Miriholcorpa
''Miriholcorpa'' is an extinct genus of scorpionfly (Mecoptera) from the Middle Jurassic period of China. The type and only species is ''M. forcipata'', described in 2013. Discovery ''Miriholcorpa'' was discovered in the Jiulongshan Formation at Daohugou Village of Ningcheng County in Inner Mongolia, China. The fossil is late Middle Jurassic in age, from the Callovian–Bathonian boundary (c. 165 million years ago). The genus name derives from the Latin ''miri'' meaning amazing, in reference to the high-quality preservation, and ''Holcorpa'', the type genus of the extinct Mecopteran family Holcorpidae, to which ''Miriholcorpa'' shows similarities. The specific epithet ''forcipata'', is Latin for pincer-like, in reference to the pincer-like structures on the genitalia. Description The holotype is 32.7 mm from head to the tip of the genital bulb. The left forewing, abdominal segments and genitalia are well preserved, while the venation of both hind wings are only partial ...

Holcorpidae
Holcorpidae is an extinct family of scorpionfies. It contains two genera, '' Conicholcorpa'' which is known from the Middle Jurassic Daohugou beds of Inner Mongolia, China, and '' Holcorpa,'' known from the Eocene of North America, including the McAbee Fossil Beds of British Columbia, and the Florissant Formation The Florissant Formation is a sedimentary geologic formation outcropping around Florissant, Teller County, Colorado. The formation is noted for the abundant and exceptionally preserved insect and plant fossils that are found in the mudstones an ... of Colorado. Members of this family are distinguished by their unusually long male genitalia, as well as characteristics of their wing venation. Both '' Miriholcorpa'' and '' Fortiholcorpa'' from the Middle Jurassic of China also have affinities to this family, but the incompleteness of their remains and differences from known holcorpids make their placement uncertain.

Daohugou Village
The Haifanggou Formation (), also known as the Jiulongshan Formation (), is a fossil-bearing rock deposit located near Daohugou () village of Ningcheng County, in Inner Mongolia, northeastern China. The formation consists of coarse conglomerates, sandstone, mudstone, and thin coal layers deposited in deltaic and lacustrine environments. The formation dates to the Callovian of the Middle Jurassic to the Oxfordian of the Late Jurassic. The most prominent locality of the Haifanggou Formation are the Daohugou Beds, located near the village of Daohugou in southeastern Inner Mongolia. Other localities include Wuhuaxigou, Chentaizi, Jiangzhangzi, Wubaiding, Guancaishan, Haifenggou, Fanzhangzi, and Zhuanshanzi. Dating Daohugou bed The age of the Daohugou bed has been debated, and a number of studies, using different methodologies, have reached conflicting conclusions.

Mecoptera
Mecoptera (from the Greek: ''mecos'' = "long", ''ptera'' = "wings") is an order of insects in the superorder Endopterygota with about six hundred species in nine families worldwide. Mecopterans are sometimes called scorpionflies after their largest family, Panorpidae, in which the males have enlarged genitals raised over the body that look similar to the stingers of scorpions, and long beaklike rostra. The Bittacidae, or hangingflies, are another prominent family and are known for their elaborate mating rituals, in which females choose mates based on the quality of gift prey offered to them by the males. A smaller group is the snow scorpionflies, family Boreidae, adults of which are sometimes seen walking on snowfields. In contrast, the majority of species in the order inhabit moist environments in tropical locations. The Mecoptera are closely related to the Siphonaptera (fleas), and a little more distantly to the Diptera (true flies). They are somewhat fly-like in appearance, ...

Fortiholcorpa Paradoxa
''Fortiholcorpa paradoxa'' is an extinct species of scorpionfly (Mecoptera) from the Middle Jurassic of China. It is the only known species of its genus. Discovery ''Fortiholcorpa'' was discovered in the Jiulongshan Formation at Daohugou Village of Ningcheng County in Inner Mongolia, China. The fossil is late Middle Jurassic in age, from the Callovian–Bathonian boundary (c. 165 million years ago). The genus name is a combination of Latin ''fortis'' (meaning strong, in reference to the "exceedingly elongate terminal abdominal segments and enlarged genitalia") and ''Holcorpa'' another Mecopteran with which ''Fortiholcorpa'' shows similarities. The specific epithet ''paradoxa'' means amazing, in reference to the very long abdominal segments. Description The holotype is a male 73.5 mm in length from head to genital tip. The thorax is poorly preserved, with only the mesothorax and metathorax recognizable. The 7th and 8th abdominal segments are exceedingly long in comparison t ...

Incertae Sedis
' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by ' (of uncertain family), ' (of uncertain suborder), ' (of uncertain order) and similar terms. Examples *The fossil plant '' Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Bocage's longbill, ''Motacilla bocagii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intrasexual Competition
Male-male intrasexual competition occurs when two males of the same species compete for the opportunity to mate with a female. Sexually dimorphic traits, size, sex ratio, and the social situation may all play a role in the effects male-male competition has on the reproductive success of a male and the mate choice of a female. Larger males tend to win male-male conflicts due to their sheer strength and ability to ward off other males from taking over their females. For instance, in the fly ''Dryomyza anilis'', size shows the strongest correlation to the outcome of male-male conflicts over resources like territory and females. Influencing factors Sex ratio There are multiple types of male-male competition that may occur in a population at different times depending on the conditions. Competition variation occurs based on the frequency of various mating behaviours present in the population. One factor that can influence the type of competition observed is the population density of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pincer (biology)
A pincer is the part of an arthropod that enables it to carry loads, to defend against other creatures, or to attack prey. In insects, the pincers are usually part of the creature's mandible, and often venom or acid can be injected through the pincer into an enemy during a pincer strike. Some arthropods such as crabs, lobsters, and scorpions possess pincers in the form of chelae at the ends of their front limbs (pedipalps), to assist in feeding, defence or even courtship. See also * Chela (organ) * Krukenberg procedure * Pedipalp * Pincer (tool) Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cut or pull an object. Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an ... References {{reflist Arthropod anatomy ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...
