Palaeontinidae, commonly known as giant cicadas, is an extinct family of cicadomorphs. They existed during the Mesozoic era of Europe, Asia, and South America.^[1] The family contains around 30 to 40 genera and around a hundred species.^[2]

Discovery

The first palaeontinid discovered was Palaeontina oolitica . It consisted of a single forewing ^[3] collected from the Taynton Limestone Formation (Stonesfield Slate) of Oxfordshire, England by the English natural historian Edward Charlesworth. It was first described in 1873 by the English entomologist Arthur Gardiner Butler in his book Lepidoptera Exotica; or, Descriptions and Illustrations of Exotic Lepidoptera. Butler claimed that it was the oldest butterfly ever recovered, having mistakenly identified it as a butterfly of the family Nymphalidae.^[4]

Description and paleobiology

Palaeontinids had large bodies covered with bristles (setae). They had small heads and broad wings. They superficially resemble moths.^[5]^[6] Large palaeontinids like Colossocossus had forewings that reached the length of 57 to 71 mm (2.2 to 2.8 in).^[7] They possessed an inflated frons and a long rostrum (piercing and sucking mouthpart), indicating that they fed on xylem fluids like some other modern hemipterans.^[8]

Some authors have proposed that the host plants of palaeontinids to be ginkgophytes based on the geographic distribution of both groups, however other authors have argued that this association is likely to be spurious, given that that paleontinids also occur in areas with no ginkgophytes. Some authors have suggested that the decline of gymnosperms and the rise of angiosperms (flowering plants) during the Cretaceous could have been a factor in their extinction.^[7] Numerous newly evolved insectivorous animals (feathered theropods, primitive mammals, and early birds) may have also contributed significantly to their extinction.^[9]

Most species of palaeontinids exhibit cryptic coloration.^[10] The patterns on their wings protected them as they perched on branches and fed on sap. They may also have served as secondary sexual characteristics. The color patterns can vary slightly within the same species.^[8]

Palaeontinids, like modern cicadas, possess four membranous wings supported by veins. The length and width ratio of the wings can vary within the same species, sometimes as a result of fossil preservation.^[8] Early Jurassic palaeontinids, like Suljuktocossus , exhibit the most primitive wing forms in the family.^[11] The forewing was elliptical with the "nodal line" (the area where the wing bends during flight, also known as the "transverse flexion line") more or less dissecting through the center of the wing. The hindwing was short and broad. The bases of the forewings overlapped that of the hindwings like in modern butterflies. Taken together with their large bodies, these characteristics indicate that they were fast but moderately versatile fliers.^[12]

In contrast, later palaeontinids like the Upper Jurassic Eocicada and Early Cretaceous Ilerdocossus had triangular forewings with the flexion line closer to the base. They had smaller and narrower hindwings that did not overlap with the forewing. These indicate that they were highly versatile fliers, able to fly with a wide range of speeds and agility like modern wasps and sphinx moths.^[12] They also possessed changes to the leading edge of their forewings, suggesting an overall gain in lift.^[11]

The trend of forewing elongation is most evident in members of the family Mesogereonidae, an early offshoot and close relatives of palaeontinids.^[13]

The family was first erected by the Austrian entomologist Anton Handlirsch in 1908. Like Butler, Handlirsch insisted that palaeontinids were members of lepidopteran Heteroneura (butterflies and moths). Palaeontinids were then only known mostly from poorly preserved specimens like Palaeontina and Eocicada . He claimed they were related to the extant family Limacodidae (slug moths).^[14] The English entomologist Edward Meyrick supported the lepidopteran conclusion, though he believed they belonged to the family Hepialidae (ghost moths) instead. He said "There is little doubt that it [i.e. Palaeontina oolitica] belongs to the Hepialidae."^[3]

The Belgian entomologist Auguste Lameere challenged this conclusion, claiming palaeontinids were more closely related to the extant family Cicadidae (cicadas). The English-Australian entomologist and geologist Robert John Tillyard supported Lameere's conclusion, noting that the wings of palaeontinid fossils lacked the characteristic scales of lepidopterans but instead had tubercules, pits, and cross-ridges like those found in modern cicadas.^[14] He also cited characteristics of wing venation that distinctly differs from that of lepidopterans.^[3]

