  Wikipedia: Shrimp
Examples are the mantis shrimps and the opposum or mysid shrimps, both of which belong to the same class (Malacostraca) as the true shrimps, but constitute two different orderss within it, the Stomatopoda and the Mysidacea.
Also, debates on the taxonomy of the decapods continues, and not all authorities recognise Natantia as a valid grouping, while some would place infraorders or superfamilies beneath it.
In this scheme, the members of the Pleocyemate infraorder Caridea are regarded as the "true shrimps", while the members of the Dendrobranchiate infraorder Penaeoida are referred to as "penaeid shrimps".

The infraorder is supported by a few synapomorphies showing a high level of homoplasy, such as the articulation of the larval mandibles and abbreviation of the costal vein in the adult wing, (139, 190), and has been criticized on these grounds (60).
The relationships of the infraorders of lower Diptera, lower Brachycera, and the families of lower Cyclorrhapha are obvious examples.
The lower Brachycera (Orthorrhapha) are represented on the diagram by the infraorders Stratiomyomorpha, Xylophagomorpha, and Tabanomorpha and the superfamilies Nemestrinoidea, Asiloidea, and Empidoidea.

 FLEAS: Taxonomy and Phylogeny
The anterior arm of the 1st thoracic link-plate, the outer lobe of the 2nd thoracic link-plate, and the metathoracic squamulum are absent.
Fleas of these infraorders possess a squamulum (except in the family Xiphiopsyllidae); the ventral margin of the pronotum is divided into 2 lobes, the hind lobe sometimes being secondarily reduced.
In fleas belonging to the infraorders Hystrichopsyllomorpha and Pygiopsyllomorpha, the spinelets are sometimes present on tergites I-V, being located on the straight margin of the metanotum and abdominal tergites.

 All about lobsters
The infraorder Astacidea contains three superfamilies: the Nephropoidea (the commercially important marine lobsters) and the Astacoidea and Parastacoidea (freshwater crayfishes of the northern and southern hemispheres, respectively).
The infraorder Thalassinidea consists of only one superfamily, the Thalassinoidea, which are used as both food and bait.
Lobsters and crayfishes of the infraorder Astacidea are distinguishable from other lobsters because they bear pincers (or chelae) on the first three pairs of legs.

 Crab - MSN Encarta
Crab, common name for any arthropod of two crustacean groups, or infraorders: hermit crabs and allies (about 1,400 species) and true crabs (about 4,500 species).
Both of these distinct groups have a similar body shape characterized by a reduced abdomen and an enlarged and broadened anterior (front) portion of the body.
Hermit crabs and their allies make up the infraorder Anomura.

The living Strepsirhini are sometimes divided into two infraorders: the Lemuriformes, for the Lemuridae, Indriidae, and Daubentoniidae; and the Lorisiformes, for the Lorisidae.
The genera Microcebus, Mirza, Cheirogaleus, Allocebus, and Phaner, all formerly assigned to the Lemuridae, are now placed in the family Cheirogaleidae, and this family is considered to be associated with the Lorisidae (Tattersall 1982; Tattersall and Schwartz 1975).
The sequence of haplorhine families presented here follows that of Hershkovitz (1977), who divided the living members of this group into three infraorders: Tarsii, for the tarsiers; Platyrrhini, for the New World monkeys; and Catarrhini, for the Old World monkeys, the apes, and humans.

 Plant Bug :: Planetary Biodiversity Inventory
The terminal groupings with the Heteroptera are referred to as infraorders by most modern authors, a terminology which we shall follow.
The first documented synapomorphy scheme for the 7 heteropteran infraorders was that of Schuh (1979).
Features of this seldom seen group of true bugs have not figured prominently–if at all–in many classificatory schemes of the Heteroptera, or their morphology was incompletely appreciated, leading to their placement with the Reduviidae, the latter being members of the infraorder Cimicomorpha.

 The Primates: Prosimians: Part II
The fact that they are nocturnal has allowed them to largely avoid direct competition with the monkeys and apes, which are all diurnal in the Old World.
An infraorder is a higher, more inclusive classification category than a family.
Their classification is problematical because they have what appear to be a blend of prosimian and monkey traits, but they are genetically different from both groups of primates.

 Heteroptera - Wikipedia, the free encyclopedia
The infraorders Gerromorpha and Nepomorpha contain most of the aquatic and semi-aquatic members of the suborder, while nearly all of the remaining groups that are common and familiar are in the infraorders Cimicomorpha and Pentatomomorpha.
The use of the name "Heteroptera" has a long history at the rank of order, dating back to Latreille, 1810, and it is only recently that it has been relegated to a subsidiary rank within a larger definition of Hemiptera, so many reference works still include it as an order.
The only difference between Heteroptera and Prosorrhyncha is that the latter includes the family Peloridiidae, which is a tiny relictual group that is in its own superfamily and infraorder.

 FIMOL1
Within the Tricladida, three infraorders usually have been recognized: Maricola (marine planarians), Paludicola (freshwater planarians) and Terricola (land planarians) (reviewed in Sluys 1989), to which a new one, the Cavernicola was further added (Sluys 1990).
Relationships within the infraorders have only been considered in detail within the Paludicola, in which three families are currently recognized: the Dugesiidae Ball, 1974, the Planariidae Stimpson, 1857, and the Dendrocoelidae Hallez, 1892.
Therefore, it was suggested that the infraorders Terricola and Paludicola are redundant and should be replaced by a new taxon, the Continenticola (Carranza et al 1998a).

Serpentes is the suborder of reptiles commonly known as snakes.
There are two infraorders of living snakes: Alethinophidia (with the superfamilies: Henophidia and Xenophidia) and Scolecophidia (with the superfamily Typhlopoidea).
These include moving of families to different infraorders, merging or splitting of the infraorders and merging and splitting of the families.

 FLYTREE Phylogeny, the story so far - p. 2
Although molecular data has been used increasingly to reconstruct Dipteran phylogenies, most published analyses to date have focussed on questions at a lower-level, generally within particular infraorders.
The supertree analysis currently favors Ptychopteromorpha+Culicomorpha as the sister group to the remaining Diptera with Blepharicerimorpha and Bibionomorpha being the next lineages to emerge from the Lower Dipteran stem.
Close to the grade transition to Brachycera, the Lower Dipteran infraorders are not monophyletic, with Psychodomorpha and Tipulomorpha forming a paraphyletic grouping, the superfamily Tipuloidea being sister to the Brachycera.

There are two separate infraorders of anthropoidea that have evolved independently: Catarrhines and Platyrrhines.
They have a flat nose with widely placed nostrils and a prehensile tail that is used as a ‘third hand’.
These two infraorders have evolved separately for 30,000,000 years, and they differ greatly according to the level of development.

In an effort to rectify the fossil and recent classifications of scorpions, which were hitherto incompatible (Kjellesvig-Waering, 1986), I proposed to raise the Scorpionida to the rank of class with three orders, Protoscorpiones, Palaeoscorpiones, and Scorpiones (Stockwell 1989).
The strictly phenetic suborders and infraorders of Kjellesvig-Waering (1986) were largely abandoned.
