Caenoidea
Caenoidea is a superfamily of mayflies in the suborder Pannota. Members of this superfamily can be distinguished from those of Ephemerelloidea by the fact that the gills of the nymphs are filamentous. The following families are recognised: *Baetiscidae *Caenidae * Neoephemeridae *Prosopistomatidae Prosopistomatidae is a family of mayflies. There is one extant genus, '' Prosopistoma,'' with several dozen species found across Afro-Eurasia and Oceania.

Mayfly
Mayflies (also known as shadflies or fishflies in Canada and the upper Midwestern United States, as Canadian soldiers in the American Great Lakes region, and as up-winged flies in the United Kingdom) are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families. Mayflies have ancestral traits that were probably present in the first flying insects, such as long tails and wings that do not fold flat over the abdomen. Their immature stages are aquatic fresh water forms (called "naiads" or "nymphs"), whose presence indicates a clean, unpolluted and highly oxygenated aquatic environment. They are unique among insect orders in having a fully winged terrestrial preadult stage, the subimago, which moults into a sexually mature adult, the imago. Mayflies "hatch" (emerge ...

Pannota
Pannota is a suborder of mayflies. One of the differences between this suborder and its sister group Schistonota concerns the degree of fusion of the wing pads in the final-stage nymph; in Schistonota, the degree of fusion along the mesothorax is more than half the fore-wing length while in Pannota the degree of fusion is less than half that length. Other differences between the two groups include the morphology of the gills and also behavioural differences. Schistonota nymphs are mostly active swimmers, burrowers and sprawlers, while Pannota nymphs are more passive, slow-moving crawlers. The following superfamilies and families are recognised: *Superfamily Caenoidea **Baetiscidae **Caenidae ** Neoephemeridae **Prosopistomatidae *Superfamily Ephemerelloidea **Ephemerellidae **Leptohyphidae **Tricorythidae Tricorythidae is a family of mayflies in the order Ephemeroptera. There are about six genera and at least 40 described species in Tricorythidae. Genera These six genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ephemerelloidea
''Ephemerelloidea'' is a superfamily of mayflies in the suborder Pannota. It is a basal group of mayflies with a worldwide distribution. Members of this super-family can be distinguished from those of Caenoidea by the fact that the gills of the nymphs are not filamentous. The following families are recognised: *Ephemerellidae *Leptohyphidae Leptohyphidae is a family of mayfly, mayflies with some 140 described species in 12 genera.

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

Baetiscidae
Baetiscidae is a family of mayflies. It contains a single extant genus, ''Baetisca'', native to North America with around 12 species. The family is noted for their spined armoured larvae, which live in flowing water pools and on the edges of streams where they are detritivores, consuming fine particles of organic matter. Two other extinct genera are known, extending back to the Early Cretaceous. They are closely related to Prosopistomatidae which have unusual, beetle-like nymphs as well as the extinct genus '' Cretomitarcys,'' with the three groups constituting the clade Carapacea. Genera These two genera belong to the family Baetiscidae: * ''Baetisca'' Walsh, 1862 * †'' Balticobaetisca'' Staniczek & Bechly, 2002 Baltic amber, Eocene * †'' Protobaetisca'' Staniczek 2007 Crato Formation, Brazil, Early Cretaceous (Aptian The Aptian is an age in the geologic timescale or a stage in the stratigraphic column.

Caenidae
Caenidae, or the small squaregill mayflies, is a family of insects consisting of 5 genera comprising 26 individual species. They are found throughout the world in lotic, depositional environments, and they are sprawlers. Caenids occur in quiet and even stagnant water and are often overlooked because they are so small. They like to live in silty bottoms, and their gills are specially adapted for such environments. References Mayflies Insect families {{mayfly-stub ...

Neoephemeridae
Neoephemeridae is a family of large squaregill mayflies in the order Ephemeroptera. There are at least four genera and about 17 described species in Neoephemeridae. Genera These four genera belong to the family Neoephemeridae: * '' Leucorhoenanthus'' Lestage, 1930 * '' Neoephemera'' McDunnough, 1925 (large squaregill mayflies) * '' Ochernova'' Bae & McCafferty, 1998 * '' Potamanthellus'' Lestage, 1930 References Further reading * * * * Mayflies Insect families Articles created by Qbugbot {{mayfly-stub ...

Prosopistomatidae
Prosopistomatidae is a family of mayflies. There is one extant genus, '' Prosopistoma,'' with several dozen species found across Afro-Eurasia and Oceania. They are noted for their unusual beetle-shaped larvae, which live beneath rocks and stones along the gravelly lower reaches of rivers. Their ecology is unclear, but they are probably carnivorous. They are closely related to Baetiscidae, with both families being placed in the Carapacea. Genera These four genera belong to the family Prosopistomatidae: * '' Prosopistoma'' Latreille, 1833 * †'' Proximicorneus'' Lin et al., 2017 Burmese amber Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar.
