal proportions and body hair coloration.

Identification
Eucyrtopogon closely resembles Comantella in general habitus—both are small to medium-sized Asilidae with long body hairs and a humpbacked thoracic profile.
