Identification
Identification of Curtonotum relies heavily on male genitalic characters, particularly the phallus viewed from right and left lateral perspectives. The fifth sternite and hypandrium of the male are also diagnostic. Species-level identification requires examination of and structure, , and wing venation patterns. The can be distinguished from related genera in Curtonotidae by features of the male genitalia and overall body structure.
