CLADOENDESIS OF EPHEMEROPTERA
Tetramerotarsata Liberevenata Turbanoculata
Anteropatellata Baetovectata Baetungulata Labiobaetis/f1=Guajirolus/g1 - Guajirolus/g2)

In circumscription fits:
Autapomorphies of Guajirolus/g1.
() On both mandibles, inner margin between kinetodontium and mola is heavily sclerotized and forms a sharp projection just proximad of prostheca, so that base of prostheca is inserted into a sharp incision between base of kinetodontium and this projection. Unique apomorphy.
() On maxillary palp [2-segmented – see Baetungulata (3)], the first segment has a transverse fold, which divides it into two parts superficially resembling segments (but its muscles – adductor and abductor of second segment – pass through both these parts). Because of this fold on the first segment, the palp looks as three-segmented. The same in Pseudopannota/g2 (see Index of characters [1.1.42]).
() On labial palp, inner projection of second segment is enlarged: in Guajirolus/g2 it is very long and wide, in Chane it is narrow and unusually long.
() On each claw, row of denticles [single – see Baetungulata (1)] has distalmost denticle much larger than others. Non-unique apomorphy (see Index of characters [1.2.21]), but unusual for Turbanoculata.
