Isostictidae is a family of small to medium-sized damselflies restricted to Australia, New Caledonia, and New Guinea.[2] It contains 12 genera and more than 40 species.[3] Members of this family resemble species in the former threadtail family (Protoneuridae).
- Adult: The adults have a length of 15–40 mm. They have two antenodal crossveins, most postnodal crossveins aligned with crossveins behind them, quadrilateral cell almost rectangular, no supplementary intercalary longitudinal veins, and an anal vein fused with wing margin. Their antennae are seven-segmented.
- Larva: Larvae have a labial mask, with short flat palps and narrow palpal setae. Premental setae are variable, median lobe is shallowly cleft; caudal gills are saccular to triquetral and strongly nodate.[4]
