Tetramerotarsata Liberevenata Turbanoculata
Anteropatellata Baetovectata Baetungulata - Guajirolus/g1)
Nomen hierarchicum: Guajirolus/g21 [g:1985] (incl. Chane)
In circumscription fits:
Nominal taxon included: Chane/g [g:2003]
() 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.
() 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.
() On each claw [with single inner-anterior row of denticles – see Baetungulata (1)] the most distal denticle is much larger than others and located at midline of inner side of the claw, while other denticles form a regular row anteriad of this midline; the most distal denticle of this anterior row (i.e. denticle located just proximad of the largest denticle) is thinner than others, relatively long and arched (Falcao & Salles & Hamada 2011: Fig.79, 107).
