Echinacea Order Echinoida Family Echinidae Genus Psammechinus AGASSIZ y DESOR, 1846 Psammechinus affinis FUCHS P1.
Stomopneustes variolaris has long been placed in the superorder
Stirodonta because of the structure of its Aristotle's lantern: keeled teeth, small epiphyses, and an open foramen magnum over each tooth (Jackson, 1912).
Although rabies has not been identified to date in Tamandua tetradactyla, we analyzed mtDNA from this species because it was the only species from the superorder
Xenarthra and, in addition to providing an opportunity to analyze genetic material from this species threatened with extinction, it allowed us to evaluate the primers MTL-PRO2 and CCR-DR1  more thoroughly.
Rotifera of the Superorder
Monogononta recorded from Neotropis.
The first step distinguishes between the characters with states that are conserved across Theria, those that are conserved within the Metatheria (but differ from the Eutheria), those that are conserved within the Eutheria (and are different from the Metatheria), and those that vary, either across all Theria or within one of the superorders
The flavonoids and triterpenoids were selected as chemosystematic markers for this purpose, due to their general occurrence and diversification in this superorder
Palynological data on the systematics of the superorder
correct, typified names at the ranks of order, superorder
being part of the superorder
Commelinanae, and finally, they are one of
Most recently, Takhtajan (1997) elevated the family to the rank of monotypic order (Paracryphiales) but listed it next to Theales in Thorne's superorder
However, results of Mantel tests between matrices at the rank of subclass and superorder
are discussed; they were all significant, and could possibly be correctly interpreted.
The bulk of the orders that used to fall in the Asteridae now fall under the subclass Lamiidae, which includes the superorder
Gentiananae--composed of the orders Gentianales and Oleales (this later being monofamilial).
