Autapomorphies of Dabulamanzia.  

()

() Larval claw with 1 row of denticles, which is anterior one among two initial rows [see Tetramerotarsata (11)]. The same in some other taxa (see Index of characters [1.2.21]).

Plesiomorphies and characters of Dabulamanzia of unclear phylogenetic status. 

()  

() In larva outer-apical spatulate seta present on fore tibia, absent on middle and hind tibiae (see Index of characters [1.2.17]).

() First tergalius is narrower than others, petiolate and paddle-shaped (see Index of characters [1.3.33]).

() Tergalii are able to make rhythmical respiratory vibration (see Index of characters [1.3.30]).

Plesiomorphies of Dabulamanzia. 

In larva, subimago and imago of both sexes patella-tibial suture is present on middle and hind legs, absent on fore legs (unlike Anteropatellata) (see Index of characters [1.2.18], ibid. [2.2.78.1], [2.2.82]).

Fore wings with no more than one marginal intercalary in each space (unlike Baetovectata) [see Liberevenata (2)] (Index of characters [2.2.55]). 

Lateral margins of all abdominal segments lack spines or denticles (unlike Cloeon/fg1 and Anafroptilum).

Before moult from larva to subimago, subimaginal gonostyli are bent under larval cuticle in «Cloeon-type» pose, i.e. with 2nd segments directed laterally. The same in most other Protopatellata and Anteropatellata-non-Baetovectata (see Index of characters [2.3.9]).
