Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
Whiteflies are Hemipterans that typically feed on the undersides of plant leaves. They comprise the family Aleyrodidae, the only family in the superfamily Aleyrodoidea. More than 1550 species have been described.
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 described species.
The Lygaeoidea are a sizeable superfamily of true bugs, containing seed bugs and allies, in the order Hemiptera. There are about 16 families and more than 4,600 described species in Lygaeoidea, found worldwide. Most feed on seeds or sap, but a few are predators.
The Sternorrhyncha suborder of the Hemiptera contains the aphids, whiteflies, and scale insects, groups which were traditionally included in the now-obsolete order "Homoptera". "Sternorrhyncha" refers to the rearward position of the mouthparts relative to the head.
Coreinae is a subfamily in the hemipteran family Coreidae. They have been shown to be paraphyletic with respect to Meropachyinae.
Schizopteridae is the largest family in the infraorder Dipsocoromorpha and comprises 56 genera and approximately 255 species. Schizopterids are some of the smallest (0.5–2.0 mm) true bugs. Members of this family can be distinguished by their small size, enlarged forecoxae and varying degree of abdominal and genitalic asymmetry in males. Schizopteridae exhibit a wide range of simple and complex wing venation patterns. The group is currently divided into three subfamilies: Schizopterinae, Ogeriinae and Hypselosomatinae.
Burmacoccus is an extinct genus of scale insect in the extinct monotypic family Burmacoccidae, containing a single species, Burmacoccus danyi. The genus is solely known from the Albian – Cenomanian Burmese amber deposits.
Albicoccus is an extinct genus of scale insect in the extinct monotypic family Albicoccidae, containing a single species, Albicoccus dimai. The genus is solely known from the Albian - Cenomanian Burmese amber deposits.
Marmyan is an extinct genus of scale insect, containing a single species, Marmyan barbarae and unplaced in any coccid family. The genus is solely known from the Albian – Cenomanian Burmese amber deposits.
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected.
Parvaverrucosa is an insect genus in the extinct, monotypic family Parvaverrucosidae, of the order Hemiptera. It contains the monotypic species Parvaverrucosa annulata known from the Cenomanian aged Burmese amber of Myanmar. First described in 2005, the genus was redescribed in 2019, which found it to be in the superfamily Palaeoaphidoidea
2019 in paleoentomology is a list of new fossil insect taxa that were described during the year 2019, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
2020 in paleoentomology is a list of new fossil insect taxa that were described during the year 2020, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
Mimarachnidae is an extinct family of planthoppers known from the Cretaceous period. Their name is derived from spots on the wings of the first described genera, Mimarachne and Saltissus, being suggestive of spider mimicry, but these characters are not distinctive for the family as a whole. The family is characterised by "simplified venation and setigerous metatibial pecten and hind leg armature". as well as "rounded anterior margin of pronotum, double carination of pronotum and mesonotum"
Yuripopovinidae is an extinct family of Coreoidea Hemipteran true bugs. Member species are known from the Early Cretaceous and early Late Cretaceous of Asia and northern Gondwana. Among the distinguishing characters are "the hemelytral costal vein apically much thickened and pterostigma-like, the corium with two large cells separated by one longitudinal straight vein." Dehiscensicoridae, described from the Yixian Formation of China has been deemed a junior synonym of Yuripopovinidae per Du et al. (2019). The family was named after Russian paleoentomologist Yuri Alexandrovich Popov.
Perforissidae is an extinct family of planthoppers. They are considered to belong to the group of "Cixiidae-like" planthoppers. Species are known from the Early to Late Cretaceous of Eurasia, North America and South America. The family was named by Shcherbakov in 2007
This paleoentomology list records new fossil insect taxa that were to be described during the year 2021, as well as notes other significant paleoentomology discoveries and events which occurred during that year.
Liadopsyllidae is an extinct family of hemipteran insects belonging to Psylloidea ranging from the Early Jurassic to Upper Cretaceous. The family was named by Andrey Vasilyevich Martynov in 1926. They are the earliest known members of Psylloidea, with modern members of the group not known until the Paleogene, as such, they have been suggested to be a paraphyletic assemblage ancestral to modern psylloids. The family Malmopsyllidae has been subsumed into this family, but is considered distinct by some authors.
