The subfamilies of Protoneuridae (Zygoptera)

The subfamilial classification of the Protoneuridae is reviewed. No clear-cut divisions are apparent between the 3 currently recognised subfamilies (the Caconeurinae, Disparoneurinae and Protoneurinae), based on an examination of adult morphology in representatives of 20 of the 23 genera. The Protoneuridae should be regarded as comprising a single subfamily.
