The Superclass Panhexapoda is further organized into finer groupings including:
- Series (10): Aculeata · Bombyciformes · Cossiformes · Gracillariiformes · Hesperiiformes · Limacodiformes · Papilioniformes · Parasitica · Saturniiformes · Tineiformes
- Class (4): Bivalvia · Entognatha · Insecta · Oligohymenophorea
Classes
Bivalvia
Bivalves are marine and freshwater belonging to the class Bivalvia. Other names for the class include Bivalva, Pelecypoda, and Lamellibranchia. The class contains 30,000 species, including scallops, clams, oysters and mussels. [more]
Entognatha
Insecta
Insects ( Insecta) are arthropods, having a hard exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. They are the most diverse group of animals on the planet and include approximately 30 Notoptera, 35 Zoraptera, 150 snakefly, 200 silverfish, 300 alderfly, 300 webspinner, 350 jumping bristletail, 550 scorpionfly, 600 Strepsiptera, 1,200 caddisfly, 1,700 stonefly, 1,800 earwig, 2,000 flea, 2,200 mantis, 2,500 mayfly, 3,000 louse, 3,000 walking stick, 4,000 cockroach, 4,000 lacewing, 4,000 termite, 5,000 dragonfly, 5,000 thrips, 5,500 booklouse, 20,000 cricket, grasshopper, and locust, 82,000 true bug, 110,000 ant, bee, sawfly, and wasp, 120,000 true fly, 170,000 butterfly and moth, and 360,000 beetle species described to date. The number of extant species is estimated at between six and ten million, with over a million species already described. Insects represent more than half of all known living organisms and potentially represent over 90% of the differing life forms on Earth. Insects may be found in nearly all environments, although only a small number of species occur in the oceans, a habitat dominated by another arthropod group, the crustaceans. [more]
Oligohymenophorea
The Oligohymenophorea are a large class of protozoa. There is typically a ventral groove containing the mouth and distinct oral cilia, separate from those of the body. These include a paroral membrane to the right of the mouth and membranelles, usually three in number, to its left. The cytopharynx is inconspicuous and never forms the complex cyrtos found in similar classes. Body cilia generally arise from monokinetids, with dikinetids occurring in limited distribution over part of the body. [more]
At least 160 species and subspecies belong to the Class Oligohymenophorea.