Palaeontinidae are currently classified under the extinct superfamily Palaeontinoidea along with the families Dunstaniidae and Mesogereonidae.^[11] They are classified under infraorder Cicadomorpha of the hemipterans (true bugs).^[15]

The name Cicadomorphidae was once proposed as a replacement for the name Palaeontinidae in 1956 by the Australian entomologist J.W. Evans. This was because of Handlirsch's earlier insistence that the type species Palaeontina oolitica may not have been Hemipteran. However, Evans later conceded that retaining the name Palaeontinidae was preferable as the drawings Handlirsch based his conclusions on were from badly preserved specimens.^[16]

Evolution

Riek (1976) originally considered Palaeontinoidea to be the descendants of the family Cicadoprosbolidae (currently known as the family Tettigarctidae), insects believed to be transitional between the ancestral cicada-like family Prosbolidae and the modern family Cicadidae.^[11]

Wang et al (2009), however, notes that palaeontinoids more closely resemble prosbolids in agreement with earlier studies by Wootton (1971), Shcherbakov (1984), and Shcherbakov and Popov (2002). They conclude that palaeontinoids descended directly from the family Prosbolidae rather than from tettigarctids.^[11] Modern cicadas therefore, did not descend directly from Palaeontinidae.

Within Palaeontinoidea, the family Dunstaniidae (Upper Permian to Lower Jurassic of Australia, South Africa, and China) is ancestral to palaeontinids. Both are distinct from the only other member of the superfamily, the more primitive and specialized family Mesogereonidae (Upper Triassic of Australia and South Africa).^[11]

Distribution and geologic time range

The oldest known member of the group is Hallakkungis from South Korea dating to the Norian stage of the Late Triassic (ca. 227 – ca. 208.5 Mya)^[17] and the youngest members are from the late Aptian age of the Lower Cretaceous (~115-113 Mya).^[9]^[15] They achieved their greatest diversity during the Jurassic period.^[18]

Palaeontinid fossils are abundant in Eurasia and South America.^[11] Fossils have been recorded in Brazil, China, Russia, Germany, the Transbaikal region, Tajikistan, Turkmenistan, Kyrgyzstan, Kazakhstan, Spain, and the United Kingdom. Important localities for palaeontinid fossils include the Crato Formation Lagerstätte of Brazil and the Yixian Formation, Haifanggou (or Jiulongshan) Formation, and the Daohugou Beds of China.^[7]^[8]^[19]

Bittacidae is a family of scorpionflies commonly called hangingflies or hanging scorpionflies.

The Ptychopteridae, phantom crane flies, are a small family of nematocerous Diptera. Superficially similar in appearance to other "tipuloid" families, they lack the ocelli of the Trichoceridae, the five-branched radial vein of the Tanyderidae, and the two anal veins that reach the wing margins of the Tipulidae. They are usually allied with the Tanyderidae based on similarities of the mesonotal suture, this group being called the Ptychopteromorpha.

<span class="mw-page-title-main">Cicadomorpha</span> Infraorder of insects

Cicadomorpha is an infraorder of the insect order Hemiptera which contains the cicadas, leafhoppers, treehoppers, and spittlebugs. There are approximately 35,000 described species worldwide. Distributed worldwide, all members of this group are plant-feeders, and many produce either audible sounds or substrate vibrations as a form of communication. The earliest fossils of cicadomorphs first appear during the Late Permian.

The Tettigarctidae, known as the hairy cicadas, are a small relict family of primitive cicadas. Along with more than 20 extinct genera, Tettigarctidae contains a single extant genus, Tettigarcta, with two extant species, one from southern Australia and one from the island of Tasmania. Numerous fossil species have been described from the Late Triassic onwards. Tettigarcta are the closest living relatives of the true cicadas.

Anaxyelidae is a family of incense cedar wood wasps in the order Hymenoptera. It contains only one living genus, Syntexis, which has only a single species, native to Western North America. Fossils of the family extend back to the Middle Jurassic, belonging to over a dozen extinct genera, with a particularly high diversity during the Early Cretaceous. Syntexis lay eggs in the sapwood of conifers, preferring recently burnt wood.

