Autapomorphies of Nathanella. () Larva is adapted for crawling by wet rocks of waterfalls (photo): ... () ... Labrum without median incision ... [see Atalophleboculata (2)] ... 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]). Plesiomorphies of Nathanella. ... |
