Poduromorpha
Encyclopedia
The order
Poduromorpha is one of the three main groups of springtail
s (Collembola), tiny hexapods
related to insect
s. This group was formerly treated as a superfamily
Poduroidea.
They can be best distinguished from the other springtail groups by their body shape. The Symphypleona
are very round animals, almost spherical. The Entomobryomorpha
contain the slimmest springtails, some with long and some with short legs and antenna
e, but always with a very slender body. The Poduromorpha, by contrast, always have short legs and a plump body, but more oval in shape than the Symphypleona.
(then called Entomobryoidea) in a group called "Arthropleona", but this has more recently turned out to be paraphyletic. Actually the Entomobryomorpha, the Poduromorpha, and the third springtaill lineage – the Symphypleona
– are equally distinct from each other. Their treatment at equal taxonomic rank
reflects this. Their rank has also varied a bit. When the springtails were still believed to be an order of insects, the "Arthropleona" and the Symphypleona were treated as suborders.

Order (biology)
In scientific classification used in biology, the order is# a taxonomic rank used in the classification of organisms. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family...
