12d we have shown the common ancestor of Canrightia and Chloranthaceae as having three free carpels and the syncarpous gynoecium of Canrightia as an autapomorphy
(in terms of parsimony this is equivocal, since the syncarpy character is undefined in unicarpellate taxa).
The haustellum is the only suggested autapomorphy
for adult Trichoptera  and we propose that the structure in the holotype of A.
These depressions are also observed in Lusotitan atalaiensis lectotype, and might represent an autapomorphy
of this taxon.
Reports differ on whether or not the inner surface of the proventriculus is toothed, and on what counts as teeth: one study claimed that absence of proventricular dentition is an autapomorphy
of the Euphasmatodea (Tilgner et al.
Within the Cryphocricinae one autapomorphy
(66) is indicated for Ambrysus occidentalis.
Crotaphytus grismeri is not represented here, as this species has the unique condition of a predominantly closed Meckel's groove (an autapomorphy
of the species; McGuire, 1996), which was not seen in any dentary from Fowlkes Cave.
One character that is possibly an autapomorphy
loftini may be parsimoniously considered an autapomorphy
. In addition to R.
In snakes and lacertilians, exclusive paired structures developed along the lateral wall of the cloaca - the hemipenis, regarded as an autapomorphy
of that group (RIEPPEL, 2000; POUGH et al., 2003).
A reduced paraconid in the second lower premolar is an autapomorphy
of Brachypotherium (Antoine, 2002).
quekettiana complex indicates that they too will have spermatophores with scale-like spines, suggesting that this is an autapomorphy
for this smaller-shelled clade.
