Characters of Nathanella of unclear phylogenetic status. 


() Hind wings are lost. Non-unique apomorphy (see Index of characters [2.2.59]).

() Patella-tibial suture is absent on all legs of larva, subimago and imago. The same in Hagenulus/fg1 (see Index of characters [1.2.18], ibid. [2.2.82]).

() Tergalii I do not participate in respiratory movement: when tergalii II–VII make rhythmical respiratory movements, tergalii I are immovably projected backward. The same in some other taxa (see Index of characters [1.3.33]). In other respects all tergalii of pairs I–VII are similar [see ()].

() All imaginal and subimaginal claws are pointed. Non-unique apomorphy (see Index of characters [2.2.85]).
