As related to the hyobranchial skeleton, the the basihyal cartilage was not found in any Urotrygon species, which is considered as a synapomorphy
2014), coupled to the difficulty in the morphological identification of fish parasites which are frequently microscopically sized and characterized by a simple morphology, hindering the obtaining of synapomorphy
for phylogenetic reconstructions (Luton et al.
However, presently there is no synapomorphy
supporting the inclusion of P.
A marked anterior displacement of the neural arch in anterior and middle caudals is considered a synapomorphy
of Titanosauriformes (Salgado et al.
The presence of two papillae per subsidiary cell herein supports the assumption of this feature as a synapomorphy

This was considered a putative synapomorphy
and was recognized as the main character to delimitate species, together with characters of male genitalia.
The manus is distinctly smaller than the pes, however, and this appears to be a synapomorphy
Papp stated that 'broad, setose fronto-orbital plates' were 'a strong synapomorphy
of the tribe'; we are not entirely sure of his meaning here, but Proteaphila does not have conspicuously broad or setulose fronto-orbital plates.
The sperm duct gland: a visceral synapomorphy

2005) proposed that distinctive donut-like trichome base scars that often encompass more than one epidermal cell represented a synapomorphy
linking Platanaceae and Proteaceae.
2) shared synapomorphy
having anteriorly convex margin of paraclypei.
This character may still stand as a synapomorphy
shared between Ceratophryidae and Beelzebufo species; however, present analysis indicates that it may be better considered as a homoplasy.
