Diagnosis. Nymph. Lestagella nymphs can be distinguished from other Teloganodidae by the following combination of characters: a well-developed marginal fringe of setae on the head (Fig. 2 c–e), spatulate setae on margin of prothorax, simple filamentous gills present on abdominal segment I, lamellate gills on segments II–IV with fully operculate gill on segment II, tibia lined with a single row of setae on the antero-dorsal surface, tarsal claw with well-developed subapical denticle, other denticles small. Abdominal segments with moderately developed posterolateral processes that are slightly separated from the base of the following segment, three caudal filaments with lateral, hair-like setae and a subequal median caudal filament.

Imago. Lestagella adults can be distinguished from other Teloganodidae by the combination of the following characters: three caudal filaments, forewings with a relatively short, detached iMP and the presence of gill socket vestiges on abdominal segments II–IV.
