Mengenillidae
Mengenillidae is a family of insects belonging to the order Strepsiptera. It is the second most basal member of the order, after Bahiaxenidae. Unlike members of Stylopidia, which contains the vast majority of strepsipterans, the adult females of the family are free-living with legs. Members of the family with known hosts ('' Eoxenos'' and '' Mengenilla'') parasitise members of the family Lepismatidae (silverfish The silverfish (''Lepisma saccharinum'') is a species of small, primitive, wingless insect in the order Zygentoma (formerly Thysanura).

Strepsiptera
The Strepsiptera are an order of insects with eleven extant families that include about 600 described species. They are endoparasites in other insects, such as bees, wasps, leafhoppers, silverfish, and cockroaches. Females of most species never emerge from the host after entering its body, finally dying inside it. The early-stage larvae do emerge because they must find an unoccupied living host, and the short-lived males must emerge to seek a receptive female in her host. They are believed to be most closely related to beetles, from which they diverged 300–350 million years ago, but do not appear in the fossil record until the mid-Cretaceous around 100 million years ago. The order is not well known to non-specialists, and the nearest they have to a common name is stylops. The name of the order translates to "twisted wing"', giving rise to other common names used for the order, twisted-wing insects and twisted-winged parasites. Adult males are rarely observed, although specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepismatidae
Lepismatidae is a family of primitive wingless insects with about 190 described species. This family contains the two most familiar members of the order Zygentoma: the silverfish (''Lepisma saccharinum'') and the firebrat (''Thermobia domestica''). It is one of five families in the order Zygentoma. Lepismatids are elongated, flattened insects, the majority of which are scavengers. The abdomen is usually clothed in tiny scales and terminates with three "tails" of roughly equal length. The compound eyes are small and well separated. They typically live in warm, damp environments, including indoors. They avoid light. Parasites Member of Strepsiptera family Mengenillinidae exclusively parasitise members of Lepismatidae. Host-species relationships include: ''Eoxenos laboulbenei'' on '' Tricholepisma aureum'', '' Neoasterolepisma wasmanni'' and ''N. palmonii''; ''Mengenilla parvula'' on ''Sceletolepisma michaelseni''; ''Mengenilla nigritula'' on ''Ctenolepisma ciliatum'' and ''Ctenol ...

Insects
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a phylogenetic tree#Rooted tree, rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, Phylogenetic diversity, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and cladogenesis, diversification. However, such a correlation does not make a given ca ...

Bahiaxenidae
''Bahiaxenos relictus'' is the sole member of the family Bahiaxenidae, a type of winged insect. It was only discovered and described in 2009 from relictual sand dunes associated with the Rio São Francisco in Bahia, Brazil. It is considered to be the most basal living member of the order Strepsiptera, so is the sister taxon to the remaining extant species Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, ''recent'') organisms.

Silverfish
The silverfish (''Lepisma saccharinum'') is a species of small, primitive, wingless insect in the order Zygentoma (formerly Thysanura). Its common name derives from the insect's silvery light grey colour, combined with the fish-like appearance of its movements. The scientific name (''L. saccharinum'') indicates that the silverfish's diet consists of carbohydrates such as sugar or starches. While the common name ''silverfish'' is used throughout the global literature to refer to various species of Zygentoma, the Entomological Society of America restricts use of the term solely for ''Lepisma saccharinum''. Description The silverfish is a nocturnal insect typically long. Its abdomen tapers at the end, giving it a fish-like appearance. The newly hatched are whitish, but develop a greyish hue and metallic shine as they get older. It has two long cerci and one terminal filament at the tip of the abdomen between the cerci. It also has two small compound eyes, although other mem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
