The species is also one of two in the genus that lacks the diterpene (-)-16 ?-hydroxykaurane, a diagnostic character trait that easily separates the species from most others in the genus.

Diagnostic characters : they are trees, with the flowers not involucrated, ovary superior, nine or fewer fertile stamens, anthers four-locular and nine tepals, and the fruit with cupules ( see illustration ).
33.
Collected specimens are 2.2 to 3.2 centimeters long . " D . vascoana " " is easily recognizable anatomically by the shape and colouration of its penis ", a main diagnostic character.
34.
A striking diagnostic character is the apophysis forming a pincer with the dorso-apical apophysis of coxa IV . Two of these species present neon green stripes on the mesotergum ( Kury, 2003b ), which is uncommon in this subfamily.
35.
He retained " A . " sect . " Eurylaema ", making no change to its circumscription, but discarded many of Bentham's diagnostic characters, retaining only the sterile anther and the shape of the style-end.

Goodrich did not give them ranks, and treated them exactly as if they had phylogenetic definitions, using neither contents nor diagnostic characters to decide whether a given animal should belong to Theropsida, Sauropsida, or something else once its phylogenetic position was agreed upon.
37.
The diagnostic characters for " Cathetosaurus " are : the pelvis is rotated anteriorly, such that the pubis projects posteroventrally, and the ischium projects posteriorly, lateroventrally projecting spurs in the neural spines of the last dorsals; posterior cervical and anterior dorsal diapophyses bearing an anterior projection lateral to the prezygapophysis.
38.
In their review of putative euparkeriids from China, Richard Butler and colleagues concluded that " Wangisuchus " is a " nomen dubium " at Archosauriformes indeterminate because its holotype lacked diagnostic characters, even though the thecodont tooth implantation pointed to a closer relationship to Archosauria than to " Proterosuchus ".
39.
Alberto Cobos " et alii " in 2010 noted that all the diagnostic characters of " Miragaia longicollum " are based on skeletal elements that are absent in the " Dacentrurus " holotype found in England in layers of about the same age, while all traits that can be compared are shared by both genera.

In 2009, N . Snegovaya & W . Starga synonymized this genus with " Phalangium ", on the grounds that the shape of the horn on the second segment of the male chelicera ( the only diagnostic character of the genus " Bactrophalangium " ) fits well within the range demonstrated by the rest of the genus " Phalangium ".