Osmylidae are a small family of winged insects of the net-winged insect order Neuroptera. The osmylids, also called lance lacewings, stream lacewings or giant lacewings, are found all over the world. There are around 225 extant species.

Nymphidae, sometimes called split-footed lacewings, are a family of winged insects of the order Neuroptera. There are 35 extant species native to Australia and New Guinea.

Coptoclavidae is an extinct family of aquatic beetles in the suborder Adephaga. The Coptoclavidae lived from the Late Triassic to the Early Cretaceous. Coptoclavidae is a member of the adephagan clade Dytiscoidea, which contains other aquatic beetles. Suggested reasons for their extinction to include the rise of teleost fish, or competition with Gyrinidae and Dytiscidae, which possess defensive secretions and sucking channels in the mandibles of larvae, which coptoclavids likely lacked. It has been suggested that the genus Timarchopsis and the subfamily Timarchopsinae are only distantly related to other coptoclavids based on cladistic analysis, with Timarchopsis being more closely related to geadephagans like carabids and trachypachids instead. Another study also suggested similarly for Coptoclavisca and possibly other coptoclaviscines.

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.

Palaeontinoidea is an extinct superfamily of cicadomorph hemipteran insects. This superfamily contains three families.

The Stenophlebiidae is an extinct family of medium-sized to large fossil odonates from the Upper Jurassic and Cretaceous period that belongs to the damsel-dragonfly grade ("anisozygopteres") within the stem group of Anisoptera. They are characterized by their long and slender wings, and the transverse shape of the discoidal triangles in their wing venation.

The Progonocimicidae are an extinct family of true bugs in the suborder Coleorrhyncha. Progonocimicidae fossils have been found in Europe, Asia, Australia, and South America.

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"

Sinoalidae is an extinct family of froghoppers known from the late Middle Jurassic to the early Late Cretaceous of Asia. They are one of two main Mesozoic families of froghoppers, alongside Procercopidae, unlike Procercopidae, Sinoalidae is thought to be an extinct side branch and not ancestral to modern froghoppers. Sinoalids have a temporally disjunct distribution being only known from the late Middle Jurassic (Callovian) Yanliao Biota of Inner Mongolia and the early Late Cretaceous (Cenomanian) aged Burmese amber of Myanmar, separated by over 60 million years. The family is "recognized by its tegmen with the costal area and clavus commonly more sclerotized and punctate than the remaining part, and its hind tibia with two rows of lateral spines"

Archijassidae is an extinct family of leafhoppers known from the Late Triassic to the early Late Cretaceous. It is the oldest member of Membracoidea, and is considered ancestral to modern leaf and treehoppers.

<span class="mw-page-title-main">Procercopidae</span> Extinct family of true bugs

Procercopidae is an extinct family of froghoppers. They are known from the Early Jurassic to early Late Cretaceous of Eurasia. They are one of two main families of Mesozoic froghoppers alongside Sinoalidae. Procercopidae are considered to be the ancestral group from which modern froghoppers are derived.

Elcanidae are an extinct family of Mesozoic and early Cenozoic orthopterans. Members of the family are distinguished by the presence of spurs on the distal part of the metatibia, unique among orthopterans, these have been suggested to have been used for controlling gliding, swimming aids, or for jumping on water. The group combines characteristics from both major groups of orthopterans, with long antennae and nymphal morphology similar to Ensifera, but with wing venation and adult morphology more similar to Caelifera. Their closest relatives are the extinct family Permelcanidae, known from the Early-Late Permian, with which they form the superfamily Elcanoidea, whose relationship to Ensifera and Caelifera are unresolved. Elcanids are known from the Late Triassic to Paleocene of Eurasia, North and South America. Some members of the group exhibited aposematic coloration.

Fulgoridiidae are an extinct family of Mesozoic planthoppers. They are the earliest group of planthoppers known, and appear to be a paraphyletic assemblage ancestral to living planthoppers. The majority of known members of the family lived in the Jurassic period, though the group also includes one Cretaceous taxon. All currently known species are from Eurasia.

Mesochrysopidae is an extinct family of lacewings known from the Jurassic and Cretaceous periods. They are considered to be closely related to green lacewings of the family Chrysopidae. The family are also alternatively considered a paraphyletic grade leading up to crown Chrysopidae.

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.
