Identification
Distinguished from related limoniid by the combination of: 14 flagellomeres (not 16); narrow pronotum with lateral lobes; presence of dm in wing; 3-4 branches of media reaching margin; and male genitalia with gonostylus bearing a long curved spine. Subgenus Calolimnophila differs in wing pattern and genitalia details. -level identification requires examination of male genitalia; Chinese species can be separated using the key in Zhang et al. (2025).
