Characters of Chaquihua of unclear phylogenetic status. (1) Each tergalius
I–VII has no fibrillose lobe [see Ameletopsis/fg1 (4)]; narrow, with a short anal rib at proximal part of anal margin (unlike other
Ameletopsis/fg1) (photo (2) Larval cerci with secondary swimming setae [unlike Mirawara – see Ameletopsis/fg1 (5)]. (3) Imaginal and subimaginal paracercus is diminished, several
times shorter than cerci (photo
Plesiomorphies of
